UPDATE: A 25-year-old Zachary woman was killed Sunday evening in a single-vehicle crash on La. 64 at Hubbs Road east of Joor Road, State Police said in a news release Monday.

State Police gave this account of the crash:

Carrie T. Lipscomb was driving northbound on La. 64 around 7:15 p.m. when her 2009 Nissan Maxima left the road, entered a ditch and struck a culvert and tree stump, causing the vehicle to roll over. Lipscomb, who was unrestrained, was ejected from the vehicle and suffered fatal injuries.

She was pronounced dead at the scene by the East Baton Rouge Parish Coroner's Office. Police said impairment is not suspected, but a toxicology sample was taken and submitted to the State Police Crime Lab for analysis.

Earlier, preliminary reports of a second fatal crash on La 37 were incorrect.
