A man gave a Nazi salute, shouted out "White Power," and called a stranger "Jew-boy" just moments before knocking him down outside a St. Louis diner and stomping on his head with work boots, jurors were told Wednesday. The man on trial, Kevin A. Johnson, "spewed out these racial slurs" in a burst of hatred toward the victim, Michael Schnelle, Assistant Circuit Attorney Robert Craddick said in opening statements of Johnson's murder trial.
