A 54-year-old motorcyclist from Scott was killed Thursday night in a crash that occurred when a motorist turned in front of him on La. 343 in Acadia Parish, State Police said.

Emile J. Sonnier was pronounced dead at a hospital after the 10:30 p.m. accident, Master Trooper Brooks David said.

Sonnier was riding a 2007 Harley Davidson south on La. 343, south of La. 98 in Acadia Parish, when a northbound 2002 Mitsubishi Montero driven by Theresa A. Guidry turned left in front of him. Sonnier struck the rear of Guidry’s car, causing the rider and his motorcycle to roll left, veer off the road and hit a ditch, David said.

Guidry, 57, of Scott, was cited for making an improper turn. David said impairment is not suspected.

The case remains under investigation.
