Delays could derail Iron Range cold case cracked with genealogy databases Evidence requested from DNA firm hasn't been produced in 1986 killing. February 16, 2021 — 2:41pm Text size Copy shortlink: DULUTH – In July the Minnesota Bureau of Criminal Apprehension and Chisholm police announced they had cracked a 34-year-old murder case using DNA evidence and public genealogy databases, leading to the arrest of an Iron Range man. But on Tuesday a judge warned if that evidence isn't provided soon the suspect could "at minimum" be released from jail. Michael Carbo Jr., 52, has been charged with second-degree murder in the 1986 killing of Nancy Daugherty and has yet to make a plea due to delays in the case. The Chisholm man has been held at the St. Louis County Jail on $1 million bail since last summer.
