WASHINGTON, D.C.: A US judge Tuesday sentenced to death a gunman who killed three people in attacks last year at Jewish sites in the state of Kansas, local media reported Tuesday. Frazier Glenn Cross, 74, is a white supremacist who was convicted of the murders in a jury trial in September. “Your attempt to terrorize this community has failed,” Johnson County Kansas Judge Thomas Kelly Ryan said in ruling that the gunman be executed by lethal injection. Cross, handling his own defense in court, said Tuesday he should be released because he was justified in trying to kill Jews. “I wanted to kill Jews, not Christians,” Cross said. Of those killed in his attack, none were Jewish.
