A Scott County judge sentenced Michael John Anderson, 20, to life in prison without parole on Wednesday for the 2007 slaying of Katherine Ann Olson, a 24-year-old Cottage Grove native, according to published reports.

Anderson was convicted Tuesday of first-degree murder in the murder of Olson, whom he lured to his parents’ Savage home in October 2007 posing as a woman in search of a babysitter on

He then shot Olson in the back and left her body in the trunk of her car at a Burnsville park.

District Judge Mary Theisen delivered the sentence required by law for a first-degree murder conviction. Anderson’s defense attorney had argued that the murder of Olson was unplanned; jurors found otherwise.

According to reports, Anderson declined to speak at the Wednesday morning sentencing. Olson’s family members, including her parents who still reside in Cottage Grove, gave impact statements to the judge, describing how the murder had affected them.

Family and friends of Katherine Ann Olson are planning a tribute concert May 3. For information go to:
