Before a lynch mob forms, there is a degree of uncertainty whether the person at the keyboard was actually the guy behind the username (Kyle Guthrie). For example, he could have left his computer without logging out of the spotternetwork and somebody else sat down at the computer and started to have fun posting as that user. (Chances are that would be a friend or acquaintance, given the time of day, so he should still be questioned, IMHO).
Does the spotternetwork.org site have a cookie that is placed upon log-in? If so, you might consider giving it a shorter expiration time so that this becomes less likely. I think most people would not mind being required to log-in again more often, if it helped prevent this sort of oversight (if that is what it was). It seems unlikely to me that someone with his experience would do this, particularly under his own username. I think there is plenty of reason to consider him innocent until proven guilty (besides that being the way our justice system should work).
However, there is quite a bit of publicly available information on Kyle Guthrie, stormchaser starting with:

which associate him with a "
Tarrant County Storm Chase Interceptor Team".

His YouTube profile page:

This video associates him with a third name:

I guess I find it interesting (under the circumstances) that the username picture seems to be of Kyle Guthrie (based upon Flickr profile info) but the YouTube video is TAGS are
Michaela Vallejo
He gives his home town as "Dallas/Ft. Worth", "Bedford", or Burkburnett, or "Wichita Falls area". Since these cover different dates, moving around is indicated.
