The prosecution said it followed from the lack of Gustafsson's blood on the shoes, that his injuries had occurred at a different time to the attack on the murdered victims, and that the only explanation of this was that Gustafsson had committed the murders, then faked the theft of items by hiding them, further injured himself and then went back to the tent where (now barefoot) he pretended to be unconscious. The prosecution attempted to bolster their case by alleging an identification by two birdwatchers of Gustafsson as the tall blond man at the scene on the crime, an assertion that he had been overheard making an incriminating remark, and also that a decade after the event he had boasted to a woman about his guilt.[8]
