FRESNO (AP) – A gunbattle Tuesday at a central California home left three men dead and another wounded in what may have been a home-invasion robbery or a drug deal gone bad, police said.

Two men drove up to the house in a Fresno neighborhood, and at least one of them went inside, where he held a man in his 50s at gunpoint, Fresno Lt. Mark Hudson said.

Another man inside the home, possibly the older man’s son, came out of a bedroom and opened fire with an assault rifle, Hudson said. The assailants were armed with a handgun, and an ensuing shootout spilled outside the house.

“At this point, we’re still investigating,” Hudson said. “We’re really in a preliminary stage of the investigation.”

Police who arrived found one attacker inside a vehicle and another outside and the two other men in the home. All four had gunshot wounds.

The assailants and the older man held at gunpoint died, Hudson said. The fourth man’s wounds were not considered life-threatening.

The violence comes nearly two months after authorities say a racially motivated attack in Fresno killed three white men targeted at random. Prosecutors also have charged Kori Ali Muhammad, who’s black, with fatally shooting a fourth white man, an unarmed security guard at a motel, a week earlier.
