(ABC NEWS)-- The Hillsborough County Sheriff's deputy who first responded to the Seffner Sinkhole said when he entered the house, he could see the hole growing as he watched.

"When I turned in the bedroom the only thing that I saw was a hole, and the hole took the entire bedroom," said Douglas Duvall. "You could see the bed frame, the dresser. Everything was sinking."

Inside the hole was Jeremy Bush, who was desperately digging in the dirt, trying to find his brother. Jeff Bush was pulled under when the hole first opened up underneath their house.

Duvall said when he realized the hole was not stable, he told Bush they needed to get out of the house.

"It was kind of like sticking your hand into the floor," Duvall explained. "I got Mr. Bush by his hand and pulled him out."

An emotional Jeremy Bush said that he was doubtful his brother survived being buried underground.

"I know in my heart he's dead. But I just want to be here for him because I love him," Bush said.

Initially, the family inside the single story house thought they heard a car crashing into the structure. In reality, it was the inside of the house crashing through the newly created empty space underneath. That's where Jeff Bush was pulled under.

"I heard my brother screaming," Bush said. "So I ran back there and tried going inside his room," he said. That's when he realized that the room was gone.

Bush said he asked for a shovel, and jumped into the hole, looking for his brother.

"I just started digging and started digging," Bush said. "The cops showed up and pulled me out of the hole and told me the floor was still falling in."

Since both Duvall and Bush escaped from the house, it's been condemned as an emergency, and no further rescue efforts have been allowed until it's stabilized.

That frustrated some of Bush's relatives, who wondered why no one was going inside to find Bush.

"They are professionals. This is what they do," said Mike Merrill, Hillsborough County's Administrator. He said while rescuers might want to risk going back into the home, they also know it could make the situation worse.

"They know when to stop," Merrill said.
