(NewsNation) — Police in Amarillo, Texas, closed the case of a teenager who was reported missing in 2010 after she was found living on the East Coast.

In October of 2010, then 14-year-old Jessica Delgadillo was reported missing after she failed to return home from school. Police opened an investigation immediately but did not locate Delgadillo.

In 2023, the Amarillo Police Department established a cold case unit that began investigating three cases of missing children which remained unsolved, including Delgadillo’s.

The unit began working with the Center for Missing and Exploited Children and posting information about the case on social media in hopes of getting any information that could lead to answers.

In November 2023, the unit got a call from a woman who identified herself as Delgadillo and knew she had been reported missing. A DNA sample compared with DNA from a relative confirmed she was telling the truth.

Delgadillo requested that her location and the details of her disappearance not be disclosed. Police said the case is now considered closed.
