A tower crane being dismantled collapsed Saturday, April 27 in Seattle, killing four people, including two ironworkers on the crane and two bystanders on the street below. The jobsite, located in a Google office development in Seattle's bustling South Lake Union neighborhood, is adjacent to a busy intersection where traffic had not been blocked off during the crane’s disassembly. It is the first fatal crane accident in the Puget Sound region since a crane collapse in Bellevue, Wash., in 2006 that killed one person.
