The occupants of two cars driving on 41st Street near Parrish were shooting at each other around 8:40 p.m. and the victims were caught in the crossfire, said Lt. John Walker of the Southwest Detective Division.

An 81-year-old man was shot in his head, "He may not survive, he's in very critical condition," said Chief Inspector Scott Small.
