June 24, 1991. Boarhills, Scotland. The body of 33-year old Sandy Drummond is found on a farm track across the road from his cottage and it is determined that he was choked to death with what is described as a “ju-jitsu stranglehold”. In the days prior to his death, Sandy had suddenly quit his job without notice and withdrew nearly all of his money from his accounts, leading to speculation that someone may have been bullying or blackmailing him. Investigators explore a number of different leads, including eyewitness sightings of an orange car parked outside Sandy’s cottage before he was killed, but are unable to determine a clear-cut motive for the crime. On this week’s episode of “The Trail Went Cold”, we travel to Scotland to explore one of their most perplexing unsolved murders.

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”.

If you have any information about this case, please contact the Mercer County Homicide Task Force at (609) 989-6406.

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.
