UPDATE: Londin Marshall has been located safe and sound in a neighbor's apartment.
Montgomery County police are asking for your help in finding a missing girl.
Detectives said Londin Marshall, 8, got in an argument with her family and left their apartment on Blair Mill Road in Silver Spring about 4:30 p.m. Monday.
Police say the girl had on a gray button down sweater, faded black jeans and gray suede boots when she left home.
Her family says Marshall knows how to get around on the Metro rail system, so she could be anywhere. Police say she may be scared to return home because she did not have permission to leave.
Her family and police fear for her safety because of her age and the cold temperatures.
