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.

March 6, 1939. Fingringhoe, England. After purchasing some cigarettes at a local pub, 67-year old Ada Constance Kent seems to disappear and over the course of the next decade, numerous searches are performed of her empty cottage and they fail to turn up any trace of her. Ten years later, a human skeleton is discovered beneath some rubble in the cottage’s bedroom alongside an empty bottle of poison, and after a forensic examination is performed, there is some uncertainty about who the remains actually belong to. When an inquest is held, a coroner’s jury does eventually conclude that the skeleton is likely Ada Constance Kent, but since they are unable to determine her exact cause of death, they return an open verdict. Did Ada Constance Kent die inside her cottage and remain undiscovered for an entire decade? If not, then what actually happened to her? On this week’s episode of “The Trail Went Cold”, we travel back to the United Kingdom to explore a truly bizarre mystery.

October 31, 1963. Newcastle, England. 70-year old Katherine Lillian Armstrong fails to show up for choir practice at her church. The following morning, Lillian’s body is discovered near the bottom of the staircase in her house and she has been stabbed 28 times and strangled with one of her nylon stockings. Since there are no signs of forced entry, police suspect that Lillian willingly let her killer inside, but even though a massive investigation is launched, no compelling suspects are found and the motive for the crime remains unknown.

October 31, 1980. Bristol, England. 39-year old Derek Grain leaves his hotel and spends the night drinking at a pair of local nightclubs. After leaving one of the clubs during the early morning hours, Derek is later found dead in a pool of blood a quarter-mile away and it turns out he was kicked in the head and bludgeoned with a sand-filled traffic cone. Since money was stolen from Derek, it is theorized that he was the victim of a robbery gone wrong, but even though there are reported eyewitness sightings of someone being attacked by multiple people who fled the scene in a maroon Jaguar, the crime is never solved.

On this week’s episode of “The Trail Went Cold”, we travel to the United Kingdom to explore a pair of unsolved murders which happened to take place on Halloween.
