A Wisconsin nurse who admitted to having sex with a patient and then falsely accusing him of sexual assault in an attempt to avoid consequences has been sentenced to prison.

Melissa Knutson was sentenced to 18 months behind bars after pleading guilty to misconduct in public office and obstructing an officer, according to the Monroe County District Attorney’s Office.

Following her release, Knutson will also face two years of public supervision.

The case centers on a deeply troubling breach of professional trust that prosecutors say escalated into a damaging false accusation.

According to investigators, Knutson was working as a nurse assigned to a man participating in drug court — a program designed to help individuals with substance abuse issues avoid traditional incarceration through supervised treatment and monitoring.

While serving in that role, prosecutors said Knutson “repeatedly” engaged in sexual intercourse with the patient.

The relationship came to light after the encounters were reported to the Wisconsin Department of Safety and Professional Services, the agency that oversees professional licensing in the state.

Facing potential disciplinary consequences, Knutson made a dramatic allegation.

Prosecutors say she accused the patient of sexually assaulting her.

The claim launched a serious investigation, but authorities later determined that the accusation was false.

Eventually, Knutson admitted that she had fabricated the allegation.

According to prosecutors, she confessed that she made the false claim in an attempt to avoid accountability for engaging in sexual conduct with a patient under her care.

The revelation turned the investigation into a criminal case against the nurse herself.

During sentencing, Judge Paul Curran sharply criticized Knutson’s conduct, describing her actions as both unethical and harmful.

He called her behavior “despicable” and said she was “an embarrassment to nurses everywhere.”

The judge also expressed skepticism about Knutson’s expressions of remorse.

Curran said he believed her apology was “a mile wide and an inch deep,” suggesting her regret did not fully reflect the seriousness of what had happened.

Prosecutors echoed that concern, emphasizing the broader damage caused by the false accusation.

“The harm caused by Ms. Knutson was deep and significant,” Monroe County District Attorney Kevin Croninger said in a statement.

“Not only did she violate the sacred trust between a patient and a nurse, but she compounded that by falsely accusing the patient of sexual assault.”

Croninger also noted that the patient’s participation in drug court made the situation particularly troubling.

Drug court programs are designed to provide structure and support for people attempting to rebuild their lives while battling addiction. Participants are closely monitored by courts and professionals who are expected to uphold strict ethical standards.

According to prosecutors, Knutson’s actions undermined that system and put a vulnerable individual at risk.

For Knutson, the consequences now include prison time, the likely loss of her nursing career, and a criminal record.
