  • OBSESSED

    I listen to a lot of true crime… possibly too much. I don’t say this lightly. Psychopedia is my absolute favorite podcast. Investigator Slater is a phenomenal researcher and story teller! Even on the cases I’ve heard on other podcasts I learn something new. She’s compassionate, funny, easy to listen to and absolutely amazing at what she does. I’m sad I already binged all of the back catalog so please excuse me while I sign up to become a Semen Demon IYKYK.

    Miss tank to bring back opposing views. She’s too political and too self involved. Hard pass.

  • Like the crack I didn’t know I needed.

    I have never been a true crime podcast junkie. Typically stick to sports and news. Ran across Investigator Slater on Insta and decided to try an episode. After listening to a few. I went back and binged from the beginning listening to 2 a day most days. It has been 6 days since the last episode dropped and I need another hit. A case I would love to see her cover is Herb Baumeister.
