Efforts continued Monday to locate the man who sexually assaulted a 7-year-old girl in the Upper Marlboro area, as police recruits searched for evidence, and officers planned to go to the area in the evening to hand out flyers.

The girl, who had been playing with friends, wandered away from them when she was accosted Saturday in the Marlton neighborhood by a man who brandished a gun, police said. The man assaulted her behind a building, then fled, police said.

They said they are looking for someone described as an older white man with a heavy build, who was bald and had a goatee-style gray beard.
