By then, though, detectives already had no shortage of evidence to go on. Found in the wreckage of the fire was the Czech-made pistol used in the killings of the nine foreigners, and also one belonging to the murdered policewoman. And as if to remove any doubts, police also discovered a home-made DVD, in which a computer mock-up of the Pink Panther cartoon embarked on a "tour" of the different murder scenes. Chillingly, it included footage that only someone present at the killings could have shot.
