DAYTONA BEACH, Fla. -

A St. Augustine man designated as a career criminal will spend the next 20 years in state prison.

Curtis Williams, 43, was convicted by a St. Johns County jury in July of sexual battery and misdemeanor battery.

Evidence at trial showed that Williams punched the victim in the face and then sexually battered her. Williams was designated a career criminal based on his 14 prior felony convictions and 16 prior misdemeanor convictions. His extensive criminal history includes drug sale convictions, aggravated assault, escape, grant theft, battery on a law enforcement officer, resisting an officer with violence, and several other violent and nonviolent charges.

Williams was sentenced as an habitual felony offender, which allows for the judge to sentence to double the maximum possible sentence, in this case from 15 years in prison to 30.

Williams also earned a prison release reoffender designation, meaning his first 15 years in prison will be day for day. Following his release from state prison, Williams will face 10 years of sex-offender probation.
