Yorkville Man Learns Prison Sentence For Sexually Assaulting Girl: State's Attorney

YORKVILLE, IL — A Yorkville man was sentenced to 12 years in prison after he was found to have sexually assaulted a girl beginning when she was 9 years old, Kendall County State's Attorney Eric Weis said.

Following a three-day trial in October, a jury found Chaske Roskopf, 24, guilty of two counts of aggravated criminal sexual assault, punishable with up to 30 years in prison. Judge Gleason sentenced Roskopf to the minimum sentence of 6 years in prison on each count. The sentencing came after a contested hearing.

Charges were filed in 2022 after a Kendall County Sheriff's Office investigation revealed Roskopf had been sexually assaulting the young girl "by using force." The assault continued until the victim was almost 13, according to Weis.

Roskopf admitted to some of the sexual assaults, but "only to some acts and only when he himself was a minor," Weis said.

"He further admitted that [the assault] occurred in his home," the state's attorney said. Jail logs list Roskopf's address in the 0-99 block of Countryview Drive.

The victim and her mother both testified in court.

Roskopf is required to serve 85 percent of his 12-year sentence before being eligible for mandatory supervised release. He must also register for life as a child sexual offender.
