A driver was killed Friday morning when his vehicle — traveling westbound on Interstate 10 at Slidell — left the road, crossed the median and entered the eastbound travel lanes, where it was struck by another vehicle, police said.

The crash, which occurred shortly after 9:30 a.m. near the state line, claimed the life of a 34-year-old man, according to a State Police news release. The man’s identity was being withheld pending notification of his family.

For reasons still under investigation, the man’s 2004 Mercedes-Benz exited the roadway, began to rotate and entered the eastbound travel lanes, police said. Jessica Sheffield, 22, of Auburndale, Fla., driving a 2014 Jeep eastbound on Interstate 10, drove her vehicle to the right shoulder in an attempt to avoid the collision.

Despite Sheffield’s efforts, the front of the Jeep crashed into the driver’s side door of the Mercedes, severely injuring the Mercedes’ driver. He was pronounced dead on scene by the St. Tammany Parish Coroner’s Office. Sheffield sustained moderate injuries in the crash and was transported to Oschner Medical Center Northshore.

Troopers do not suspect impairment as a factor, police said. As part of the on-going investigation, troopers obtained blood samples from both drivers to be sent to the Louisiana State Police Crime Lab for analysis.
