When units arrived, Marvin Cuevas, 57, was pinned under his 1991 Nissan Pathfinder, Hargrove said. Not wearing his seatbelt, Cuevas died as a result of head, chest and neck injuries.
Sheriff deputies responded the accident at 4:55 a.m.
Cuevas apparently was going too fast to negotiate a sharp left curve on Herman Ladner Road, which is north of Mississippi 53.
A toxicology report, which is standard proceedure, is pending.
