A Washington state man was shot and killed by a neighbor after allegedly opening fire on two adult female relatives during a domestic dispute that spilled into a nearby driveway, police said. Officers with the Puyallup Police Department responded around 9:10 a.m. on April 2, and investigators allege 47-year-old Arnino Guanlao fired on his adult relatives after a family argument escalated outside the home. A neighbor who had been inside at the time stepped outside and fatally shot Guanlao to intervene, according to police.
One of the victims, 23-year-old Christiannel Lyle Macapagal Maningat, died at the scene. The second woman was transported to a local hospital with life-threatening injuries, authorities said. The case remains under investigation, including a review of the neighbor’s use of force.
Washington law allows a person to use force to protect themselves or others if they reasonably believe it is necessary, but deadly force is justified only when facing an immediate threat of serious injury or death. Puyallup Police Department Captain Kevin Gill said during a press briefing that investigators are still determining exactly how the circumstances unfolded.
Witnesses described a chaotic scene as gunfire erupted in the neighborhood. A neighbor told reporters there was a girl who was found with a gunshot wound after responders arrived, and others said the community is in shock.
Investigators said the neighbor who shot Guanlao is cooperating as detectives work to determine the circumstances surrounding the use of force. Detectives are processing multiple scenes tied to the incident, and residents reported hearing multiple gunshots. Additional reporting by Law&Crime identified Guanlao as the victims’ stepfather and said he had been firing at his adult stepdaughters when the neighbor intervened. Authorities have not said what sparked the initial dispute.
