REDWOOD – A Hermanville man died Monday morning when the log truck he was driving left Mississippi 3 and hit a Yazoo Valley Electric Power Association substation just south of International Paper Company’s mill.

Killed was Henry David Truitt, 59, of 1008 Stamps Drive. He was alone in the truck.

Warren County Coroner John Thomason said an autopsy has been scheduled at Mississippi Mortuary Service in Pearl to determine Truitt died before his truck crashed into the power plant at 10:53 a.m.

&#8220I scheduled an autopsy for tonight to find out if he suffered a heart attack after leaving the road or as a result of leaving the road,” Thomason said.

Trooper John Minor of the Mississippi Highway Safety Patrol said the 18-wheeler Truitt was driving south on Mississippi 3 &#8220lost control, went off the west side of the highway, came into the Yazoo Valley Electric Power Association plant and collided with a power station.

The Mack truck Truitt was driving is owned by Jeff Segrest of Port Gibson, Thomason said. Truitt deposited a load of wood at International Paper just minutes before the crash.

&#8220And 10 minutes later, his Mack truck left the highway, hit a road embankment, became airborne, landed and then crashed into (the) substation, which was inactive,” Thomason said. &#8220We have no reason to believe it was mechanical failure.”

Segrest could not be reached for comment.

Truitt was the 12th person to perish in a vehicle accident in Warren County in 2005.

The most recent previous fatal accident was Oct. 7 when Crystal Merritt, died in a crash at U.S. 61 North and North Washington Street. She was 21.

Funeral arrangements for Truitt had not been announced.
