Meanwhile, in New Mexico, schools on the Jicarilla Apache Reservation were placed on lockdown Wednesday after a caller phoned in a threat of a mass shooting. The nearby Navajo Technical University also locked down for several hours. Elsewhere, in Dalton, Georgia, police arrested 53-year-old social studies teacher Jesse Randall Davidson after he barricaded himself alone inside a classroom and fired shots from a pistol as a principal tried to enter. This is Dalton Police spokesperson Bruce Frazier.

Bruce Frazier: “When the principal put a key in the door to try to unlock the classroom, Mr. Davidson apparently fired a shot from a handgun through an exterior window of the classroom. It did not appear that it was aimed at anybody. It obviously broke out the window. And at that point the school went into lockdown.”
