A chilling double murder in London has unearthed a disturbing story of exploitation, adult content, and ultimately, cold-blooded violence. Yostin Mosquera, a 35-year-old Colombian national, has been found guilty of murdering Albert Alfonso and Paul Longworth in their Acton flat on July 8, 2024, before dismembering their bodies and transporting them in suitcases to Bristol.
Albert, 62, and Paul, 71, were once civil partners, and though no longer romantically involved, they remained housemates and close companions. Described by police as having “no huge family or friend circles,” they were said to be “each other’s everything.”

Albert, originally from Bidart, France, worked as a swimming instructor and was training to be a lifeguard. He had a background in luxury hotel management and previously served as general manager at a high-end development on Kensington High Street. Paul, a retired handyman, was known in Shepherd’s Bush for his warmth and generosity. Friends described him as “a very nice man, never did anybody any harm.”
But beneath the surface of their quiet lives, a far darker story was unfolding.
The trial at Woolwich Crown Court revealed Albert’s secret life as a creator and participant in extreme adult content. He had been in contact with Mosquera since 2012 through Skype, paying him for sexual videos starting in 2017. Over time, the content became more graphic, with Albert eventually uploading videos of Mosquera, under pseudonyms, across several adult sites.
Between 2022 and 2024, Albert paid Mosquera nearly £6,000 and received over £17,500 from a company associated with extreme pornography. Despite signing a consent form in 2023, Mosquera later claimed he was unaware his images had been published. He told the court he was repeatedly raped by Albert and did not willingly participate in the sex acts, though evidence showed he had profited from the content and maintained online profiles.
In October 2023, Mosquera travelled to the UK at Albert’s expense, staying in his home. During his stay, he visited tourist attractions and joined Albert’s gym and five-a-side football WhatsApp group. In March 2024, Albert took Paul to Colombia, where they again met Mosquera, despite friends warning Paul against the trip. By June, Mosquera was back in the UK, and Albert had even enrolled him in an English language course.
But beneath the hospitality, Mosquera was plotting.

In the days before the murders, he searched online for chest freezers, industrial blenders, arsenic and poisons. He also looked into Albert and Paul’s finances.
On July 8, Mosquera struck first, attacking Paul with a hammer and hiding his body inside a divan bed. He then waited for Albert, whom he stabbed to death during a filmed sexual encounter. In a disturbing detail, he reportedly sang and danced after the killing. He attempted to transfer £4,000 to his Colombian account and made withdrawals from Albert’s bank accounts.
Days later, Mosquera dismembered both bodies, placing their heads in a freezer and packing body parts into suitcases. He hired a man with a van and travelled over 180km to Bristol, planning to dispose of the remains from a suspension bridge.
The shocking brutality of the crime devastated the local community. Kevin Dore, a close friend of Paul, said the murders had broken his heart. “He was always polite. Always kind. Just a nice, warm person,” he said.
Mosquera was convicted of both murders after a detailed and graphic trial. He is due to be sentenced in October.
The case has left many grappling with the reality that behind smiling photographs and quiet lives, hidden worlds of abuse, manipulation and desperation can spiral fatally out of control.
