Yostin Andres Mosquera has been convicted of murdering and dismembering a London couple before attempting to dispose of their body parts at the Clifton Suspension Bridge. The 35-year-old Colombian national decapitated Albert Alfonso, 62, and Paul Longworth, 71, at their home in Shepherd’s Bush, west London, on 8 July 2024.
The case came to light on the evening of 10 July 2024, when a passer-by spotted Mosquera struggling with a suitcase near the Mall pub in Clifton, Bristol. The following morning, police closed the Clifton Suspension Bridge after discovering human remains inside the suitcase. Avon and Somerset Police confirmed the find, sparking a major investigation.
Mosquera was arrested two days later after a cyclist confronted him in Leigh Woods. The suspect fled, reportedly saying in Spanish: “My boss is a bad man.” However, the motive was far more personal. Prosecutors revealed that Mosquera had met Alfonso via webcam sites in 2012 and had visited the couple in Colombia in 2022 and 2024.
During the trial at the Old Bailey, it emerged that Mosquera killed Alfonso while filming the act, and then attacked Longworth with a hammer. He later searched online for the value of the couple’s home, looked for a chest freezer, and researched serial killers. After dismembering the bodies, he placed the heads in a freezer and transported the rest to Bristol.
Mosquera claimed he acted in self-defence, alleging that Alfonso had killed Longworth and that he feared for his own life. However, the jury rejected his account. Detective Chief Inspector Ollie Stride of the Metropolitan Police described the case as “one of the most harrowing murders” his team had ever investigated.
