According to the news conference with the Sheriff just one shooter. About twenty wounded and 4 dead including the shooter. Some of the wounded were shot in cars on the highway. 4 dead inside the plant. A Hesston law officer was on the scene almost immediately. He faced the shooter and took him down. Hesston is a small town, population less than 4,000, so this officer was alone. I know I make jokes about Barney and Goober when talking about our rural cops but really, they are heroes, every one. --s6
