Authorities are searching by land and sea for an 8-year-old Autistic boy who went missing while vacationing in the Florida Panhandle.

Escambia County Sheriff's officials said Owen Elliot Black was on the beaches of Perdido Key with his mother and wandered off on his own and 4 p.m. Friday. He has brown hair and eyes and was last seen wearing a red and blue striped shirt and brown sweatpants.

Deputies and K-9 dogs trampled over sand dunes and searched in bushes, hoping Owen may be hiding because he was separated from his mother and was taught to avoid strangers.

The Pensacola News Journal reports 80 volunteers gathered to knock on doors and look in cars Saturday. Authorities also assembled teams of 10 to search sections of the beach.
