Pittsburgh law enforcement officials are looking into a fake bomb threat that was recently made against the Tree of Life synagogue, the site of the deadliest antisemitic attack in American history.

In a statement to NBC News, a police representative confirmed that an email containing the threat was received last week but did not provide specific details, only noting that it appeared to be a “hoax in line with other similar threats against synagogues around the country.”

Pittsburgh’s Tree of Life synagogue was the scene of a horrific mass shooting on October 27, 2018, when gunman Robert Bowers entered the building armed with an AR-15-style rifle and opened fire on the congregation. Eleven worshippers were killed, and four police officers who responded to the scene were among the many injured.

Last August, Bowers was sentenced to death on 22 capital counts, along with 37 life sentences and an additional 80 years on four other charges.

In a move towards Jewish communal healing, a groundbreaking ceremony was held in late June for a new building at the site, which will feature a memorial and a museum dedicated to fighting antisemitism. Renowned architect Daniel Libeskind, famous for his designs of Jewish museums, Holocaust memorials, and partaking in the master plan for rebuilding the World Trade Center after 9/11, has been chosen to lead the project.

At the groundbreaking event, Second Gentleman Doug Emhoff spoke about the significance of combating antisemitism.

“Almost six years ago, a white supremacist committed the deadliest attack on American Jews in our nation’s history right here,” Emhoff said. “It was an unspeakable act of terror, of violence, barbarism, fueled by antisemitic hate.”

“When Jews are targeted because of their beliefs or identity, or when Israel is singled out because of anti-Jewish hatred, that is antisemitism and it must be condemned.”

Since the tragic shooting, much of the original synagogue complex had remained unused and has since been demolished to make way for the new memorial site.
