Minnesota man charged with forcing teenage relative to have sex with adult women

A Minnesota man faces multiple felony charges after accusations that he pressured a teenage relative into having sex with adult women.

William Roy Witt, 39, of Montevideo is charged in Chippewa and Lyon counties of criminal sexual conduct and aiding and abetting criminal sexual conduct.

Also charged with various counts of felony criminal sexual conduct are three women said to be Witt’s girlfriends at various points: Maria Isabel Rios, 44, of Montevideo; Kimberly Kay Klein, 43, of Vesta; and Sarah Marie Riederer, 43, of Springfield.

The charges are related to the alleged sexual abuse of the boy over several years and across multiple counties, according to criminal complaints against Witt and the three women.

The investigation began after a child protection report from Chippewa County Family Services was received in January, investigators at the Redwood Falls Police Department said in a criminal complaint. The victim was living with his mother in Iowa at the time.

The complaints detail allegations that Witt arranged for and sometimes participated in sexual encounters between the boy and the three women.

The alleged abuse began around the boy’s 15th birthday in March 2022, and continued until late 2024, occurring in Redwood Falls, Montevideo, Marshall and Springfield.

According to the complaints, the boy reportedly stated that Witt would coax him into sex with the women. Witt sometimes provided alcohol and set up DJ equipment for group sex at his home in Redwood Falls, which has since been demolished.

The boy said he didn’t feel he could say no to Witt, who allegedly told him at one point to “be a man.”

The boy described feeling uncomfortable and that he eventually cut off contact with Witt. He reportedly suffered stress and mental anguish as a result, requiring therapy.

Court documents state that during interviews with law enforcement, Rios and Klein admitted to sexual contact with the minor, alleging Witt had encouraged or persuaded them.

Police said Rios stated the minor was 16 at the time of some incidents. Charges said Klein admitted the encounters began in Marshall on the boy’s 15th birthday as a “gift” arranged by Witt.

Police said they spoke with Witt on March 22 and that initially he denied knowing whether the boy had been victimized, but then admitted to investigators that he dated the three women and that group sex sessions involving himself, the boy and Rios occurred numerous times.

Charges against the man and three women include first- and third-degree criminal sexual conduct.

Witt was in custody at the Chippewa County jail as of Thursday, according to an inmate roster.

Jeremy Blackwelder, a Granite Falls-based attorney listed as representing Witt, declined in a phone call to comment on the case.
