>> hole in florida . it's a heartbreaking story. one man is presumed dead after his bedroom sank into the ground. and attempts to find him are on hold because authorities fear the entire house could collapse. gabe gutierrez is in seffner, florida , near tampa, with the latest good morning.
>> reporter: the sink hole is deepening and investigators are having a tough time getting inside the home. so far they've been unable to figure out what caused it. this scene is right out of a horror movie. the frantic 911 call came late thursday night.
>> okay, what happened to the house?
>> um, the bedroom floor just collapsed and my brother-in-law is in there. he's underneath the house.
>> a man had been in his bed inside this home near tampa. the next moment, he was gone. swallowed by a sink hole about 30 feet wide and more than 20 feet deep.
>> it's unreal. i don't believe it's real.
>> reporter: the victim, identified by family members as 36-year-old jeff bush. a landscaper.
>> great guy. there were times when he pedalled his bike all day long to get a job. and he just wanted to help somebody else.
>> reporter: this time, others did what they could for him. his brother was inside the house, heard the crash and jumped in the hole to rescue jeff .
>> and i couldn't get him. all i could hear -- i thought i could hear him screaming for me, hollering for me. help me. i couldn't do nothing.
>> reporter: then came a sheriff and he was able to pull the brother to safety but no sign of jeff .

>> reporter: and engineers say they might have to demolish the small house even though from the outside it looks like nothing happened, erica?
>> what a story. gabe, thank
