Chula Vista police think this man was involved in shooting at Main Street 7-Eleven.

 A man was recovering Monday from a gunshot wound he suffered over the weekend during a late-night scuffle at a South Bay convenience store.

Patrol officers responding to reports of a shooting outside the 7- Eleven in the 4300 block of Main Street in Chula Vista shortly after 11:30 p.m. Sunday found John Oelke, 55, suffering from a gunshot wound to his left arm.

Detectives determined that Oelke and another patron had gotten into an argument over food inside the market, Lt. Dan Peak said. When Oelke left the business, the unidentified man followed him, according to the lieutenant.

“While in the parking lot, the (assailant) pulled out a gun and pointed it at the victim,” Peak said. “The victim and the (other man) then struggled over the gun. During the struggle the gun went off, and the victim was shot in the arm.”

Paramedics took Oelke to a hospital for treatment of the apparently non-life-threatening injury.

The shooter is thought to have fled from the scene on a motorized black bicycle or scooter and was not located, said Lt. Dan Peak of Chula Vista police. The offender is described as a Hispanic male adult in his 30s, about 5-feet-4 or 5-feet-5, thin build and wearing a helmet with a light on.
