Porn actor suitcase killer said 4 chilling words to fetish slave as he cut his throat in 'extreme' sex', court told

A killer Colombian ‘porn performer’ said four words as he slashed the throat of his fetish slave during sex, hours after hammering the man’s civil partner to death and hiding him under a bed, a court has heard. Yostin Andres Mosquera, 35, is on trial at the Old Bailey accused of murdering Albert Alfonso, 62, originally from France, and Irishman Paul Longworth, 71, at their West London flat on July 8 last year.

Video footage of Mr Alfonso’s final moments, which was caught by cameras set up to film his sex session with Mosquera at the flat in Shepherd’s Bush, was played to jurors on Wednesday (April 30). It is alleged Mosquera asked Mr Alfonso ‘Do you like it?’ as he repeatedly stabbed him in the neck, face, and torso, moments after urinating on him while wearing a strap-on penis.

Mosquera - whose guilty plea to the manslaughter of Mr Alfonso was not accepted by the prosecution - is then alleged to have dismembered the bodies of the couple, storing their heads in a chest freezer, before taking the other remains in a pair of suitcases to the Clifton Suspension Bridge in Bristol.

There, Mosquera pretended he was a man called Juan dropping off mechanical parts for a client, and assured a pair of football fans that the red liquid leaking from one of the suitcases was just motor oil, the court was told.

But eventually, a cyclist and staff working on the bridge confronted Mosquera and asked to look inside the suitcase. Mosquera refused and ran away from the scene, but was arrested at Bristol Temple Meads station a few days later, wearing a single shoe and a t-shirt with Mr Alfonso’s blood on it.

Men hung out as friends

On Wednesday (April 30), jurors heard that Mosquera blames Mr Alfonso for Mr Longworth’s death, and denies murdering Mr Alfonso due to loss of control.

Prosecutor Deanne Heer KC told jurors how Mr Alfonso, a swimming instructor at a gym in Acton, was into ‘extreme’ sex, while his partner Mr Longworth, a handyman, was dyslexic and relied on Mr Alfonso for help in their ‘loving’ relationship.

Mr Alfonso sought other men, who he had sex with and posted films on specialist websites, including Mosquera, who went 'iamblackmaster' and 'mrd**k20cm' in his online pornographic content, and a man known as James Smith (a pseudonym used to protect his identity for the trial), who Mr Alfonso had known for around 18 years.

Mr Alfonso used both men to engage in acts of sexual domination, which included acts to degrade Mr Alfonso like urinating, defecating and vomiting on him.

As well as their sex sessions, the men hung out together as friends, and Mr Alfonso and Mr Longworth visited Mosquera in his native Colombia.

But in the weeks before the men were killed, Ms Heer said Mosquera made a number of internet searches that showed he ‘had an interest in killing’, including for chest freezers and industrial blenders, house prices for the couple’s flat, 'Serial killers of London', and 'Jack the Ripper film'.

Defendant danced over victim's dead body

On the morning of Mr Longworth’s death on July 8, Mosquera searched for YouTube videos about how fatal a head knock is, and looked at an image of a chest freezer that prosecutors say is similar to the one the remains were later found in, the court heard.

Ms Heer said it was likely Mr Longworth was killed when the curtains were closed between 12.30pm and 1pm, and that post-mortem analysis had shown the injuries to the back and top of his skull were consistent with ‘forceful use of a hammer’.

The prosecutor also said DNA evidence showed it was likely his body was hidden in his own bed. In the evening, while Mr Alfonso was at the gym, Mosquera made searches about how long it takes for a body to decompose, the court heard.

Drawing on evidence from the video recording, Ms Heer said Mr Alfonso was likely killed at around 10.15pm that same night while he was having sex with Mosquera.

Ms Heer told jurors the footage showed Mr Alfonso on all floors with Mosquera penetrating him with a strap-on penis and urinating on him from behind, with the men apparently engaged in a master/slave fetish roleplay.

Mosquera then applied tape to Mr Alfonso’s bottom, cut it away with scissors, then reached for a knife on a table, and finally applied more tape to Mr Alfonso’s behind, the jury heard.

Then, as the sex continued, Mosquera reached around and pulled Mr Alfonso’s head back and ‘ quite deliberately, quite precisely’ inserted it into his neck, said Ms Heer. After that, a struggle ensued, and Mosquera came out on top.

“He begins to struggle but the defendant - younger, fitter and obviously stronger - manages to overpower him and repeatedly stabs him, at one point asking, ‘Do you like it?’ before he eventually pushes Alfonso onto the bed and cuts his throat,” said Ms Heer.

The footage then showed Mosquera dancing naked with Mr Alfonso’s body twitching on the floor next to him. Immediately, Mosquera set about attempting to drain money from the couple’s bank accounts by accessing spreadsheets with banking passwords on Mr Alfonso’s desktop computer, it is alleged.

Later, when Mr Alfonso’s boss asked why he was not at work, Mosquera posed as Mr Alfonso and claimed he had a family emergency in Costa Rica, the court heard. After dismembering the bodies and putting some of the remains in a newly delivered chest freezer, he agreed to pay a ‘man with a van’ to drive him to Bristol.

'His head, hands and feet had been removed'

Unable to lift the heavy suitcase over the side of the bridge, it was here bridge staff and a passing cyclist confronted Mosquera about the red liquid leaking from the case, prompting him to flee the scene and leave behind the remains of Mr Alfonso and Mr Longworth, it is alleged.

When police arrived and looked inside the suitcases, they found the remains of Mr Longworth in the silver suitcase, 'with attached arms and two detached legs… His head, hands and feet had been removed’. Mr Alfonso’s remains were in the red suitcase ‘with attached arms and hands and two detached legs with attached feet… his head had been removed’.

The remaining body parts and heads were found in the chest freezer at the victims’ London flat. A pathologist who looked at all the remains found some of the cuts were consistent with the use of a knife, while others had been done with a saw or power tool.

At the flat, forensics found Mr Alfonso’s blood splattered around his bedroom, while there were towels drenched with Mr Longworth’s blood in his own room, and his hair on the edge of the bed. Police also recovered strap-on prosthetic penises, sex toys, a bloodstained knife, and the couple’s electronic devices in the communal bins.

Ms Heer said Mosquera 'remained at large' until he was arrested sitting on a bench outside Bristol Temple Meads station at 2.15am on July 13. The defendant had with him a rucksack with a wallet, passport, and phone, wearing only one shoe and a red t-shirt stained with Albert Alfonso's blood.

Under questioning the next day, he said he injured his foot running away the day before his arrest when his shoe came off, and that he cut his elbow in Colombia when he was carrying bricks. To the other questions, he made no comment.

'A deliberate and calculated act of killing'

“The defendant is guilty of nothing less than the murder of both Paul Longworth and Albert Alfonso,” Ms Heer told jurors, adding: “Albert Alfonso simply had no reason to kill his lifelong friend and partner, Paul Longworth. Their relationship was unconventional, but whatever you may think about the way Albert Alfonso conducted his sex life, the evidence suggests that they accepted one another and cared for one another.”

Ms Heer said the evidence pointed towards Mosquera as Mr Longworth’s killer, particularly his internet searches for how to kill someone by striking their head, and the sameness of the chest freezer he was researching and the one the remains were found in.

Ms Heer said that the footage of Mosquera killing Mr Alfonso showed he was ‘in complete control’ of his actions, which she described as ‘strategic and premeditated’.

“He armed himself with the knife and waited for the opportunity to use it to cut Mr Alfonso’s throat in a deliberate and calculated act of killing. And having done so, as Albert Alfonso lay dying at his feet, the defendant immediately went to his computer and set about stealing, or trying to steal, from him,” she said.

The trial under Mr Justice Bennathan continues.
