WRIGHT CITY, Mo. — The son of a former Butler High School basketball coach was killed in a crash near St. Louis.

Mark W. Jula, 29, of St. Louis was driving eastbound on Interstate 70 at about 10 p.m. Wednesday when he ran off the right side of the road and collided with the rear of a tractor-trailer attempting to merge onto the road, according to a Missouri State Highway Patrol report.

A Warren County deputy coroner pronounced Jula dead at the scene at 11:17 p.m. He was wearing a seat belt.

Jula’s 2011 Nissan Rogue was totaled. The truck had moderate damage.

Jula is the son of Mark Jula, who coached at Butler from 1987 to 1993. In 1991, the team won its first WPIAL title since 1915 and set a school record with a 27-4 season.

Mark Jula now coaches at Ambridge High School.
