The murder weapons have never been located.[1] The killer had taken several items which detectives found puzzling, including the keys to the victims' motorcycles, which themselves had been left behind. Gustafsson's shoes were partially hidden approximately 500 meters from the murder site. The police did not cordon off the site nor record the details of the scene (later seen as a major error) and almost immediately allowed a crowd of police officers and other people to trample around and disturb the evidence.
