TROY, Ill. (AP) – Farmily and friends have said goodbye to a Southern Illinois University student who police say was killed while trying to sell his sports car advertised on Craigslist.

A funeral Mass for 19-year-old Taylor Clark of St. Jacob, Illinois, was held Tuesday at St. Jerome Catholic Church in Troy, followed by burial services.

Authorities say Clark went missing May 4 after being contacted about his 2007 Nissan 350ZX he was trying to sell on an online marketplace. His car and body were found the next day at a Hazelwood, Missouri, business where 24-year-old Michael Gordon worked.

Gordon is charged with first-degree murder and armed criminal action in Clark’s death.

Online court records don’t show whether Gordon has an attorney.

Clark was a sophomore engineering student at Southern Illinois University in Edwardsville.
