Authorities say a young woman critically injured in a car wreck in Copiah County remains in critical condition at University of Mississippi Medical Center this morning.

Sonya Jackson, an 11th grade student at Wesson High School, was airlifted to UMMC Tuesday afternoon some time after 4 p.m.

Olivia Grubbs, also an 11th-grader, and Tabitha Manning, a 10th-grader, were also taken to UMMC with injuries.

Capt. Joey Errington with the Copiah County Sheriff’s Department said the one-car crash occurred shortly before 3:30 p.m. on Beauregard Road about a half mile from Monticello Road. He said Jackson was a passenger in the 2016 Hyundai Essex driven by Grubbs. Manning was in the passenger seat while Jackson was in the back seat alone, he said.

Errington said it appears that Grubbs was traveling east when she lost control and the car left the road and jumped a fence. He said deputies arriving at 4 p.m. found the car on its rooftop.

It’s not known what caused the crash at this time, he said, and the incident remains under investigation.

Jackson’s uncle, Howard Shawn McClendon, 42, was killed in an unrelated crash Thursday morning on I-55 about a half mile north of the Lincoln County line in Copiah County, Cpl. Eric Henry with the Mississippi Highway Patrol said.

“It’s a sad day for that family,” Copiah County Sheriff Harold Jones said.
