(KUTV) — The man accused of killing a man in Murray Wednesday said they had been arguing over a vehicle before the shooting. Patrick Brown, 42, was arrested for murder, three counts of aggravated assault, four counts of felony discharge of a firearm, and possession of a dangerous weapon, according to a probable cause affidavit. Officers responded to 4500 S. Main St. in the early afternoon hours Wednesday after shots were fired. When they arrived, they found 39-year-old Darnell Brown on the ground next to a vehicle. He suffered multiple gunshot wounds and was treated by paramedics before he died. Several people, who had been inside the victim's vehicle when the shooting occurred, helped police identify Patrick Brown as the gunman and described his vehicle, the affidavit states. Officers tracked down Patrick Brown's vehicle and obtained a search warrant for his home. "The suspect surrendered during police callouts and made a spontaneous statement that he was going to call the police and turn himself in. He also told officers that he shot the victim and the firearm was inside his residence," the affidavit states. During an interview with police, Patrick Brown said he had been arguing with Darnell Brown about a vehicle. They followed each other in separate vehicles out of a local apartment complex to 4500 S. State St., where a collision occurred between the two cars. "Patrick stated that the victim then reversed and separated himself. Patrick said he turned around and drove towards the victim's vehicle," the affidavit states. Patrick then drove past the victim's car and allegedly discharged his gun, striking and killing the victim. A video captured on a cellphone, later turned in to police by a witness, confirmed the sequence of events, officers reported. Patrick Brown is a restricted person under Utah law and is not legally allowed to carry a gun, according to court records. The arrest report did not disclose if the victim and suspect are related.
