Unexplained mysteries never fail to pique our curiosity.

While supernatural events and conspiracy theories are fascinating, it's the murders and disappearances that are especially antagonizing. It's hard not to insist that someone out there knows the truth; that somebody holds the key that could bring any of these unexplained mysteries to light. After all, it's not unheard of for modern forensics to uncover elusive truths.

Yet, in some cases, despite all of our modern technology, some mysteries are still left unsolved. Take for example the case of the "Somerton Man," who was found dead and immaculately dressed on an Australian beach. While we have DNA and many clues were found, including a note in a secret pocket of his pants, the cold case remains frozen solid.

Episode 31: The Baffling Case Of The Somerton Man
In 1948, beachgoers came across a dead man on Australia's Somerton beach. Well-dressed and with no signs of trauma, police could determine neither his identity nor his cause of death — both of which remain a mystery to this day.

Then there's the case of tourists Kris Kremers and Lisanne Froon who vanished into a Panamanian jungle and seemingly died there. Although investigators found some of their remains, bags, and camera photos, the circumstances around the deaths remain baffling.

These twenty-five cold case murders, disappearances, scientific anomalies, and other discoveries are some of the most enduring in history and it's possible they may never be fully explained. For those who have lost family members and loved ones, it's a hard pill to swallow. But perhaps reading the details of some of these crimes and occurrences will spark a memory - one that could change the status of one these mysteries from unexplained to solved.
