Not everything is a conspiracy - the investigators and Medical Examiner who worked on this case are some of the best in the world. My guess would be they checked for any foreign fingerprints preset on the duct tape and items on their bodies and found only that of the sisters, in such a way as to show they had bound one another. Also, they probably conducted numerous interviews with everyone associated with them... Suicides are not always as we think they are: When I worked as a Director of Investigations at a 425-bed long-term care psychiatric facility (most resident had schizophrenia, some had severe personality disorders), one resident who committed suicide was the last person in the world I would have thought would do this. He left the facility very early in the morning, walking out the front door (which was always locked and had to be buzzed open by the receptionist) as a few people came in through the open door as the receptionist was distracted and looking the other way. He killed himself by jumping head-first into a very rocky area of Lake Michigan. His head exploded upon contact with the rocks. He did not leave a note. His room was clean and organized, as if he were intending to come back. His Case Manager had no idea he was suicidal. Other staff had no idea he was suicidal. His friends had no idea he was suicidal. As it turned out he had said to his mother only 1-2 days before that he was, "going to jump into the lake to end everything". She never told any of us at the hospital because she thought he was just messing around... A while back Jim Ellison, the vocalist of the band Material Issue (they were a very popular Indie band in Chicago back in the late 1980's and early 1990's) had come over to mine and my roommate's apartment the day before he left this world (both of us had worked as professional musicians way back when, and knew him well - Material Issue actually played a number of shows with the band I was in at the time): He was carrying 3 cans of very, very warm beer from the plastic rings just out in the open... When he came in I offered him some really good ice cold beer that I had, but he refused, choosing instead to drink one of his own - I thought this was kind of odd. He sat down on the couch, but hardly spoke. He had a barely noticeable soft, sweet smile on his face, but was really emotionally distant, like he was somewhere else. He then left after a couple of hours, and my roommate and I just kind of looked at each other and were like, "what the hell was that"? We were very concerned for him because he seemed to be in an odd place psychologically, but we had absolutely no idea at all how much he was actually hurting from the recent break-up with his girlfriend, and what he had planned to do about it: The very next day he went into his garage, closed it up, turned on his scooter, and died from carbon monoxide poisoning. None of us ever, ever, ever thought that would happen... The simple fact is that human behavior is completely unpredictable - we're much too complicated a species; so, in these cases, all you have to go on are the facts that you can uncover!
