The Hillsborough County Sheriff's Office is conducting the investigation. Detective Larry McKinnon said the sheriff's office and the county medical examiner cannot declare Bush dead if his body is still missing. Under Florida law, Bush's family must petition a court to declare him deceased.
"Based on the circumstances, he's presumed dead; however the official death certificate can only be issued by a judge and the family has to petition the court," McKinnon said.
The area around Seffner is known for sinkholes due to the geography of the terrain, but they are rarely deadly. No one — from longtime public safety officials to geologists — could remember an incident where a person was sucked into the earth without warning.
