Police in Miami say a man shot four people to death at a family gathering, then went home and killed himself. A sergeant with the Miami Police Department's homicide division said police learned of the shootings early Sunday. They apparently stemmed from a domestic dispute. The names of the victims and gunman aren't being released because family members haven't been notified. Police said the gunman may have been angry because his wife had left him, but continue to investigate. The house where he killed himself is about three miles from the house where the shootings occurred.
