Misty's grandmother, Flora Hollars, who lives in Tennessee, said she thinks as long as she and her brother, Hank, are in jail, they won't tell what they know about Haleigh.
"I believe they'll do more talking out of jail," Hollars said in a phone interview Monday. "Look at how long it's been. They ain't said nothing."
Misty and Hank's mom and dad were also recently arrested and are in jail on drug charges. Hollars said with the entire family in jail, the chances of them talking are slim to none.
"I don't think they'll say anything as long as they're in jail," Hollars said. "If they were out, they might talk."
Hollars said she still believes Haleigh's body was dumped into the St. Johns River, and in her opinion, everyone in the Croslin family knows more than what they've admitted to.
"Misty is the one that told me they wrapped her in a bag and tied it with a yellow rope and dropped her into the St. Johns River," Hollars said.
Even with little to no physical evidence, deputies are treating Haleigh's disappearance as a homicide, and they're likely hoping that one of the Croslins will eventually crack while in jail.
"I think Ronald knows more than he's saying, too," Hollars said.
