David Paulides was interviewed in the video below and at about the 52:00 minute mark he talks about the young men found in water. A few autopsys were done by the parents of the boys that went further than what the police had done. What they found was the boys had high levels of a chemical called GHB in their blood. It's a date rape drug and when it's used with alcohol it can cause some weird things to happen. It's an interesting interview on people that have gone missing in Canada.
