A man has been arrested for a 2008 sexual assault that took place in Marion County. Police say on Thursday James Michael Murphy of Knoxville was transported from the Anamosa State Penitentiary to the Marion County Jail for an initial appearance on a Marion County warrant of sexual abuse in the 2nd degree.

Murphy’s arrest is connected to an August 2008 Marion County Sheriff’s Office investigation, in which a female arrived at a local emergency room reporting she was abducted at knife point, taken to another location, and sexually assaulted by an unknown male assailant.

The victim submitted to a sexual assault examination, in which DNA evidence was collected. In 2014, a different sexual assault report was taken in another Iowa county where the assailant was identified as Murphy. His DNA profile was entered into the CODIS DNA database, and police say his was a match to the profile identified in the Marion County 2008 sexual assault.

In December, the Marion County Sheriff’s office says a report was generated by the DCI laboratory stating “the probability of finding this profile in a population of unrelated individuals, chosen at random, would be less than 1 out of 100 billion.”

A court appearance is scheduled for January 22nd.
