THIS is the terrifying moment Grindr serial killer Stephen Port revealed his guilt in the murder of four men with seven telltale signs.
The monster raped and killed Anthony Walgate (23), Gabriel Kovari (22), Daniel Whitworth and Jack Taylor (25) after administering the knock-out drug GBH to them.
He then disposed of their bodies near his home in Barking, east London, between 2014 and 2015.
Port was sentenced to life imprisonment in 2016 for the murder and rape of three other men he drugged.
A new documentary has now revealed the telltale signs that Port showed and which show his guilt in the horror.
“The Grindr Killer Scandal: A Faking It Special” examines how the killer’s diabolical web of lies was exposed when he was questioned about Jack’s death.
Body language expert Dr Cliff Lansley said Port showed a high level of fear when officers asked him why he had searched for the “boy”, “drugged” him and “raped” him as the 25-year-old lay dying.
The monster tried to wiggle out of the interrogation by claiming he was “just generally looking for porn in general.”
But Dr Lansley explains: “Just look at his left arm. You can see his leg moving up and down. This is a time of great fear.”
“We have a hand clamp under the table, a diminutive of the word ‘only’ and a bilateral hand twitch.”
The expert also says that Port’s use of the word “only” is important because it is an attempt to claim that the searches he conducted were of no use.
But the show shows how the murderer’s shrug of the shoulders shows how little confidence he has in the statement.
Dr. Lansley identifies a total of seven telltale signs that Port is guilty – including the shrug of the shoulders and six slight shakes of the head that contradict the allegations.
The expert adds: “So with just seven seconds and just five words – ‘just search for random videos’ – we have seven clues to deception.”
“That’s definitely a lie.”
Later in the interview, Port is asked about Daniel’s death after he was discovered in a cemetery just 360 meters from the killer’s apartment.
You can see how his discomfort increases when he is shown a map of the location where the body was found and his home address.
Dr Lansley says: “We’re already getting a response from Port. It’s now approaching the ankle… if you look down here at the pants, you can see that vibration.”
“We call this a psychogenic tremor, and this tremor tries to release the accumulated energy in the large leg muscles, which were caused by the spike in fear when a picture of the crime scene, the churchyard surrounding the abbey, was presented.”
Port is also questioned about a so-called suicide note found on Daniel’s body, in which he himself is implicated in the murder of his co-victim Gabriel.
The expert says the psychogenic tremors continue as Port steps back about a foot from the table to get away from the “dirty evidence.”
Port carried out the gruesome rampage between 2014 and 2015 by attacking his victims on dating sites Apps.
Fundamental police errors allowed him to commit the murders and drug and sexually abuse more than a dozen other men.
It took more than a year for officials to finally link the deaths of all four men and arrest Port on suspicion of murder.
This development only came about when the grieving families of the victims were forced to conduct their own investigations.
An investigation had previously found that “fundamental failings” by the police probably contributed to the deaths of three of the men.
Currently, eight Met officers are under Investigation for gross misconduct.
Forensic psychologist Kerry Daynes says on the show: “If I were a family member of one of these boys, I would be absolutely furious.
“I would be devastated because these deaths could have been prevented. And there is nothing more painful than knowing that lives could have been saved but were not.”
