August 20, 1966. Niteroi, Brazil. The bodies of a pair of electronics technicians, 34-year old Miguel Jose Viana and 32-year old Manuel Pereira da Cruz, are discovered on the top of Vintem Hill and they are carrying a pair of lead masks and some cryptic notes about ingesting capsules. Three days earlier, the two men had travelled to Niteroi from their homes in Campos dos Goytacazes over 260 kilometres away, but there is no direct evidence of foul play and the authorities are unable to determine their cause of death. There are a number of theories about what happened, including speculation that the two men’s deaths might be connected to UFO sightings from the area, but the whole situation is never satisfactorily explained and remains shrouded in mystery. For this year’s Halloween-themed episode, “The Trail Went Cold” is finally tackling one of the most bizarre unsolved mysteries of all time: the Lead Masks Case.
