Calgary police and 120 trained volunteers are searching for an 11-year-old non-verbal autistic boy missing since Thursday afternoon. Authorities are playing the child’s favorite Disney songs from patrol cars to help locate him.

Parker was last seen at a home in Calgary’s north end, wearing grey shorts, no shirt, and black noise-cancelling headphones. Police have ruled out foul play in his disappearance.
