Clifton Bridge Suitcase Killer: Colombian man Yostin Mosquera jailed for life after dismembering London couple
Yostin Mosquera sentenced to life for double murder
In one of the most gruesome murder cases to shock the UK, Yostin Andres Mosquera, a 35-year-old Colombian national, has been sentenced to life imprisonment for killing and dismembering two men, Albert Alfonso and Paul Longworth, before attempting to dispose of their remains in suitcases near the Clifton Suspension Bridge in Bristol.
The sentencing, delivered at Woolwich Crown Court, marks the end of what investigators described as “one of the most harrowing and disturbing murder inquiries” in recent British history.
How the Chilling Case of Yostin Mosquera Unfolded
Mosquera, who met his victim Albert Alfonso online in 2012, was invited to the UK after years of contact involving explicit exchanges and paid sexual videos. In 2023, Alfonso paid for Mosquera’s trip to London, where he stayed with Alfonso and his civil partner, Paul Longworth, at their flat in Shepherd’s Bush, west London.
By July 2024, Mosquera’s second visit turned deadly. He bludgeoned Longworth to death with a hammer before stabbing Alfonso multiple times during what prosecutors described as a “filmed extreme sex session.” He later decapitated and dismembered both men, freezing parts of their bodies and stuffing others into suitcases.
Suitcases of Horror: The Clifton Bridge Discovery
Two days after the murders, Mosquera was spotted near the Clifton Suspension Bridge dragging a large red suitcase and a silver trunk. Witnesses became suspicious after noticing fluid leaking from the bags. When approached by bridge staff, Mosquera claimed the leakage was oil, then fled.
Upon inspection, authorities found human remains inside. The grim discovery triggered a joint investigation between the Metropolitan Police and Avon and Somerset Police, leading to Mosquera’s arrest shortly after.
Detectives later revealed that Mosquera had searched online for deep freezers and ways to dispose of bodies, as well as making Google Translate queries about fatal head injuries, chilling evidence of premeditation.

During the trial, jurors were shown disturbing footage of Mosquera singing and dancing after stabbing Alfonso, and evidence that he attempted to steal £4,000 from the victims’ bank accounts immediately after their deaths.
Justice Bennathan described the murders as “thoroughly wicked and premeditated crimes,” adding that Mosquera “may never be safe to set free.” The judge imposed a minimum sentence of 40 years and 264 days, emphasizing the brutality and calculated nature of the killings.
Mosquera showed no visible remorse during sentencing, only smiling as he shook hands with his interpreter before being led away.
Sexual Exploitation, Violence, and Deception
Evidence revealed that Alfonso had long engaged in extreme sexual practices that he filmed and shared online. Over the years, his interactions with Mosquera escalated from consensual video exchanges to exploitation.
Mosquera claimed in court that Alfonso “raped him daily” and that the killings occurred after he “lost control.” However, prosecutors dismissed this claim as false, noting no evidence of coercion or mental illness and emphasizing that Mosquera’s actions, including freezer orders and disposal plans, proved his intent and composure.
Convicted of Child Exploitation Offences
Adding to the horror, Mosquera also pleaded guilty to three charges of possessing indecent images of children, totaling over 6,000 explicit files. Justice Bennathan called the content “appalling and depraved,” sentencing him to an additional 16 months, to run concurrently with his life term.
Investigators Still Searching for Answers
Despite the conviction, detectives remain puzzled as to why Mosquera chose Bristol as his dumping ground. Det. Insp. Neil Meade of Avon and Somerset Police remarked, “He could have committed almost the perfect murder, he didn’t need to dismember them or travel to Bristol.”
The case, described as “one of the most disturbing in modern British crime,” continues to raise questions about online exploitation, sexual violence, and transnational criminal behavior.
