There are laws to deal with the guy if these was a scheme to profit. If he was deluded there's no reason to take actions, he's no worse than the idiots who ran around because of his rumors. In fact his action was better. By forwarding his news he's inviting conversation and investigation, by running off to the school the terrified parents are actually potentially causing a problem.
