When I started this episode, I honestly thought that it was pretty clear what happened. A family that didn't really understand their daughter missed the signs leading up to her tragic suicide. That said, there are a few items related to this case that don't quite fit. I'm not sure if it's enough to say for sure that this wasn't a suicide, but it is possible that she was murdered. The only annoying thing about this episode is: why did they make this one and not one of the many other compelling cases out there? This also would've been great if it was like the old episodes, packaged with other stories with less substance.
