A Flint man is heading to prison for sexually assaulting a child.

33-year-old Andrew Parker, convicted last month of first-degree criminal sexual conduct with a person under the age of 13, was sentenced Monday in a Genesee County court to 25 years in prison. An investigation into Parker began when a grandmother of the victim approached paramedics in the area of South Saginaw Street and Bristol Road and told them of the assaults. The information was passed onto the Genesee County Sheriff’s Department.
