A federal grand jury has filed 19 new charges, including hate crimes, against Robert Bowers, the accused gunman in last year’s mass shooting at Pittsburgh’s Tree of Life synagogue. On October 27, 11 Jewish worshipers were shot and killed in what has been described as the deadliest anti-Semitic attack in U.S. history. The indictment against Bowers cited his online attacks on the Jewish charity HIAS, including posts from the day of the shooting.
