The body of a Lawrenceville man who had been reported missing earlier this week was found in a truck early Wednesday morning, officials said.

Gwinnett County police responded to a report of a parked truck in the 200 block of Paden Cove Trail, according to spokesman Sgt. Collin Flynn. When they arrived at about 12:30 a.m., officers discovered Guadalupe Garcia Rodriguez, 40, in the vehicle.

Police have opened a homicide investigation.

Rodriguez’s wife had reported him missing Monday after he did not return home, officials said. He was last seen leaving in the truck that day.
