SEFFNER, Fla. -

 Engineers are headed back to the site of Florida sinkhole to do more tests on the unstable and dangerous ground that swallowed a man in his bedroom.
   The engineers are expected to resume their work after sunrise Saturday on what they have described as a slowly growing sinkhole.
   They have already determined that the soil around the home is very soft and they believe the entire house could eventually be devoured by the sinkhole.
   Thirty-seven-year-old Jeff Bush was in his bedroom Thursday night when the earth opened and swallowed him and everything else in his room. Five other family were in the house but escaped unharmed. Bush's brother jumped into the hole to try to help, but he had to be rescued himself by a sheriff's deputy.
