According to police, an 18-year-old and a 19-year-old were fatally shot in the head. Another victim of undetermined age was wounded in the torso. That person was taken to a hospital and later pronounced dead.

Police say another 18-year-old shot in the torso was taken to the hospital in critical condition. The fifth victim, 19, was reported in critical condition with wounds to the body.
