I think many of us when sleuthing poi's in this case really noticed the "everyone is connected" thing and have felt that would play a role when this case is solved. Many of us focused on the drug connections, criminals, RSO's, etc... that's human nature to do, it's always the bad guy that can be picked out, right?
LE has flat out told us the answer will be a shock to the community.
IMO LE has said what they can to prepare for the heartache.
I believe BG's connections will also be shocking.
Imagine if his family members are LE, community leaders, coaches, etc...
Here's the thing. Statements by LE as presented above imply that LE knows who murdered the girls. Yet here we are 4 1/2 years after their murder, and there is no arrest. That is way too much time to let a murderer walk around free. Something is wrong. And what is going to change in the future? They are going to wait until they get that "one tip" that will allow them to arrest the murderer, who they already have identified?
If they know who did it, do a full-court press on them. Follow the guy 24/7. Give them no peace. Interview the neighbors, the co-workers, the family, again and again. Stress the outstanding reward. Search his past--their pasts. Search internet usage. Find something to arrest him for--guarantee a guy like this is a lawbreaker. Put him in jail and plant undercover inmates in his cell. Do what it takes to put this evil person away for the rest of their life. Do something beside wait for that one tip that will let them solve the case! My opinion only.
