Righting a Wrong On the Case with Paula Zahn : Season 26 Episode 11

July 16, 1987, Chisholm, Minnesota: 38-year-old Nancy Daugherty was found dead in her home. She had been raped and strangled. Law enforcement detectives worked the criminal case, but came up empty-handed, and the investigation went cold for decades. Eventually, DNA evidence and genetic genealogy helped solve this crime. In August 2022, Michael Carbo, Jr. went to trial for Nancy's murder and was found guilty. Carbo was sentenced to life in prison. He had only been 18 years old at the time he killed Nancy.
