CHISHOLM, Minn. Investigation Discovery will shine a light on a Minnesota murder Wednesday evening, focusing on the 1986 murder of Nancy Daugherty that, for decades, went unsolved.
“On the Case with Paula Zahn” will air “Righting a Wrong” the episode featuring the Nancy Daugherty case on Wednesday, July 19, at 9 p.m. Central Standard Time.
Daugherty was 38 years old when she was attacked and killed in her Chisholm home in 1986. She was discovered by local officers conducting a welfare check. When they arrived at her home, they quickly realized something was terribly wrong. Daugherty had been sexually assaulted and left to die.
For 36 years, the case remained unsolved until 2020, when DNA technology directed investigators to a man who lived just blocks from Daugherty at the time of her death.
Michael Allen Carbo Jr. was convicted in 2022 for first-degree murder and sentenced to life in prison. He was 18 years old at the time of the murder. At the time of his sentencing, Carbo was 54 years old.
“Award winning journalist Paula Zahn unravels shocking crimes interviewing those closest to the case including lawyers, the victim’s family, and detectives,” reads the ID show description for “On the Case with Paula Zahn.”
The Nancy Daugherty episode is 60 minutes long, with the following description:
“In July of 1986, the Chisholm Police Department in Minnesota received a call about trouble at the home of 38-year-old Nancy Daugherty. Nancy’s close friend Brian, who had visited her house several times that day, convinced dispatchers that the circumstances were concerning enough for a welfare check. Brian and the responding officer were able to get into her home and their search revealed a horrific sight, Nancy had been murdered in what appeared to have been a sexually motivated attack. Investigators discovered some odd clues in her bedroom and several more in Nancy’s backyard, but none of the evidence pointed to a suspect. Despite a team of dedicated detectives who knew and cared about Nancy, it quickly became clear that righting this wrong would be extremely difficult.”
