Authorities are asking for help finding a college student from St. Jacob who was reported missing Monday night by his relatives.

Sheriff’s deputies are looking for Taylor S. Clark, 19, of the 400 block of West Fifth Street in St. Jacob. Police said Clark was last seen by his girlfriend in Glen Carbon about 10:30 a.m. Monday after he finished taking exams at Southern Illinois University at Edwardsville.

Authorities said Clark was driving a red 2007 Nissan 350ZX with Illinois plate P845960. His family told investigators Clark had listed the car for sale on Craigslist, and spoken to someone Monday morning about the ad. Authorities aren’t sure if Clark met anyone to discuss selling the car.

Cellphone records indicate Clark’s phone was near the St. Louis Mills outlet mall in Hazelwood about 11:37 a.m. Monday.

Investigators said Clark has no history of running off or medical conditions. His car has not been found.

The Madison County sheriff’s office is asking anyone with information about Clark’s whereabouts to call investigators at 618-692-0871 or 618-296-3000.
