Austin was never indicted in Bobo's death but two other men are still facing charges.

In March 2014, 29-year-old Zach Adams was charged with first degree murder and especially aggravated kidnapping.

Adams brother, John Dylan Adams, told police that he witnessed Bobo alive with his brother at the home they share following her abduction.

The remains were found several months after his arrest in a wooded area approximately 15 miles from Adams' residence.

In April, Adams' friend, 39-year-old Jason Wayne Autry, was also charged with especially aggravated kidnapping and first-degree murder.

Holly Bobo disappeared in April 2011 from her family home in Tennessee. She was last seen alive by her brother walking into the woods outside her home with a man wearing camouflage.

Three years after she went missing, Bobo's skulls and bones were found in northern Decatur County, Tennesse.

At least six men were arrested in relation to the death of Bobo but only two were charged.

Austin was initially offered immunity in exchange for information regarding the location of Bobo's body.

The agreement, however, was withdrawn after Austin was unable or unwilling to lead them to the body.

Court records showed that prosecutors were planning to indict Austin because of his being untruthful with investigators.
