The search for a Massachusetts teenager who went missing while skiing at Maine’s Sugarloaf mountain is continuing. The resort’s ski patrol and law enforcement personnel are scheduled to resume looking for 17-year-old Nicholas Joy of Medford, Mass., on Tuesday. Joy was reported missing Sunday afternoon after failing to meet with his father. Authorities say Joy and his father split up and took separate trails from the top on Sunday, and the father called for help when his son later failed to meet with him. The Sugarloaf ski patrol, game wardens and others searched in-bounds and out-of-bounds areas on skis, snowshoes and snowmobiles late Sunday afternoon and again on Monday, without finding any sign of the boy.
