Police say a Texas man fatally shot three people in a Target parking lot, including a child and her grandfather. The suspect, 32-year-old Ethan Nieneker, allegedly acted unprovoked and chose his victims randomly. This happened on Monday during back-to-school shopping. After the shooting, Nieneker reportedly stole two cars before being arrested in Austin. Authorities say he has a history of mental health issues and previous arrests for domestic violence and assault. He is being held on capital murder charges. Police have not offered a motive for the shooting.
