A Suffield man on trial for sexually assaulting a child pleaded guilty Tuesday rather than leave his fate in the hands of the jury.

Michael Chapman, 44, pleaded guilty to first-degree sexual assault and risk of injury to a minor. He agreed to a sentence of 13 years in prison, 10 years of special parole and registration as a sex offender.

The plea came after several days of trial in Superior Court in Rockville and the testimony of Chapman’s young victim. Chapman will be sentenced Tuesday.

Chapman was initially charged with four counts of first-degree sexual assault and three counts of risk of injury to a minor for a series of sexual assaults that occurred in Tolland County.

State police investigated the allegations and brought charges. Assistant State’s Attorney Elizabeth Leaming prosecuted Chapman.
