Echoes of the Unknown

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.

In today's episode, we're traveling back to the summer of 1975, when former Teamsters boss Jimmy Hoffa walked into the parking lot of a suburban Detroit restaurant to attend a meeting — and was NEVER seen again. At the time, he was still a powerful and determined force within the labor movement. Over half a century later, his baffling disappearance remains one of the most enduring unsolved mysteries in American history.

In today's episode, we're heading to Somerton Beach in Adelaide, Australia, where a man was found dead in 1948 — with no ID, and labels cut from his clothes. Police found a small scrap of paper with the words “Tamám Shud" in a hidden pocket of his clothing. It was torn from a copy of the Persian poetry book Rubáiyát of Omar Khayyám. Although the phrase means "it is finished," for investigators, the mystery was just beginning.

In today's episode, we’re traveling back to the spring of 2001, when the disappearance of a young federal intern named Chandra Levy in Washington, D.C., became a national obsession. It was a story that unfolded in layers — part missing person investigation, part political scandal, and ultimately, an unsolved homicide that still raises the same haunting questions it did more than two decades ago.
