In NYC that would most likely be 10 years with the opportunity for parole in 5. Meanwhile the young lady will remain dead, and liberal or not all of her hopes and dreams were stripped away by this piece of human garbage.
In Texas or Ga he would end up with the needle. Florida he'd ride old sparky, but NY will coddle him and turn him back on the streets in a few years (if they even bother to find him at all, after all it wasn't a cop he killed, just an ordinary citizen - not like she's part of the precious government)
unfortunately, no "sparky" in Fla (IIRC). Believe it was retired after that guy's head caught fire.
