(Decatur County, TN) The Tennessee Bureau of Investigation will hold a news conference this afternoon to announce, “new and significant developments” in the Holly Bobo.

This morning, Zach Adams, who is charged with felony first degree murder and especially aggravated kidnapping in the Bobo case, was in court.

Aggravated assault charges against Adams, in a separate case, were dropped when the victim refused to testify.

We are told there is a special grand jury meeting this afternoon related to the Holly Bobo case.

Adams entered a not guilty plea to the Bobo charges.

Our Katie Rufener (@KRufener_WREG3) will be at the courthouse and at the news conference which we plan to stream live on digital-stage.wreg.com.

Adams is being held in the Chester County jail without bond.

It’s been three years since Holly Bobo disappeared.

It was April 13, 2011, when her brother told authorities he saw Bobo following a man in hunting clothes into the woods near the family home in Darden.

Police and family searched but were unable to find her.

Investigators have not revealed what evidence they have against the suspect, or if they have found a body.

Adams have a violent past and some say they are not surprised he was arrested.
