For Marius Gustavson, a Norwegian man in London, it began with self-castration. From there, his obsession metastasized into a full-blown operation whereby he performed extreme body modifications on dozens of vulnerable men. Marius filmed the mutilations and streamed them on a pay-per-view website, where he also sold severed genitalia to paying customers. His hunting ground was the “nullo” community, composed of individuals seeking genital removal as a radical form of body modification. Many struggled with Body Integrity Identity Disorder (BIID) and turned to Gustavson for help. Instead, they got mutilation, exploitation, and a predator who feasted on their vulnerability — sometimes literally - as Gustavson went on to cannibalize some of the very testicles he cut off. This case is almost too gruesome to believe. But, it isn’t just about mutilation: it’s about control, sadism, consent twisted into theater, and the terrifying lengths people will go to reshape themselves when the wrong hands hold the scalpel.

Please listen with caution. In June 2005, in the quiet town of Benejúzar, Spain, 51-year-old María del Carmen García walked into a bar, canister of gasoline in hand, and doused a 63-year-old man standing at the counter. Then, she struck a match. Eleven days later, the man was dead from his injuries — and María was hailed as a hero by thousands. Because years earlier, that same man had raped Maria's 13-year-old daughter at knifepoint, and now she was delivering her own brand of justice. To some, María was considered a dangerous criminal guilty of first degree murder who crossed an unforgivable line by taking a human life. To others, she was a mother pushed past her breaking point, and an admirable vigilante stepping in where the system had failed. To this day, this shocking case remains one of Spain’s most fiercely debated examples of vigilantism and continues to force uncomfortable questions about the morality of vigilantism and when, or if, taking the law into your own hands is ever justified.

This is such a great listen. The crimes discussed on this show are absolutely fascinating and also jaw dropping to say the least. Just when you think its too heavy to continue listening the TANK SINTRA drops a line that makes you laugh and giggle out loud helping to lighten the load. Investigater Slater does an amazing job researching and delivering these disspicable crimes. Amazing 👏
