Man sentenced to life for Iron Range killing
DULUTH, Minn. (AP) — A man convicted of raping and killing a woman 36 years ago on Minnesota’s Iron Range was sentenced Friday to life in prison. Michael Allan Carbo Jr., 54, of Chisholm, was charged with two counts of first-degree murder while committing criminal sexual conduct in the 1986 slaying of 38-year-old Nancy Daugherty, also of Chisholm. The case was eventually revived by genealogy database analysts. A jury convicted Carbo in August. Daugherty was found dead in her home on July 16, 1986, by police conducting a welfare check. Investigators over the years interviewed and collected DNA from more than 100 people but were unable to find a solid lead.
