A former butcher has been found guilty of murdering a woman he met in his local pub before dismembering her body in a killing motivated by lust.
Christopher May invited fragile 47-year-old Tracey Woodford back to his flat in Pontypridd before strangling her and then having sex with her corpse before going on a three-hour online porn binge.
Cardiff Crown Court heard that two detectives carrying out routine inquiries into her disappearance were stunned after pulling back a shower curtain in May's home and discovering something resembling a scene from a horror film.
Ms Woodford's torso was found stuffed in a rucksack in May's cupboard - while her head was stashed 150 yards (138m) inside an underground tunnel.
The jury's verdict, which came less than an hour of deliberations, was met with cries of "Yes" from the public gallery.
