    EP185: Mormon Sex in Chains: Joyce McKinney
    May 27 2026
    Few cases in modern tabloid history are as bizarre, twisted, and jaw-dropping as the story of Joyce McKinney — the former beauty queen, ex-Mormon, and alleged “love-obsessed” woman accused of flying across the world, handcuffing her ex-lover to a bed in rural England, and forcing him into what the British press dubbed “sex in chains.” But beneath the campy headlines and late-1970s media circus was something far darker and stranger: a disturbed woman who insisted she was rescuing the man she loved from a religious cult, a kidnapped Mormon missionary who was tortured and sexually assaulted for three days, tabloid hysteria, countless aliases, fugitive drama, and a case so outrageous it blurs the line between true crime, psychological obsession, and a full-blown fever dream.

  • EP184: Waffle House Massacre: The Taylor Swift-Obsessed Shooter

    EP184: Waffle House Massacre: The Taylor Swift-Obsessed Shooter
    May 20 2026
    On April 22, 2018, a partially naked young man named Travis Reinking opened fire with an AR-15 rifle at a Waffle House in Antioch, Tennessee, killing four innocent people and injuring others. He had a documented history of erratic behavior, including delusions that Taylor Swift was stalking him, as well as a 2017 arrest in Washington, D.C., after attempting to breach White House security. That incident led to his arrest and the confiscation of his firearms, weapons that were later returned to his father and ultimately given back to him. This devastating case is not just about the horror of that night, but about the warning signs that preceded it, and the dangerous intersection of mental illness, access to assault-style weapons, and systemic failure.

I saw this title and the two hosts and I admit that I thought oh this is a 'Joe Rogan does true crime' right wing podcast. I was ABSOLUTELY proved wrong almost instantly as the intelligently researched crime stories, expertly delivered by investigator Slater and interjected with thoughtful, considered and empathetic remarks from the admittedly 'jacked' Tank Sinatra. That's not to say there isn't humour and 'in jokes' that when you know, you know. Tanks love of hip hop and obviously meme culture comes through in the episodes. Brooke Slater (an actual investigator in her day job working with human trafficking among other things) has a real knack for researching all the key elements of a case and humanising victims as well as her 'pop quizzes' that she posits to Tank and the listener which is a novel feature i personally love. overall an excellent True Crime podcast that only gets better as it goes on and I think will shine through as one of the top of it's genre. Crimedy Chaos Completed supremely.

It is a doozy, great true crime comedy cohorts.
