New Hampshire law enforcement officials recently resolved a cold case involving the 2007 death of Carrie Hicks in the town of Acworth. While the incident was initially linked to a potential suicide pact, a modern forensic re-examination of blood patterns and autopsy records proved that Hicks was murdered by Wayne Ring. Experts concluded that the victim was physically incapable of inflicting her own wounds, confirming that Ring shot her before attempting to take his own life. Although the state determined there was enough evidence to pursue first-degree murder charges, the suspect passed away in 2012. Consequently, the Attorney General’s Office has officially closed the investigation, providing the family with long-awaited answers regarding the tragedy. This breakthrough highlights the ongoing efforts of the Cold Case Unit to utilize advanced technology to settle decades-old mysteries.

A cold case from 1999 involving a sexual battery in Naples, Florida, has finally been solved through the use of forensic genetic genealogy. Authorities identified Terry Lynn Denton as the primary suspect after investigators secretly obtained his DNA from a metal fork he used at a restaurant in Arizona. This genetic profile provided a definitive match to evidence collected from the victim over twenty-seven years ago. Although Denton claimed he never lived in the area, public records placed his residence less than a mile from the crime scene at the time of the attack. The Collier County Sheriff's Office successfully arrested the seventy-one-year-old, marking their first successful closure of a cold case using this advanced biological testing method. He is currently awaiting extradition to Florida to face formal charges for the decades-old assault.
