Zachary Adams, 29, is charged with aggravated kidnapping, first degree murder, and coercion of a witness in the Holly Bobo case.
Holly Bobo disappeared from her Decatur County home on the morning of April 13, 2011.
John Adams is jailed in Obion County on federal weapons charges.
NASHVILLE, Tenn. -
The man charged with the 2011 kidnapping and murder of nursing student Holly Bobo tried to threaten his brother, according to an arrest warrant obtained by News 2 Wednesday.
The document, an affidavit for coercion of witness filed Tuesday, states Zachary Adams tried to get a message to his brother, John Adams, who is in custody in the Obion County jail, through another inmate.
Adams, 29, reportedly said to the inmate, "Tell my brother he is the one who started all this s#%t and if he don't [sic] shut his mouth, he will be in the hole beside her."
He made the alleged statement to the inmate on March 4, the day before he was indicted in the Bobo case.
At the time, Adams thought the inmate was going to be transferred to the Obion County jail.
The inmate ultimately reported his conversation to the Tennessee Bureau of Investigation. A second inmate who overheard the conversation and corroborated the incident to a special agent.
In the affidavit, the TBI says Adams was attempting to coerce or influence a witness in the judicial proceeding involving the Bobo case.
Coercion of a witness is a Class D felony.
"The TBI takes this sort of thing very seriously," spokesman Josh DeVine said. "Coercion of a witness is not something we take lightly."
DeVine continued, "In a case like this where we have spent countless man hours and countless resources in investigating this case, we are not going to do anything or allow anyone to jeopardize the status of that investigation."
The TBI did not say if John Adams, 25, knew about the threat his brother is accused of trying to send.
He is being held in the Obion County jail on federal weapons charges he pleaded guilty to last December.
John Adams has a lengthy criminal history with arrests for possession of methamphetamine, multiple arrests for theft over $1,000 and public intoxication.
Zachary Adams pled not guilty to charges of first degree murder and especially aggravated kidnapping in the disappearance and death of Bobo last month.
Bobo disappeared from her home on Swan Johnson Road in Decatur County on the morning of April 13, 2011.

A status hearing is scheduled for April 9.
