A superseding indictment issued Thursday alleges that Harpham left a backpack bomb along the parade route "because of actual or perceived race, color, and national origin of any person," in violation of the Hate Crimes Prevention Act.

Harpham, who is charged with three other counts, including attempting to use a weapon of mass destruction, faces life in prison.
