A Colombian porn actor has today been found guilty of murdering a couple and dumping their dismembered bodies in suitcases on Clifton Suspension Bridge.
Yostin Andres Mosquera, 35, repeatedly stabbed Alberto Alfonso, 62, and slit his throat during a recorded sex session just hours after bludgeoning his partner Paul Longworth, 71, over the head with a hammer on July 8 last year.
As Mr Alfonso bled out on the floor, the naked murderer started singing and dancing before he made his way to his victims’ computer, accessing his bank account online and withdrawing cash with his card in the early hours of the morning.
In a bid to cover his tracks, he decapitated them and hid their heads in a chest freezer at their house in Scotts Road, Shepherd’s Bush, west London, where he had been staying with them.
The trial heard how two days later, Mosquera hired a man with a van who unwittingly drove him from London to Bristol so he could dump a suitcase and a trunk containing their chopped-up bodies at Clifton Suspension Bridge.
The grisly deaths were first discovered when the luggage was found on the iconic bridge at 11.30pm on July 10 last year. The silver trunk had a tag on it linking them back to an address on Scotts Road where police found the heads in the freezer.
At Woolwich Crown Court today, Mosquera was found guilty of both murders after jurors deliberated for five hours and three minutes.
Mosquera, a Colombian national, met Mr Alfonso online through webcam sex websites and used the names ‘iamblackmaster and ‘mrd—k20cm’, but later set about trying to steal from him.

The court heard Mr Alfonso liked ‘extreme sex’, which Mr Longworth, who knew and accepted it, had ‘nothing to do with’.
Mosquera first visited the couple in London in October 2023 and the couple travelled to Colombia in March 2024. He returned to England last June on the promise of English lessons and financial support from Mr Alfonso.
The court heard how he also participated in sex acts and dominated and degraded Mr Alfonso who filmed it and posted the footage online. He was in a paid sexual relationship with Mr Alfonso.
Prosecutors told the trial how Mr Alfonso, a swimming instructor at Mode Gym in Acton, and Mr Longworth, a retired handyman, were in a happy long-term relationship when they were barbarically murdered by Mosquera.
Mr Longworth is believed to have been killed by multiple blows to the head with a hammer between 12.30pm and 1pm on July 8 last year when Mosquera was seen closing curtains to a first floor window on CCTV.
Mosquera shattered Mr Longworth’s skull before hiding his body in a divan bed, the court heard. He later cut his corpse up with a power tool and knife and stuffed it in a suitcase.
Later that day, Mr Alfonso was stabbed to death after he and Mosquera were recording themselves having sex. Jurors were shown the distressing footage of Mr Alfonso being killed on camera before Mosquera danced and sang afterwards.
Mr Alfonso was in a ‘submissive’ role and referred to Mosquera as ‘master’ during the recorded session.
‘What is striking, when one considers the footage, is just how calm and in control the defendant remains throughout’, prosecutor Deanna Heer, KC, told the trial.
On the day that the two men were killed Mosquera googled ‘Where on the head is a knock fatal?’ and ‘How long before a corpse starts to decompose?’
‘The post mortem examination of his body revealed that he had suffered severe blunt force trauma to the head which caused his death’, said Ms Heer.

She explained that there were injuries on her hand, which suggested that he had tried to defend himself.
‘When the flat was later searched, a hammer was found lying on the floor in the hallway. It was found to be stained with Paul Longworth’s blood’, she said.
Earlier in his evidence, Mosquera claimed Mr Alfonso cut up Mr Longworth’s body after killing him.
He said he stabbed Mr Alfonso because he was ‘afraid that he would do the same to me that he had done to Paul’.
Mosquera said after seeing Mr Longworth’s dismembered body, he decided to do the same to Mr Alfonso’s corpse.
‘Yes I saw Paul’s body and I cut Albert’s. I don’t know the exact moment but I cut it having seen Paul’s body’.
The trial heard how Mosquera was interrupted by a man while he was attempting to dispose of the suitcases on Clifton Suspension Bridge.
Prosecutor Ms Heer, KC, said: ‘At about 11.30pm on the night of the 10 July 2024 Douglas Cunningham was cycling home across the Clifton Suspension Bridge in Bristol when he saw the defendant, Yostin Mosquera, standing next to a large red suitcase.

July 8: CCTV shows Mosquera looking out of the window at 12.30pm, drawing the curtains. They remained closed until about 1pm when he opened them again, which prosecutors suggested was the time Mr Longworth was killed.
July 8: Later that day, at 7.21pm, Mosquera and Mr Alfonso are seen walking into the house after an outing. At this point, Mr Longworth is believed to already be dead

‘Thinking he was a lost tourist, Mr Cunningham stopped to see if he was okay.
‘A few metres away from where the defendant was standing, on the bridge approach, there was another suitcase, a large silver trunk.
‘The defendant told Mr Cunningham that he was from Colombia and that the suitcase he was standing with contained car parts. That was a lie.
‘In fact, the suitcases contained the decapitated and dismembered bodies of Paul Longworth and Albert Alfonso, which the defendant had taken to Bristol from their home in London where they had been killed two days before.’
The trial heard how Mosquera was visiting Mr Alfonso at the time of the killings, having returned to the UK to stay with the couple on June 9 2024.
On June 29 2024, Mr Alfonso and Mr Longworth took Mosquera to Brighton for the day, with photos showing them at Brighton pier, drinking beer and going on a zip wire.
They also engaged in sex sessions along with another man, known by pseudonym James Smith in the trial.
But on July 8 last year, Mosquera hatched his plan to kill Mr Longworth and Mr Alfonso before attempting to cover-up their deaths.
Mosquera had denied both murderers and sought to blame Mr Alfonso for killing Mr Longworth.

But the prosecution’s case was that Mr Alfonso did not know and that he was out of the flat at work at the time Mr Longworth was killed and that Mosquera hid the body before he returned.
The court heard that Mosquera had also got hold of Mr Alfonso’s financial information, copying over spreadsheets containing his bank details relating to Barclays, Halifax, Natwest, Moneygram and Paypal on June 27.
Prosecutors told the court this was to ‘steal’ money from Mr Alfonso. On July 8 last year, the day of the murders, Mosquera also looked up the value of the Scotts Road flat in a bid to ‘find out what they [the couple] were worth’.
Mosquera claimed during the trial that he feared for his own life and believed he was about to be killed when he stabbed Mr Alfonso.
He also said he was ‘raped every day’ by Mr Alfonso, telling jurors it made him feel ‘humiliated, sad and trapped’, but never angry.
But prosecutor Ms Heer KC reminded the court that his ‘detailed’ defence statement produced for trial made no mention of the alleged rape.
The case was put to a retrial after incorrect evidence was placed before the jury.
Mr Justice Bennathan told Mosquera, aided in the dock by an interpreter, today: ‘I am not going to pass sentence on you today. The only sentence I can pass is one of life imprisonment.’
The judge ordered psychiatric reports and adjourned sentence until 24 October.
Mr Justice Bennathan also thanked the jurors who had to view the horrific footage repeatedly throughout trial.
