Two teachers—one in Massachusetts, the other in Nevada—were killed at their schools last week, allegedly by students.
In Danvers, Mass., a 14-year-old high school student was accused of killing a well-liked math teacher, whose body was found in the woods behind Danvers High School.
Colleen Ritzer, 24, was reported missing late on Oct. 22. Investigators found blood in a second-floor school bathroom and located her body early the next morning. The cause of death was not released.
The suspect, Philip Chism, was arraigned as an adult that same day on a murder charge.
In Sparks, Nev., a middle school student opened fire in the schoolyard, killing a teacher who was trying to protect other children, according to police.
Michael Landsberry, a 45-year-old ex-Marine who taught math and coached basketball and soccer, was killed during the altercation that erupted shortly before classes began Oct. 21.
Two other students were shot and are recovering from their wounds.
The suspected gunman, a 7th grader at Sparks Middle School who turned the semi-automatic handgun on himself, is also dead, authorities said.
Investigators have confirmed the 12-year-old shooter acted alone, but have released no information about a motive.
