State police are investigating a fatal crash on Interstate 20 about 10 miles west of Ruston.
Sunday's accident claimed the life of a Shreveport woman.
Troopers say a car driven by 19-year-old Sylesia Howard was traveling west on I-20 in the left lane when an unknown vehicle that was traveling west in the right lane swerved into the path of her car. Howard's car ran off the road and struck a tree.
Troopers say the unknown vehicle continued traveling west and did not stop.
Howard was pronounced dead at the scene by the Lincoln Parish Coroner's office.
