Investigators are trying to piece together what happened after a gun was reportedly fired during an argument at a motel in Santa Rosa. Witnesses at a Motel Six called police Sunday morning to report an escalating argument, the sound of gunfire, and a woman yelling “you just shot a gun at me.” Officers arrived to find a parked car with a bullet hole through the windshield, but found no shell casings. Officers also tried to speak with witnesses driving away from the area, but say they didn’t want to cooperate with the investigation.
