Four people have died after a late-night crash on U.S. 61 in Mississippi’s Delta region.

The Mississippi Highway Patrol says two vehicles collided head-on near Valley Park in Issaquena County just before midnight on Saturday.

Troopers say that 39-year-old Jackson resident Thomas Williams Jr. was driving a Honda Accord southbound with 17-year-old Thomas K. Williams as a passenger. The car hit a northbound Nissan driven by 43-year-old Kamille H. Smith of Cleveland with 16-year-old Kirstin A. Lucas as a passenger.

Troopers did not state a cause for the wreck and are investigating.

Cleveland Central High School said on social media that Lucas was a student there, describing her as “genuinely kind, respectful, dependable, hardworking, intelligent, and most of all, a dear friend to so many.” Smith was her mother.

U.S. 61 around Valley Park is a two-lane road that mostly runs on an embankment above fields and wooded areas.
