Seffner , Florida ( CNN ) -- Authorities in Florida gave up the search Saturday for a man presumed dead after a sinkhole opened beneath the bedroom of his family 's suburban Tampa home , swallowing him up . The effort to recover the body of Jeff Bush had resumed earlier in the day after authorities stopped operations overnight , saying the hole was still expanding and the house could collapse at any time . `` We just have not been able to locate Mr. Bush and so for that reason the rescue effort is being discontinued , '' Mike Merrill , county administrator for Hillsborough County , told reporters Saturday evening . `` At this point , it 's really not possible to recover the body . '' Merrill said the next phase in the effort would be demolition of the family 's home , which is scheduled to begin Sunday and could take a couple of days . He stressed that workers were dealing with a `` very unusual sinkhole '' -- deep , wide and extremely unstable . `` We 've done everything we believe that we can . We wish we could have done more , '' Merrill said . The sinkhole was between 50 and 60 feet deep , he said . The terror for the Bush family began Thursday night , as everybody in the blue , one-story , 1970s-era home in Seffner was going to bed . There was a deafening noise . `` I ran toward my brother 's bedroom because I heard my brother scream , '' Jeremy Bush , Jeff Bush 's brother , told CNN 's `` AC360 . '' Sinkholes common , costly , sometimes deadly . `` Everything was gone . My brother 's bed , my brother 's dresser , my brother 's TV . My brother was gone . '' Bush frantically tried to rescue his brother , by standing in the hole and digging at the rubble with a shovel until police arrived and pulled him out , saying the floor was still collapsing . `` I could n't get him out . I tried so hard . I tried everything I could , '' he said through tears . `` I could swear I heard him calling out . '' The terror of those moments can be heard in a recording of the 911 call in the moments after the sinkhole opened up . `` The house just fell through , '' a female voice says on the recording released Friday by the Hillsborough County Sheriff 's Office . The woman asks for an ambulance and the police . `` The bedroom floor just collapsed , and my brother-in-law is in there . He 's underneath the house , '' she says . Jeremy Bush and four other people , including a 2-year-old child , were uninjured . After officials called off the search for his brother Saturday , Jeremy Bush spoke to Bay News 9 . `` It 's very hard . It 's not just I lost my brother . They 're so many memories in this house , '' he told the CNN affiliate . `` I do n't know what we 're going to do . '' Nearby homes were evacuated Friday as a precaution . The sinkhole compromised a house next door to the Bush home , fire department spokesman Ronnie Rivera said . That home was n't damaged as of Saturday morning , but the family that lives there was given up to 30 minutes to remove some belongings before abandoning the premises , he said . Merrill said residents on either side of the Bush home were allowed to go into their houses a short time to retrieve what they could . Sinkholes are common in the state , according to the Florida Department of Environmental Protection . The state lies on bedrock made of limestone or other carbonate rock that can be eaten away by acidic groundwater , forming voids that collapse when the rock can no longer support the weight of what 's above it . Hillsborough County , on Florida 's west coast , is part of an area known as `` sinkhole alley '' that accounts for two-thirds of the sinkhole-related insurance claims in the state , according to a Florida state Senate Insurance and Banking Committee report .

Carter , Jake Carpenter , Brian Carberry , Elwyn Lopez , Nick Valencia and Tina Burnside contributed to this report .
