A Florida man remained missing and was feared dead after a 100-foot sinkhole swallowed his bedroom.

The 36-year-old man was in bed at his home in Tampa when the sinkhole swallowed everything. The man’s brother said he heard a crash around 11 p.m. on Thursday, and heard him screaming for help before he disappeared into the sinkhole.

"When he got there, there was no bedroom left," Hillsborough County Fire Rescue spokeswoman, Jessica Damico, told the AP. "There was no furniture. All he saw was a piece of the mattress sticking up."

The unidentified man's brother said he tried to help him before dialing 911.

A deputy sheriff who was first on the scene pulled out the missing man’s brother from the collapsing house.

"He basically just reacted and did what he had to do to get that person out," Lt. Donald Morris, of the Hillsborough County Sheriff’s Office, told WFLA.com.

Neighbors who live near the house where the sinkhole opened were evacuated as a precautionary measure.

"We put engineering equipment into the sinkhole and didn't see anything compatible with life," Damico said, adding the sinkhole was about 30 feet wide. "The entire house is on the sinkhole."

Lt. Morris said, "It's the only one we've seen that opened up in this manner; there is no evidence of the structure cracking or anything like that on the outside of the house.”
