GWINNETT COUNTY, Ga -- A serial robber isn't making it hard for police to tie all of his robberies together. So far police believe the suspect has robbed seven gas stations or drug stores since December 10, 2013.

Five different police agencies have tied the cases together from surveillance video and descriptions from victims and witnesses in the seven robberies.

He walks into the stores and demands money from the clerk and then walks out with only a handful of cash. Police said he is rarely violent. In one robbery he knocked over a display case when the clerk didn't comply with his demands.

Because he doesn't get much money and he has hit so many times police believe he may be a drug user. "We find a lot of times that when people are committing crimes just to support a habit, they're not concerned about a whole lot but their next fix," said Cpl. Jake Smith of the Gwinnett County PoliceDepartment.

The robbing spree started on December 10, 2013 at a Sam's Mart gas station on Highway 78 in Gwinnett County. He robbed a Rite Aid pharmacy in Sugar Hill on December 29th.

Sandy Springs police say he is wanted for a robbery there on January 1, 2014. Roswell policesaid he robbed a CVS on January 5, 2014. Cobb policewant him for two robberies and DeKalb policewant him for one.

Police said he doesn't seem to care if he's caught because he wears the exact same outfit in every robbery. He wears a baseball cap with either a Detroit Tigers logo or a Boston Red Sox logo. He also wears a distinctive Air Jordan sweatshirt with a bright red and white log. "Wearing the same clothes is unusual when it's not a disguise," Cpl. Smith said.

The suspect is believed to be driving a 2004 Hyundai Elantra hatchback.

Smith said police have tied him to seven robberies so far, but there could be more that other police agencies are investigating that haven't been tied to this case yet.

Anyone with information about the robberies is asked to call Crime Stoppers Atlantaat 404-577-TIPS (8477).
