In an interview with The Associated Press on Tuesday, Teresa Mayes' sister, Bobbi Booth, said her sister told her last week that she knew about the killings, but Booth thinks Teresa Mayes may have been too scared to call the police.
"Teresa started to call, text and Facebook constantly on Thursday," Booth said.
Booth told Teresa Mayes to call the police and was assured that she had, but by Saturday Booth had become suspicious about that claim and called police herself.
"I told them exactly what she had told me: Who the bodies were, where they could be dug from," Booth said.
As it turned out, investigators had begun digging in the Mayes' backyard the previous day.
Tennessee Bureau of Investigation spokeswoman Kristin Helm said she was unaware of Booth calling about the killings but said she might have called a different law enforcement agency
