CALHOUN COUNTY, Mich. – A Michigan man has been sentenced to 17-40 years in prison for repeatedly sexually assaulting a minor over several years, officials said.

John Hendrickson, 59, of Bellaire, pleaded no contest to four counts of first-degree criminal sexual conduct in August.

In January, he was also charged with three counts of first-degree criminal sexual conduct in Allegan County and another in Calhoun County, but those were dismissed because of the plea deal.

Following his prison sentence, Hendrickson will have lifetime electronic monitoring and sex offender registration.

“Sexual assault is a heinous crime that leaves lasting scars,” Michigan Attorney General Dana Nessel said at the time the defendant entered the plea. “I am grateful that we were able to secure justice for the victim in this case without prolonging their suffering with a lawsuit. The courage of the victim to come forward after years of abuse is truly inspiring. I want to reassure all victims of sexual assault that my Department is committed to supporting survivors and ensuring that perpetrators are held accountable, no matter how many years have passed.”
