A man who murdered two people and took their bodies in suitcases to Bristol's Clifton Suspension Bridge has been sentenced to life imprisonment with a minimum term of 42 years.

Yostin Andres Mosquera, from Colombia, killed Albert Alfonso and Paul Longworth in west London on 8 July last year, carrying out what the judge described as "premeditated and thoroughly wicked crimes".

The 35-year-old was caught when members of the public noticed blood leaking from the cases. He ran away but was caught a few days later.

Mosquera had been flown to London by Mr Alfonso and Mr Longworth, who were civil partners he had struck up a friendship with. Mosquera and Mr Alfonso also engaged in extreme sexual acts at the couple's Shepherd's Bush flat.

Mr Longworth, 71, was hit over the head with a hammer, shattering his skull, before his body was stuffed in a divan bed.

The same evening, during sex, Mosquera repeatedly stabbed Mr Alfonso, 62, in the neck, torso and face, asking him "Do you like it?" as he struggled and screamed.

The murder was caught on a bedroom camera, which also captured Mosquera singing and dancing as his victim lay dying.

Seconds later, he used a computer to try to steal from his victims' bank accounts.

He then decapitated their bodies and put the heads in a freezer that he had delivered the next day.

The other remains were put in suitcases, and Mosquera hired a van to take him to Bristol on 10 July, where prosecutors said he planned to throw the remains off the bridge.

When he arrived, people at a pub saw him struggling with the luggage, which he said contained car parts, and offered to drive him over the bridge.

'Is there a body in there?'

They struggled to lift the cases into the car, joking: "God, these are heavy, is there a body in there?", so ordered the killer a taxi instead.

He later told a cyclist, who spotted him on the bridge with a large red suitcase and a silver trunk, that they contained car parts.

Bridge staff noticed something appeared to be leaking from the red suitcase, which Mosquera told them was oil.

When they shone their torches on the suitcases, he fled.

The trial at Woolwich Crown Court was told that Mosquera - who had been selling sexual images of himself online for years - was motivated by money. He repeatedly tried to find out the price of the couple's flat and stole money from Mr Alfonso after murdering him.

The Colombian denied murdering both men, but admitted the manslaughter of Mr Alfonso by reason of loss of control.

'Premeditated and thoroughly wicked crimes'

Mosquera claimed Mr Alfonso killed Mr Longworth, telling the jury he believed he was about to be killed when he stabbed Mr Alfonso.

He was found guilty of the murders in July.

Mr Justice Bennathan told the defendant, who wore a wooden crucifix necklace and appeared to be smiling as he left at the end of the hearing, that Paul Longworth and Albert Alfonso "were a settled, affectionate couple".

He added: "It was their tragedy that you, Yostin Mosquera, came into their lives. I now have to sentence you for these premeditated and thoroughly wicked crimes."

The judge described Mr Alfonso as "a hardworking man who had shown [Mosquera] kindness and generosity", while Mr Longworth was a "harmless, amiable person who had done [the defendant] no wrong".

He said he was "sure" Mosquera hoped to sell the couple's flat after killing them, and added that the attacks were "undoubtedly murders committed for gain".

'Traumatic and harrowing'

Detective Chief Inspector Ollie Stride, who led the investigation, told reporters outside court that the "traumatic" case was "one of the most harrowing murders my team and I have ever investigated".

Officers had, he said, watched the murder of Albert Alfonso "numerous times" and the images "will stay with all of us for a very long time".

Mr Alfonso and Mr Longworth, who shared "a loving, caring relationship," were murdered "in the most brutal and callous of ways", he said.

He added: "The couple had opened their door to a man so evil he would take advantage of their lively spirits and generosity and murder them to satisfy his own gains."

Sentenced over indecent images

Before being sentenced for the double murder, he was jailed for 16 months on Friday for possessing "horrifying" indecent images and videos of children.

Three new charges were put to him prior to the sentencing and he pleaded guilty to three counts of possessing indecent photographs or pseudo-photographs of children.

Mr Bennathan said that unlawful child abuse content was found on Mosquera's laptop. As he jailed the defendant, he told him: "After you were arrested your laptop and other devices were seized.

"They were examined and in it were found at least 1,500 category A indecent photographs or pseudo-photographs, some of them moving images of children.

"They were very young children being subjected to a variety of sexual abuse really of horrifying detail and nature."

The judge said the jail term for those offences would run concurrently to the sentence for the murders of Mr Alfonso and Mr Longworth.
