Ethan Nieneker went on a deadly rampage Monday afternoon in Austin, Texas, killing a Target employee, a 66-year-old man and his 4-year-old granddaughter.

Adam Chow, 65, and his 4-year-old granddaughter were killed alongside a Target employee in the triple homicide.

A Target employee collecting carts and a man and his granddaughter were gunned down in an unprovoked attack in Austin on Monday, police say.
