Greenwood Park Mall, Indiana -

On July 17, a 22-year-old man opened fire at the food court of the Greenwood Park Mall in Greenwood, Indiana. The shooter used what appeared to be a long-gun rifle to shoot five people, one male and four females. Three of the victims died, while the two others, one of whom was a 12-year-old girl, were brought to hospital and are in stable conditions. The perpetrator was shot and killed by a civilian who was lawfully carrying his own gun and happened to be in the food court when the shooting broke out. Local law enforcement are praising the local man who may have saved many lives with his quick action. 

The motivations of the gunman are still under investigation as the town mourns those who were lost. "This tragedy hits at the core of our community," Greenwood Mayor Mark Meyers said in a Facebook post. "Please offer your prayers to the victims and our first responders."
