SEFFNER, Fla. (AP) — The effort to find the body of a Florida man who was swallowed by a sinkhole under his Florida home was called off Saturday and crews planned to begin demolishing the four-bedroom house.

The 20-foot-wide opening of the sinkhole is almost completely covered by the house and rescuers feared it would collapse on them if they tried to search for Jeff Bush, 37. Crews were testing the unstable ground surrounding the home and evacuated two neighboring homes as a precaution.

Hillsborough County Administrator Mike Merrill said heavy equipment would be brought in to begin the demolition Sunday morning.
