Modus Operandi - Drugging

Stephen Port, widely referred to as the Grindr Killer, was a British serial killer who targeted young men he met through online dating platforms, particularly Grindr. Operating in London between 2014 and 2015, he used deception to lure victims to his home, where he drugged them with lethal doses of GHB before sexually assaulting and murdering them. Port’s crimes were marked by manipulation and calculated staging, often disposing of victims’ bodies in or near public areas and attempting to mislead police by planting false evidence. His actions exposed serious investigative failures by authorities, as opportunities to stop him earlier were missed. He was eventually arrested, convicted, and sentenced to life imprisonment.

Jason Marshall is a British serial killer who murdered Peter Fasoli in London before fleeing to Italy, where he murdered Vincenzo Iale and attempted to murder another man within weeks. Marshall used deception, impersonating a police officer or intelligence agent to gain his victims' trust before robbing and killing them. Convicted in both Italy and the United Kingdom, he is serving a life sentence with a minimum term of 39 years.
