(Ottawa County, MI) – A Coopersville man who is accused of assaulting his step-granddaughter is accepting a plea deal. Stephen Chesla is accused of sexually assaulting the child in 2020 and had been granted a retrial after being convicted and sentenced to a minimum of 35-years in prison. Instead of the new trial taking place, Chesla has pleaded guilty to assault with intent to commit criminal sexual conduct and in exchange, other charges were dropped.
