PITTSBURGH (AP) — A steady stream of people have been stopping by the closed Pittsburgh synagogue that one year ago was the scene of the deadliest attack on Jews in U.S. history. Lining the fence outside the Tree of Life synagogue stand 11 flowerpots, each bearing one of the names of a person killed in the attack, which also wounded seven others. People have also been piling bouquets and crocheted hearts and hanging signs on the fence.
