Environmentalists: Border fence putting Arizona pronghorns in peril

Arizona Republic
January 24, 2013
by Bob Ortega

PHOENIX -- The land where the antelope play, where Arizona meets Mexico, has been divided in recent years by taller and longer border fences.
 
They are meant to keep out or slow undocumented migrants and drug smugglers coming north from Mexico, but environmentalists say they're also helping drive two southeastern Arizona pronghorn antelope herds to the brink of dying out.
 
Environmentalists say the inability of the pronghorn — and other wildlife — to range freely across southern Arizona and northern Mexico has contributed to dramatic declines in the population of what are known as the San Rafael and Sonoita herds. From 122 animals identified in a 2005 count, the herds' numbers fell to 26 in a survey last year, according to the Arizona Game and Fish Department.
The San Rafael herd is down to an estimated eight animals, and the Sonoita herd is down to an estimated 18.
 
While the number of animals spotted can depend on weather conditions and other factors, Game and Fish doesn't consider either herd sustainable, and the agency plans to capture and transplant enough animals from the Chino Valley area, north of Prescott, to reinvigorate them.
 
But there are questions about whether the transplants will work if border fences and other pressures on the herds go unchanged.
 
Dan Millis, borderlands program coordinator for the Sierra Club, said he suspects not. However, John Millican, a project manager with the Arizona Antelope Foundation, said he thinks the border fence may actually have protected the few pronghorn that are left from being shot by poachers in northern Mexico.
 
Millican and Millis agree that better studies would help make the fence's impact clear.
 
Pronghorn (Antilocapra americana) aren't really antelope, which are found only in Africa and Asia. However, they're commonly called pronghorn antelope because they resemble true antelope in behavior and appearance. The pronghorn is the only surviving species of the antilocapridae family. They're considered the second-fastest land animal in the world, after the cheetah, with a top speed of more than 60 mph.
 
Environmental reviews skipped
 
After the Sept. 11, 2001, attacks, the Bush administration launched a massive expansion of the border wall and the Border Patrol. In 2006, Congress adopted the Secure Fence Act, and the Department of Homeland Security began contracting to build or reinforce fences in key areas along the U.S.-Mexican border, including in Arizona. Between the budget years 2008 and 2011, Customs and Border Protection spent $1.2 billion to build nearly 300 miles of fencing and roads along the U.S.-Mexican border, including areas around the Huachuca Mountains where the two pronghorn herds live.
 
To get that fencing up quickly, the Bush administration issued waivers of environmental- and endangered-species-protection laws and scrapped the environmental-impact studies and reviews that normally would have been required.
 
"We wish we had more scientific studies to point to," Millis said, "but the Department of Homeland Security has a poor environmental record. Borderwide, there's been very little funding for studies and habitat restoration and little of the due diligence that needs to be done."
 
Customs and Border Protection signed an agreement in 2009 with the Department of the Interior to fund up to $50 million in studies and projects along the border. The following year, the agencies launched $6.8 million in studies and projects along the Southwestern border. These included building a fish barrier in the San Bernardino National Wildlife Refuge, restoring habitat for long-nosed bats in Organ Pipe Cactus National Monument, and surveying and monitoring jaguars in southern Arizona.
Customs officials couldn't immediately identify further spending on border mitigation efforts.
 
Several studies that have been completed — on species such as the desert bighorn sheep in California and the cactus ferruginous pygmy owl — show that the habitats the animals need to thrive have been further fragmented. The chief causes are habitat loss due to development, habitat change from invasive plant species, the fences, the new roads along the fences and the increased Border Patrol presence.
 
The U.S. Fish and Wildlife Service has led a decadelong multiagency project focusing on Arizona’s other southern corner, near Yuma, where the population of the endangered Sonoran pronghorn, a subspecies, has rebounded from 21 animals in the wild 10 years ago to more than 100 today. In addition, there are 125 more in breeding pens near Ajo, said Jim Paxon, chief of information for the Arizona Game and Fish Department.

Customs and Border Protection declined to discuss mitigation efforts in southeastern Arizona, but pointed, in a written statement, to the recovery efforts for the Sonoran pronghorn as “an example of our commitment.” The statement added that the agency “is fully engaged in efforts that consider the environment as we work to secure our nation’s border.”

Moving forward

Game and Fish tried twice — unsuccessfully — last winter to capture pronghorn near Chino Valley, using a quarter-mile-wide V-shaped trap leading to a corral, Paxon said. Officials decided against using a helicopter with a net gun because the mortality rate for the animals can run to 20 percent, vs. 3 to 4 percent using the corral traps, he said.

The captures have been postponed until next year, said Amber Munig, big-game supervisor for Game and Fish. Because the herd there spends much of its time on federal lands, the delay gives Game and Fish time to do a survey and gain permission from the federal Bureau of Land Management.

Munig said their goal is to transplant enough animals to boost the San Rafael and Sonoita herds up to at least 50 pronghorn each.

Munig said that while she couldn’t speak to the impact of the border fence, “We are looking at habitat issues and fragmentation in that area within Arizona.” The department has been working for years with other state and federal agencies, the Arizona Antelope Foundation and local ranchers to restore habitat in the areas used by the two herds, removing invasive species such as cheatgrass and juniper that squeeze out the native plants the pronghorn eat, she said.

Millican, who worked for 30 years for Game and Fish before joining the antelope foundation, said tackling another kind of fencing also has been key to connecting the fragmented areas where the pronghorn live. Arizona’s range lands are crisscrossed with barbed wire, old and new. That’s an issue for pronghorn, which shy from roads and, though fast, are not good jumpers, Millican said.

“Even when they’re really pressured, they prefer to go under a fence,” he said. But the lowest strand of older fencing, typically 6 to 8 inches off the ground, doesn’t give them enough clearance. So a major focus is working with landowners to replace the lowest strand of barbed wire with smooth wire 16 to 18 inches off the ground, which will keep livestock in but let the pronghorn through.

Millican agrees with the Sierra Club’s Millis that the border fence causes issues with other species moving back and forth. For the pronghorn, though, he said, “We have protections in the U.S.; there aren’t a lot of protections on the Mexican side.”

He said he’s confident that with proper habitat management on the U.S. side, the border fence won’t stop the herds from thriving again.

Millis, meanwhile, argues that other agencies and groups shy away from criticizing the Department of Homeland Security because “people don’t want to mess around with security issues.”

But he said there’s no question that the border walls harm the environment, “and now Arizonans are stuck with the costs of cleaning up the mess.”

Mexican officials question border agent's use of force in boy's death in Nogales

Arizona Republic
October 13, 2012
by Bob Ortega

As more details emerge about the shooting death late Wednesday of a 16-year-old Mexican boy in Nogales, Sonora, by a Border Patrol agent, Mexican authorities increasingly are questioning whether lethal force was needed.

The FBI, and Mexican federal and state police, are carrying out parallel investigations into the incident.

Nogales Mayor Ramon Guzman Munoz told the Associated Press that Jose Antonio Elena Rodriguez was shot seven times. Various news reports by Sonora broadcasters and newspapers described anywhere from five to 14 bullet holes on the wall of the building beside which the body was found.

Elena Rodriguez's death - following more than a dozen similar incidents along the U.S.-Mexico border since 2010 - has provoked condemnation from Mexican authorities and outrage in Mexican news media, in particular over the number of times the youth allegedly was shot. Twitter messages and comments on Mexican news sites routinely condemned the shooting as an "asesinato," or murder.

This is the fifth incident in Nogales since mid-2010 in which Border Patrol officers resorted to force after youths threw rocks at them. In three of those cases, agents fired their guns, killing a 17-year-old boy in January 2011 and wounding a man in January of this year.

U.S. Customs and Border Protection spokesman Mike Friel said Saturday that the agency's "law-enforcement personnel are trained to use deadly force in circumstances that pose a threat to their lives, the lives of their fellow law-enforcement partners and innocent third parties."

Mexican officials have questioned the use of force before and filed diplomatic protests on several occasions, but Customs and Border Protection has not changed its policies on use of force in recent years, said Friel.

Sonora state police released a statement saying they found Elena Rodriguez's body, "with various gunshot wounds on different parts of the body," shortly after 11:30 p.m. Wednesday, lying next to the curb on Calle Internacional, a street that runs along the border fence. The body was found four blocks from the border crossing in downtown Nogales, at a spot where there is roughly a 10-foot vertical drop from the base of the fence to the street below.

According to the Border Patrol, several agents responded Wednesday night to reports that drug smugglers were carrying bundles into the U.S. As agents saw two men fleeing back into Mexico, people on the other side of the fence began to throw rocks at the agents. Agents ordered them to stop and when they didn't, an agent fired his weapon, hitting one of them, an agency spokesman said.

In interviews aired by several Mexican broadcasters, alleged witnesses said the youths were throwing rocks to prevent the Border Patrol from arresting the two men who were trying to climb back over the border fence after dropping bundles of drugs.

Ricardo Alday Gonzalez, a spokesman for Mexico's Embassy in Washington, D.C., said Friday that Mexican authorities will closely monitor the U.S. investigation into the incident, and cooperate with the FBI and other U.S. agencies, to "provide whatever support is necessary to ensure a transparent, exhaustive and accountable process in the United States."

He said Mexican federal and state law enforcement also "will not hesitate to request whatever assistance they require" from the FBI or other U.S. agencies.

The Border Patrol has declined to say what weapon the agent involved in Wednesday's incident fired. They also did not reply to queries about whether that agent is currently on leave.

The standard service firearm for Border Patrol agents is the .40-caliber Heckler & Koch pistol, which carries a 14-round magazine. Agents also have the option to carry an M-4 carbine identical to the one used by the U.S. Army, which has semiautomatic and automatic settings, Friel said. On the semiautomatic setting, the trigger must be pulled to fire each round; on the automatic setting, the rifle can fire multiple rounds with one pull of the trigger.

Border Patrol agents have access to non-lethal alternatives. In May of last year, for instance, a Nogales-based Border Patrol agent fired several rounds from a pepper-ball launcher at a suspected drug smuggler who was throwing rocks at him, and completed the drug seizure without injuries on either side.

Binational effort helps rescue border fence mural

Nogales International
June 21, 2011
by Jonathan Clark

A community mural painted on the border wall separating the U.S. and Mexico was saved from the scrap heap last week through a binational effort, and an artist who was integral to its creation and salvation says he hopes the artwork, which represents popular resistance, will one day rise again at its original location.

The 60-foot-long mural, titled “Vida y Sueños de la Cañada Perla,” or “Life and Dreams of the Perla Ravine,” was painted by people from both sides of the border in 2005 on the Sonoran face of the landing-mat fence running through Ambos Nogales, a few hundred yards west of the DeConcini port.

It’s a replica of a mural painted in 1998 by Tzetzal Indians on the façade of the community center of Taniperla, Chiapas to represent their lives and dreams after declaring themselves part of an autonomous Zapatista revolutionary municipality. However, on April 11, 1998, a day after the mural and the autonomous municipality were inaugurated, the Mexican Army retook control of the town, destroyed the mural and jailed the man who had directed its creation, university professor Sergio Valdez.

Nogales, Sonora-based artist Guadalupe Serrano, who along with his creative partner Alberto Morackis brought Valdez to the border city for the re-creation project in 2005, said that after U.S. crews replacing the 2.8-mile-long landing-mat fence with a taller, stronger barrier reached the downtown area last month, city officials warned him that the “Vida y Sueños” replica might also be destroyed.

At the same time, he said, he learned that wheels had also begun to turn in Arizona in an effort to save the mural.

“What happened was that in Tucson, there’s an organization called the Sierra Club, and a guy from that organization named Dan Millis got in touch with Congressman Raul Grijalva,” Serrano said.

In a letter dated June 8, Millis, along with Kim Roseman of the K. Newby Gallery in Tubac, Susannah Castro of the Tubac Center of the Arts and Bob Phillips of the Santa Cruz Community Foundation, urged Grijalva to investigate the status of “Vida y Sueños” and other nearby fence art and iconic graffiti, “and act to ensure that these cultural resources are protected for future generations.”

Grijalva responded by dispatching staffer Ruben Reyes to coordinate with the Border Patrol (a Grijalva spokesman said the agency was “very cooperative”), who then worked with contractor Granite Construction to arrange a safe takedown and handover of the mural panels to Serrano.

Early last Thursday, Serrano and members of his art collective Taller Yonke (Junk Studio) showed up at the border fence with a trailer and some tools to dismantle and haul off the mural panels after a Granite Construction crane lifted them off their footing in the United States and laid them on the ground in Mexico.

“We saved the whole mural,” Serrano said. “There were just two pieces at the end that were already gone.”

The other nearby iconography – a mural depicting a loteria card version of the floating eye pyramid, an array of white crosses representing migrant deaths and painted slogans including “Fronteras: Cicatrices en la tierra” (“Borders: Scars on the Earth”) – were not so lucky.

“Those things were in another area, and by the time we realized what was happening, ‘La Migra’ had taken them away,” Serrano said.

There was another important object, not attached to the fence but mounted directly in front of it, that Serrano was able to save: a bust of his collaborator and fellow Taller Yonke founder Morackis, who died in December 2008 from pneumonia, two days short of his 50th birthday.

Border art

Serrano and Morackis began using the Nogales landing-mat fence as a forum for socially and politically conscious art in 2003 when they unveiled “Border Dynamics,” a steel-and-resin piece depicting four, 14-foot human figures pushing against the wall. The artists initially hoped to place the figures on both sides of the fence, but the Border Patrol nixed the plan on the U.S. side, citing security concerns.

The University of Arizona later purchased “Border Dynamics” and displayed it on the campus mall in Tucson before moving it to an area next to the school’s Harvill building.

In March 2004, the artists mounted another provocative piece on the south side of the fence: a series of aluminum human figures and symbols called “Paseo de Humanidad,” or “Parade of Humanity.” Created in collaboration with Tucson-based artist Alfred J. Quiroz, the work represented the suffering of Mexican migrants as they traveled to and from the United States.

But as Serrano noted, “Border Dymanics” and “Paseo de Humanidad” were temporary exhibits at the Nogales fence. The “Vida y Sueños” mural was permanently affixed to it.

The idea for the mural project, he said, came when he met Valdez during a trip to Mexico City. Serrano knew the history of the original mural, and how communities from South America to Europe had re-created it in public spaces as a show of solidarity and resistance. So he asked Valdez to help with a re-creation on the border wall in Nogales, “for what the mural means and what the wall represents,” he said.

Aided by a patron in Hermosillo and an art collective called La Linea, Serrano and Morackis invited people from across Sonora and Southern Arizona to paint the mural in the spring of 2005.

“The only thing we did was coordinate the project,” Serrano said. “We didn’t participate in the painting – all we really did was get the paint ready and coordinate.”

The centerpiece of the colorful painting is a depiction of two doves holding banners reading “Chiapas,” “Peace” and “Mexico,” as a campesino man and woman walk toward them. Above, Emiliano Zapata, the land-reform hero of the Mexican Revolution, rides a horse and sports a bandana reading, “La tierra es de quien la trabaja,” or “The land belongs to the person who works it.”

Other images show an idyllic riverside village where people work the land and hold community meetings as ski mask-clad Zapatista guerrillas stand at the ready on nearby hillsides.

The mural’s political imagery perhaps didn’t have an immediate connection to Nogales and its border wall, Serrano said, but the history of its creation and the efforts to re-create it did.

“More than anything, it was that it was a form of resistance and a representation of what the community could accomplish,” he said. “The social issues don’t have a lot of direct relevance here, but as a representation of civil resistance, that makes it significant.”

Grijalva said the cross-border community effort that created it in Nogales, Sonora also made the local version of the mural significant, and worth saving.

“This mural tells the story of our border community just as strongly as any words,” the congressman said. “One day we’ll look back on this work of art and thank ourselves for preserving it when we had the chance.”

Future plans

As for the future, Serrano said, once the fence construction project finishes, he plans to return the bust of Morackis to its original spot in the border-side strip at the intersection of Internacional and Fenochio streets that’s informally known as the Espacio Cultural Binacional Alberto Morackis.

He’d like to mount “Vida y Sueños de la Cañada Perla” there as well, against the newer, bigger border barrier that replaced its original canvas.

“We’re going to wait for them to conclude the work, and then we’re going to have to talk with the Border Patrol to see if we'll be able to install it there again,” Serrano said, though he noted there may be resistance to the idea, since one of the reasons for the new, interconnected-pole fence was to allow Border Patrol agents to see clearly into Sonora.

“We’re going to talk with them to see if there’s any way that we can install it. If not,” he said, “we'll look for some other space to display it here in the city.”

An Arizona Morgue Grows Crowded

New York Times
July 28, 2010
by James C. McKinley

TUCSON — Dr. Bruce Parks unzips a white body bag on a steel gurney and gingerly lifts out a human skull and mandible, turning them over in his hands and examining the few teeth still in their sockets.

The body bag, coated with dust, also contains a broken pelvis, a femur and a few smaller bones found in the desert in June, along with a pair of white sneakers.

“These are people who are probably not going to be identified,” said Dr. Parks, the chief medical examiner for Pima County. There are eight other body bags crowded on the gurney.

The Pima County morgue is running out of space as the number of Latin American immigrants found dead in the deserts around Tucson has soared this year during a heat wave.

The rise in deaths comes as Arizona is embroiled in a bitter legal battle over a new law intended to discourage illegal immigrants from settling here by making it a state crime for them to live or seek work.

But the law has not kept the immigrants from trying to cross hundreds of miles of desert on foot in record-breaking heat. The bodies of 57 border crossers have been brought in during July so far, putting it on track to be the worst month for such deaths in the last five years.

Since the first of the year, more than 150 people suspected of being illegal immigrants have been found dead, well above the 107 discovered during the same period in each of the last two years. The sudden spike in deaths has overwhelmed investigators and pathologists at the Pima County Medical Examiner’s Office. Two weeks ago, Dr. Parks was forced to bring in a refrigerated truck to store the remains of two dozen people because the building’s two units were full.

“We can store about 200 full-sized individuals, but we have over 300 people here now, and most of those are border crossers,” Dr. Parks said. “We keep hoping we have seen the worst of this, of these migration deaths. Yet we still see a lot of remains.”

The increase in deaths has happened despite many signs that the number of immigrants crossing the border illegally has dropped in recent years. The number of people caught trying to sneak across the frontier without a visa has fallen in each of the last five years and stands at about half of the record 616,000 arrested in 2000.

Not only has the economic downturn in the United States eliminated many of the jobs that used to lure immigrants, human rights groups say, but also the federal government has stepped up efforts to stop the underground railroad of migrants, building mammoth fences in several border towns and flooding the region with hundreds of new Border Patrol agents equipped with high-tech surveillance tools.

These tougher enforcement measures have pushed smugglers and illegal immigrants to take their chances on isolated trails through the deserts and mountains of southern Arizona, where they must sometimes walk for three or four days before reaching a road.

“As we gain more control, the smugglers are taking people out to even more remote areas,” said Omar Candelaria, the special operations supervisor for the Border Patrol’s Tucson Sector. “They have further to walk and they are less prepared for the journey, and they don’t make it.”

Mr. Candelaria said the surge in discoveries of bodies this year might also owe something to increased patrols. He noted that some of the remains found this year belong to people who died in previous years. But Dr. Parks said that could not account for the entire increase this year. Indeed, the majority of bodies brought in during July, Dr. Parks said, were dead less than a week.

Human rights groups say it is the government’s sustained crackdown on human smuggling that has led to more deaths.

“The more that you militarize the border, the more you push the migrant flows into more isolated and desolate areas, and people hurt or injured are just left behind,” said Kat Rodriguez, a spokeswoman for the Coalición de Derechos Humanos in Tucson.

At the medical examiner’s office in Tucson, Dr. Park’s team of five investigators, six pathologists and one forensic anthropologist face an enormous backlog of more than 150 unidentified remains, with one case going back as far as 2003.

Every day, they labor to match remains with descriptions provided by people who have called their office to report a missing relative, or with reports collected by human rights groups and by Mexican authorities.

Since 2000, Dr. Park’s office has handled more than 1,700 border-crossing cases, and officials here have managed to confirm the identities of about 1,050 of the remains.

Investigators sift through the things the dead carried for clues — Mexican voter registration cards, telephone numbers scrawled on scraps of paper, jewelry, rosaries, family photographs. Often there is precious little to go on.

We had one gentleman who came in as bones, but around his wrist there was a bracelet from a Mexican Hospital that had his picture,” said David Valenzuela, one of the investigators.

If no documents are found, the task becomes harder. Many of the deceased immigrants were too poor to have visited doctors or dentists on a regular basis, so dental or medical records may not exist. Sometimes, a family photograph of the deceased smiling widely is all investigators have to document dental work.

On a recent morning, Bruce Anderson, the forensic anthropologist in the office, was examining the skeleton of an adolescent boy, whose age was somewhere between 14 and 17. His mummified remains were found on the Tohono O’odham Indian Reservation west of Tucson on July 15. The only lead to his identity was a missing front tooth and the neighboring teeth crowded together in the space.

Dr. Anderson called the Coalición de Derechos Humanos, who had a report of a 13-year-old who had been reported missing this year after crossing the border near Sonoyta, Mexico.

The charity immediately contacted the boy’s family to see if he had lost a permanent tooth. Dr. Anderson was still waiting for a reply.

The process takes time, and remains keep piling up. On Monday, Mr. Anderson faced a backlog of 14 new skeletons, in addition to the 40 active cases he is investigating, he said. “One person can’t keep up with this load,” he said.

The pathologists are also under strain. One day last week, Dr. Cynthia Porterfield did five autopsies, on remains of border crossers who died in the desert.

Dr. Porterfield was able to identify one: Jesse Palma Valenzuela, 30, who died on July 12. Three of his travel companions had tried to carry his body back to Mexico but became tired and abandoned him, wrapped in a blanket and positioned off the ground in a tree to keep animals from eating him. Then they crossed back into Mexico and notified the Border Patrol.

Agents discovered Mr. Valenzuela’s body on July 17, right where his friends said it would be, about two-and-a-half miles east of Lukeville, Ariz., not far from the border. Though decomposed, he was still recognizable.

“He’s got quite a few tattoos,” Dr. Porterfield said. “It is how the family ID’d him.”

Mexico ties flooding in Nogales to U.S. Border Patrol-built wall

Arizona Daily Star
July 23 2008

By Brady McCombs

Mexican officials say a concrete barrier constructed by the U.S. Border Patrol in a storm-water tunnel beneath Nogales appears to be on Mexican soil and was the main cause of serious flooding July 12 in Nogales, Sonora.

The flooding caused about $8 million in damage in Nogales, Sonora, the officials say.

The 5-foot-high wall on the floor of the tunnel in front of a gate was put in without notifying the International Boundary and Water Commission, said Sally Spener, spokeswoman for the U.S. section of the commission. The commission requests that any agency doing work on the border that could affect storm drainage send it plans.

"We do have concerns about structures that are placed on the international boundary that could affect storm-water flow," Spener said.

The U.S. side of the commission hasn't yet determined if the barrier caused the flooding, Spener said. It's important to remember the Mexican side of the tunnel was old and in poor condition, she said.

A delegation from the commission, including Commissioner Carlos Marin, was en route to Nogales on Tuesday.

While in Arizona, the delegation will be analyzing whether the structure is in Mexico, what role it played in the flood and what should be done to remedy the situation, she said.

Officials with the Mexican section of the commission say the barrier reduced the flow of storm water through the tunnel by 40 percent, said Jesús Quintanar, a representative in Nogales of the Mexican side of the commission. The barrier was put up in January by the Border Patrol without letting anyone else know, he said.

Border Patrol officials in the Tucson Sector referred questions to headquarters, but a message to that office got no reply.

Although built in the 1930s to channel storm runoff and prevent flooding, the tunnel beneath Nogales has been used for decades by smugglers as an avenue into the United States.

In recent years, the Border Patrol has erected two sets of heavy steel doors, designed to open when the tunnel fills with water, to make it more difficult to cross through the tunnel. There are also cameras and sensors to alert the Border Patrol when somebody is trying to cross.

The monsoon rains usually cause damage to the gates or cameras and sensors, making it easier for illegal immigrants daring enough to enter the tunnel during the rainy season. But on July 12, when heavy rains fell in the border region, the new concrete barrier served as a bottleneck, causing the water to fill up on the Mexican side of the channel and pressure the aging structure, Quintanar said.

"We can affirm, with scientific and technical data, that it obstructed the flow of water," said Quintanar. "It diminished the hydraulic capacity of the wash and caused the upper slabs of the wash to break, along with the pavement on Calle Elias, and the water flooded out."

A concrete aboveground border wall east of the wash further escalated the damage by stopping the water that spilled onto Calle Internacional and Calle Elias from flowing into the United States. The barrier in the wash, however, was the catalyst for the flood, he said.

The $8 million in damage caused by the flood includes damage to 578 homes and 45 cars, Mexican officials say. State officials have declared the damaged part of the city a disaster zone.
Two days after the flooding, U.S. officials found the bodies of two people in the wash. They suspect they were illegal immigrants trying to get through the tunnel the evening of the flooding.

After a meeting last week with the mayors from Nogales, Ariz., and Nogales, Sonora, federal officials gave permission for the cities to remove 1 1/2 feet from the concrete wall, said Octavio Garcia-Von Borstel, mayor of Nogales, Ariz.

The Border Patrol denied the requests to remove the barrier completely but didn't say why, said Marco Antonio Martínez Dabdoub, mayor of Nogales, Sonora.

Using equipment from Nogales, Ariz., and workers from Nogales, Sonora, the cities finished the work over the weekend, Garcia-Von Borstel said.

Removing some of the barrier might help slightly but is not enough to prevent future flooding in heavy rains, said Quintanar and Martínez Dabdoub.

"Until the wall is completely demolished, it will continue to be a concern for both countries," said Quintanar.

Garcia-Von Borstel supports the federal government's decision to limit the reduction of the barrier by 1 1/2 feet because he knows the wall was put in to prevent drug smuggling. Plus, he's doesn't necessarily agree that the barrier was the catalyst for the flooding.

"I think it was a combination of things together that landed us where we land today," said Garcia-Von Borstel.

At the same time, he said he would support the complete removal of the barrier to allow for better water flow. If the structure turns out to be in Mexico, Martínez Dabdoub said Mexico would demolish the barrier.

He said it appears as though the barrier is about three to five feet into Mexico, although he admitted it's difficult to make a definitive assessment because the international boundary runs diagonally in the wash.

Martínez Dabdoub said he's also evaluating a way for Nogales, Sonora, to get some re- imbursement for property damage from the United States since the barrier appears to have caused the flood.

Quintanar said he sent a report to the International Boundary and Water Commission's main office in Mexico in Ciudad Juárez documenting the damage done by the barrier.

"Irregardless of what country you are in, it's an obstruction to the flow of water," said Quintanar. "This is the commission's concern, that they install things without telling the United States section first so they can consult with the neighboring country."
