Shortly after 8:00 pm on May 8, 2016, Troopers from Louisiana State Police Troop A began investigating a fatal crash involving a pedestrian on LA 1 south of LA 75 in Iberville Parish.  The crash took the life of 51 year old John Williams of Plaquemine, LA.

The initial investigation by State Police revealed that the crash occurred as 31 year old Joseph Tatney of Plaquemine, LA was traveling southbound on LA 1 in 2001 Dodge Ram.  At the same time, Williams was walking across the southbound lanes of LA 1.  Williams was struck by Tatney’s vehicle causing him to come to rest in the inside lane of LA 1 southbound.  Williams’ was then struck by second vehicle that was traveling behind Tatney’s vehicle.  The second vehicle was a 2012 Chevrolet Camaro driven by 41 year old Ashley Mosby of Plaquemine, LA.

Williams sustained fatal injuries in the crash and was pronounced deceased at the scene by the Iberville Parish Coroner’s Office.  Tatney and Mosby were both properly restrained and were not injured.  Impairment is suspected to be a factor in this crash and atoxicology sample was taken from all parties involved for analysis.

Troopers did determine that Tatney was impaired at the time of the crash.  He was placed under arrest and booked into the Iberville Parish Jail for Vehicular Homicide.

Louisiana State Troopers wish to remind motorists that impaired driving continues to be a major problem throughout Louisiana. Whether impaired through alcohol, drugs, or a combination of the two, the consequences of driving while impaired remain the same.  Making good choices while in motor vehicles such as never driving while impaired, always ensuring every occupant is properly restrained, and avoiding all distractions can often mean the difference between life and death.
