A 911 call was made at 7:22 p.m. after two large pieces of a Manitowoc 4100 crawler crane — one 80 feet long and the other 40 feet — dislodged and crashed down, according to fire officials. "It started to vibrate — you just see the metals snap one by one. It shook the whole area," said witness David Tobin, 15. "It started to fall down. It was crazy. The metals just snapped."
