DeKalb County police have made an arrest in the death of Sam Norman, a father of four killed while making a purchase with the LetGo app.

But Shiera Campbell, a police department spokeswoman, declined to confirm the name of the suspect. She said the decision to withhold it for now is because investigators are looking into other cases possibly involving the suspect.

Norman, 51, was found slumped over in his pickup truck on Indian Manor Drive on March 3. He was trying to buy a drone, according to police.

He was shot, and a man was seen fleeing with a gun in hand, according to a police report.

Police told Channel 2 Action News last week they were combing the LetGo app, which connects people wanting to buy and sell goods, for leads.
