PITTSBURGH (AP) — Seedlings from the 9/11 survivor tree will be donated and planted in Pittsburgh as a memorial for a mass shooting at the Tree of Life synagogue that killed 11 people. The Callery pear tree was nursed to health after being found in the rubble after the Sept. 11 terrorist attacks. It’s now located at the Sept. 11 Memorial. The nonprofit that runs the memorial began to send out seedlings in 2013 to areas affected by violence or disaster.
