NASHVILLE, Tenn. - The man accused of abducting and murdering Holly Bobo will be formally charged Tuesday, reports CBS affiliate WTVF.

Zachary Adams, 29, is set to appear at the Decatur County courthouse for his arraignment. He is expected to enter a plea and will likely be appointed a public defender. He is currently being held without bond at the Chester County jail.

Adams was arrested on an unrelated assault charge Friday, Feb. 28 following a search of his home by the Tennessee Bureau of Investigation in connection with the Bobo case. He was indicted by a Decatur County grand jury last Wednesday on especially aggravated kidnapping and first-degree felony murder.

Holly Bobo disappeared on April 13, 2011, when her brother told authorities he saw the 20-year-old woman following a man in hunting clothes into the woods near the family home in Darden, Tenn. That was the last time anyone has reported seeing her. Police searched exhaustively but were unable to find her.

Investigators have not revealed what evidence they have against the suspect, or if they have found any remains of the victim. District Attorney General Hansel McCadams says he's confident in the case.

"Based upon the evidence that we have before us, we also feel that she was killed in the perpetration of that kidnapping," said McCadams. "This case will be evaluated by my office as a death penalty-eligible case. The evaluation process will review the nature of the crime, the criminal history of the defendant, the aggravating factors set up by statute, and mitigating factors."

The motives and circumstances of Holly's disappearance are still being investigated, and there is still the possibility that additional suspects exist, according to officials.
