SOMERSET, Wisc. (WHDH) — A high school student in Wisconsin invented a door-lock device that could save lives during a school shooting.
Justin Rivard, a senior in high school, said he came up with the idea after noticing the doors at his school could be unlocked, even after a table was pushed against the door. His invention makes it nearly impossible to open the door.
“What kind of insurance are you going to get for a student’s life? This is the insurance right here,” said Rivard.
The device costs $95.
