The case
Albert Alfonso and Paul Longworth had been together about twenty years and lived in a flat in Shepherd’s Bush, west London. Alfonso, sixty-two, was a swimming instructor; Longworth, seventy-one, was a handyman who had recently retired. Yostin Mosquera, a thirty-four-year-old adult film performer from Medellín, Colombia, had been their guest before and came back in June 2024.
On July 8, 2024, around midday, Mosquera killed Longworth with a hammer while Alfonso was out. That night he cut Alfonso’s throat during a filmed session, using a knife he had hidden. Three weeks earlier he had been pricing chest freezers, and on July 4 he set about having one delivered. On the morning of the killings he searched for where a blow to the head would be fatal. He dismembered both men, left their heads in the freezer and packed the rest into two suitcases.
He hired a van to Bristol, planning to drop the cases into the Avon Gorge from the Clifton Suspension Bridge. Passersby saw blood seeping from them and challenged him, and he ran. Police arrested him at Bristol Temple Meads station on July 13. A first trial collapsed in May 2025; a jury at Woolwich Crown Court convicted him of both murders on July 21, 2025, and on October 24 Mr Justice Bennathan jailed him for life with a minimum of forty-two years.

Where it happened
Why this case
“It is the planning that the sentencing judge fixed on, and that is what I would ask readers to sit with. Mosquera was pricing a chest freezer three weeks ahead and looked up where to strike a fatal blow on the day itself. Albert Alfonso and Paul Longworth had built twenty quiet years, and he ended both in a day.”
