Investigators determined the boy discovered on a Portland MAX train last week was from Vancouver, Wash., and eventually made contact with his mother. The child remained in the custody of the Oregon Department of Human Services pending the outcome of its investigation.
Portland police said in a written statement that media coverage of the situation generated a large number of tips from Vancouver, including a friend of the mother who confirmed the youngster's identity. The statement also credited a 2011 training program sponsored by the Oregon Autism Society for helping patrol officers make contact with the boy and keep him calm while they got him off the train.
The child's name was not released nor was any information on how he wound up in Portland.
