Yostin Andres Mosquera has been found guilty of murdering civil partners Albert Alfonso, 62, and Paul Longworth, 71, on 8 July last year before putting their remains in suitcases and dumping them near the Clifton Suspension Bridge.
The couple were 'decapitated and dismembered' by Mosquera, who had been staying with them at their flat in Shepherd's Bush. He reportedly froze some of their remains before disposing of the rest in suitcases.
A jury today (21 July) found him guilty of the murders, with a court hearing that he repeatedly stabbed Alfonso in his torso, neck, and face while Longworth was struck on the back of the head with a hammer.
Jurors were shown footage of Mosquera 'dancing and singing' after the killings, and he was handed a unanimous guilty verdict.

The court heard that before carrying out the murders, Mosquera's search history showed he had been looking for a freezer, which he likely used to store some of his victims' remains.
Jurors heard that while he was the only person in the flat, Mosquera made several searches for items including a deep freezer, a chest freezer, a large indoor freezer, and an outdoor freezer.
Further computer searches that jurors were told about included 'serial killers of London' and 'Jack the Ripper film'. Many of the searches were made in Spanish which is Mosquera's first language.
In days before the killing, a computer at the flat was also used to search for the phrase 'hammer killer' and the question 'where on the head is a knock fatal?'.
Mosquera, who admitted manslaughter to Alfonso but denied killing Longworth, claimed to the court that Alfonso must have made those searches.
Prosecutors also said that Mosquera, a Colombian national, went onto the computer after the killings and tried to access money from his victims.
He was accused of duplicating Alfonso's bank login details and attempted to transfer £4,000 to his own account, and also made numerous cash withdrawals of around £900 before transactions were declined.
On 10 July, 2024, two days after the killings, Mosquera went to Clifton Suspension Bridge with two suitcases containing some of the remains of his victims. Prosecutors said he'd planned to throw the suitcases off the bridge to dispose of the bodies.
He was on the bridge when staff noticed that something appeared to be leaking from one of the suitcases. The convicted murderer initially claimed it was oil and said he was going to get his other case before running past it and attempting to escape.
His sentencing is due to take place on 24 October, but the judge said 'the only one I can pass on you is one of life imprisonment' as he ordered a psychiatric report on Mosquera.
The judge also acknowledged the 'serious demands on jurors' that the case had involved.
