In his closing argument Wednesday, prosecutor Vic Braden went over the evidence, telling the jury that Thurber intended to kill Sanderholm and that he made her suffer.
The defense did not present any witnesses or a closing argument.
In the morning session, the final piece of DNA evidence presented to the jury was found underneath Sanderholm's fingernails. Experts testified that it matched Thurber's DNA.
The College student was found dead in a wildlife area near Arkansas City in January 2007.
