After nearly four decades, a man whose skull was discovered in the New Hampshire woods has been identified.

Warren Kuchinsky was born in 1952 and was last known to be alive in the mid-1970s, New Hampshire Attorney General John Formella and New Hampshire State Police Colonel Mark Hall said in a statement. In 1986, his skull was found in a wooded area in the town of Bristol.

At the time, investigators weren’t able to identify whose skull it was, according to officials. Last year, however, the Office of the Chief Medical Examiner partnered with the DNA Doe Project, a nonprofit organization, to solve the case using forensic genetic genealogy techniques.

Kuchinsky’s identity was confirmed through DNA testing of a surviving family member, according to officials. There is no evidence that his death was caused by foul play, according to the statement.

Founded in 2017, the DNA Doe Project partners with law enforcement, medical examiners, and volunteer genealogists to apply investigative genealogy to John and Jane Doe cases. By analyzing DNA profiles and building family trees from publicly available genetic databases and historical records, the organization has helped solve more than 250 cases nationwide.

“We are honored to have partnered with the State of New Hampshire on this case,” DNA Doe Project Team Leader Lisa Ivany said in the statement. “Through the power of investigative genetic genealogy and the dedication of our volunteer genealogists, we were able to develop a critical lead in less than 24 hours. We truly hope that this identification brings long-awaited answers to Mr. Kuchinsky’s family.”

Initial DNA testing turned up only distant matches, so the DNA Doe Project selected the case to be worked on at a virtual retreat in May 2025, according to the organization’s case profile. Over the course of a weekend, more than 40 genealogists from the U.S., Canada, England, and Scotland collaborated virtually to work on the case.

Within hours, the team discovered that the unidentified man had roots in New Hampshire and Quebec, according to the profile. They later zeroed in on Kuchinsky, who had attended school in Plymouth, N.H., but had no official proof of life past 1970.

“This identification reflects the power of partnership and scientific advancement,” Formella said in the statement. “The dedication of the Office of the Chief Medical Examiner, the investigative support of the New Hampshire State Police, and the extraordinary work of the DNA Doe Project have restored a name to an individual who had been unidentified for nearly 40 years. We are grateful for their professionalism and commitment.”
