September 4, 1977. Ewing Township, New Jersey. The nude body of 25-year old graduate student Sigrid Stevenson is discovered beneath a piano cover inside the Main Stage Theater of Kendall Hall on the campus of Trenton State College. She has been bludgeoned to death with a blunt object and since Sigrid had been staying in Kendall Hall that weekend, she was likely attacked while practicing the piano on stage. A number of people are looked at as potential suspects, including campus police officers, campus staff and members of a theatre group, but there is no conclusive evidence to implicate any of them and Sigrid’s murder remains unsolved. On this week’s episode of “The Trail Went Cold”, we explore a cold case that was recently featured on the Netflix reboot of “Unsolved Mysteries”.

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.

October 11, 1991. Bolney, England. The dismembered torso of a male homicide victim which has been rolled up in some carpet is discovered in a wooded area next to a bridle path. His head and both of his hands have been removed and since the victim cannot be identified, he is buried under the name “Unknown Male”. Investigators explore a number of different leads, including a wanted German fraudster who was living in the area at the time the torso was discovered, as well as the possibility that the victim’s death was a gangland killing, but the crime is never solved. On this week’s episode of “The Trail Went Cold”, we travel back to the United Kingdom to explore the bizarre story of an unidentified decedent known only as “The Bolney Torso”.

October 24, 1998. Brooklyn, New York. 28-year old Kristine Kupka, who happens to be five months’ pregnant, is seen leaving her residence alongside the father of her child, Darshanand “Rudy” Persaud. Kristine never returns, but even though Rudy claims that he took her to a shopping mall and dropped her off a few blocks from her home, his story cannot be corroborated. It turns out that Rudy was married to another woman and had asked Kristine to get an abortion for fear that the revelation about her pregnancy would ruin his life. Even though a cloud of suspicion surrounds Rudy, there is no evidence to implicate him in Kristine’s disappearance and no trace of her is ever found. On this week’s episode of “The Trail Went Cold”, we explore a missing persons case involving a pregnant woman which has gone unsolved for over 26 years.
