London Murderer Jailed for Life After Dismembering Couple and Dumping Remains Near Clifton Bridge
London, UK – October 24, 2025 – In a landmark legal decision, a London murderer jailed for life will serve a minimum of 40 years after brutally dismembering a civil partnership couple and attempting to dispose of their remains near Clifton Bridge. Yostin Andres Mosquera, 35, has been handed a life sentence with a minimum term of 40 years and 264 days for the horrific crimes committed against Albert Alfonso, 62, and Paul Longworth, 71, in a case that has shocked the UK.
A Grisly Discovery and a Harrowing Investigation
The grim discovery that led to this London murderer jailed sentence unfolded on the evening of July 10, 2024. Members of the public spotted Mosquera acting suspiciously with two heavy suitcases near the Clifton Suspension Bridge. One suitcase was seen leaking a red substance, prompting serious concern. Mosquera fled the scene, but alerted police soon discovered the gruesome truth: the suitcases contained human body parts. This event triggered a complex investigation into the West London murders, described by detectives as one of the most harrowing they have ever encountered, which ultimately linked the remains back to a flat in Shepherd’s Bush, west London.
Brutal Murders in a West London Flat
The investigation into this shocking London murder case revealed that the murders took place on July 8, 2024, in the west London home shared by civil partners Albert Alfonso and Paul Longworth. Mosquera, who had been staying with the couple, unleashed a brutal attack. Paul Longworth was killed first, bludgeoned repeatedly with a hammer to the back of his head, an assault that shattered his skull. Albert Alfonso was subsequently stabbed at least 13 times to his torso, face, and neck. Disturbingly, Alfonso’s murder occurred during a filmed sexual encounter, with footage played in court showing Mosquera’s callous reaction. Mosquera had been involved in a relationship with Alfonso, which Longworth was aware of and accepted, a fact that adds another layer to the tragedy of this couple murdered UK incident.
The Plan for Disposal and Attempted Theft
Following the murders, Mosquera engaged in the gruesome act of decapitation and dismemberment. Parts of their remains were frozen, while the rest were packed into two suitcases. Mosquera then embarked on a 115-mile journey to Bristol, intending to dispose of the suitcases by throwing them from the Clifton Suspension Bridge. This act of disposal was part of a broader scheme that also included attempts to steal from the victims’ bank accounts. Minutes after killing Alfonso, Mosquera accessed his computer to find financial details and tried to transfer £4,000 to his account in Colombia. He also searched for information on how to inflict fatal injuries and about purchasing freezers, pointing towards a premeditated dismemberment crime.
Justice Served: Sentencing and Additional Convictions
Mosquera was apprehended by police on July 13, 2024, at Bristol Temple Meads railway station. He was convicted of both murders by a jury at Woolwich Crown Court in July 2025, having denied murder and claiming self-defence or loss of control. This conviction solidifies the London murderer jailed outcome. In addition to the murder convictions, Mosquera also pleaded guilty to three counts of possessing indecent images of children, for which he received a concurrent sentence of 16 months.
During the sentencing on October 24, 2025, Mr. Justice Bennathan described Mosquera as an “odd man” who committed “premeditated and thoroughly wicked crimes.” He emphasized that Mosquera might never be deemed safe for release, highlighting the severity of his actions and reinforcing the significance of this London murderer jailed verdict. He noted Mosquera’s Colombian nationality, stating he would be deported if ever released.
The case has deeply affected the Metropolitan Police and Avon and Somerset Police, who collaborated on the complex investigation into the West London murders and the Clifton Bridge discovery. Detective Chief Inspector Ollie Stride remarked on the harrowing nature of the murders and the graphic footage involved. The sentence aims to provide some measure of justice and closure for the families and friends of Albert Alfonso and Paul Longworth, who were described as a settled, affectionate couple whose lives were tragically cut short by Yostin Andres Mosquera‘s actions and the subsequent sentencing of this London murderer jailed.
