SOMERSET, Wis. -- A teenager in western Wisconsin has built a device that could save lives in the event of an active shooter situation.
WCCO reports that Justin Rivard, a senior at Somerset High School, came up with the idea after noticing a potential flaw in the school's emergency response plan.
The 'Justinkase' lock starts with two steel plates cut to a specific shape. Handles are welded to them, and a rod and tube are welded on to connect the end place. Finally, a locking knob is added.
His principal, Shannon Donnelly, even pushed him to get a patent for the device.
During his summer off in 2017, he built enough devices for every classroom and conference room in the high school. The device retails for $95.
