Don't know what yet? That he has thrown it all away?
Honestly, after reading everything and trying to be as objective as I possibly can, I see no good way out of this. Even if he doesn't get charged, or even if he doesn't get arrested, and even if he escapes scrutiny by the NFL personal conduct policy, how do you think Kraft and/or Belichick would see his involvement in the loss of a human life, in light of his abrasive personality, his history of being difficult to manage?
Even the Myra-less Kraft has already has thrown down the gauntlet, barring Herandez from Patriot property. That is a clear contravention of the "innocent until proven guilty" stance that the organization usually takes with its players.
