A Florida man fell into a sinkhole that opened suddenly Thursday night beneath the bedroom of his suburban Tampa home, calling out to his brother for help as he fell, the brother said Friday.Bush frantically tried to rescue his brother, Jeff Bush, 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.

What began with hopes of rescue turned into a body recovery operation after monitoring equipment failed to detect any signs that Jeff Bush survived the fall into the hole, according the Hillsborough County Sheriff’s Office.Rescuers still hadn’t gone into the hole — it’s too dangerous, Fire Chief Ron Rogers told reporters. Authorities say they worry the hole is still spreading and the house could collapse at any time. The sinkhole is about 20 feet to 30 feet across and may be 30 feet deep, said Bill Bracken, president of an engineering company assisting emergency workers. The hole was originally reported to be 100 feet across, but that is the diameter of the safety zone surrounding it, Bracken said. “It started in the bedroom, and it has been expanding outward and it’s taking the house with it as it opens up,” he said.Check out images of the sinkhole house Nearby homes have been evacuated as a precaution, Rogers said.Damico said about 40 police and firefighters were standing by at the scene Friday morning. Meanwhile, engineers hope to use more sophisticated equipment to get a three-dimensional image of the sinkhole. Family members were also on hand, waiting out what they feared would be a devastating day. “I know in my heart he’s dead,” Jeremy Bush said. “But I just want to be here for him, because I love him. He was my brother, man.”Sinkholes are common in Florida, 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 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.
