Murder accused says victim threatened his family

A man accused of murdering and dismembering a couple claims his family was threatened by one of them.

Yostin Mosquera, 35, denies murdering Paul Longworth and Albert Alfonso at their flat in London, where he was staying.

The Colombian national told Woolwich Crown Court earlier that Mr Alfonso, 62, would "instruct" him to perform extreme sexual acts against his will, which left him feeling "empty".

Mr Mosquera said he "felt very sad and wanted to leave" the couple's home - but did not do so because Mr Alfonso told him he had friends in Colombia who would kill his family.

Mr Mosquera previously admitted the manslaughter of Mr Alfonso by way of loss of self-control.

He is accused of murdering him by stabbing him to death during a recorded sex session at a flat in Shepherds Bush on 8 July 2024.

He is also accused of killing Mr Longworth with a hammer earlier on the same day and of then hiding his body in a divan bed.

The court was previously told Mr Mosquera dismembered the bodies and took them to Clifton Suspension Bridge in Bristol in an effort to dispose of the remains.

Mr Mosquera told the jury Mr Alfonso was responsible for killing his partner.

As the defence case began earlier, Mr Mosquera said he met Mr Alfonso online in 2012.

He told the jury Mr Alfonso began paying him to make and send videos of himself performing sexual acts.

He said the acts he was asked to carry out became more extreme as time went on.

The court was told Mr Alfonso visited Mr Mosquera alone in Colombia in 2022 and was paid £59 ($80) to carry out sexual acts on Mr Alfonso in person.

The defendant said he then visited the couple in London in October 2023 and continued the sexual activity with Mr Alfonso.

He told the jury this was done against his will, but he carried out the acts because Mr Alfonso said he would help him pay for an English course.

The jury was told he was not paid, but Mr Alfonso gifted him an air fryer to give to his mother.

The couple visited Mr Mosquera in Colombia in 2024 and the three of them stayed in an apartment.

Mr Longworth had his own room and Mr Mosquera slept in a double bed with Mr Alfonso, where the paid sexual acts continued, the court heard.

Mr Longworth had no involvement in them, jurors were told.

"[Mr Alfonso] would instruct me to do things," Mr Mosquera said.

"He also told me to use my imagination, but he was the one telling me what to do in the sessions," he added.

The defendant said he "never" enjoyed the experience, but continued to carry out the acts for money.

The court was told Mr Alfonso paid for Mr Mosquera to fly to London later that year, where he remained up until the death of the civil partners.

Mr Mosquera said Mr Alfonso treated him "100% different" after he arrived in England.

The defendant said he called him stupid and an idiot "every day, all the time" and used racist language towards him.

While Mr Mosquera said he had previously been asked by Mr Alfonso to call him a slave during sex, he told the jury the names he was called in return were not part of any agreed role play.

The extreme sexual acts continued, the defendant said, which left him feeling "empty".

"I felt very sad and I just wanted to leave," he added.

He said he was made to sleep on Mr Alfonso's bedroom floor and had no control over where he went or who he saw, with his keys taken away whenever he left the flat.

Ms Mosquera said he had no issues with Mr Longworth, but he was often angry with the defendant "for no reason".

Speaking about the night of the men's deaths, the defendant said he heard the couple pushing each other in the bathroom.

He said he believed Mr Alfonso killed Mr Longworth.

He told the jury Mr Alfonso later told him he had "always had problems with Paul" and warned something would happen to his family in Colombia if he told anybody what had happened.

Mr Mosquera said he saw a hammer with a red substance, which he believed to be blood, in the kitchen.

Later in the day, the defendant said Mr Alfonso told him they needed to make a video of sexual activity, as they needed do so four times a day.

He said he then heard Mr Alfonso speaking in Spanish to someone while using a computer, saying he would not "leave any traces".

This led Mr Mosquera to feel like his head was "going to blow up like a balloon" as his mind started to race, he said.

Jurors were told he was thinking about how he had been treated, the threats to his family and about what he thought had happened to Mr Longworth.

The fear Mr Alfonso would kill him led to the defendant stabbing him during the sexual activity which came next, he said.

"I attacked him before he could attack me," he told the court.

The trial continues.
