The 2018 Tree of Life synagogue attack in Pittsburgh

26 October 2026

Historical background

On 27 October 2018, an antisemitic extremist attacked worshippers gathered for Shabbat services in the Squirrel Hill neighborhood of Pittsburgh. Eleven Jewish people were murdered and several others were wounded. Three congregations—Tree of Life, Dor Hadash and New Light—used the synagogue building. The victims were individuals with families, friendships and distinct roles in the local Jewish community, not anonymous figures in a crime statistic.

Community and turning points

The United States Department of Justice established that the attacker had expressed violent antisemitic beliefs. A federal jury convicted him of dozens of offences, including hate crimes resulting in death, and in 2023 he was sentenced to death. The criminal case concerned both the killings and the obstruction of religious exercise. Reporting should distinguish the court's established findings from public speculation and should avoid reproducing extremist propaganda unnecessarily.

Evidence and public memory

Pittsburgh residents and Jewish organizations developed memorial services, mutual-aid initiatives and long-term projects dedicated to the people killed. The October 27 Archive at the Heinz History Center preserves community responses and evidence of the aftermath. The attack has become a major reference point for conversations about synagogue security, religious freedom and the social consequences of antisemitism. Remembering the victims requires attention to the living community as well as the violent event.
