DUNN COUNTY (WQOW) - A River Falls man could spend more than 60 years behind bars if convicted of child sexual assault charges.

Derek P. Johnson was charged in Dunn County with first degree sexual assault of a child under the age of 12 on Tuesday. 

According to the criminal complaint, the victim told authorities the assault happened three to four years ago in Boyceville when she would have been 9 years old. She said Johnson told her if she told anyone about it, he would do the same thing to her younger sister, who was 2 or 3 years old at the time.

Johnson is due in court at the end of the month for an initial appearance.
