More than four years after 11 Jewish worshippers were fatally shot at the Tree of Life synagogue in Pittsburgh, jury selection got underway in the trial of a Pennsylvania man accused of carrying out the crime in 2018 and whether they would be capable of sentencing him to death.

U.S. District Judge Robert Colville thanked prospective jurors for their service, summarizing the case and describing the trial’s phases. Robert G. Bowers, a 50-year-old truck driver from the Pittsburgh suburb of Baldwin, sat with his attorneys and eyed documents as the judge spoke.

Prosecutors, defense attorneys and the judge spent about 30 minutes questioning the first four prospective jurors called. Most questions centered around the candidates’ willingness to impose the death sentence and, if so, whether they would be open to consider mitigating evidence, including about the defendant’s mental state or childhood.

All four said they could consider a sentence of death or life in prison.

One came out firmly in support of capital punishment, saying “there needs to be repercussions.” Another said a house of worship “should have been a safe place” and that she couldn’t imagine a worse crime. But she also said that after sitting behind Bowers during a previous hearing, she realized ”he’s a person, not a monster.”

The court plans to select 12 jurors and six alternates.

Bowers is charged with 63 counts and if convicted could get the death penalty, a sentence not used at the federal level since 2003. Former U.S. Attorney General William Barr reinstated capital punishment in July 2019.

The incident was the deadliest antisemitic attack in U.S. history.

‘An absolute tragedy’

Authorities say that on Oct. 27, 2018, Bowers drove to the synagogue in Pittsburgh’s Squirrel Hill neighborhood, where members of several local congregations had gathered to mark the Sabbath. There, they say, he entered the building carrying multiple firearms, including an AR-15 rifle and three handguns.
