A Florida man has disappeared into a 20ft-deep (6m) sinkhole
that swallowed up a bedroom in his house.
Jeffrey Bush, 36, is presumed dead after rescue crews failed to
make contact with him.
Officials in the town near Tampa have postponed further rescue
efforts until they determine how much of the ground under the house is
compromised.
Sinkholes are common in certain parts of Florida, Hillsborough
County's fire chief said.
"Florida essentially sits on a system of caverns,"
Chief Ron Rogers said, saying water erosion in the caverns causes them to
collapse and sinkholes to form on the surface.
