Mentally Disabled Glen Ellyn Woman Found Safe

UPDATE: 5 p.m. 9-23-14- Waller was located Monday night and is back with her family. She was unharmed.

(CBS) -- Police in Glen Ellyn are searching for a young woman who's mentally disabled and wandered away from home Sunday.

Nora Waller was last seen walking from her parent's Glen Ellyn around 10 a.m. Since then, police have posted her picture at the Metra station and various locations downtown.

Deputy police chief William Holmer says Nora Wallar looks like a normal 21-year-old but isn't.

"She has a form of autism that makes her unable to care for herself. She simply has a diminished mental capacity," he says.

Police are worried someone could exploit that, as happened when Nora wandered away from her school in Lombard in July.

"A man ended up picking her up and they found her together with this man later on."

Nora left with no ID, no phone and nothing but the clothes she was wearing: black yoga pants, a burgundy sweater and purple framed glasses.

Glen Ellyn police are asking anyone who sees her to contact them.
