Stephen Port, 41, is accused of spiking young men with GHB — known as “liquid ecstasy” — so he could fulfil sexual fetishes of having sex with their unconscious bodies.
Four of his alleged victims — Anthony Walgate, 23, Gabriel Kovari, 22, Daniel Whitworth, 21, and Jack Taylor, 25 – died from drug overdoses.
Today, jurors at the Old Bailey were shown photos of the inside of Port”s one-bedroom flat in Barking, east London.
His home was searched by cops following the death of his first alleged murder victim, Anthony Walgate, 23.
Among the items pictured during the search on 27 June, 2014, was a pair of underpants with “Born 4 Porn” stamped across them.
Police also found a bottle of Amsterdam Gold poppers on his table and another in the fridge, as well as an empty bottle of baby oil.
A bedroom drawer also contained a dildo, condoms, lubricant and porn DVDs were in his living room cabinet, the court heard.
Port pleaded guilty to perverting the course of justice over Mr Walgate”s death and was sentenced to eight months in prison on March 23, 2016.
But by the time he was jailed, Port had allegedly killed two more young men.
Slovakian Gabriel Kovari, 22, and 21-year-old chef Daniel Whitworth died within weeks of each other in August and September 2014.
Both – like Mr Walgate – had died of GHB poisoning and were found in an almost identical position in St Margaret”s churchyard, in Abbey Green.
Port is said to have killed again just three months after being released from prison, in September 2015, when forklift truck driver Jack Taylor, 25, was found near the same churchyard.
He was arrested on October 15 last year when police again photographed his home.
Two days ago, the court was shown footage of Port allegedly raping an unconscious man in his flat.
Some jurors were visibly distressed by the 18-minute DVD.
