Robert Bowers, 50, faces the death penalty for the 2018 attack on a Pittsburgh synagogue. Bowers burst into the Tree of Life synagogue in Pittsburgh, armed with three pistols and a semi-automatic assault rifle.
Shouting "all Jews must die," he opened fire and killed 11 people, including a 97-year-old worshipper. The trial, which is expected to last until July, is taking place against the backdrop of a surge in racist and anti-Semitic acts in the United States.
