A hoax. That’s what Pocatello police are calling a Facebook posting that sent area schools into lock down this morning. Kim Ellis, with the Pocatello police department  say officers were able to identify  the suspect behind a Facebook "Event" post, which indicated a school shooting would occur Monday afternoon. The posting kept district 25 schools under lock down for most of the morning.  Police took the suspect into custody on a separate charge, and said the Facebook posting was a hoax. They were  also able to determine that no real threat existed.
