A Taco Bell manager fought with an employee at work before following him to a Scott Township business and fatally shooting him Wednesday afternoon, police said.

Police responded to the Northwestern Mutual Life Insurance office at Cochran and Greentree roads in Scott Township at
12:07 p.m. after receiving reports of shots being fired, Allegheny County Police Superintendent Chris Kearns said.

Responding officers found a man in the office foyer who had been shot to death. The Allegheny County Medical Examiner’s Office late Wednesday identified the victim as Dorian Carver, 32, of the Natrona Heights section of Harrison.

Police identified the suspect as Zairyre Simmons, 23, of Pittsburgh.

Investigators said the men had a dispute on Cochran Road, and Simmons followed Carver into the Northwestern Mutual
office and shot him, Kearns told the
Tribune-Review. The suspect ran from the office after the shooting.

County police Lt. Vernando Costa said the incident started at a nearby Taco Bell. Both men worked at the fast-food restaurant, police said in a criminal complaint.

Police said Simmons was Carver’s supervisor. They had gotten into a dispute over a workplace reprimand and had to be separated before the shooting, according to a criminal complaint.

Police said the gun used in the shooting was stolen Oct. 6 from someone in Pittsburgh.

“Once separated, Dorian Carver ran out of the restaurant toward the Northwest Mutual building. Zairyre Simmons ran into the employee-only area, grabbing his coat, and ran after Dorian Carver,” police wrote in a criminal complaint. “Detectives viewed the Taco Bell (surveillance) video confirming the altercation and that Dorian Carver fled the restaurant. The video also showed Simmons leaving in pursuit of Carver.”

During a search of the shooting scene, an officer found a semiautomatic handgun behind a vacant building next to Northwestern Mutual, the complaint said.

Simmons turned himself in to police about 7:45 p.m. He did not have a permit to carry a concealed weapon, police said.

Large sections of Cochran and Greentree roads were closed to traffic as police investigated and combed the area for the suspect. The heavy police presence included officers from numerous nearby departments, county police and SWAT teams in armored vehicles.
