The 8-year-old girl who died in U.S. Border Patrol custody in Texas was seen by medical staff numerous times and had a fever that topped out at nearly 105 degrees, but officials still denied her family’s requests for an ambulance, an internal investigation has found.

The girl, Anadith Tanay Reyes Alvarez, died last month after what U.S. Customs and Border Protection described as a “medical emergency.” Anadith, who was from Panama, was traveling with her family and was in custody at Harlingen Station in the Rio Grande Valley, minutes from the border with Mexico.

The agency said Thursday that its Office of Professional Responsibility is continuing an internal investigation into Anadith’s death on May 17, and has found failures to document medical encounters and refusals to review her records or take the child for higher-level care.

“They killed my daughter, because she was nearly a day and a half without being able to breathe,” Anadith’s mother, Mabel Alvarez Benedicks, told the Associated Press after her daughter’s death. “She cried and begged for her life and they ignored her. They didn’t do anything for her.”

Investigation: Girl was treated 9 times in 3 days

Anadith, her two siblings and her parents crossed the border into Texas on May 9, according to her mother. They were transferred to Harlingen Station the evening of May 14. CBP found that between the evening of May 14 and morning of May 17, Anadith was seen by medical staff nine times.

She had a fever, flu-like symptoms and pain, a statement from the agency says. Anadith also was struggling to breathe and couldn’t walk, her mother told the Associated Press after she died.

Her fever peaked at 104.9 degrees on May 16, CBP said.
