LeBEAU, La. —  A 46-year-old woman has been booked with murder in the death of her 90-year-old husband after she ran over him with their pickup following an argument, the St. Landry Parish Sheriff's Office said Monday.

Witnesses told investigators that Diana and Claude Bihm argued in the parking lot of Stelly's Grocery on Sunday and continued the fight while inside the store. As they left the store, Diana Bihm got into the truck's driver's seat while her husband walked away toward a car wash, the sheriff's office said.

"The female drove the vehicle to the edge of the concrete parking lot and stopped there briefly. The witnesses stated at that point, the female subject proceeded at a high rate of speed, hitting the male subject with the vehicle, knocking down a car wash concrete base vacuum cleaner and partially running over the subject with the front of the vehicle," Sheriff Bobby Guidroz said in a news release.

Claude Bihm later died from injuries he sustained after being struck, authorities said.

Bihm was booked with second-degree murder.
