Startling surveillance footage captured the moment a tree crashed onto a Maryland home last week, all while two teens were inside watching TV. The video shows the two teen girls sitting in the living room with their little chihuahua, Gizmo. Ironically, the girls were home from school because of bad weather and high winds. A large tree can be seen falling. And suddenly, it crashes through the home's roof, coming down on top of the girls. "I was floored. I was shocked," mom Jennifer Stone said.
