(AP Photo/Santa Monica Police Department) A disturbing clue from the Santa Monica gunman's past: In 2006, police found bomb-making materials in John Zawahri's home. They searched the house after Zawahri threatened students at his high school, according to a member of the Santa Monica-Malibu school board who lived next-door to Zawahri's father, Samir. The school district superintendent confirms that Zawahri was removed from his continuation high school that year due to a risk of violence, the Los Angeles Times reports. One of his teachers noticed "disturbing behaviors," including Zawahri talking about weapons and threatening students, which is when police were alerted. Around that time, they found the pipe bomb materials, and the school board was briefed. Earlier this week, one of Zawahri's teachers recalled that a student told him Zawahri had invited the student to his house, showed him a sword, and named specific students he wanted to hurt. He was taken to a psychiatric ward after that incident, but was not there long. Click for more on the Zawahri family's dark past. Read These Next Trumps ends trade talks with Canada.
