A man charged with killing 11 people in a Pittsburgh synagogue should face the death penalty if convicted, federal prosecutors said in a court filing Monday. The U.S. attorney’s office in Pittsburgh filed a notice of intent to seek the death penalty against 46-year-old Robert Bowers in last year’s attack. The government filing said justification for a death sentence included allegations of substantial planning and premeditation, the vulnerability and number of victims, and a motivation of religious hostility.
