LAS CRUCES, N.M. - A 7-year-old girl who crossed the U.S.-Mexico border with her father last week died after being taken into the custody of the U.S. Border Patrol, federal immigration authorities confirmed Thursday.
The Washington Post reports the girl died of dehydration and shock more than eight hours after she was arrested by agents near Lordsburg, New Mexico. The girl was from Guatemala and was traveling with a group of 163 people who approached agents to turn themselves in on Dec. 6.
Early Dec. 7, the girl started having seizures, and emergency responders measured her body temperature at 105.7 degrees, the Post said. She was taken to a hospital, where she died, according to the Post.
It's unknown what happened to the girl during the eight hours before she started having seizures and was flown to an El Paso hospital.
A spokesman at Providence Hospital in El Paso, Texas, where the Post reported the child was taken, also did not immediately respond to a request for comment.
The names of the girl and her father were not released. The agency, which typically provides food and water to migrants in its custody, is investigating the incident to ensure appropriate policies were followed, the Post said.
In a statement, Customs and Border Protection said the girl had not eaten or consumed water in several days. The agency did not provide The Associated Press with the statement it gave to the Post, despite repeated requests.
Large groups pose challenges
Processing 163 immigrants in one night could have posed challenges for the agency, whose detention facilities are meant to be temporary and don't usually fit that many people.
When a Border Patrol agent arrests someone, that person is processed at a facility but usually spends no more than 72 hours in custody before they are either transferred to Immigration and Customs Enforcement or, if they're Mexican, quickly deported home.
The girl's death raises questions about whether border agents knew she was ill and whether she was fed anything or given anything to drink during the eight-plus hours she was in custody.
Troubles in Tucson Sector
Immigrants, attorneys and activists have long raised issues with the conditions of Border Patrol holding cells. In Tucson, an ongoing lawsuit claims holding cells are filthy, extremely cold and lacking basic necessities such as blankets. A judge overseeing that lawsuit has ordered the agency's Tucson Sector, which patrols much of the Arizona-Mexico border, to provide blankets and mats to sleep on and to continually turn over surveillance footage from inside the cells.
The Border Patrol has seen an increasing trend of large groups of immigrants, many with young children, walking up to agents and turning themselves in. Most are Central American and say they are fleeing violence. They turn themselves in instead of trying to circumvent authorities, many with plans to apply for asylum.
Agents in Arizona see groups of more than 100 people on a regular basis, sometimes including infants and toddlers.
Arresting such groups poses logistical problems for agents who have to wait on transport vans that are equipped with baby seats to take them to processing facilities, some which are at least half hour north of the border.
Toddler died in May
The death of the 7-year-old comes after a toddler died in May just after being released from an ICE family detention facility in Texas, and as the administration of Donald Trump attempts to ban people from asking for asylum if they crossed the border illegally. A federal appeals court has temporarily blocked that ban, but the administration asked the U.S. Supreme Court to reinstate it Tuesday.
Cynthia Pompa, advocacy manager for the ACLU Border Rights Center, said migrant deaths increased last year even as the number of border crossing dropped.
"This tragedy represents the worst possible outcome when people, including children, are held in inhumane conditions. Lack of accountability, and a culture of cruelty within CBP have exacerbated policies that lead to migrant deaths," Pompa said.
