BALTIMORE (AP) — Police say six people have been shot, two fatally, in front of a northwest Baltimore store.

Spokesman T.J. Smith said at a news conference near the Stop 1 Convenience Store in the Windsor Hills neighborhood that a lone gunman fired on people standing in front of the store at about 6 p.m. Wednesday.

Smith says one man was pronounced dead at the scene; a second was pronounced dead at a hospital. Police say a third man was critically wounded, and a fourth man and two women had non-life-threatening injuries.

Smith says detectives believe the shooting was retaliation for a homicide in the area several days ago.

Police said the shooter fled on foot. Smith says officers have a limited description of the suspect and urged witnesses to come forward.
