Yostin Andres Mosquera, a Colombian national, has been convicted of murdering and dismembering a London couple before attempting to dispose of their body parts at the Clifton Suspension Bridge in Bristol. The case, described by the Metropolitan Police as one of its 'most harrowing' inquiries, shocked the nation after a suitcase containing human remains was found on the iconic bridge on 11 July 2024.
The victims, Albert Alfonso, 62, and Paul Longworth, 71, were in a civil partnership and lived in Shepherd's Bush, west London. Mosquera, who met Alfonso via webcam sites in 2012, had stayed with the couple before killing them on 8 July 2024. Alfonso was stabbed to death during a recorded sexual encounter, while Longworth was attacked with a hammer, suffering repeated blows to the head.
After the murders, Mosquera used Alfonso's computer to access banking information, attempted to transfer £4,000 to his own account in Colombia, and searched online for items such as a chest freezer and information on serial killers. He then dismembered the bodies, placing the heads in a freezer before transporting the remains in a suitcase to Bristol.
The discovery occurred when two men were seen grappling with a suitcase near the Clifton Suspension Bridge. One of them, Mosquera, fled the scene. A cyclist confronted him, and video footage showed the suspect claiming in Spanish, 'My boss is a bad man.' Mosquera was arrested two days later.
During the trial at the Old Bailey, Mosquera claimed that Alfonso had killed Longworth and that he acted in self-defence when stabbing Alfonso. However, the jury rejected his account, and he was found guilty of both murders. Detective Chief Inspector Ollie Stride of the Metropolitan Police described the case as 'one of the most harrowing murders' his team had ever investigated.
