Who were Paul Longworth and Albert Alfonso?
The Bodies on the BridgeWhether you know the case as ‘The Suitcase Murders’ or ‘The Bodies on the Bridge,’ the Paul Longworth and Albert Alfonso killings were something the police and the rest of the country would never forget. In July 2024, the two men’s bodies were found decapitated in suitcases at the Clifton Suspension Bridge in Bristol.
But who was the man with the suitcases, and why did he commit such a heinous crime? His name was Yostin Andres Mosquera.
The shocking case is examined in detail in Crime+Investigation’s exclusive new documentary on the case, The Bodies on the Bridge. Ahead of the first episode airing on Monday 7th September, this article covers how the two men came to know their killer, and the events that led to their deaths.
A life together
Paul Longworth and Albert Alfonso had built a life together in West London.
71-year-old Paul was originally from Ireland, while 62-year-old Albert was a French native. The pair had been together for more than a decade and entered a civil partnership in February 2023.
Their relationship was not entirely conventional. Albert had sexual relationships with other men, something Paul knew about and accepted. It was through this part of Albert's life that the couple eventually came to know the man who would murder them.
How Albert Alfonso met his killer
Albert first met Mosquera through online webcam sites.
Mosquera was a Colombian national who worked as a pornographic performer. The pair developed a sexual relationship, with Mosquera being paid by Albert. The relationship was consensual and, according to the sentencing judge, entirely legal.
Mosquera visited Britain and spent time with Albert and Paul. He was part of their world. In October 2022, the couple invited him to stay with them in London. They also travelled to Colombia in March 2024 and visited Mosquera there.
By June that year, Mosquera was back in Britain. He was staying at the couple's home in Shepherd's Bush when everything changed.
But what caused Mosquera to murder Albert and his husband? And do so in such an extreme way?
The visit that turned deadly
After nearly a decade of friendship, things appeared to have turned sour. Mosquera's actions before the murders suggest a degree of premeditation. Before coming to the UK, Mosquera searched online for the value of the couple's Shepherd's Bush flat and in the days leading up to the murders, he was looking online for chest freezers and industrial blenders.
According to reports, he also searched the term: ‘where on the head is a knock fatal?’
On 8th July 2024, Paul was at home while Albert was out working. According to evidence presented at trial, Mosquera attacked Paul with a hammer. He struck him repeatedly on the back of the head, causing fatal injuries, before hiding his body beneath a bed. Later that evening, Albert returned home.
Mosquera killed him during a filmed sexual encounter. Albert was repeatedly stabbed and suffered 22 stab wounds. The attack was recorded on cameras that Albert had installed in the bedroom.
From Shepherd’s Bush to Bristol
But how did the couple’s bodies end up in Bristol? After killing and dismembering Paul, he hid his body in a divan bed. He then placed some of their remains in a chest freezer at the victim’s home.
Other parts were packed into suitcases and placed in a van that Mosquera had hired with a driver to take the bags from London to Clifton Suspension Bridge in Bristol, where he planned to dispose of them.
Locals even offered to help Mosquera lift his suitcases over the bridge when they saw he was struggling with their sheer weight. However, one member of the public noticed Mosquera behaving suspiciously.
Others became concerned when they noticed something leaking from one of the suitcases, with one reporting in a chilling call to police that ‘we’re convinced it’s blood’.
After being challenged, Mosquera fled from the area and was filmed by a member of the public who gave chase on a bicycle. In an attempt to deflect suspicion and escape, Mosquera was heard to shout ‘go away, my boss is really bad’ in Spanish to the onlooker.
Meanwhile, back on the grid, the grim discovery of what was inside the cases triggered a major police investigation.
The case and conclusion
The remains found in Bristol were traced back to the couple's home address in Shepherd's Bush.
Investigators quickly identified Albert and Paul as the victims. Mosquera became the focus of the investigation and was arrested at Bristol Temple Meads railway station on 13th July.
During the trial at Woolwich Crown Court, the footage of Albert’s murder was played on repeat to the jury. Albert had installed cameras in the room during the day of the murders.
The prosecution argued that Mosquera was financially motivated. He often tried to find out the value of the couple’s property and stole money from Albert after his death.
‘The video that we found of the murder is really shocking. Within seconds of the murder, he appears to dance, sings a short song, and immediately after that, whilst Mr Alfonso is still lying on the floor, he's straight on the computer and starts searching for... and logging into bank accounts.’ DCI Stride told news outlets.
The prosecution’s evidence was compelling, and the jury found Mosquera guilty in July 2025. He was sentenced to a minimum of 40 years behind bars by Judge Justice Bennathan in October 2025, who added, ‘I stress this is a minimum, you may never be safe to be set free.’
