Louisiana State Police vehicle, Friday, December 15, 2017, in Baton Rouge, La.

A 55-year-old Vacherie woman died after another driver crossed the center line on La. 18 and struck her car head-on Tuesday, State Police said.

Rickie Steib, 59, also of Vacherie, was driving his pickup east on La. 18 near Hubble Lane about 10 p.m. when he hit Marie Joseph's car, State Police spokesman Trooper First Class Jesse LaGrange said. Investigators do not know what prompted Steib to drive over the center line or whether impairment was a factor.

Steib, who was not wearing a seat belt, was hospitalized with moderate injuries. Joseph, who also wasn't wearing a seat belt, was hospitalized with critical injuries and later died.

The Louisiana State Police Crime Lab is processing a toxicology sample from Steib. The Jefferson Parish Coroner's Office is processing a standard toxicology report on Joseph.

Troopers continue to investigate.
