Pittsburgh synagogue gunman's mental health debated in death penalty trial.

Lawyers for Robert Bowers, the gunman convicted in the deadliest antisemitic attack in US history, argued that he is mentally ill and unable to understand the world or make appropriate decisions. Bowers was convicted this month in the 2018 killings of 11 worshippers at a Pittsburgh synagogue, and prosecutors are seeking the death penalty. The defense argues that Bowers was unable to form the requisite level of intent to allow the jury to impose a death sentence. The penalty phase of the trial is expected to last four to five weeks.
