In this episode, we discuss the I-44 Tri-State Truck Explosion. In September of 1970, the Tri-State trucking company and the Teamsters Local 823 Union were locked in a heated battle. Union truckers had been on strike for weeks, but their demands were being ignored. Instead, Tri-State had simply hired more non-union workers to fill the void. In retaliation, a few union drivers decided to set up along Interstate 44 near Springfield, Missouri to shoot and disable passing Tri-State rigs. However, one of those trucks was carrying 21 tons of dynamite, and what resulted was a catastrophic explosion that would end one innocent life and put three others in prison.

Episode 349 is part one of our two part series on one of the most infamous cases in all of true crime, and the basis for Truman Capote's legendary book "In Cold Blood" - the Clutter family murders. The Clutters were a prominent farm family in rural Kansas and were respected and revered by everyone in their tiny community.  Then, on a chilly November night in 1959, someone broke into the Clutter's home and murdered everyone inside. Barely anything was taken, so robbery wasn't thought to be a motive. But if not, who killed the Clutters, and why?
