Rick Odell Smith, 43, of Morgan County, Illinois, broke into a home and shot six people on April 24, 2013, including three children. All but one child died. Smith was later killed in a shoot-out with police. Police say the people killed were related to Rita Luark, with whom Smith had a child, and he believed they were interfering with his custody case.
Note how Smith was described at the end of the article: He was unemployed, had a criminal record including reckless homicide, passing bad checks and a drug-related charge. In other words, a sociopath.
