Florida Sinkhole Swallows Bedroom with Sleeping Man, 'Sounded Like a Car Hit My House' [VIDEO]

A Florida man disappeared into a massive sinkhole of 30-foot-wide, 20-foot-deep that opened beneath his bedroom and swallowed up the bedroom portion of his Tampa home Thursday night, according to police.

The 36-year-old man's brother Jeremy Bush told rescue crews that he heard a loud crash around 11 p.m. then heard his brother screaming for help.

"[The family] heard a sound that they described as a car crash emanating from the bedroom in the back of the house," Hillsborough County Fire Chief Ron Rogers said at a news conference today.

Family members went to the room where Jeff Bush was sleeping according to ABC News' Tampa affiliate WFTS-TV.

"All they could see was part of a mattress sticking out of the hole. Essentially, the floor of the room had opened up," Rogers said. "They could hear the nephew in the hole, but they could not see him."

Janell Wheeler told the Tampa Bay Times she was inside the house when the sinkhole opened.

"It sounded like a car hit my house," she said.

Bush and three other people, including a small child were able to evacuate from the home however there were no signs of Jeff Bush.

"We put engineering equipment into the sinkhole and didn't see anything compatible with life," Hillsborough County Fire Rescue department spokeswoman Jessica Damico said.

Damico says Bracken Engineering officials determined the home's bedroom is the center of the sinkhole.

Early Friday officials with the fire rescue department determined it was too dangerous to try and check the home, unstable to continue rescue efforts.

"Right now, the potential for a collapse is very, very high," Damico added.

"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."

Police ordered an evacuation to the other residents from the structure, as well as the two surrounding homes.

The Florida Department of Environmental Protection said that sinkholes are common in Florida.
