A former Monroe County nurse was sentenced to 18 months in prison Friday after authorities said she had a sexual relationship with a patient in a drug court program and then falsely accused the patient of sexual assault when the investigation into the relationship began.
Melissa Knutson, 30, of Readstown, was also sentenced to serve two years of extended supervision after her prison term, after she pleaded guilty to a charge of misconduct in public office.
The charges stem from Knutson’s employment as a nurse in Monroe County, where she cared for drug court participants. Authorities said Knutson several times engaged in sexual intercourse with a male patient to whom she administered medication as part of his drug treatment program.
Drug court is a program that provides treatment and supervision to people who have a drug problem but are not incarcerated. Participants are under court supervision and are subject to strict compliance requirements.
According to court documents, the case came to light when the Wisconsin Department of Safety and Professional Services received reports of an improper relationship between Knutson and the patient.
When the case was first discovered, Knutson claimed that the patient had sexually assaulted her, but during the plea hearing, she confessed that she had made a false accusation.
The investigators later retrieved text messages between Knutson and the patient that contradicted Knutson’s claims. The text messages revealed that Knutson had initiated the improper relationship and that she would deny it if she were caught.
According to court documents, in one of the text message exchanges, Knutson hinted that she would deny any wrongdoing if the improper relationship came to light.
Knutson was arrested in March 2025.
