The Norwegian man arrested for the attacks that left 77 people dead last month returned to the scene of the mass slaughter Saturday accompanied by police. Wearing a bulletproof vest and a leash, Anders Breivik guided investigators around Utoya Island for eight hours, simulating the killing of his 69 victims. Breivik has admitted to plotting and carrying out the attack, as well as the bombing of a building in Oslo that killed another eight people.
