The fatal crash was reported at approximately 2:30 p.m. on Tuesday, March 17, 2026, on LA Highway 1085 near Alice Street in St. Tammany Parish. Louisiana State Police Troop L responded to the scene.
According to the LSP preliminary investigation, Cannatella was driving a 1999 Jeep Cherokee southbound on LA 1085 when a 2014 Nissan Murano, driven northbound by Williams, crossed the centerline and struck Cannatella’s Jeep head-on. Cannatella, who was not wearing a seatbelt, sustained serious injuries and was transported to a local hospital, where she later died. Williams, who was properly restrained, sustained moderate injuries and was also transported to a local hospital for treatment.
A passenger in Williams’ vehicle who was not wearing a seatbelt was also injured. That individual’s identity and condition have not been publicly released.
Williams showed signs of impairment at the time of the crash and was subsequently arrested, according to Louisiana State Police. Toxicology results are pending. Upon release from the hospital, Williams will be formally booked and charged with vehicular homicide, vehicular negligent injury, driving while intoxicated — third offense, careless operation, and possession of a fake motor vehicle inspection sticker. A third-offense DWI charge is considered a felony under Louisiana law, carrying a fine of $2,000 and up to five years in prison.
