At least four people are dead and as many as 20 injured after shootings at multiple locations north of Wichita, Kansas.Authorities said at least three victims were shot before a gunman walked into Excel Industries in Hesston, Kansas. Officers were called to the scene at the lawn care equipment manufacturer around 5 p.m. According to KWCH, about 1,000 employees work at the business.”He was a black male and had an AK and he just started spraying people. … Someone said this guy got fired, came back upset and just started shooting people,” Marty Pierce, an Excel employee, told KAKE.Law enforcement told reporters the gunman was in fact an employee at Excel Industries and was shot and killed by authorities. Officials said they’re investigating if the shootings at two other locations may be connected. Hesston is located about 40 miles from Wichita. Many of the victims were transported to area hospitals.”This is just a horrible incident that’s happened here to Harvey County, Hesston, Newton. It’s so spread out.
