Gunn High School was shut down Thursday afternoon after a student reported a "threatening" Facebook post to Palo Alto police, Superintendent Max McGee said Friday.
The Gunn student called police after becoming concerned about a photo and post on Facebook made by a student who attends Alta Vista High School in Mountain View, a continuation high school that both Palo Alto Unified and Mountain View-Los Altos school district students attend, McGee said. McGee did not know if the Alta Vista student had attended Gunn or not.
Palo Alto police contacted Gunn Principal Denise Herrmann and Katya Villalobos, who runs the high school's summer school program. The district "chose to be cautious" and cancelled all athletic practices and summer camps at Gunn through the evening, McGee wrote an email sent to district parents Thursday night. A parent posted the email on Palo Alto Online's Town Square.
The post did not include a specific threat to any individuals or schools in the Palo Alto Unified School District, but because a Gunn student made the call to police, the school was shut down, McGee said.
Police approved the reopening of campus in the evening, McGee said. Summer school classes will continue as normal today, July 17, though there will be police presence on campus. Students enrolled in the last session of the summer currently have class daily from 8 a.m. to 1:30 p.m.
Palo Alto Police Office Kelly Burger said Friday that police remained on campus for an investigation Thursday afternoon, but ultimately the case was referred to another jurisdiction and agency for follow-up. McGee said police reached the Alta Vista student's family and turned the case over to Mountain View police.
McGee applauded the student who called the police, especially in light of a shooting the same day in which a gunman opened fire at a Naval facility in Tennessee, killing four Marines.
"I talk so much about the importance of being vigilant," McGee said. "This is exactly what we're trying to teach students."
