A 15-story construction crane being lowered to safety in a snow squall plummeted onto a Lower Manhattan street Friday, killing a Harvard-educated Wall Street worker and leaving three people hurt by the debris scattered by the rig’s lengthy boom. The accident occurred in the City’s TriBeCa district, a section of town that has become fashionable in recent years and is being redeveloped. TriBeCa stands for Triangle Below Canal (Street).
