The desperate screams of a man as he was stabbed to death in his bedroom during an extreme sex session with his porn actor lover were played to a jury today.
Yostin Andres Mosquera is accused of murdering Albert Alfonso, 62, and Paul Longworth, 71, in the flat the civil partners shared in Shepherd’s Bush, west London, last July.
Mosquera, 35, has admitted the manslaughter of Mr Alfonso but denies two charges of murder.
Prosecutor Deanna Heer KC previously told jurors at the Old Bailey Mosquera ‘could hardly deny’ killing Mr Alfonso, telling the jury the attack took place while they were having sex.
Both the sex and the killing were filmed, she said.
Mosquera then ‘decapitated and dismembered’ the couple, freezing some body parts and taking the rest of their remains in suitcases to the Clifton Suspension Bridge in Bristol, jurors have heard.
The footage was deemed too gruesome to be played in court, but jurors were able to listen to audio from it while a police officer narrated what it showed.

PC Nick Swire described the ‘frenzied stabbing’, with Mr Alfonso crying out in pain as blood seeps down his chest.
Ms Heer said: ‘They then fall onto the floor where Mr Mosquera is able to get on top of Mr Alfonso, Mosquera is heard to shout in English “You like it?”
‘Mr Mosquera is seen to stab him multiple times in the chest area.’
PC Swire said: ‘From my view I see the right hand of Mosquera applying the knife to the throat area of Mr Alfonso, and blood is seen to flow down the chest, this is the point of incision.’
Jurors heard Mr Alfonso tried to fight off Mosquera, described in court as a ‘pornographic performer’, but he was unable to do so and can be seen eventually losing consciousness.
Mr Alfonso’s body can be seen going limp on the floor, when Mosquera begins to sing and dance.
He places Mr Alfonso on a plastic sheet, before heading straight to the computer in the bedroom.
Ms Heer asked: ‘Do you hear a change in the sound of his (Mr Alfonso’s) breathing from this point on?’
‘Yes,’ the officer replied.
‘His body goes limp, he loses consciousness.’
Mr Longworth had likely already been killed by Mosquera with hammer blows to the back of the head before the sex session, the jury heard.

Yesterday, the court heard that two days later a cyclist on the Clifton Suspension Bridge in Bristol saw Mosquera standing next to a large red suitcase and asked if he was OK.
The witness also spotted a large silver trunk a few yards away. Mosquera told him that the luggage contained car parts, jurors heard.
But inside were the dismembered bodies of the victims which Mosquera had transported from their home, Ms Heer said. The rest of their remains were found in a chest freezer in their flat.
Mosquera’s actions were ‘planned and premeditated and, having killed them, he immediately set about trying to steal from them’, she told the court.
The trial continues.
