Gun sellers in Missouri, including a Wal-Mart, "recklessly failed" to stop a felon from illegally buying the guns used by a white supremacist in deadly 2014 shootings outside Jewish sites, according to a lawsuit filed this week. Frazier Glenn Cross, 74, a former senior member of the Ku Klux Klan white supremacist organization, was sentenced to death in November for his attacks in Overland Park, Kansas, two years ago this week. Cross was found guilty of killing Reat Underwood, 14, and his grandfather, William Corporon, 69, outside the Jewish Community Center of Greater Kansas City, and Terri LaManno, 53, outside a Jewish retirement home.
