On Shabbat morning, October 27, 2018, a lone gunman broke into the Tree of Life synagogue in Pittsburgh during services, shot and killed 11 people, and injured 7 others as they worshiped.

During commemorative observances a year later, Monique Mead played her violin on the sidewalk outside the gate., as three youngsters attached a heart to the gate.
