Police are searching, in freezing temperatures, for a missing autistic teen in Ocala.

Friends of William "Billy" Snyder, 15, say the boy disappeared sometime Saturday night or Sunday morning from his group home. Workers and police have searched for him all day Sunday.

Snyder's parents, who live in Virginia, have been notified about the disappearance. Friends say the autistic teen has never walked away before.
