The New York Times reports that four high school students in the small California town of Tuolumne, about 120 miles east of San Francisco, have been arrested, but not yet charged, for planning an attack on their school, Summerville High School. According to the Times, three of the four were overheard discussing this plot, and a fourth conspirator was later identified. Their goal, according to Toulumne sheriff James Mele, was "to shoot and kill as many people as possible at the campus"; they had not however been able yet to obtain the weapons they wanted to carry out the attack. From NBC News' version of the story: "Detectives located evidence verifying a plot to shoot staff and students at Summerville High School," Mele said. "The suspects' plan was very detailed in nature and included names of would-be victims, locations and the methods in which the plan was to be carried out."
