Montgomery County detectives are looking for a 15-year-old boy missing since Nov. 17.

Miguel Williams, 15, was last seen at the intersection of Layhill Road and Georgia Avenue, near the Glenmont Metro station in Silver Spring, at approximately 3:30 p.m.

Williams had been staying at the 17700 block of Norwood Road in Sandy Spring, but authorities suspect he may be headed to Upper Marlboro, where his family lives, according to a Montgomery County police spokeswoman.

Authorities and his family are concerned for Williams' welfare -- he's not been seen or heard from since Nov. 17, though officials don't suspect any suspicious circumstances surrounding his disappearance, according to a spokeswoman.

Police described Williams as a black male, 5 feet 4 inches tall, weighing 120 pounds. He has brown eyes and short brown hair. Williams has two small scars on the bridge of his nose and a distinguishing scar on his left ear.

Anyone with information about Williams' whereabouts is asked to call Montgomery County's family crimes division at 240-773-5400. Callers may remain anonymous.
