On January 24th, 1969, one of Gregg County, Texas’s most cold-blooded and savage murders occurred: that of 17-year-old Longview High School senior Leslye Dian Koon. The slaying prompted one of the city’s most extensive and intensive investigations in its history. What you might call a taskforce was created that included the Gregg County Sheriff’s Office, the District Attorney’s Office, and Longview Police Detectives, who were on loan out of their jurisdiction. Upon the discovery of a life insurance policy in Leslye’s name, the District Attorney identified three suspects who were charged, indicted, and tried for the murder. But the case remains unsolved to this day – and hasn’t been mentioned since.<br /><br />If you have any information about the 1969 murder of Leslye Dian Koon, please contact Gregg County Crime Stoppers at 903-236-STOP.<br /><br />You can support gone cold and listen to the show ad-free at https://patreon.com/gonecoldpodcast Find us at <a href="https://www.gonecold.com" target="_blank" rel="noreferrer noopener">https://www.gonecold.com</a><br /><br />For Gone Cold merch, visit <a href="https://gonecold.dashery.com" target="_blank" rel="noreferrer noopener">https://gonecold.dashery.com</a><br /><br />Follow gone cold on Facebook, Instagram, Threads, TikTok, YouTube, and X.
