The gunman accused of murdering 11 in a mass shooting at the Tree of Life synagogue in 2018 is now on trial in a federal courtroom in Pittsburgh. On 27 October 2018, Robert Bowers, then 46, entered the synagogue in the Squirrel Hill neighbourhood armed with three handguns, an AR-15 rifle, and a trove of magazines and ammunition. Inside, he opened fire on congregants in what marks the deadliest antisemitic attack in American history. Eight men and three women – aged from 54 to 97 – died in the massacre. After numerous delays, the now-50-year-old is finally standing trial for more than 60 federal charges including obstruction of free exercise of religion resulting in death and hate crimes resulting in death. During opening arguments on Tuesday, Mr Bowers’ attorneys admitted that he was responsible for the massacre but claimed that he acted on “an irrational motive” and had “misguided intent”. Prosecutors meanwhile pointed out that, in the months leading up the shooting, the suspect was spewing bigoted and antisemitic vitriol online. If convicted, he could face the death penalty.
