Briggs Chaney sniper strikes 3 times with pellet gun, still at-large (Video+Photos)

Four people have been hit by "projectiles" from a "pellet gun"-wielding sniper in the Briggs Chaney area of Silver Spring since January 23, according to Montgomery County police. Detectives have obtained surveillance footage of a suspect they believe was the shooter in one of the incidents, and are seeking the public's help to identify and locate him.

The alleged sniper's first victim was in the 3050 block of Briggs Chaney Road on January 23. Police have not said what time of day that first shooting occurred. Detectives said they have reason to believe the additional shootings were related to that one.

On Monday, January 29, at an unspecified time, police responded to the 14100 block of Aldora Circle. An adult male told officers he was struck by "pellets" while standing outside of his home. Six minutes later, 911 received a call from the 13800 block of Outlet Drive. Two adult females there reported they, too, had been struck by "pellets."

Surveillance video from a business on Outlet Drive showed a person police believe is the shooting suspect in the January 29 incidents. The suspect entered that business before shooting the projectiles at the victims on Outlet Drive, detectives said. In the video, the suspect can be seen wielding a gun, and wearing a light-gray hoodie.
