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 said through tears Friday in a neighbor's yard. "But I just couldn't do nothing.''
He added, "I could swear I heard him hollering my name to help him.''
Officials lowered equipment into the sinkhole and saw no signs of life, said Hillsborough County Fire Rescue spokeswoman Jessica Damico.
