My guess is he will be found dead of exposure. I suppose anything is possible but that is the most likely ending.
I’m thinking he offed himself in a snowbank, not to be discovered until spring thaw. He has accepted the fact that he will not end this ‘mission’ alive, he has brought publicity upon LAPD’s corrupt practices, hurt the guy he most wanted (Father Quan), and instilled terror in the police. If terrorizing them was his goal, they are guaranteed to be on edge, for weeks, if my humble hypothesis is true. Just my 2 cents, of course. Thanks.
