SOUTH WINDSOR (AP) — A shooter opened fire and wounded two people outside a Connecticut business Tuesday and was taken into custody at gunpoint on a highway in Massachusetts, police said. Both victims were treated at a hospital and discharged.

Authorities identified the alleged gunman late Tuesday afternoon as Alan Rosario, 33, of Springfield, Mass. It was not immediately clear if he has a lawyer who could respond to the allegations.

One of the victims called 911 at about 8:45 a.m. to report a shooting in the parking lot of a South Windsor industrial building housing several businesses, police Sgt. Mark Cleverdon said.

The shooting stemmed from an argument between two employees, one of whom was the shooter, of a trucking logistics company, Cleverdon said. The nature of the dispute wasn't clear. The targeted victim had gunshot wounds to his leg and arm, while another man appeared to have been hit by shrapnel from the shooting of the first victim, he said.

“It was an isolated dispute between them,” Cleverdon said at a news conference. “It sounds like there was a verbal argument before the weapon got pulled and then the shooting happened and then he left the scene.”

The shooter fled. Police broadcast a description of the vehicle to other law enforcement agencies. Enfield officers spotted the vehicle on Interstate 91 and followed it into Longmeadow, Mass., where officers pulled pulled it over and were immediately joined by Massachusetts state troopers, police said.

Massachusetts State Police identified the suspect as Rosario and said officers removed him from the vehicle at gunpoint. A handgun was found in the car, officials said.

Rosario was detained by Massachusetts State Police in Springfield and faces extradition proceedings to send him back to Connecticut. South Windsor police were deciding what charges to file.
