I call FBI, so they can swoop in and get a win to counter the bad press.
If I were investigating, I'd run separate teams, each concentrating on the background of one target. Then, you MIGHT see where lines cross.
I'd bet that there was, or will be, ONE real target, and the rest of them is smoke and mirrors so that the entire system is tail chasing.
Motives are for TV. Who cares if Mommy didn't luv him enough?
