The search for a missing Dallas teen is over.
Alejandra Gonzales, 15, was found by neighbors Tuesday morning and returned to her family, police said.
Prior to Tuesday, the girl was last seen Sept. 24 boarding a DART train in Plano.
The teen suffers from a diminished mental capacity, investigators said, and is more trusting of strangers. She has a fascination with trains and had been found on a train in the past.
