DECATURVILLE, Tenn. (AP) - A Benton County man has pleaded not guilty to murder and kidnapping charges in the disappearance of 20-year-old nursing student Holly Bobo.
Thirty-nine-year-old Jason Autry was indicted by a specially called grand jury on Tuesday and entered his plea on Wednesday in Decatur County.
Zachary Adams also faces murder and kidnapping charges.
The 29-year-old Benton County man pleaded not guilty to those charges in March. On Wednesday he pleaded not guilty to an additional charge of coercion of a witness.
Meanwhile, a third man could face charges in the case after prosecutors revoked an immunity agreement. Court records show 29-year-old Shayne Austin of Decatur County agreed to lead investigators to Bobo's body.
They later revoked the agreement, claiming Austin was not truthful. Bobo's body has not been found.
Prosecutors plan to indict at least one more person in the Holly Bobo case, according to documents obtained today by The Jackson Sun.
According to the documents, prosecutors plan to indict Shayne Kyle Austin, who previously had been granted immunity in exchange for his cooperation in the investigation.
The state voided the immunity agreement because Austin was not completely truthful and forthcoming, according to an email from Assistant District Attorney General Beth Boswell to Austin's lawyer, Luke Evans. The email was sent on March 27.
"When we indict your client, I will give you a courtesy call informing you," Boswell told Evans in the email.
The Jackson Sun went to an address listed for Austin on whitepages.com, but the property was enclosed in a fence, and the driveway was blocked by a locked gate. The listing did not include a telephone number. Evans did not respond to a telephone message left at his office seeking comment.
Austin would be the third person indicted in the abduction and killing of Bobo. Jason Wayne Autry was indicted today on charges of first-degree murder and especially aggravated kidnapping. Zachary Adams was indicted on the same charges in March.
Bobo was abducted from her home in Darden in April 2011.
Boswell's email indicating the intent to indict Austin was included with documents filed by Austin's lawyer in Decatur County Chancery Court on April 1. The documents seek a restraining order and temporary injunction to keep prosecutors from violating the immunity agreement and indicting Austin.
According to the documents, Austin received immunity in the Bobo investigation in an agreement signed on March 6. The agreement gave Austin immunity from any criminal charges arising from the Bobo case.
More specifically, the agreement said, "In exchange for the total cooperation of Shayne Kyle Austin, the State agrees to grant him immunity for all charges arising out of the disposal, destruction, burial and/or concealment of Holly Bobo's deceased body, conditioned upon him assisting us in recovering the body of Holly Bobo."
The immunity agreement said the state would also not charge Austin with tampering with evidence or accessory after the fact "if he was present for, if he participated in, of (sic) if he has information concerning the disposal, destruction, burial, and or concealment" of Bobo's body or other items of evidence connected to or belonging to her.
The agreement also said the state would give Austin immunity for information concerning the "possession of any controlled substances, the sale of any controlled substances, the possession of drug paraphernalia, and/or any other drug related criminal activity (not to include any drugs administered to Holly Lynn Bobo.)"
The agreement was contingent upon Austin being "completely truthful, forthcoming and cooperative" in the investigation. The agreement was also void if investigators independently developed evidence or witnesses — other than any co-conspirators — that implicated Austin in a crime related to the Bobo case.
The immunity agreement had been signed by Boswell, Evans, Austin and Russ Winkler, assistant special agent in charge of the Tennessee Bureau of Investigation.
A second suspect was charged with murder in the case Tuesday afternoon. Jason Autry, 39, faces indictments for especially aggravated kidnapping and first-degree murder in the case.
Zachary Adams was arrested in connection with the case in February 2014 after police officers searched his home and property in Holladay, Tenn.
