IN BRIEF: A second suspect wanted for the armed robberies of the Subway and Elliott's Market convenience store on Sigman Road turned himself in on Monday.

Derek Quantrell Cummings, 19, of Conyers came to the Conyers Police Department with his attorney David LaMalva on Monday, said CPD Lt. Jack Dunn.

Dunn said he had been in contact with Cummings' mother but did not know the 19-year-old would be turning himself in.

"We do plan on following up with other appropriate charges," said Dunn, such as posession of a firearm during the commission of a crime.

Cummings was wanted for the June 8 armed robbery of the newly built Subway on Sigman Road.

Another suspect in that robbery, Antwain Ervin Boglin, 20, had already been in jail on a separate charge when police began questioning Boglin after information was received from the public.

CPD also suspect a third person was involved in the Subway robbery.

Cummings was also wanted for the June 11 armed robbery of the Elliott's Market gas station convenience store on Sigman Road and Rockbridge Road, which is under investigation by the Rockdale County Sheriff's Office.

In that incident, after the robbery, two suspects were seen running out of the woods towards a car that was parked near Irwin Bridge Road. An officer checking out the car saw the suspects but they escaped on foot back into the woods.

According to RCSO investigator Michael Camp, the car was registered to Cummings, and investigators also identified items that belong to Cummings in the car.

"We're still looking for our second man" in the Elliott's Marketplace robbery, said Camp.
