Jun 24, 2014 20:34 State Police: Alcohol, drug use suspected in West Feliciana crash State Police: Alcohol, drug use suspected in West Feliciana crash Advocate staff report June 24, 2014 Comments A 66-year-old St. Francisville man was airlifted to a Baton Rouge hospital Saturday night, a State Police trooper said, after he caused a two-vehicle crash on La. 969, just south of the Louisiana-Mississippi border in West Feliciana Parish. Raoul Cavalier, 66, was driving north on La. 969, a narrow two-lane highway, in a Chevrolet pickup when the truck crossed the center line into oncoming traffic, striking a Dodge pickup carrying two adult passengers, said Master Trooper Greg Marchand, a State Police spokesman. The impact from the crash dislodged the driver’s-side door and front left tire of Cavalier’s pickup, Marchand said. Troopers suspect alcohol and drug use by Cavalier factored into the crash, Marchand said. Cavalier, who remains in serious condition, and the two people in the Dodge pickup, Alan Perry, 34, of St. Francisville, and Lacie Deville, 25, of Denham Springs, were all wearing seat belts at the time of the crash, Marchand said. Perry and Deville refused medical aid after the crash, Marchand said. Troopers collected routine samples so crime lab analysts can conduct toxicological tests. Those results and criminal charges against Cavalier are pending as the crash remains under investigation, Marchand said.
