A Douglas County judge sentenced a 21-year-old Belton, Mo., man to serve a five-year prison sentence for his involvement in a 2009 robbery on the Kansas University campus.

District Judge Kay Huff on Tuesday also ordered Mykel Dantae Karlyle to register as a violent offender once he’s released because a firearm was used during the crime. He had pleaded no contest to one count of aggravated robbery.

Prosecutors accused him of using a handgun to rob a student of marijuana on April 29, 2009, in the parking lot outside McCollum Hall. Prosecutors said the victim believed he was going to sell marijuana when he was robbed. Karlyle also faces aggravated robbery and aggravated battery charges for a 2011 incident in Shawnee County.

A co-defendant in the Lawrence case, Terrance A. Dean, 21, of Topeka, entered a plea to conspiracy to commit robbery in January and faces a Feb. 28 sentencing.
