Authorities are searching for a third suspect in connection with a fatal shooting at a Duluth-area gas station.

Gwinnett County police announced Thursday that 19-year-old Jaime Manuel Jimenez is wanted on charges of felony murder and aggravated assault in the Feb. 5 death of 20-year-old Jamun El Winslow.

The Lawrenceville man was found dead in a car near the Grande Club Apartments on Club Drive, not far from a Shell station on Pleasant Hill Road. Investigators believe he was shot at the gas station about 10 p.m., drove away and crashed, AJC.com previously reported.

In court on Friday, a Gwinnett detective testified that a witness was able to identify Najarro by the “Loyalty” tattoo she has on the side of her face, Channel 2 Action News reported.

Investigators also revealed that robbery was likely the motive in the fatal shooting.

“Ultimately, it appears as though it was possibly a robbery and that they were all involved with it,” Detective Doug Loomis said.

Police said Villafana-Diaz was in the car with Winslow when Jimenez walked up and shot him, Channel 2 reported. As Winslow tried to drive away, she allegedly jumped out of the moving car.

Investigators said in court they believe drugs were involved.
