FILE - In this April 27, 2019, file photo, fire and police crew members work to clear the scene where a construction crane fell from a building on Google's new Seattle campus, crashing down onto one of the city's busiest streets and killing four people. Washington state's Department of Labor and Industries released the results of its investigation into the collapse Thursday, Oct. 17, 2019. It found, as experts have long suspected, that the crane toppled because workers who were disassembling it had prematurely removed pins securing the sections of the crane's mast.
