Michael Carbo, age 57, has again been sentenced to life in prison after being found guilty by a second jury for the 1986 rape and murder of Nancy Daugherty according to St. Louis County Attorney Kim Maki.

Carbo was first indicted by a Grand Jury in April 2022, for the rape and murder of Daugherty in her home in Chisholm after genetic genealogy pointed law enforcement to Carbo through his DNA left at the crime scene, explained the St. Louis County Attorney’s Office.

“In a divided opinion dated May 8, 2024, the Minnesota Supreme Court reversed Mr. Carbo’s conviction, finding that Mr. Carbo should have been allowed to present limited alternative-perpetrator evidence,” further explained the office.

A second jury trial was conducted in January 2025, and this jury also found Carbo guilty on both counts.

The jury determined that Carbo, when was 18-years-old, attacked 38-year-old Nancy Daugherty at her home wehre she lived alone.

“When questioned by law enforcement, Mr. Carbo denied knowing Ms. Daugherty or ever being inside her residence.  However, during the second trial he testified that he must have had a consensual sexual encounter with Ms. Daughtery, despite having no memory of it,” continued a release from the St. Louis County Attorney’s Office.

Carbo’s sentencing was delayed when Carbo challenged the jury’s conviction in district court.

“The family of Ms. Daugherty has shown the greatest strength and courage throughout this process, even though it has been extraordinarily long and painful,” said County Attorney Maki. “They endured uncertainty, frustration, and hardship, yet their resolve never wavered.”

“While no sentence can erase the harm done, this outcome marks a meaningful step toward justice. It sends a clear message that delays do not equal impunity: those who commit crimes will be held responsible,” continued County Attorney Maki.
