Echoes of the Unknown

In today's episode, we're traveling to the cold mountains outside Bergen, Norway, where in 1970 the burned body of a woman was found in a remote valley locals called “Death Valley.” She carried no identification.

Nobody knows who she was — or why she died there.

In today's episode, we're traveling to Liverpool, England in 1931, where a quiet insurance agent named William Wallace returned home to find his wife brutally murdered.

This strange case is widely regarded as one of Britain’s most famous unsolved murders.

In today's episode, we're traveling back to 1966, to a quiet hillside in Brazil, where two electronics technicians were found dead under strange circumstances. They had carried a bottle of water, a notebook, and a pair of masks made from sheets of lead. A cryptic note revealed they were supposed to swallow capsules, put on the masks, and wait. Decades later, investigators still don't know how they died ... or what they were waiting for.

In today's episode, we’re traveling back to 1964, when a quiet suburban neighborhood in Ohio was shattered by a brutal crime. Sixteen-year-old Beverly Jarosz was alone in her bedroom, just after Christmas, listening to music. By nightfall, she would be dead — the victim of a savage attack inside her own home. There were suspects, rumors, and confessions that went nowhere … but still no clear answers over half a century later.

Over half a century later, his baffling disappearance remains one of the most enduring unsolved mysteries in American history.
