The Brutal Murders of Albert Alfonso and Paul Longworth: They Were Murdered And Dismembered in Their Home



This article contains distressing details, including violence and descriptions of a sexual nature.


On the morning of July 8, 2024, a hired van pulled up outside a nondescript London flat. 

A man named Yostin Mosquera came out and loaded two heavy suitcases, which were carefully wrapped, into the van. 

The driver didn’t notice anything unusual as they headed for Bristol, which was about 116 miles away.

However, the police later found out that the suitcases contained the dismembered bodies of two men Mosquera had killed a few days earlier.

This chilling discovery brought an end to a complicated romantic relationship between Mosquera and his two victims — 62-year-old Albert Alfonso and 71-year-old Paul Longworth.

Let's get into the details. 

The Victims, Albert Alfonso and Paul Longworth 



A Private Couple with Hidden Lives

Albert Alfonso, a swimming instructor, and 71-year-old Paul Longworth, a retired handyman, were once married. 

However, after their marriage ended, they remained inseparable, living together in London and maintaining what friends described as a deep emotional bond.

Albert’s colleagues remembered him as a disciplined hotel manager who later became passionate about fitness. 

Paul was knowm as a friendly, regular guy who loved hanging out at pubs in Shepherd's Bush and was willing to buy a round for friends.

But behind what looked like a simple and normal life, Albert was living a completely different and disturbing one.

Since 2012, Albert had been in a chilling online relationship with Mosquera, a Colombian man who was 27 years younger than him. 

Over the years, Albert paid Mosquera thousands of pounds to create extreme sexual videos, which became increasingly disturbing as time went on. 

Albert later uploaded some of these videos to adult websites, earning over $15,000 over time.

For Mosquera, who received more than $5,000 from Albert, it was simply a money-for-content arrangement.

But Albert seemed to want some kind of romantic relationship, and that difference eventually led to a deadly outcome.

From Webcam to Real-World Violence 

Their online relationship eventually became physical in October 2023 when Mosquera visited London for the first time.

According to the BBC, it was Albert who invited Mosquera to London and paid for all the expenses.

During the visit, they spent time doing tourist activities like visiting Madame Tussauds and taking cruises on the River Thames.

They also had sexual activities together, but Mosquera later claimed they were non-consensual and that Albert raped him. 

However, overwhelming evidence later showed evidence that Mosquera willingly took part in the recorded sexual acts.

Mosquera eventually left London, and in March 2024, they met again for a second time — this time in Colombia.

While Albert and Paul were vacationing in Cartagena, Mosquera joined them there.

Friends said they had warned Paul about the risks of traveling there, but in photos, the three looked happy — smiling on boat rides and relaxing at the resort.

Albert and Paul left Mosquera after their vacation and returned to London. 

In June 2024, Mosquera traveled back to London to see Albert, and this visit marked the beginning of the end.

Criminal investigations later uncovered chilling evidence that Mosquera had planned to harm Albert and Paul before he even left for London.

This included disturbing internet searches he made before the trip, such as "how to poison someone undetected," "arsenic effects," and "chest freezer large enough for human body."

On July 8, Mosquera attacked Paul first, crushing his skull with a hammer before concealing the body. 

When Albert returned home, Mosquera had sex with him while recording the act. 

But during the encounter, Mosquera suddenly stabbed him to death — all while the camera was still recording.

Surveillance footage later showed Mosquera withdrawing cash from Albert's accounts and purchasing tools which he later used to dispose their body.

For the next three days after the murder, Mosquera stayed in the flat and took his time to dismember both Albert and Paul's bodies.

He stored their heads in a freezer he had recently bought and packed their limbs into suitcases.

He later hired a van, loaded the suitcases, and started heading to Bristol’s Clifton Suspension Bridge, where he planned to throw them over into the river. 

But his plan failed when the van driver saw blood, got suspicious, and called the police.

Mosquera fled the scene, leaving the suitcases behind, but he was arrested a few days later and charged with murder. 


Justice For The victims 

During his trial at Woolwich Crown Court, prosecutors described Mosquera as a calculated killer.

They said he was driven by money and anger  after he discovered that Albert had been selling their videos online.

Mosquera claimed he didn’t know Albert was making money from the videos, but authorities said he had signed an agreement allowing Albert to sell them.

The defense argued that Mosquera was abused by the victim.

However, this argument was weakened by overwhelming evidence which showed that he willingly took part and was paid for the arrangement.

In July 2025, Mosquera was found guilty of both murders, and he is set to be sentenced in October 2025.
