DNA technology links McDowell County burglaries, leads to charges against Marion woman

Two McDowell County burglaries that had lingered for years moved back into the justice system when DNA evidence linked them to Shannon Nicole Mills, 33, of Marion. The cases, one from a residence on Mack Noblitt Road in 2020 and another from a storage unit in Marion in 2023, show how older evidence can still produce arrests long after the break-ins.

The McDowell County Sheriff’s Office said advances in DNA technology, along with work by Detectives Billie Brown and Derrick McGinnis, allowed investigators to connect the two cases through the Combined DNA Index System, known as CODIS. Mills was charged with felony second-degree burglary and felony larceny after breaking and entering. A third felony count was also listed in the report, though the public preview did not spell out the charge.

CODIS is the FBI’s national system for comparing DNA profiles from crime scenes with profiles already in criminal justice databases. In North Carolina, a CODIS hit occurs when an unknown profile matches an offender or arrestee profile already on file. State officials say the North Carolina DNA database now holds more than 380,000 profiles, and a briefing for the North Carolina General Assembly says analysts can compare crime-scene evidence against more than 450,000 profiles in the laboratory database when no suspect is known.

For McDowell County, the case is about more than one Marion woman and two burglary files. It shows that evidence preserved in a property-crime investigation can still matter years later, especially in a rural county where investigators may have to revisit old casework and push it through modern forensic systems before they get a match. That kind of follow-up can be crucial for homeowners, landlords and business owners who may otherwise see a burglary fade into the background of a crowded caseload.

McDowell County Sheriff Ricky T. Buchanan oversees an office based at 593 Spaulding Road in Marion, where deputies handle jail operations, courthouse security and service of papers in addition to criminal investigations. The county’s latest arrest points to a broader lesson for residents: old burglary cases are not always closed forever, and DNA technology can reopen them with consequences for both suspects and the public’s expectation of accountability.
