A man who was found frozen in a Pennsylvania cave nearly five decades ago has been identified by officials as 27-year-old Nicolas Grubb from Fort Washington, Pennsylvania. Grubb, a member of the Pennsylvania Army National Guard in the early 1970s, was known as the 'Pinnacle Man' after his body was discovered by hikers near the Pinnacle, a popular peak along the Appalachian Trail on January 16, 1977.
The body, frozen solid due to record-low temperatures, showed no signs of foul play, and authorities ruled the death as a suicide from a drug overdose. Despite efforts to identify Grubb through dental records and fingerprints, the case remained unsolved for years.
