Chilling moment naked porn star dances covered in victims' blood after double killing

Harrowing footage shows a killer singing and dancing naked in the aftermath of a brutal attack on a couple he had just butchered.

Yostin Andres Mosquera was covered in the blood of civil partners Albert Alfonso, 62, and Paul Longworth, 71, who he murdered in July 8 last year in their flat in Shepherd’s Bush, west London. He was this week found guilty of killing he men, before decapitating them and dumping their bodies in a suitcase on Clifton Suspension Bridge.

Sick Mosquera is seen joyfully dancing around with no clothes on having been captured on a camera set up to record a sex session. The adult entertainer was staying with the couple and tried to access their bank details on their laptop after dismembered the men, stuffing their heads in a freezer and travelling to Bristol to try and get rid of the evidence, a court heard.

Woolwich Crown Court heard Mr Alfonso was repeatedly stabbed, suffering injuries to his torso, face and neck, while Mr Longworth was attacked with a hammer to the back of his head and his skull shattered. During a retrial, jurors heard Mr Alfonso enjoyed “extreme sex” and Mosquera, a Colombian national who did not speak English and whom he met online years earlier, was part of that world, jurors heard.

His actions after stabbing Mr Alfonso, including singing and dancing, could have been an outburst as he had been overwhelmed by all that had happened to him, his defence counsel suggested. Mosquera’s plan was to hurl the suitcases over the bridge to dispose of the remains after the “calculated” and “premeditated” killings, prosecutor Deanna Heer KC said.

He admitted killing Mr Alfonso but claims it was manslaughter by reason of loss of control. He had pleaded not guilty to murdering both men and insists Mr Alfonso killed Mr Longworth. He told the jury he feared for his own life and believed he was about to be killed when he stabbed Mr Alfonso.

The defendant claims that he thought Mr Alfonso would do to him what he claims he had already done to Mr Longworth, he felt “intimidated” and threats had been made to his family in Colombia. The court previously heard that computer searches for the phrase “where on the head is a knock fatal?” were made on the day the two men died.

It was suggested that Mosquera made repeated computer searches to find a freezer in the build-up to the killings. Many of the searches were in Spanish, some used Google translate and were also made while Mosquera was the only person in the house, the jury heard.

He asked questions about delivery options and several searches were looking for a deep freezer, a chest freezer, a large indoor and outdoor freezer for sale. In the days before the killings the phrase “hammer killer” was also tapped into the computer. The court also heard that Mosquera had first come to the UK from Colombia in June 2024 on the promise of English lessons and financial support from Mr Alfonso, whom he had met years earlier through webcam sex websites.

Detective Chief Inspector Ollie Stride, from the Met’s Specialist Crime Command who led this investigation, said: “This has been one of the most harrowing murders my team have ever investigated, a case that will stay with many of us for a long time. Paul and Albert were murdered in the most brutal and callous of ways in their own home. The investigation has been complex and intense and we worked tirelessly to build a catalogue of evidence which would ensure we brought Mosquera to justice.

“The team have consumed hundreds hours of footage, including some of the utmost disturbing and graphic nature. Those images will stay with all of us for a very long time. We are grateful to all those who helped us build this investigation, including Avon and Somerset Police, who commenced the investigation and arrested Mosquera.

"As well as the many witnesses who provided detailed accounts of events which must have been extremely hard to share. We have also worked closely with the LGBT+ Independent Advisory Group and I am grateful for their support and the advice they have provided as they helped monitor the investigation.

“Paul and Albert had known one another for decades. They were in a loving, committed relationship and welcomed Mosquera into their home. They did not deserve to have their lives taken away from them in the most traumatising of circumstances. Our thoughts and prayers remain with Paul and Albert’s family and loved ones and all who knew them, as they continue to process the trauma of what happened.”
