The initial investigation led Troopers to determine that the crash occurred as Chaignaud was driving a Toyota Camry westbound on Interstate 12 in the right lane. For reasons still under investigation, Chaignaud’s vehicle drifted onto the right shoulder and struck an unoccupied Nissan Pathfinder. Chaignaud’s vehicle veered back onto Interstate 12 and was struck by a Freightliner Tractor-Trailer traveling westbound in the right lane. Chaignaud sustained fatal injuries and was pronounced deceased on the scene. The driver of the Tractor-Trailer received minor injuries and was transported to an area hospital.
As part of the ongoing investigation, blood samples were collected for scientific analysis. Both drivers were properly restrained. The investigation is ongoing and no additional information is available at this time.
