OK, I missed that info, my bad. Hunted they were. Guy flipped out seems like. Either that or he was the killer next door nobody knew. And that is creepy, believe me, I lived in NYC during Son of Sam.
He ALSO went back, realized one of them wasn't dead after being shot...and shot him again to make sure he had no witnesses.
Have you read his confession to the police? I can link it if you'd like.
Just two months ago it was me out in the woods with my bow. If I had found someone in my stand it would have never occured to me to call the cops. I would have just asked him to move as I have done in the past. No muss no fuss. Why should there be? It isn't as if they still hang you for poaching the kings deer.
Now everything has changed but I know why those hunters did what they did. You worry about some nitwit with more hair then brains shooting you by accident but murder? That is stuff that happens in the city. Not out in the woods. not until now.
