A 51-year-old man who was found shot to death last week in DeKalb County was trying to meet someone to buy a drone off the “LetGo” application, police said.

A witness told Channel 2 Action News he watched as a father of four died alone in his truck.

Sam Norman was found slumped in his pickup truck on Indian Manor Drive on March 3.

Police told Channel 2 they believe robbery was the motive for Norman’s death and they are investigating the LetGo app for leads.

The tragic death leads officials to remind people that any time you want to meet a stranger for the purpose of buying or selling something, meet in a public place.

Police are searching for two suspects after a man trying to purchase a drone on the app was found dead in his truck.
