Colombian Porn Actor Guilty of Murdering Couple, Dumping Remains on Clifton Bridge
On July 21, 2025, Yostin Andres Mosquera, a 35-year-old Colombian adult film actor, was found guilty of murdering civil partners Albert Alfonso, 62, and Paul Longworth, 71, at their Scotts Road flat in Shepherd’s Bush, west London, on July 8, 2024.
Mosquera bludgeoned Longworth with a hammer between 12:30 p.m. and 1:00 p.m., shattering his skull, and hid his body in a divan bed. Hours later, he stabbed Alfonso repeatedly during a recorded sexual encounter, slitting his throat. “What is striking, when one considers the footage, is just how calm and in control the defendant remains throughout,” said prosecutor Deanna Heer, KC. Jurors at Woolwich Crown Court viewed the distressing footage, which showed Mosquera singing and dancing after Alfonso’s death.
Mosquera dismembered both victims, placing their heads in a chest freezer and other remains in two suitcases – a red suitcase and a silver trunk. On July 10, 2024, he hired a van driver to transport him from London to Bristol, intending to dispose of the suitcases at Clifton Suspension Bridge. At 11:30 p.m., cyclist Douglas Cunningham spotted Mosquera with the leaking suitcases, mistaking him for a lost tourist. Mosquera claimed they contained car parts, but police later found the victims’ remains, with a tag on the trunk linking back to Scotts Road. “In fact, the suitcases contained the decapitated and dismembered bodies of Paul Longworth and Albert Alfonso,” Heer stated.
Mosquera met Alfonso online via webcam sex websites, using aliases like ‘iamblackmaster’ and ‘mrd-k20cm.’ He visited the couple in October 2023, and they traveled to Colombia in March 2024.
In June 2024, Mosquera returned to the UK for English lessons and financial support from Alfonso, engaging in paid sexual acts that Alfonso filmed and posted online. Prosecutors revealed Mosquera accessed Alfonso’s bank accounts post-murder, withdrawing cash and researching the couple’s flat value to “steal” from them. “The prosecution case is that the defendant murdered both men, that his actions were planned and premeditated,” Heer said.
Mosquera claimed Alfonso killed Longworth and that he stabbed Alfonso in self-defense, fearing for his life. “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,” he testified. He also alleged daily rape by Alfonso, feeling “humiliated, sad and trapped,” but Heer noted his defense statement omitted these claims.
The jury, deliberating for five hours and three minutes, rejected his manslaughter plea for Alfonso and unanimously convicted him of both murders. Mr Justice Bennathan, KC, stated, “I am not going to pass sentence on you today. The only sentence I can pass is one of life imprisonment,” ordering psychiatric reports for sentencing on October 24, 2025.
