Rebecca Wang was just 7 years old the first time it happened.
She remembers vividly her teacher’s panicked face, and her urgent voice telling Rebecca and her classmates to keep quiet, hide behind their desks and stay calm.
They were barricaded in a Los Gatos classroom for four hours until police found the man who’d run across their campus with a gun. Wang didn’t understand what was going on, but when they finally walked outside, her entire family was waiting — and they looked terrified.

“It’s sad that we felt like we had to make this device. But as students, this isn’t something we can just choose to ignore,” said Swarnya Srivastava, a rising senior at Monta Vista High School in Cupertino, and member of the SIREN team.
In 2022, there were over 300 school shootings across the country, according to the K-12 School Shooting Database. This year, we’re on track for even more, with 178 school shootings recorded during the first six months alone.
