Raleigh, N.C. — A Raleigh convenience store manager who was shot to death last week was laid to rest Monday in Roxboro at Blue Wing Baptist Church, where she was a member.

Family members say Stephanie Powell Anderson, was opening the Trade Wilco convenience store on Trawick Road Thursday at about 4:30 a.m. Thirty minutes later, her boyfriend found her dead behind the counter. She had been shot.

Sources tell WRAL it might have been a botched robbery, but police have declined to provide further details about the investigation and did not expect to release any new information Monday.

Last week and over the weekend, investigators set up traffic checkpoints near the store in an effort to generate leads.

"The investigation is making progress," Raleigh police spokesman Jim Sughrue said. "Right now, what we need more than anything else is assistance from the public.

Anyone with information about Anderson’s shooting is asked to call the Raleigh Police Department’s Detective Division at 919-890-3555 or Crime Stoppers at 919-226-CRIME.

Authorities are also working to determine if Anderson's death is connected to any other unsolved robberies in the area.

More than 170 robberies were reported in the first two months of this year – a 50 percent increase from the same time last year.
