[The University of Pittsburgh Police pushed a Pitt ENS alert to students and faculty](https://www.pittwire.pitt.edu/pittwire/features-articles/see-archive-student-reactions-tree-life-massacre) ordering them to avoid the Squirrel Hill/Shadyside corridor, many Pitt students lived in or walked through Squirrel Hill on weekends. The Tree of Life shooter, Robert Gregory Bowers, killed 11 worshippers in the deadliest antisemitic attack in U.S. history. Pitt issued no campus lockdown (the synagogue was outside the immediate campus perimeter); the ENS bulletin instead directed the campus community to avoid the Squirrel Hill/Shadyside corridor.",
    "outcome": "Robert Gregory Bowers, 46, killed 11 congregants and wounded 6 others including 4 responding police officers at the Tree of Life building. He was shot multiple times by police and arrested at the scene. The University of Pittsburgh sustained no direct campus casualties, but multiple Pitt students, faculty, and community members were members of the affected congregations (Tree of Life - Or L'Simcha, New Light, and Dor Hadash). Pitt cancelled non-essential university activities for the remainder of Saturday and issued community-support messaging through the following week. Bowers was convicted on all 63 federal counts in 2023 and sentenced to death.",

  "context": "[The University of Pittsburgh](https://en.wikipedia.org/wiki/University_of_Pittsburgh) is a public R1 research university in the Oakland neighborhood of Pittsburgh, less than two miles northwest of the Squirrel Hill neighborhood where the [Tree of Life - Or L'Simcha Congregation synagogue](https://en.wikipedia.org/wiki/Pittsburgh_synagogue_shooting) is located. At 9:54 AM EDT on Saturday, October 27, 2018 (Shabbat morning) Robert Gregory Bowers, 46, entered the synagogue armed with an AR-15-style rifle and three handguns and opened fire on worshippers from three congregations sharing the building: Tree of Life - Or L'Simcha, New Light, and Dor Hadash. He killed 11 people and wounded 6 (including 4 responding police officers) in what remains the deadliest antisemitic attack in U.S. history. The [Pitt Emergency Notification Service (ENS)](https://www.safety.pitt.edu/subscribe-alerts) pushed an alert reading 'Shots fired at the Tree of Life Synagogue on Wilkins Ave. Police operations are ongoing. Avoid the Squirrel Hill/Shadyside area', preserved [verbatim by The Pitt News in its retrospective coverage](https://pittnews.com/article/151986/news/the-tree-of-life-massacre-what-happened/). [Carnegie Mellon University, located adjacent to Pitt in Oakland, simultaneously placed its campus on lockdown](https://www.cmu.edu/leadership/the-provost/campus-comms/2018/2018-10-27.html) and cancelled all university-sponsored activities. Pitt's response was notable for using ENS as a neighborhood-information channel rather than a campus-lockdown trigger, the synagogue was nearly two miles away, but many Pitt students lived in or walked through Squirrel Hill on weekends. Because the shooting occurred at a private synagogue off Pitt's campus rather than a dangerous situation 'occurring on the campus,' the language of Clery's emergency-notification trigger (34 CFR 668.46(g)), Pitt's use of the ENS channel here reflects an institutional choice to push a precautionary community-safety bulletin for a nearby off-campus threat, not a strict on-campus regulatory obligation. Pitt's Oakland campus remained operationally open while the university channeled community support resources to grieving students, faculty, and staff in the days that followed. Bowers was [convicted on all 63 federal counts on June 16, 2023](https://www.justice.gov/archives/opa/pr/jury-recommends-sentence-death-pennsylvania-man-convicted-tree-life-synagogue-shooting) and sentenced to death.",
