The man who allegedly killed 11 people and wounded six others in an anti-Semitic attack on a Pittsburgh synagogue could face the death penalty, authorities said.

Authorities identified the suspect as Robert Bowers, 46, of Baldwin, Pennsylvania.

Police say the gunman entered the Tree of Life Synagogue in the Squirrel Hill neighborhood of Pittsburgh and shot people in each of the three congregations that was holding services in the building. He then reportedly barricaded himself in the third floor of the temple and engaged in a shootout with police before being taken into custody.
