Legally armed driver shoots, kills gunman to stop fatal shooting spree in Indiana

A legally armed man shot and killed a gunman in Brownsburg, Ind., this week after a fatal unprovoked shooting, saving a second victim's life in the process.

The 22-year-old suspect, Joshua Christopher Hayes, allegedly attacked two men as they were working in the Brownsburg Cemetery Tuesday afternoon, Indianapolis-based WISH-TV reported.

Without provocation, Hayes allegedly chased 36-year-old worker Seth Robertson out into an intersection, where he shot and killed him, according to the station.
