On the evening of Aug. 4, 1900, 5-year-old Tommy Jones went missing near his grandfather’s farm in Brecon, South Wales. A 29-day search of the surrounding country found no trace of him.

His body was finally discovered on Pen y Fan, the highest mountain in South Wales, at an altitude of 1,300 feet. He had died of exhaustion and exposure. No one knows what led him there.

Strangely, almost the same thing had happened 10 years earlier in Virginia.
