WILLISTON, N.D. -- A 42-year-old Williston man was sentenced Thursday, Dec. 5, to 15 years in prison for raping a 12-year-old girl multiple times in 2017.

Juan Antonio Martinez was convicted in February of continuous sexual abuse of a child, a class AA felony. During the three-day trial, the girl testified that Martinez raped her as many as nine times when she was 12 years old.

At a sentencing hearing Thursday, Nathan Madden, assistant state's attorney for Williams County, asked Northwest District Judge Benjamen Johnson to sentence Martinez to serve 20 years in prison and spend five years on probation. William Sand, Martinez's defense attorney, asked for a sentence of six years to serve with probation to follow. Sand argued that a lighter sentence was justified because Martinez had no criminal history and a presentence investigation and risk assessment found he was a lower-than-average risk to re-offend.

Johnson said he wasn't going to follow either side's recommendation. He sentenced Martinez to 20 years in prison with five years suspended and ordered him to serve 10 years of probation after he's released.

Martinez will also have to register as a sex offender and is not allowed to have any contact with the girl while in prison or on probation.
