Migrant girl, 8, has died in Border Patrol custody after suffering a medical emergency

An eight-year-old girl has died while in Border Patrol custody, authorities said, a rare occurrence that comes as the agency struggles with overcrowding.

The overcrowding comes as Migrants gathered on both sides of the U.S.-Mexico border today hours before immigration laws known as Title 42 expired, with some rushing to cross ahead of tough new asylum rules that will replace the COVID-era order.

The child and her family were being held at a station in Harlingen, Texas, in Rio Grande Valley, one of the busiest corridors for illegal crossings, U.S. Customs and Border Protection, the Border Patrol's parent agency, said in a statement.

The girl - a migrant involved in the border crossings - experienced 'a medical emergency' and was taken to a nearby hospital, where she died on Wednesday, according to the statement, which did not disclose her nationality or provide additional information about the incident.

Customs and Border Protection's internal affairs office will investigate, and the Homeland Security Department's inspector general and Harlingen police have been notified, Miller said. Sgt. Larry Moore, a spokesman for the Harlingen Police Department, said he had no information about the death.

Title 42 was a pandemic-era regulation that allowed migrants to be sent straight back to Mexico without even applying for asylum.

For more than three years, Title 42 had allowed the government to quickly expel millions of migrants who illegally crossed the border before they could apply for asylum during the pandemic.

But now that Biden's administration are lifting all Covid-19 protocols, they are also lifting restricted migration - a move that has seen tens of thousands of migrants massing on the southern border in a panic. 

The Border Patrol had 28,717 people in custody on May 10, the day before pandemic-related asylum restrictions expired, which was double from two weeks earlier, according to a court filing. By Sunday, the number had dropped 23% to 22,259, still unusually high.

The average time in custody on Sunday was 77 hours, five hours more than the maximum allowed under agency policy.

Last week, the Border Patrol began releasing migrants in the U.S. without notices to appear in immigration court, instead directing them to report to an immigration office within 60 days. The move spares Border Patrol agents time-consuming processing duties, allowing them to open space in holding facilities. A federal judge in Florida ordered an end to the quick releases.

Also last week, a 17-year-old Honduran boy traveling alone died in U.S. Health and Human Services Department custody.
