Engineers work in front of a home where sinkhole opened up underneath a bedroom and swallowed a man Friday, March 1, 2013, in Seffner, Fla. Jeff Bush screamed for help and disappeared as a large sinkhole opened under the bedroom of his house, his brother said Friday. Jeremy Bush told rescue crews he heard a loud crash near midnight Thursday, then heard his brother screaming.  There's been no contact with Jeff Bush since then, and neighbors on both sides of the home have been evacuated. (AP Photo/Chris O'Meara)
