Police: San Ramon teen planned school shooting 'deadlier than Columbine,' recruited friend

San Ramon police confirmed on Thursday that a California High School freshman arrested last month had been planning a school shooting to take place on April 20, 2021 - exactly 22 years after the deadly Columbine shooting.

"I want to commend our student for doing the right thing and reporting the information to an adult…The safety of our students, staff and parent community is our highest priority, and we take all threats seriously."

San Ramon police told KTVU there will be extra security at a graduation ceremony on Friday out of an abundance of caution.
