41-year-old chef Stephen Port has been found guilty of killing four men between June 2014 and September 2015.
He was also convicted of four rapes, four assaults by penetration and ten counts of administering a substance with intent.
Port found the four men in London after plucking them off dating sites and dosing them with fatal amounts of GHB.
In a trial that began in October, Port plead not guilty to all charges.
Port’s victims included 23-year-old Anthony Patrick Walgate, whose body was found in June 2014; 22-year-old Gabriel Kovari, whose body was dumped near a cemetery in August 2014; 21-year-old Daniel Whitworth, whose body was discovered near the same cemetery as Kovari’s a month later; and 25-year-old Jack Taylor who was found murdered in September 2015.
Port met all four men online. After getting together, he offered them large amounts of GHB. GHB — which is sometimes referred to as liquid ecstasy, lollipops, or liquid E — is a narcotic sedative that often results in loss of consciousness.
At first, authorities didn’t think the murders were in related, leading many activists to sharply critique the police for failing to find a gay link to the crimes.
Human rights campaigner Peter Tatchell said: “While timely and commendable, this verdict is no compensation for the loss of four young gay men who had their lives, hopes and dreams cut short.”
Port will be sentenced on Friday, and almost certainly faces life imprisonment.
