A man who killed two men and dumped their remains in suitcases by Clifton Suspension Bridge has been jailed for life.

Yostin Mosquera, 35, denied murdering Paul Longworth and Albert Alfonso but a jury at Woolwich Crown Court found him guilty in July and he was sentenced to life in prison on Friday.

The jury heard Colombian national Mosquera “decapitated and dismembered” the pair while staying at their flat in Shepherd’s Bush, London, before putting some of their remains in two suitcases which he dragged to the suspension bridge in Bristol.

Sentencing Mosquera to a minimum of 40 years and 264 days, Judge Justice Bennathan said: “I stress that is a minimum, you may never be safe to set free”.

He added that the murders, which took place on 11 July 2024, were “thoroughly wicked crimes”.

Mosquera had a blank expression while he was being sentenced.

After the judge finished speaking, Mosquera smiled as he shook his interpreter’s hand and then he smiled at the court before he was led down.

Earlier Mosquera had pleaded guilty to three charges of possessing indecent images of children, for which he was sentenced to 16 months in jail.

He will serve this sentence concurrently with his double-murder sentence.

Mr Justice Bennathan said Mosquera was “actively involved in a network sharing indecent images of children”.

The judge added: “Your laptop contained thousands of appalling pictures and films of the gross sexual abuse of very young children.”

Mosquera admitted killing Mr Alfonso but claimed it was manslaughter by reason of loss of control.

He blamed Mr Longworth’s death on Mr Alfonso.

During the trial, jurors were told Mr Alfonso, 62, enjoyed “extreme sex” which he frequently paid for, participated in and shared videos online.

Mosquera was living in Medellin, in Colombia, when he started speaking with Mr Alfonso over Skype in 2012 and by 2017 Mr Alfonso began paying Mosquera for sexual videos which reportedly became more extreme over time.

The pair met in 2023 for the first time when Mr Alfonso paid for Mosquera to travel to England and stay at his flat with his close friend Mr Longworth, 71.

Mr Alfonso and Mr Longworth became civil partners but later split up in 2023.

The court heard Mosquera and Mr Alfonso engaged in extreme sex sessions during the visit. Mr Longworth did not involve himself with the activity.

When Mosquera was invited to London for a second time in 2024, he stabbed Mr Alfonso to death during a filmed sex session.

Footage shown in court showed Mosquera singing and dancing in the aftermath of the attack.

He had killed Mr Longworth with a hammer earlier the same day, shattering his skull with 13 blows to the head, and hid the body in a divan bed in the apartment.

During the trial, Mosquera claimed he was “raped every day” by Mr Alfonso which made him feel “humiliated, sad and trapped”, but never angry.

Prosecutor Deanna Heer KC told the court Mosquera’s “detailed” defence statement produced for the trial made no “mention of Albert Alfonso raping you”.

According to a mental health report compiled on Mosquera, he was not suffering any mental health problems when he carried out the murders.

Similarly, prosecutor Deanna Heer KC said Mosquera was not a victim of coercive control.

Mr Justice Bennathan said the relationship between Mr Alfonso and Mosquera was “transactional”.

“You were well looked after [and given] a gym membership, a trip to Brighton, you began to research the value of the flat.”

He added: “That seemed to you a vast amount of money – it was naïve of you to think you could sell it [the flat] after they were dead.”

The leading detectives on the case said they remained puzzled as to why Mosquera took the dismembered bodies to Bristol.

“[It’s] one of the things I’ve never been able to get to the bottom of,” Det Ch Insp Ollie Stride, from the Metropolitan Police, said.

Senior investigating officer for Avon and Somerset Police’s major crime team Det Insp Neil Meade also asked why Mosquera “exposed himself” to being caught, when he could have booked a plane ticket back to Colombia.

“He could have committed almost the perfect murder,” he said.

“He didn’t need to dismember them, he didn’t need to take them to Bristol.”
