    EP134: The Serial Killer Next Door: Joel Rifkin (Part 1)
    Jul 16 2025
    Join our Patreon family for exclusive bonus content, access to BTS, a private group chat, merch discounts, and to guest co-host with Investigator Slater! www.Patreon.com/PsychopediaPod Inspired by Gary Ridgway and Ted Bundy, serial killer Joel Rifin modeled his victimology and body disposable methods like a grotesque homage: limbs in cement, heads in paint cans, bodies dumped with calculated precision. For four years in the late 1980s/early 90s, while living with his mother in the heart of suburban Long Island, NY, Joel Rifkin hunted women on the margins. Joel, a bullied outcast with a high IQ and a severely damaged frontal lobe, didn’t explode overnight. He eroded. First came the fantasies. Then came the reality of 17 victims whom he strangled and dismembered with an X-Acto knife. Joel blended in — just another quiet man with a sedan, a part time job, and a taste for sadism. This wasn’t some obvious "monster" lurking in the shadows. This was a depraved serial killer next door, hiding in plain sight, mowing the same lawns your kids play on. Welcome to Part 1 of New York’s most known prolific killer: Joel Rifkin, aka Joel The Ripper.

    EP133: TikTok Execution: Killed On Camera
    Jul 9 2025
    Join our Patreon family to guest co-host with Investigator Slater! Also gain exclusive access to BTS, bonus true crime episodes, a private group chat, merch discounts, and much more! www.Patreon.com/PsychopediaPod On May 13, 2025, 22-year-old influencer Valeria Márquez was executed on TikTok livestream — shot point-blank by a man disguised as a delivery driver inside her own beauty salon in Zapopan, Jalisco, Mexico. Viewers watched in horror as she clutched her chest and stomach before collapsing, still holding a stuffed animal as she perished on camera. Horrifyingly, the video footage went viral, and the calculated nature of the hit left Mexico (and the rest of the world) stunned. Investigators are continuing to explore whether the murder was cartel-related, a personal betrayal, or both. Rumors point to a possible setup by an employee or even Valeria’s best friend, who allegedly urged Valeria to stay at the salon just as the killer arrived. The most widespread theory, however, ties Valeria’s death to her ex-boyfriend, Ricardo Ruiz Velazco (aka “Doble R”), a high-ranking member of the Cartel Jalisco Nueva Generación (CJNG) cartel. One thing is certain: her execution was not random. Valeria’s murder now stands as a devastating emblem of Mexico’s brutal crossroads - where femicide, cartel violence, and institutional failure collide with devastating consequences.

A friend recommended this podcast to me a few weeks ago...finally decided to listen on my 1hr commute home at 2am in the morning. Rocked my socks! Perfect mix of "Haha" and "Oh, shit!" Love that they cover the grit of the cases. Brooke and Tanks chemistry and history between one another is awesome and genuine! Racing to get through more episodes.

Love it already

Absolutely binge worthy. I love this podcast. I'm an avid true crime fanatic. Normally, I would have to take breaks from the constant "doom & gloom". However, Tank brings his well informed levity while Investigator Slayer drops her wicked case bombs with her intellectually vicious rhetoric. The combination is refreshing. entertaining and hilarious. It means I NEVER have to stop listening. EVER. Keep it up. You guys ring my bell every time!

Feed me. F*ck me. Psychopedia me.

I am hooked line and sinker. all caught up on content. need more.
Slater voice delivers. Tank I relate to you on so many levels.
thank you.

little side not for Tank. I recently had a friend say to me she thinks I could drink (sober 2 years now and I am the best version of my self!) I went along with what she was saying. then later she tried passing me her drink. I had to ask "is this alcohol? " i almost just grabbed and sipped outta reflects. but it hit me she didn't understand... and I replayed your conversation with investigator Slater. where she didn't understand. But new you and your struggle. this moment comforted me and kept me on a path that some drinkers just can't fathom. it won't stop there and there isn't enough booze once activated.

so thank you.
You are a key element to. this podcast. Tank love you
