The mother of the 10-year-old girl from El Salvador who died in federal custody last year says the girl was born with a heart murmur, according to CNN.
The mother, who does not want her identity revealed, says doctors told her that her daughter, Darlyn Cristabel Cordova-Valle, would need heart surgery.
Border Patrol found Darlyn near the U.S. Border in March of 2018. The girl had traveled with acquaintances from El Salvador with the hopes of reuniting with her mother.
But according to a health and human services spokesperson, Darlyn was sent to a hospital with chest pains.
She was transported to various facilities for treatment, including San Antonio, Phoenix and Omaha.
Darlyn’s mother says authorities would not give her custody of her daughter.
The girl died in September due to fever and respiratory distress, but Darlyn’s death was not announced until Thursday.
Hers is one of six recent deaths of migrant children while in custody of federal authorities after journeying to the U.S.
