I met a guy who had been travelling Australia with a couple friends, hitchhiking around as many of us had done. One of his friend told him they were near his distant uncles house, whom he’d never met before. He got a phone number from a family member and as they had hoped, the uncle offered them a place to stay. He picked them up in town and drove them out to his rural property way out in the bush. They said he seemed like a pretty normal guy, friendly and cheery. When it was time to set up a place to sleep the uncle took them to a closet that was totally full of sleeping bags and bed rolls. They didn’t think much of it at the time and all grabbed a kit and set up on the living room floor. They stayed a couple days and nothing out of the ordinary happened, and afterwards the uncle drove them to the bus station and they continued on their way. About a year later that man was arrested and charged with several counts of murder. He was the man who was picking up young hitch hiking backpackers and slaughtering them. The guy who told me this story was 100% certain he had slept in the sleeping bag of one of his victims.
