When a small team of police and firefighters arrived, they encountered an odd scene: the bodies rested next to each other, partly covered by grass. Each one wore a formal suit, a lead eye mask, and a waterproof coat. There were no signs of trauma or any evidence of a struggle. Next to the corpses, police found an empty water bottle and a packet containing two wet towels. A small notebook was also identified, on which were written cryptic instructions.
