Trapped for hours below the rubble, a construction worker was pinned when a house collapsed right on top of him Monday afternoon in south Baltimore. Meghan McCorkell has more on the rescue mission. Investigators say a construction crew was working inside the house when the entire thing collapsed on top of them. For four hours, firefighters dug through feet of rubble, desperately trying to reach a man trapped in a house collapse. "You can see that the damage is pretty much the entire building is gone," said Capt. Jeff Long in Sky Eye Chopper 13.
