A suspected gunman was arrested Wednesday morning for his involvement in a fatal shooting at a Norcross mechanic shop, police said.

Francisco Javier Alvarenga-Molina is facing several charges, including felony murder, possession of a firearm during the commission of a crime and possession of a firearm by a felon. He was booked into the Gwinnett County Jail early Wednesday after being arrested during a traffic stop, Norcross police spokesman Capt. Robert Braud confirmed.

Officers were called to the mechanic shop on Lively Avenue, right off Buford Highway, regarding a shooting at 3:45 p.m. Tuesday. A man was found dead at the scene, along with another man who witnessed the incident, Braud said. The accused shooter, later identified as Alvarenga-Molina, had already left the location.

According to Braud, the three men knew each other and went to the shop together in hopes of selling some tools. While outside the shop, the gunshot victim and Alvarenga-Molina got into an argument that eventually turned physical, officials confirmed.

“The male suspect went back to the car, grabbed a shotgun, shot the victim one time,” Braud said, adding that Alvarenga-Molina left the gun at the scene before fleeing.

The victim was not publicly identified.

None of the employees or customers saw the incident, but authorities stated that multiple people heard the gunshot. The witness was not detained and Braud said he does not expect that person to be charged.

Alvarenga-Molina was also booked on charges of theft by receiving stolen property, possession of a controlled substance, possession of methamphetamine, identity theft, card theft, driving without a valid license and unsafe lane change. He remains in jail without bond.
