CHICAGO (CBS) — A developmentally disabled teenager who had been missing for more than a week has been found.

Police said 19-year-old Jessica DeShazer was found Wednesday morning, and taken to a hospital for treatment.

It was unclear where she was found, or exactly why she went missing.

Her mother, Ora DeShazer, said Jessica had a black eye, and had been assaulted.

She said she got a call around 2 a.m. Wednesday, from a caller asking her if there was a reward for Jessica’s return. She said she was afraid to go get her daughter at that hour, so she waited until the morning, and took community activist Andrew Holmes and K-9 specialist Robert Larson with her.

“She actually got a call this morning, with some people identifying where she was located,” said Tony Wallace, the victim’s uncle.

Her uncle says the teen left her home in the early hours of the morning to meet friends in a nearby park.

Jessica had gone missing nine days ago, and her parents feared she was being held against her will.

“Jessica is a happy-go-lucky child. She has a big smile, a big heart and she trusts everyone,” her mother said.

Relatives said the 19-year-old thinks like someone much younger.

“Anybody could manipulate her and say come on Jessica and she would just go,” said Jennifer DeShazer, Jessica’s aunt.

Jessica was at home near 93rd and Elizabeth streets in the Brainerd neighborhood when she vanished on July 8. Her mother said she had last seen her daughter just before 1 a.m.

“We were in my room. We were watching movies together,” her mother said.

At 3:30 her aunt saw her.

“The last time I had saw her I went to the bathroom and that’s when I saw her, she was, you know in her room on the phone,” said Jennifer DeShazer.

“I’m up about 6:30 quarter to 7 and I looked in her room. She wasn’t there,” said Ora DeShazer.
