BALTIMORE (AP) — Police are searching for clues after two people were killed and four others were injured when shots rang out in front of a northwest Baltimore store.

Police say that a gunman fired on the people about 6 p.m. Wednesday. The suspect has not been found.

One man was pronounced dead at the scene and a second was pronounced dead at a hospital. Police say a third man was critically wounded, and a fourth man and two women had injuries that were not life-threatening.

On Thursday, police identified the dead men as 23-year-old Davon Dozier and 29-year-old Troy Smothers.

Police say detectives and an academy class were combing the area Thursday for additional evidence.

Police believe the shooting was in retaliation for a homicide several days ago.
