CHISHOLM, MN -- A judge set bail at $1 million Thursday for a Chisholm man charged in connection with a murder 34 years ago on the Iron Range.
Michael Allan Carbo, Jr., 52, was charged with second degree murder Thursday in St. Louis County Court.
Carbo was arrested Wednesday after DNA evidence matched DNA collected at scene where Nancy Daugherty's body was found in 1986.
Officials say Daugherty was last seen alive just after midnight on July 16, 1986.
Police found her body inside her home after conducting a welfare check. Officials say she was found beaten, sexually assaulted and strangled.
It wasn't until July 2020 that new scientific methods helped match Carbo to the crime scene.
According to court documents, law enforcement learned that Carbo was living less than a mile from the crime scene in 1986 and attended school with Daugherty's children.
Before they made an arrest, law enforcement began surveilling Carbo's Chisholm apartment on July 23.
According to court documents, authorities also collected DNA evidence from Carbo's garbage they watched him carry outside. They sent the garbage in for DNA testing
Several days later, law enforcement learned the DNA collected from Carbo's garbage also matched evidence collected at the crime scene.
On July 29, law enforcement received a DNA sample from Carbo and sent it to the BCA laboratory for testing. After testing, Carbo's DNA profile was consistent with the DNA profile, according to court documents.
Court documents did not shed light on a motive for the murder.
Carbo is due back in court August 6.
