NEW YORK (AP) — A pedestrian killed by a collapsing crane was eulogized Sunday as a man of kindness and generosity as the final remnants of the crumpled steel were removed from the Manhattan street where they fell. David Wichs, 38, has been described by relatives as a mathematical whiz who graduated from Harvard University and worked at a computerized-trading firm. The recipients included the Yeshiva of Flatbush, which had welcomed Wichs as a 14-year-old from Prague who barely spoke English and knew no Hebrew.
