ST. PAUL, MN-- The Bureau of Criminal Apprehension (BCA) and the Chisholm Police Department have made an arrest for the murder of Nancy Daugherty.
Michael Allan Carbo Jr., 52, of Chisholm, was taken into custody early Wednesday and booked at St. Louis County Jail in Virginia.
He was charged with probable cause 2nd Degree Murder.
According to officials, after receiving confirmation from the BCA laboratory Wednesday that Carbo’s DNA matched DNA from the crime scene, the arrest was made.
Nancy Daugherty was last seen alive just after Midnight on July 16, 1986.
That afternoon, Chisholm police officers conducting a welfare check located Nancy Daugherty deceased inside of her home.
Officials say she was found beaten, sexually assaulted and strangled.
Evidence at the scene indicated that a struggle had occurred both outside and inside the home. Witnesses later reported hearing a woman screaming in the early morning hours.
BCA scientists obtained a full DNA suspect profile from bodily fluids found on the victim and at the scene. But the DNA did not match any persons in the criminal DNA database.
Records show, over the years investigators interviewed and collected DNA from more than 100 people.
Periodic case reviews also took place but no solid leads. Back then periodic comparisons of evidence DNA to the DNA database did not result in a match either.
