A Colombian porn artist danced and sang moments after murdering his lover and partner in a gruesome double killing before attempting to dump their dismembered remains off the Clifton Suspension Bridge, the Old Bailey has heard.
Yostin Andres Mosquera, 35, is accused of murdering 71-year-old Paul Longworth and 62-year-old Albert Alfonso at their home in Shepherd’s Bush, west London, in a calculated attempt to steal their savings and sell their property.
Jurors were told how Mosquera, who was in a paid sexual relationship with Mr Alfonso, bludgeoned Mr Longworth with a hammer before stabbing and slitting Mr Alfonso’s throat during a filmed sex act. Both men were later decapitated and dismembered, with their remains packed into suitcases.
On the night of 10 July 2024, cyclist Douglas Cunningham spotted Mosquera loitering beside a large red suitcase on the Clifton Suspension Bridge. Mistaking him for a lost tourist, Mr Cunningham stopped to assist, only to be told the luggage contained “car parts”. A second suitcase—a large silver trunk—stood nearby. Both, in fact, held the mutilated bodies of the murdered couple.
Prosecutor Deanna Heer KC told the court that the heads of both victims were later found in a chest freezer at their flat in Scotts Road, along with other body parts. Blood-stained evidence, including the murder weapon—a hammer—was recovered from the property.
Ms Heer revealed to jurors that Mosquera had calmly danced and sang after killing Mr Alfonso, before heading to his computer—still naked—to attempt to access his victim’s bank accounts. A spreadsheet containing the couple’s financial information had been created, and online activity showed searches for the value of their home, poisonings, serial killers, and Jack the Ripper.
Mosquera, who denies murder but admits manslaughter in the case of Mr Alfonso, allegedly plotted to steal from the couple and escape to Colombia. He tried transferring £4,000 to his own account and withdrew £900 in multiple transactions before the banks blocked further access.
The court was shown evidence that Mosquera messaged Mr Alfonso’s employer after the killing, pretending to be the deceased and claiming he had flown to Costa Rica due to a family emergency.
Jurors were warned they would have to view footage of Mr Alfonso’s final moments, filmed during a sexual encounter in which he referred to Mosquera as “master” and took a submissive role. The footage shows Mosquera removing a knife hidden under a black cloth and using it to stab Mr Alfonso during a prolonged and bloody struggle.
Despite the horror of what he had just done, Mosquera appeared calm and in control, prosecutors said. He sang aloud and even performed a dance over Mr Alfonso’s dying body before walking to the desktop computer.

The court also heard from a witness referred to as “James Smith”, who claimed he had been paid by Mr Alfonso for degrading sex acts. Mr Longworth, a retired handyman, did not appear to be sexually involved with Mr Alfonso but tolerated his partner’s activities.
Mosquera is believed to have first met Mr Alfonso online in 2017. He operated under the usernames “Iamblackmaster” and “MrDick20cm”, and sent explicit content—including a video of him dressed as Father Christmas—to his lover. The pair reunited in Colombia earlier this year during a holiday with Mr Longworth.
Returning to the UK in June, Mosquera moved into the couple’s flat, allegedly under the pretence of friendship but with a sinister motive. Jurors heard how he secretly researched “fatal head injuries”, “house prices in Shepherd’s Bush”, and shopped for a chest freezer on Facebook Marketplace.
Mosquera was arrested in the early hours of 13 July on a bench outside Bristol Temple Meads station. By then, police had found the grisly contents of the suitcases and traced the address on one of the labels.
He remains in custody, charged with two counts of murder, and the trial continues.
