Grim photos show the house of horrors where a Colombian porn actor murdered an older couple he was staying with before chopping up their bodies and dumping them on Clifton Suspension Bridge.

Civil partners Albert Alfonso, 62, and Paul Longworth, 71, welcomed 35-year-old Yostin Mosquera into their home in Scotts Road, Shepherd's Bush, west London.

Tragically, their flat would be transformed into a sinister murder scene as Mosquera hatched a twisted plot to kill both men and desperately cover his tracks on July 8 last year.

First, he bludgeoned Mr Longworth to death with a hammer, inflicting blow after blow on the same day he had searched ''where on the head is a knock fatal?' and 'hammer killer'.

Chilling photos released by the Met Police show the hammer he used at the scene, as well as the bloodied divan bed where Mosquera hid Mr Longworth's body so that Mr Alfonso - who was at work - would be none the wiser when he returned home.
