The porn star who filmed extreme sex on the dark web and his 5,000 mile trek to murder

The brutal murder of Albert Alfonso and Paul Longworth has exposed a world of horror porn, extreme sex and dark web videos that resulted in Colombian killer Yostin Andres Mosquera travelling over 5,000 miles to carry out a deadly plot that he believed would be "the perfect murder". Four months before their death, in a case of extreme grooming, the three men enjoyed a luxury resort holiday in Colombia where people they met were unaware of the complex relationship they enjoyed, based on extreme sex, domination and financial transactions, all existing alongside a loving and caring partnership.

The unusual set-up ended when Mosquera mercilessly killed both men in their London flat on 8 July 2024, before dismembering their bodies, and travelling more than 116 miles with them in a suitcase. He hired a man with a van to drive him to Bristol, who dropped him off close to the city's suspension bridge, where Mosquera planned to throw them off.

Albert, 62, and Paul, 71, had previously been in a civil marriage and while they had split up, had remained close and continued to live together.

Police described the men as without "huge family, friend circles", instead being "each other's everything, their rocks and their world".

Albert was a swimming instructor and was training to be a lifeguard at Mode Club Gym in Acton, west London. He had grown up in Bidart, France, and trained at a hotel school in Biarritz before moving to the UK to manage hotels.

He was previously a general manager at 375 Kensington High Street - a luxury residential estate in west London with apartments and penthouses.

In statements read to Woolwich Crown Court, former colleagues of Albert described him as "funny, authoritative and motivated".

It was at this building that Albert met Paul, a handyman who had recently retired. They bonded over the fact they were both fostered and in February 2023 they entered a civil partnership, although Paul's friends claim he "wasn't open about his sexuality" and referred to Albert as his brother.

Paul was widely described by friends and neighbours as "extremely kind".

Kevin Dore, 74, from Shepherd's Bush, used to drink with Paul and knew him for more than 20 years, told the BBC: "He's a nice, warm, generous person. Always polite. Always buy you a drink, sit down and have a chat."

George Hutchison, who also used to drink with Paul, said: "He was just one of the boys. He was a very nice man, never did anybody any harm."

Although Albert was said to have been private about his personal life, the trial revealed a world of extreme sex which he frequently paid for, participated in and shared videos of online.

It was a side of his life that Paul had nothing to do with, although he knew about it and seemed to accept it.

Mosquera, a Colombian national, was also posting scores of videos of himself online performing extreme sex acts under various pseudonyms.

Aged 35, he lived in the Colombian town of Medellin, and had five brothers and one sister, who died a few years ago. He also has two children.

Albert and Mosquera started speaking over Skype from about 2012. By 2017, Albert started paying Mosquera for sexual videos, which reportedly became more extreme over time.

They finally met in person in 2023 when Mosquera travelled to England for the first time. But it seems Albert misjudged their sexual relationship.

While it seemed Albert was in it for the sex, Mosquera was in it for the money.

The court heard Albert had laid his whole life open to a man with whom his relationship was, in reality, transactional.

Albert's bank statements show he received more than £17,500 between 2 September 2022 and 12 July 2024 from a company that operates an extreme pornography website.

Between May 2022 and February 2024, Albert sent Mosquera a total of $7,735 across 72 payments - the equivalent of about £5,800.

And between January 2024 and 19 June 2024 Albert transferred £928 via MoneyGram, which provides international money transfer services.

In return, Mosquera posted porn across four websites, including more than 100 videos and images, online using pseudonyms.

Customers had asked for sex shows and between 30 June 2022 and 12 June 2024 he earned $2,682.90.

Mosquera claimed at trial he did not know Albert was sharing videos of him online until a few days before he murdered him - despite agreeing that he signed a consent form in 2023 allowing Albert to upload images of him online and for him to keep financial profits.

When Mosquera travelled to the UK in October 2023 he stayed in Albert's London home and the travel had been paid for by Albert.

Mosquera told the court he was raped "every day" by Albert and that he did not take any enjoyment from the extreme sex acts, which he was paid to perform.

During his stay, Mosquera visited Madame Tussauds, took a trip on an open top bus and went on a boat trip on the River Thames.

Then in March 2024, Albert took Paul to Colombia where they stayed in the city of Cartagena - and Albert paid for Mosquera to come and meet them.

In May that year Mosquera made another extreme video for Albert and within weeks he was back in the UK, staying with the pair - again at Albert's expense.

This time Albert arranged a guest membership for Mosquera at his gym, set him up to join his work's five-a-side football team Whatsapp group, and enrolled him on a four-week English language course.

The three men also travelled to Brighton for a day trip, visiting the pier and where Mosquera was filmed on a zip-wire.

However, in the days before Mosquera landed at Heathrow Airport and during his stay, he was accessing information about Albert and Paul's finances, searched for a chest freezer and industrial liquidiser as well as looking up deadly poisons and arsenic.

Paul was repeatedly hit with a hammer, shattering his skull. His body was then hidden in the bottom of a divan bed, while Mosquera waited for Albert to come home.

During a recorded sex session, Mosquera stabbed Albert to death, after which he sang and danced around the room.

He then accessed Albert's computer in an attempt to send £4,000 to his bank account in Colombia, as well as making other financial withdrawals.

When this failed, he went to a nearby cashpoint and withdrew hundreds of pounds from Albert's accounts.

Mosquera dismembered their bodies days later - placing their heads in the chest freezer and transporting other body parts in suitcases to Bristol.
