A man shot four people to death at a family gathering in a Cuban neighborhood of Miami early Sunday, then went home and killed himself, police said. The man may have been upset because his wife had left him, according to a sergeant with the Miami Police Department's homicide division. Officers got a call shortly after midnight that numerous shots had been fired and a red pickup truck had been spotted leaving the scene. They arrived and found four bodies. Juan Sosa, who lives a block away, was out walking his dog early Sunday when he heard two shots and saw people running toward him, screaming. Then he heard as many as two dozen more shots and ducked behind a large tree to call police. "I didn't want to get hit," he said.
