A federal trial for the man who fatally shot 11 people at a Pittsburgh synagogue approached its conclusion Friday as the defense, trying to persuade a jury to spare his life, pressed its case that mental illness spurred the nation’s deadliest antisemitic attack. Robert Bowers, a 50 year-old truck driver from suburban Baldwin, was convicted in June on 63 criminal counts for the 2018 massacre at Tree of Life synagogue. The jury has been hearing testimony in the penalty phase of the trial and will decide whether Bowers will receive the death penalty or life in prison without parole.
