A county prosecutor says Attorney General Mike Cox's office is investigating the case that led to the wrongful murder conviction of a man for the slaying of a Lansing Community College professor.
Claude McCollum was convicted in 2006 of murdering 60-year-old Carolyn Kronenberg. Authorities threw out the conviction in October. State police say another man is responsible.
Ingham County Prosecutor Stuart Dunnings III tells the Lansing State Journal that the attorney general's office has asked for materials on the McCollum investigation.
Dunnings earlier requested an independent review of how evidence was handled in the case.
