FOUR people died and three were injured when a construction crane on the new Google Seattle campus collapsed in Seattle, the United States, on Saturday, pinning six cars underneath.

One female and three males were dead by the time firefighters got to the scene, Fire Chief Harold Scoggins said. He said two of the dead were crane operators and the other two were people who had been in cars.

A 25-year-old mother and her 4-month-old daughter as well as a 28-year-old man were taken to Harborview Medical Center, according to Seattle Fire spokesman Lance Garland. A fourth person was also injured and treated at the scene.

Harborview spokeswoman Susan Gregg said Saturday evening that the mother and baby would be discharged, while the man injured was in satisfactory condition.

The King County Medical Examiner’s Office said it would not release names of people who died until today.

The crane collapsed near the intersection of Mercer Street and Fairview Avenue near Interstate 5 shortly before 3:30 p.m., Scoggins said.

With Amazon and other tech companies increasing their hiring in Seattle, the city has dozens of construction cranes building office towers and apartment buildings. As of January, there were about 60 construction cranes in Seattle, more than any other American city.

Scoggins said officials do not yet know the cause of the collapse.  (SD-Agencies)
