A Granite Falls man will likely spend the rest of his life behind bars after a judge on Tuesday handed down a sentence of more than 106 years in prison. A Chippewa County jury had earlier convicted him on 27 counts of criminal sexual conduct and stalking tied to repeated sexual and physical assaults, and jurors also found aggravating facts on 21 of those counts, which opened the door to a far longer sentence than usual. Prosecutors say he recorded many of the attacks and then weaponized the footage to keep the abuse going.
Prosecutors: Recorded assaults used as blackmail
According to a press release from the Attorney General’s Office, the crimes took place between July 2022 and December 2023 and involved repeated sexual and physical violence. Prosecutors say the defendant routinely filmed the assaults, then used the videos to pressure and blackmail the victim into additional sex acts.
Local coverage of the guilty verdict was carried by KSTP, which reported that the Attorney General’s Office took the case after a referral from Chippewa County.
State law enforcement posts sentence details
The Minnesota Bureau of Criminal Apprehension publicly announced the outcome on Tuesday in a social media post, stating that the defendant had been sentenced to "more than 106 years" in prison and sharing a booking photo credited to the Chippewa County Sheriff’s Office. The Minnesota Bureau of Criminal Apprehension post serves as the public notice of the sentence. Prosecutors had secured the convictions in April after a week-long jury trial.
How Minnesota handles long sentences in severe cases
Monitoring data from the Minnesota Sentencing Guidelines Commission show that first‑degree criminal sexual conduct cases can result in long aggregate prison terms when juries find multiple aggravating factors and courts stack sentences consecutively. The commission’s analysis notes that aggravated durational departures, used for circumstances such as particular cruelty or multiple incidents, are relatively rare but can lead to substantially longer prison time, according to the Minnesota Sentencing Guidelines Commission.
Prosecutors credit local investigators
The Attorney General’s Office, which handled the prosecution after the referral from the Chippewa County attorney, credited the Montevideo Police Department and the Minnesota Bureau of Criminal Apprehension for their investigative work. "McCalpin committed horrific crimes over a long period of time," Attorney General Keith Ellison said in an April statement. The earlier release lays out the charging timeline and the jury findings that shaped the lengthy sentence, according to the Attorney General’s Office.
Resources for survivors
Anyone affected by sexual assault or domestic violence can reach Minnesota victim services, including the Crime Victim Justice Unit at 651‑201‑7310 and the Minnesota Crime Victims Reparations Board at 877‑251‑7373.
