Nearly three years after nursing student Holly Bobo disappeared from her family's home in Darden, Tenn., a suspect has been indicted for her kidnapping and murder.

According to WKRN in Nashville, a grand jury in Decatur County returned a sealed indictment against 29-year-old Zachary Adams on Wednesday afternoon (March 5), charging him with first degree felony murder and especially aggravated kidnapping.

The news comes just days after investigators executed search warrants in multiple locations in and around Holladay, Tenn. on Friday (Feb. 28), including Adams' property. Adams was arrested for aggravated assault on Friday, just two days after making bail on an unrelated drug charge.

Bobo was last seen by her brother, Clint, walking into the woods with a man dressed in camouflage. He mistook the man for her boyfriend and did not realize she was being kidnapped.

Her family had never given up hope for her safe return. Bobo's cousin, country singer and 'Survivor' star Whitney Duncan, tweeted to ask for prayers as investigators executed their search warrants on Friday.

Adams was already in custody on the assault charges. He is being held without bond.
