The Bureau of Criminal Apprehension and the Chisholm Police Department announced Wednesday evening that they have made an arrest in the 1986 murder of Nancy Daugherty of Chisholm.

The suspect is 52-year-old Michael Allen Carbo Jr. of Chisholm.

Carbo was arrested Wednesday and booked into the St. Louis County Jail on probable cause of 2nd Degree Murder. He is awaiting arraignment.

According to police, Carbo was 17-years-old at the time of Daugherty's murder. Police do not believe Carbo and Daugherty knew each other.

Police say Carbo had some minor charges, but did not say what those charges were. They added that Carbo had not been a person of interest in their investigation, despite having interviewed hundreds of suspects in Daugherty's murder.

Daugherty was last seen alive just after Midnight on July 16, 1986. That afternoon, Chisholm police officers conducting a welfare check located her body inside of her home. She had been 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.

In early 2020, the Chisholm Police Department approached the BCA wanting to provide a sample of the DNA evidence to Parabon. The company analyzes public genealogy databases that have law enforcement programs to generate leads in cases. The BCA laboratory coordinated with the company to provide a DNA sample from the decades-old evidence. Based on their analysis and search, Parabon in July identified the suspect as a potential suspect in the case. 

BCA agents and Chisholm investigators began surveillance on the suspect last week and surreptitiously obtained DNA evidence that was sent to the BCA laboratory for analysis.

On Monday, the BCA laboratory reported a DNA match to the bodily fluids found on the victim and at the scene. Wednesday morning, investigators obtained a DNA sample directly from the suspect with his consent. The BCA laboratory tested the known DNA sample, providing confirmation this afternoon of a DNA match.

"We are gratified to be able to provide some answers to this family and this community after all of these years," Chisholm Police Chief Vern Manner said. "We are grateful as well to the BCA and so many assisting law enforcement agencies that continued to work this case over more than three decades."

"This case illustrates why no case is ever cold for us," BCA Superintendent Drew Evans said. "Every time we hit a dead end, investigators and scientists go back to the drawing board. Solving this case is proof of the value of tenacious work – even when it's over a span of decades."

Carbo will be charged in the days ahead by the St. Louis County Attorney's Office. This remains an ongoing and active investigation.
