Man Kills, Dismembers Two Lovers
A Colombian national, Yostin Andres Mosquera, 35, has been jailed for life imprisonment with a minimum term of 40 years for the brutal murders and dismemberment of two men whose remains were found in London and Bristol.
Mosquera, of Scotts Road, Shepherd’s Bush, was convicted at Woolwich Crown Court after a chilling investigation by the Metropolitan Police uncovered how he murdered and butchered 71-year-old Paul Longworth and 62-year-old Albert Alfonso, who were in a long-term civil partnership, before attempting to dispose of their body parts in suitcases.
The couple were killed in their Shepherd’s Bush flat on 8 July 2024, in what detectives described as one of the most disturbing and cold-blooded murders ever investigated.
Two days later, Mosquera was seen in Bristol with two heavy suitcases leaking a red substance, claiming it was “oil”. Suspicious residents alerted police after witnessing him behaving oddly near the Clifton Suspension Bridge. When officers opened the cases, they discovered human remains, triggering a full-scale murder probe.
A search of the victims’ flat in Shepherd’s Bush uncovered the decapitated heads of both men stored in a chest freezer, along with the murder weapons nearby.
Detectives later pieced together a mountain of evidence showing that Mosquera planned the killings for financial gain.
He had searched online for “how long it takes a body to decompose,” “where to strike a fatal blow,” and even the value of the victims’ property.
He also attempted to hack into their bank accounts after the murders, unsuccessfully trying to transfer £4,000 to his own account in Colombia.
According to investigators, Mosquera had been living with the couple for about a month before the murders and was in a sexual relationship with Albert, which Paul tolerated.

On the day of the killings, Mosquera bludgeoned Paul to death with a hammer, hiding his body beneath a bed before ambushing Albert later that evening. Disturbingly, the second murder was captured on video, as cameras in Albert’s bedroom recorded Mosquera stabbing and slashing his throat during a supposed intimate encounter.
Detective Chief Inspector Ollie Stride described the murders as “harrowing beyond words.” “Paul and Albert welcomed Mosquera into their home, only for him to betray their kindness in the most horrific way imaginable,” Stride said.
“This sentence ensures a dangerous and remorseless killer will never again walk free.”
Detective Inspector Neil Meade from Avon and Somerset Police called the crimes “truly barbaric,” adding that Mosquera’s attempt to dispose of the remains in Bristol showed a chilling level of calculation.
“He showed no remorse whatsoever,” Meade said. “While we may never understand his motives completely, I’m grateful justice has finally been served.”
Mosquera was arrested in Bristol on 13 July 2024, just days after the murders. Despite admitting to killing Albert, he claimed it was manslaughter due to “loss of control” and tried to blame Albert for Paul’s death, a defence the jury flatly rejected.
The court heard that the case left investigators and community members deeply traumatised, prompting close collaboration between police and LGBT+ support groups to handle the sensitive aftermath.
With Mosquera now behind bars for life, detectives said the 40-year minimum sentence reflects the monstrous brutality of the crime and brings a measure of closure to the victims’ loved ones.
“Nothing can bring Paul and Albert back,” Stride said, “but justice has finally caught up with the evil man who took their lives.”
