The deaths of Albert Alfonso and Paul Longworth at the hands of Yostin Mosquera have unveiled a disturbing world filled with explicit sexual content, dark web videos, and adult entertainment creation. However, the dynamics among the three men raise questions—how did they become acquainted, and what prompted Mosquera to take their lives?

Caution: The following article contains potentially distressing content, including graphic violence and sexual themes.

In a snapshot taken during a luxury speedboat excursion in Colombia, Albert Alfonso appears to be sharing a joyful moment with Yostin Mosquera and Paul Longworth, giving an impression of deep friendship.

However, beneath the facade lies a complicated web of human interactions intertwined with elements of extreme sexual interests, dominance, and financial dealings, coexisting with expressions of affection and care.

Just four months after that cheerful photo was taken, Mosquera brutally murdered both men in their London residence on July 8, 2024. He subsequently dismembered their remains and transported them over 116 miles (186 kilometers) in a suitcase. Utilizing a man with a van to reach Bristol, Mosquera planned to dispose of the bodies off the city’s suspension bridge.

Albert, aged 62, and Paul, 71, although once in a civil union, had separated but chose to maintain their close living arrangement. Authorities noted that the two men lacked extensive family networks and friend circles, effectively becoming each other’s sole support systems.

Albert worked as a swimming instructor and was preparing to become a lifeguard at the Mode Club Gym in Acton, west London. Originally from Bidart, France, he had honed his skills at a hotel school in Biarritz before managing hotels in the UK. He previously held the position of general manager at 375 Kensington High Street, a high-end residential estate in west London.

Colleagues who provided statements to Woolwich Crown Court described Albert as possessing a great sense of humor, leadership qualities, and strong motivation. He met Paul, a recently retired handyman, at his workplace, and their shared experiences with foster care helped solidify their bond. In February 2023, they formalized their partnership, though Paul’s friends reported that he was not open about his sexuality, referring to Albert merely as his brother.

Friends and neighbors painted Paul as a notably compassionate individual. Kevin Dore, 74, who had known Paul for over two decades, recalled him as “a kind, warm, and generous soul”—always polite and ready for a conversation over drinks. George Hutchison echoed this sentiment, calling him a good-natured man who never harmed anyone.

While Albert initially seemed private about his personal affairs, the ensuing trial exposed a side of his life characterized by the procurement and sharing of explicit content online—activities Paul had no involvement in, though he was aware and appeared accepting of it.

Mosquera, a Colombian national, also engaged in creating extreme adult content and posted numerous videos online under different aliases. At 35 years old, he lived in Medellín, coming from a large family that included five brothers and one sister who had passed away, and he is a father to two children.

Albert and Mosquera’s relationship began around 2012 through Skype, and by 2017, Albert was financially supporting Mosquera for increasingly explicit videos. Their first face-to-face meeting occurred in 2023 when Mosquera traveled to England.

It appears that Albert may have misjudged the nature of their relationship; while he sought a sexual connection, Mosquera had ulterior financial motives. Evidence presented at court indicated that Albert had disclosed significant personal details to a man with whom he had a fundamentally transactional relationship.

Between September 2, 2022, and July 12, 2024, Albert’s bank records show he received over £17,500 from a company associated with extreme pornography. Meanwhile, between May 2022 and February 2024, he made 72 payments totaling $7,735 (equivalent to about £5,800) to Mosquera, alongside additional transfers through MoneyGram.

For his part, Mosquera underreported awareness of Albert’s online sharing of their videos until mere days before the killings, even though he had signed a consent agreement in 2023 permitting Albert to post content featuring him.

During Mosquera’s visit to the UK in October 2023—funded by Albert—Mosquera stayed at his home, where he claimed to experience daily assaults by Albert, expressing no enjoyment in the extreme sexual acts he was paid to perform.

While engaged in activities as tourists, such as visiting Madame Tussauds and exploring the River Thames, Mosquera had been researching details regarding Albert and Paul’s financial situation and had searched for a chest freezer, an industrial blender, and lethal substances.

On July 8, 2024, the two men met violent ends—Paul was brutally bludgeoned with a hammer, and his body concealed beneath a divan bed as Mosquera awaited Albert’s return. In a recorded encounter, Mosquera fatally stabbed Albert and celebrated his actions.

Following the murders, Mosquera attempted to transfer £4,000 from Albert’s account to his own in Colombia, as well as making other withdrawals at local ATMs. Days later, he dismembered the bodies, stowing heads in a chest freezer and transporting body parts in suitcases to Bristol.

The shocking and violent nature of Albert and Paul’s deaths sent ripples of distress through their community. Kevin Dore expressed heartache over the brutal circumstances surrounding the murders.

Ultimately, Mosquera was found guilty of both murders following a trial at Woolwich Crown Court, with sentencing set to take place in October.
