Authorities are trying to locate two vehicles believed to be involved in the sniper shootings. They include a white box truck matching composite images and a white Chevy van.
Police said the composite came from several witnesses at different shooting scenes.
Montgomery County police have also set up a special post office box to receive tips from the community. Chief Moose said police have been flooded with mail since the sniper shootings began.
