FARMINGTON, N.M. (AP) — A northwestern New Mexico high school student is facing charges after writing a threatening message about a school shooting. Police say a 16-year-old Piedra Vista High School student was arrested this week after staff found the handwritten message in a boys' bathroom. The student was detained following a review of security footage outside the bathroom. Farmington police spokeswoman Georgette Allen says officers found no evidence the suspect was planning a school shooting. The student is being charged with four counts of criminal damage to property and one count of "disrupting the educational process." The arrest came a month after a 21-year-old man secretly came on to the campus of Aztec High School in nearby Aztec, New Mexico, and fatally shot two students before shooting himself.
