A man murdered a couple, dismembered their bodies and then froze some of their remains before taking the rest in suitcases to the Clifton Suspension Bridge in Bristol, a court has heard.

Yostin Andres Mosquera filmed himself having sex with and stabbing Albert Alfonso, 62, having earlier killed Paul Longworth, 71, the prosecution told the Old Bailey.

Mr Mosquera, 35, denies the murder of both men at their flat in Shepherd's Bush, west London.

He admitted the manslaughter, by way of loss of self-control, of Mr Alfonso but the prosecution rejected this plea.

The prosecution alleges Mr Mosquera murdered both men on 8 July 2024, killing Mr Longworth first and then hiding his body in the storage section of Mr Longworth's bed.

Mr Longworth had been attacked with a hammer to the back of his head and Mr Alfonso had been repeatedly stabbed, the court heard.

The pair were in a long-term relationship and a year before their death they had entered into a civil partnership together, the prosecution told the jury.

'Extreme sex'

Prosecutor Deanna Heer KC said Mr Mosquera "could hardly deny" killing Mr Alfonso, telling them the attack took place while the defendant and Mr Alfonso were having sex and that both the sex and the killing were filmed.

Mr Mosquera was also recorded singing and dancing in the aftermath of the attack, the Old Bailey heard.

The court was also told that Mr Mosquera blamed Mr Alfonso for the death of Mr Longworth.

Mr Alfonso liked "extreme sex" which Mr Longworth knew about and accepted, but had "nothing to do with", the court heard.

Jurors were told Mr Mosquera visited the UK more than once and spent time with Mr Alfonso and Mr Longworth, engaging in sex acts with Mr Alfonso in exchange for payment, and that the couple also visited the defendant in his home country of Colombia.

Mr Alfonso paid the defendant and another man, known under a pseudonym as James Smith, to perform degrading sexual acts which were often filmed and posted online, jurors were told.

'PowerPoint record'

Ms Heer told the court that the trio "seemed to enjoy one another's company" and described how Mr Alfonso arranged a guest membership for Mr Mosquera at the gym where he worked and asked for him to be included in the staff five-a-side football WhatsApp group.

On Mr Mosquera's claims over the death of Mr Longworth, Ms Heer said Mr Alfonso had no reason to kill his "lifelong friend and partner".

"Their relationship was undoubtedly unconventional but whatever you may think about the way that Albert Alfonso conducted his sex life, the evidence also suggests that they accepted one another and that they cared for one another," she said.

The court heard that after the attacks, Mr Mosquera used the computer in Mr Alfonso's room to steal from him.

An examination of it showed Mr Mosquera had created a PowerPoint document of the couple's banking information, accessed a spreadsheet which contained their passwords for online banking, and had attempted to access Mr Alfonso's different accounts to transfer money - including trying to send £4,000 to his own account in Colombia, the court heard.

He made several cash withdrawals from Mr Alfonso's different bank accounts, obtaining at least £900 before the transactions started getting declined, the court was told.

Mr Mosquera is also said to have messaged Mr Alfonso's manager the morning after the killing from the victim's phone to say he was flying to Costa Rica for a family emergency and planned to stay for about eight weeks.

At about 23:30 BST on 10 July, a cyclist making his way across the Clifton Suspension Bridge spotted Mr Mosquera standing next to a large red suitcase, the prosecutor said.

The defendant told a cyclist he had car parts inside the suitcase and a large silver trunk, the court heard.

Ms Heer told the court the suitcases contained the decapitated and dismembered bodies of Mr Longworth and Mr Alfonso.

The luggage had an address label on it, which led detectives to the couple's home in Shepherd's Bush, where other body parts were found in a chest freezer.

Mr Mosquera, a Colombian national, wearing a white shirt and blue jeans, sat in the dock and listened to proceedings with the help of an interpreter.

The trial continues.
