From the get-go, I didn't believe this was a murder-suicide. Having now read through all the comments, I gotta say, you all make some very interesting points that support both murder-suicide, and also double-homicide. I find I keep flip-flopping.
But in the end, I think I'm still leaning towards double-homicide. The facts just don't add up for me. I believe that it's true, TPS likely know so much more than we do, but they were just too quick to jump to conclusion. As they are skilled investigators, they still often get it wrong. Anyone from Toronto knows this.
I'd like to know more about what "ligature neck compression" really means. As it stands now, I'm inclined to believe that the "hanging" by the pool wasn't what killed them. It feels like some creepy, personal display. No forced entry is suspicious, but they could have likely opened the door to someone they knew. And I gotta say, after reading the articles regarding the cousins, specifically the Toronto Life one, they sound like angry, hateful people who feel very, very wronged. Especially that Kerry.
With that being said, having met so many different people throughout my life, and having followed more cases than I can count, I'm well aware that we never know what goes on behind close doors. Nothing would surprise me with this case at the moment, it's just too crazy, and there's so many possibilities.
