A University of Wyoming student has been scheduled to stand trial Dec. 18 on charges he used an assumed name to write bad checks totaling around $100,000.

Charles D. Shiers, 23, of Laramie, entered not-guilty pleas Friday to three forgery charges before 2nd District Judge Ronald O. Hyde.Prosecutors allege Schiers assumed the name of northern Utah resident Timothy Porter by getting an Idaho driver's license in Porter's name. The defendant opened checking accounts under Porter's name and wrote bad checks, prosecuters say.

The charges say Schiers wrote a fraudulent $974.60 check to Sears in Ogden and a check for $3,356.53 to J.C. Penney Co. on July 21. He is also suspected of writing bad checks in Salt Lake City, Bountiful, Pocatello, Idaho Falls and Salt Lake County.

Schiers was arrested Oct. 30 in Laramie after a picture of the suspect appeared on a Utah Crime Solvers television spot. Two Jackson Hole, Wyo., residents recognized him and called authorities. Schiers once worked in Jackson Hole.
