Crews searching for survivors in deadly NY buildling collapse

Live look here in Brooklyn, New York, where the number of deaths continues to climb after a building collapsed last night. We know at least eight people have died, 17 others injured, including seven children. Apparently right now we're looking at the bottom of a helicopter. But just after 4 o'clock Eastern time yesterday, the three-story building partially fell into an open construction site next door in Brooklyn's Flatbush neighborhood. The department says that several children were in the building when it fell. It is not clear how many people are still missing and fire crews say the search effort is proving to be a challenge because the collapsed building shared a wall with another building. It's a very unstable situation. The adjoining building that remains partially intact is always a danger. Our main concern is a secondary collapse. Now that building was home to at least one business on the ground floor with apartments on the upper floors. Construction workers apparently doing excavation at the neighboring site at the time of the collapse. The cause is under investigation.
