A passenger killed early Sunday in a one-vehicle crash on North Acadian Thruway had suffered stab wounds in an altercation and was being driven to a hospital, Baton Rouge police said Monday.

Cpl. L'Jean McKneely, BRPD spokesman, said Tomeka Jacobs, 36, had apparently been stabbed in some sort of altercation in the 4100 block of Levera Street, which was why she was being driven to a hospital. McKneely had no further information on the severity of the stabbing.

BRPD spokesman Cpl. Don Coppola said both the stabbing and the crash are still being investigated.

A 37-year-old, who was not identified, was driving a 1996 Ford Explorer when it went off the road and flipped at about 4:40 a.m., McKneely said. Jacobs, 36, who was in the passenger seat and not wearing a seat belt, was thrown from the SUV and landed underneath the vehicle, he said.

Jacobs, of 5710 Benson Drive, Baton Rouge, died at the scene, McKneely said. The driver was taken to a hospital for non life-threatening injuries.

Police suspect alcohol and drugs to be factors in the wreck, McKneely said.
