(CNN) Geovany Valle laid his 10-year-old daughter to rest in a town not far from where she grew up in the central region of El Salvador.

Darlyn Cristabel Cordova-Valle died in September in Nebraska after spending months in the custody of the Department of Health and Human Services, but her death was not announced until last week.

The young girl's concrete tomb is on a hill surrounded by trees, with a turquoise cross that bears her name and the date she was laid to rest in silver letters.

Her father was placing white and green paper flowers on the tomb the day CNN visited. He remembered the last time he saw his daughter alive: He was talking to her through video chat while she was in a hospital in Nebraska.

Darlyn was encountered by Border Patrol on March 1, 2018, a few miles west of Hidalgo, Texas. She complained of chest pain and three days later, was transferred to HHS custody where she remained for about seven months. Darlyn was treated for a congenital heart defect at various hospitals -- including in San Antonio, Texas and Phoenix, Arizona.
