September 2, 1959. Seattle, Washington. 62-year old Pearl Kongsle discovers a paper sack on the walkway outside her residence and when she bends over to pick it up, a bomb goes off and kills her. Even though a car containing three teenage boys is seen speeding away from the scene following the blast, investigators are unable to turn up any major leads or compelling suspects with a motive to harm Pearl. It turns out that months earlier, two relatives of Pearl’s late husband died after a mysterious poisoning and there was another strange incident where sticks of dynamite were discovered on the property of Pearl’s brother-in-law, but no link can be found between these events and Pearl’s murder. On this week’s episode of “The Trail Went Cold”, we explore the bizarre unsolved bombing death of Pearl Kongsle.

August 7, 1996. Travis County, Texas. After running errands with her family, six-year old Katherine Korzilius is dropped off at a community mailbox in her neighbourhood and is last seen walking in the direction of her home. Fifteen minutes later, Katherine’s mother discovers her body lying in the road about a quarter-mile away from their residence. An autopsy reveals that she has a fractured skull, so the medical examiner concludes that Katherine was likely thrown or fell from a moving vehicle. While investigators suspect that Katherine may have grabbed onto the back of her mother’s SUV as it drove away before she fell off, her family believes she was murdered by an unknown party in a botched abduction attempt. On this week’s episode of “The Trail Went Cold”, we explore the tragic unexplained death of Katherine Korzilius.
