Yostin Andres Mosquera, 35, was sentenced at Woolwich Crown Court to life with a minimum term of 42 years for the murder of partners Albert Alfonso, 62, and Paul Longworth, 71, before discarding their remains in suitcases near Bristol’s Clifton Suspension Bridge.
Disturbingly, the killer was seen asking Mr Alfonso "you likey?" after he stabbed him, before the victim "becomes limp". The footage then showed Mosquera "singing and dancing" while stepping towards a desktop computer in the room, as per The BBC.
Sentencing for indecent images
He has also received a 16-month sentence for possessing "horrifying" indecent images and videos of children. Three new charges were presented to him prior to the murder sentencing, and he pleaded guilty to three counts of possessing indecent photographs or pseudo-photographs of children.
Mr Justice Bennathan sentenced Mosquera to 16 months, telling 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 murders and discovery
Mosquera repeatedly stabbed Alberto Alfonso, 62, and slit his throat during a recorded sex session just hours after bludgeoning his partner Paul Longworth, 71, over the head with a hammer in 2024. Mosquera, who had been living with the pair at their flat in Scotts Road, Shepherd's Bush, west London, "decapitated and dismembered" them, froze portions of their bodies and took the remainder in suitcases to Clifton Suspension Bridge in Bristol, the jury was told.
He repeatedly knifed Mr Alfonso, who sustained wounds to his torso, face and neck, while Mr Longworth was bludgeoned with a hammer to the back of his head, shattering his skull, Woolwich Crown Court was told. Mr Alfonso was knifed to death during a recorded sex session, with video evidence presented in court capturing Mosquera singing and dancing following the brutal assault.
The horrific murders first came to light when the luggage was discovered on the famous bridge at 11.30pm on July 10 2024. One of the suitcases bore a label linking it to an address in Scotts Road, where officers subsequently found the heads in the freezer.
Defence and conviction
Mosquera's scheme was to throw the suitcases from the bridge to dispose of the bodies following the "calculated" and "premeditated" slayings, prosecutor Deanna Heer KC stated. Mosquera acknowledged killing Mr Alfonso but argued it constituted manslaughter due to loss of control. He denied murdering both victims and maintained that Mr Alfonso had killed Mr Longworth.
The jury took five hours and three minutes to unanimously convict Mosquera of the charges. He informed the jury that he feared for his own life and believed he was on the brink of being killed when he stabbed Mr Alfonso. The defendant alleged he thought Mr Alfonso would do to him what he claims he had already done to Mr Longworth, he felt "intimidated" and threats had been made against his family in Colombia.
Mosquera's behaviour following the stabbing of Mr Alfonso, which included singing and dancing, could have been an outburst as he had been overwhelmed by all that had transpired, his defence counsel proposed. The judge declared all the prison sentences for those offences will run concurrently.
