It does seem like he was on a mission to kill. By most accounts it all happened very quickly, especially since other walkers heard nothing but they weren't all that far away.@PaulaDC I feel your frustration. He'll be identified and we'll all have closure from the horror of this craven act.
@Aydrianna523, I'm down with your thoughts on his brashness. He was on a "mission" and understood himself visible, yet took the chance. This has always seemed like a carefully premeditated seek-and-destroy mission to me, one with a heavy fantasy element to it. I look forward to hearing about the reasons for his brazenness in documentaries for the duration of this offender's long prison sentence.
It makes sense when I picture this crime as a youthful first-try kind of situation. The adjective lucky has been used here by all of us. Doesn't this feel like a kid's luck? A sick, cowardly, deviant man-child who now hides in plain sight.
