The man accused of committing the deadliest antisemitic attack in American history has been found guilty in the shooting deaths of 11 worshippers at the Pittsburgh Tree of Life synagogue in 2018.

Jurors returned a guilty verdict Friday after several hours of deliberating the case. They must next decide whether Robert Bowers’ fate will be death row or life in prison, in what is expected to be a lengthy penalty phase of the trial.

Bowers was charged with 63 criminal counts, including 11 counts each of obstruction of free exercise of religion resulting in death and hate crimes resulting in death. He was found guilty on all 63 counts. Some of the charges carry a potential death sentence.

Bowers, a 50-year-old truck driver from the Pittsburgh suburb of Baldwin, hated Jewish people, and turned a house of worship into a “hunting ground” on Oct. 27, 2018, when he fired about 100 rounds and took 11 lives, including many elderly people, federal prosecutors said during the trial.

Deadliest antisemitic attack in US history

Bowers was accused of driving to the Tree of Life synagogue in Pittsburgh’s Squirrel Hill neighborhood that morning and entering with multiple firearms, including an AR-15.

Several local congregations had gathered there to mark the Sabbath that day.

Police said Robert Bowers burst into the Tree of Life synagogue shouting “All Jews must die” as he opened fire on the congregants, killing 11 and injuring seven others, including five police officers who exchanged gunfire with him. Bowers was also hit by three bullets.
