A second suspect has been charged in the tragic case of Holly Bobo, a 20-year-old nursing student who disappeared from her family's home in Darden, Tenn. in 2011.

According to WSMV in Nashville, Jason Wayne Autry, 39, has been charged with especially aggravated kidnapping and first-degree felony murder in Bobo's case. He is already in prison for a previous assault charge.

Bobo, cousin to country singer Whitney Duncan, disappeared on April 13, 2011. Zachary Adams was charged with first degree felony murder and especially aggravated kidnapping in the case in March, almost three years after her disappearance.

Duncan reacted on Twitter after news of the new charges broke on Tuesday (April 29).

Autry and Adams are known to be friends. Adams' brother, who plans on testifying against him during the trial, claims he saw Bobo alive in their home the day she disappeared. Bobo's brother saw her being led into the woods by Adams the morning of her disappearance.

WSMV also reports that a third suspect, Shayne Kyle Austin, will also be charged in the case. Austin had originally signed an immunity agreement in exchange for testimony against Autry and Adams, but the district attorney says the immunity agreement is no longer valid, because Austin lied about his testimony. His specific charges have not yet been released.

Bobo's family remain grief-stricken over their loss.

"Words can't describe the heartbreak," Duncan tweeted following the devastating news. "Thank u for the prayers."

Autry and Adams are both scheduled to be in court today (April 30). Adams also faces an additional charge of coercion of a witness.

Our thoughts and prayers continue to go out to the Bobo family.
