One person was killed in a triple shooting outside a Walmart off Cascade Road, Fulton County police said.

Someone heard gunshots and flagged down a police officer just before 11 p.m. Sunday, Channel 2 Action News reported.

When officers got to the parking lot of the Walmart in the 1100 block of Research Center Drive, they found two men with gunshot wounds. Both were taken to Grady Memorial Hospital, and one of the men died en route to the hospital, Fulton police Cpl. Maureen Smith said.
