My GUESS based on my experience with NOCO, is that IF this is a random shooter, it is possible IMO that there are other potential incidents to which we may not be privy to. Moo.
Furthermore, IF a random shooter, is he also a pyro?
Based on the report of a suspicious fire, which of course may or may not be linked, can we find any other suspicious fire incidents in the nearby area/timeframe?
There should be a fire dept incident response log out there, not that all incidents are contained in such logs (depending upon if the fire dept did indeed end up responding, etc).
Ps, carbuff, it was not me who suggested the texting idea, thanks for thinking of me though.
