On December 10, 2019, Mark Robert Olson, a 60-year-old Ft. Gratiot man, was arraigned before Magistrate Susan Borovich in 72nd District Court in Port Huron. Olson has been under investigation since November of 2019 when an anonymous tip was received through the Port Huron Police Capture program. The case was eventually turned over to the St. Clair County Sheriff’s office where they uncovered multiple criminal sex acts involving Olson between 2001 and 2008.
Upon investigation, Olson was found to be in possession of child pornography. “We are deeply disturbed with the allegations regarding this suspect,” said Sheriff Tim Donnellon. Olson is being held without bond at the St. Clair County Intervention and Detention Center. He is being charged with five counts of first degree criminal sexual conduct and three counts of possession of child sexually abusive material.
This is an ongoing investigation, with more charges against Olson expected. Anyone who was a victim or has any information regarding this case should contact Detective Haley Bonner at (810) 987-1728.
