A man was found dead in a pickup truck Wednesday morning in the parking lot of a Walmart Neighborhood Market in Warner Robins.

Jennifer Parson with Warner Robins Police did confirm a body was found at the location on Russell Parkway and she said they believe the man has been in the car since Tuesday, but they’re not sure about his time of death.

Houston County Coroner Danny Galpin said the man died of natural causes and he’d have to do an autopsy to officially confirm the man’s cause of death.

The man’s name has not been released yet.
