Considering this crime was committed after "normal working hours", and considering the area that the CO covers from that office, its lucky he was even in town and was able to get away from whatever personal life he was enjoying in order to do his job, and do it well.
I'm guessing he went out into the woods, in the dark, alone, after individuals that he knew were armed. The dude is a stud. I have met him a few years ago and he was an impressive individual.
Kudos to the CO for his role in this. And kudos to the citizen that recognized something and reported it.
