That may be, but let's not forget it's not really up to Feldman to "have" anything. And, IMO, if the DA doesn't have a lot more than we are currently aware of, Feldman won't be needing much.
In any case, it's up to the prosecutor to provide the evidence to prove DW did it. We won't know for a few days what that might be, but we're getting mighty close.
As for me, I intend to keep an open mind as to what is presented and if the evidence is there, I will be the first to say hang him.
And therein lies the rub. Most of us would walk with you if there is more evidence than we have seen. If the parents were honest, that would certainly help things. Like I've said, I don't see it now, but prove he was in the room or at Dehesa with her, and we'll talk. And none of this we don't have evidence so connect the dots stuff.
