(CNN) -- A gunman fatally shot four women and wounded three others in a metropolitan Miami restaurant Sunday night, before turning the gun on himself, police said.
Mark Overton, the police chief of Hialeah -- where the shooting took place -- said the incident most likely stemmed from a domestic dispute.
The shooter first argued with a woman he was in a relationship with in the parking lot of Yoyito restaurant. Then he went into a restaurant where he confronted another person he knew and began shooting, Overton said.
A total of seven women were shot. Four died, one sustained life-threatening injuries and the other two were in critical condition, police said.
Overton said the suspect knew some of the victims, but "some may have been in the wrong place at the wrong time."
The shooter left the scene in a car belonging to one of the victims and was later found dead of a self-inflicted gunshot wound, police said.
