A former University of Iowa student accused of attempted murder is expected to plead guilty, although it is unknown to what charges, according to court documents.

Branden Plummer is accused of the Class-B felony and willfully causing bodily injury, a Class-D felony, in connection with an alleged assault of Iowa City police Sgt. Brian Krei.

On Nov. 18, 2011, police reports said Krei approached Plummer because he was allegedly disrupting traffic. Plummer allegedly started to strangle Krei and hit Krei’s head against the sidewalk, causing him to lose consciousness.

Plummer was also granted a request to modify his bond on Sept. 14. His mother posted his bond, which was originally set at $100,000 cash, on Dec. 27, 2011.  Plummer’s bond was reduced to $50,000, and the remaining $50,000 will be returned to his mother, Kerrie Murphy.

Plummer will plead guilty at 9 a.m. Sept. 21. His trial is currently set for Sept. 24 at the Tama County Courthouse, but it is currently unclear as to where he would plead guilty.
