Crews on Monday morning started demolishing the remains of a six-story apartment building in Davenport, Iowa, that partially collapsed more than two weeks ago, killing three people and leaving dozens homeless.
Workers were using a large excavator to dismantle the 116-year-old brick, steel and concrete structure in a process officials said would take several weeks. It's a difficult task because the building is in the heart of the city's downtown and is believed to contain asbestos and other potentially hazardous material.
