Don't worry, the undead aren't walking the earth, attacking people in Montana. The moaning, shambling figures you see are simply Montanans who are struggling through the winter.

Cindy Paavola, the University of Northern Michigan spokesperson, said that through the investigation so far, authorities believe they know where the source is coming from and that it is international. Right now the assumption is that they are cases in Montana and Northern Michigan are all connected, but it has not been confirmed.
According to Cynthia Thompson of ABC 10 in Northern Michigan, the party responsible for the attack in Montana — and what appears to be an identical hoax in northern Michigan — has been identified by law enforcement. It was determined that a “back-door” attack allowed the hacker to access the security of the EAS equipment, Thompson said.
It is unknown at this time if the suspect — or suspects, possibly — have been charged.
Great Falls police Sgt. Bryan Slavik said throughout the day he’s received calls from the BBC in London, newspapers in Australia and Canada, the New York Times, Washington Post and Chicago Tribune, as well as TV and radio stations around the world. The questions are all the same, and his response has been that Great Falls is taking it as the joke that it is, although if the perpetrators decided to make it more serious, then the hoax would not funny(sic).
Indeed. Though, truth be told, it is kinda funny. Hopefully though, this marks the death-knell for the zombie craze (The Walking Dead not included, because that show is fantastic). This business has gone on too long, dammit.
