The relationships and motivation for the shooting on the 5200 block of Venus Drive are still unclear, Fairfield police Officer Cleo Mayoral said. Police expect to release a more detailed timeline of events at the shooting, which appears to have started as a domestic dispute.
The fourth victim and 911 caller from the scene was treated and released Saturday from a local hospital after he suffered a gunshot wound to the ankle, Mayoral said.
The Solano County coroner's office has not released the names of the victims, Mayoral said.
