Similar incidents have been reported across the country in the past day.

On Wednesday, police officers shot and killed a man—believed to have been an employee—at the WTS Paradigm software company in Middleton, WI. Four people were injured, at least one seriously, after a “heavily armed” man entered the company’s offices, and opened fire around 10:30 a.m. The suspect—who has yet to be publicly identified—was struck by police gunfire and died later at a nearby hospital.
