The Hillsborough County Sheriff's Office released the audio of the 911 call about the Seffner sinkhole.
In the emotional 42-second clip, you hear a woman who tells the operator, "The bedroom floor just collapsed and my brother-in-law is in there and he's underneath the house."
Jeff Bush, 37, was presumed dead after the concrete floor caved in about 11 p.m. Thursday as everyone in the house was turning in for the night. It gave way with a loud crash that brought his brother running.
Jeremy Bush said he jumped into the hole but couldn't see his brother and had to be rescued himself by a sheriff's deputy who reached out and pulled him to safety as the ground crumbled around him.
"The floor was still giving in and the dirt was still going down, but I didn't care. I wanted to save my brother," Jeremy Bush, 36, said through tears Friday in a neighbor's yard. "But I just couldn't do nothing."
