A Superior man will spend 12 years in state prison after pleading guilty to first-degree child sex assault.

Tazz Michael Sherman, 20, pleaded guilty April 29 in Douglas County Circuit Court to one count of first-degree child sex assault.

On June 28, he was sentenced to 12 years in prison and 13 years of extended supervision. Sherman was ordered to register as a sex offender and have no contact with children under age 18, the victim or the victim's family.

An additional count of first-degree child sex assault was dismissed but read in for sentencing.

According to the criminal complaint, Superior Police Detective Mike Jaszczak and a Douglas County social worker participated in a forensic interview with the victim, who was age 7 at the time of the reported assaults. According to the victim’s account, Sherman threatened the victim with a “time out” if she did not cooperate in two separate assaults.
