The Florida Highway Patrol is investigating after a body was discovered Saturday morning at the Interstate-10 westbound rest area in Santa Rosa County. FHP spokesman Lieutenant Eddie Elmore said troopers arrived at the scene at mile marker 30 at about 10:30 a.m. after they were requested to check on a tractor-trailer. They entered the tractor cab and found the body of a man who was pronounced dead at the scene. Elmore said troopers do not suspect foul play and the investigation is ongoing.
