The FBI is on the case but they don't have the file. Interesting. When I'm working on a project, you can bet I have the file. It sounds to me like the FBI has offered help but these people haven't taken them up on it. As we learned in the Sadek case, the FBI needs to be asked in. So.. I'm hoping they were able to get all of the file put together to give to the FBI by now since precious time is ticking away.
Furthermore.. I don't really expect all of the answers to these questions but we've gotten no new information since Sept 26, 2014. According to the police, they have no suspects, no motives and no POI. According to court records, they dropped the ball on the Snapchat info because they were pursuing other leads of which they've garnered no suspects, motives or POI's.
I went back and read the past threads on the case and you were very adamant this case would be solved immediately, Rocco. I guess you were wrong. Sometimes blindly trusting LE isn't the best course of action.
