NYC Parking Garage Collapse: Demolition Planned for Complex Operation.

The Manhattan district attorney's office will investigate the partial collapse of a parking garage that killed one and injured five others. The building, which was built in 1925, had four active violations, according to records from the New York City Department of Buildings. The exact cause of the collapse remains under investigation, but a focus is on the weight of the vehicles parked on the roof and the age of the building. Emergency responders are working to safely demolish the building while also removing the vehicles.
