(NPR) -- When a man pulled a shotgun out from under a long coat and started shooting into a church congregation near Fort Worth, Texas, last winter, Jack Wilson didn't hesitate. Within seconds, the volunteer security guard unholstered his weapon and returned fire.
With one shot, Wilson killed the 43-year-old gunman and then kicked the shotgun away. Keith Thomas Kinnunen had already shot two congregants, who died. But there were more than 250 people in the West Freeway Church of Christ that day, on Dec. 29, and many credit Wilson for saving many more lives.
The shootings were recorded on video from a livestream camera that was on during the church service.
