On December 5, 2007 19-year-old Robert Hawkins killed eight people and injured four in a shooting at an Omaha, NE mall.

His stepmother Candace Sims and father Ron Hawkins did an intense interview for Investigation Discovery’s first episode of Evil Lives Here, titled “Something About Robbie,” which first aired in 2016. They reveal that Robbie’s behavior growing up was disturbing, and he even tried to poison his stepmother.
