GREENWOOD, Ind. (AP) — Authorities say the person who shot five people at a suburban Indianapolis shopping mall, killing three of them, before a shopper shot and killed him was a 20-year-old local man. Greenwood Police Chief James Ison said at a news conference Monday that Jonathan Sapirman, of Greenwood, began firing after leaving a bathroom at the Greenwood Park Mall shortly before it closed Sunday evening. He says Sapirman continued shooting people until a 22-year-old man who was legally armed shot and killed him. Authorities say the 22-year-old was shopping at the mall with his girlfriend and that he acted heroically.
