This makes it the last 4 events that I recall ending up being nothing but hysteria over nothing or with just the lone gunmen dead due to suicide.
This would be the worst of the 4 though as 3 were injured and hopefully all make a speedy and full recovery.
Event one: New Jersey mall gun-owner suicide
Event two: Yale lockdown for non-existant gunman
Event three: American University lockdown -- "gunman" ended up being off-duty police officer
Event four: Colorado HS 3 injured, one suicide
