Another week of searching the remains of a Kingdom Road home in which two adults died and the fate of two children is undetermined turned up little evidence, Sheriff Randall Boyce said Friday.
A few bones were found by a team of 10 to 12 agents from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives, Boyce said, but they were "unsure what the bones were." The ATF is a division of the U.S. Department of Treasury.
"They were packing up and leaving today," Boyce said.
The agents spent the week going piece by piece through charred items and sifting through ashes. Representatives of various federal, state and local agencies and two university forensic departments have been painstakingly inspecting and re-inspecting the pile of rubble for three weeks since the Sept. 23 fire.
Chloie Leverette, 9, and her brother, Gage Daniel, 7, are thought to have been in the home in which they lived with their grandparents, Leon "Bubba" McClaran Sr. and wife Molly McClaran, who have been declared dead after partial remains were recovered.
No signs of the children have been found, leading the Tennessee Bureau of Investigation to issue a regional Amber Alert. The TBI at one point said the children were not in the home but has also said they have no leads or evidence they were anywhere else.
