Just watching
I'm 54 minutes in.
Don't spoil the ending. But, my money is leaning towards Sylvie, the 'best friend'. The reason is because Sylvie has been the only other person in their house that's close enough to Julie that she could manipulate evidence. The diary, for instance. The knife. Usually friends will tell their bestie about a diary before they tell their parents.
But, don't tell me. I am watching this on my DVR so I can FF the ads.
I'll see in the end.
Side note: Ed Flynn gets on my nerves.
Crappiest lawyer on TV ever.
