Washington (CNN)A 10-year-old Salvadoran girl who died in Department of Health and Human Services custody last September was identified Friday by a US Customs and Border Protection official as Darlyn Cristabel Cordova-Valle.

On Thursday, HHS spokesman Mark Weber had announced the girl's death but did not provide her name.

After she was apprehended nine miles west of Hidalgo, Texas, in March 2018, Cordova-Valle spent about 45 hours in CBP custody before being transported to the custody of HHS's Office of Refugee Resettlement.

In a statement Thursday, Weber said the 10-year-old girl had a history of congenital heart defects. He said the child had surgery complications that had left her in a comatose state. She was transported to a nursing facility in Phoenix and later transported to Children's Hospital in Omaha, Nebraska, where she died due to fever and respiratory distress on September 29, according to Weber.
