USA: The mystery of “Pinnacle Man” solved after 50 years – He was found frozen in a cave but his identity was unknown
The man, who was found frozen in a cave at Pinnacle, a popular destination along the Appalachian Trail, has been identified as Nicholas Paul Grabb, a 27-year-old from Fort Washington. This identification brings relief to his family, who for 47 years had no idea what happened to him, although many questions remain about the last days of his life.
