A memorial service for an SIU Athletic Department worker who died in a fiery car crash is Tuesday.

The service for 26-year-old Corey Lee Warren of Marion is scheduled for 1 p.m. at West Bourbon Elementary School in Uniontown, Kansas.

The Jackson County Sherriff’s office says Warren died in the crash during the overnight hours between June 9 and 10. He was driving a university-owned vehicle when the Sheriff’s office says he failed to negotiate a turn and struck a tree.

Authorities say they are waiting for a final report from a forensic pathologist before ruling an exact cause of death.

Warren was a graduate assistant coach for Saluki Football and before that, he was a linebacker at Kansas State.
