Officials confirm remains are those of missing nursing student Holly Bobo

NASHVILLE, Tenn. (CNN) -- Remains found in rural Decatur County are those of Holly Bobo, a 20-year-old nursing student who was last seen in April 2011, the Tennessee Bureau of Investigations said Monday night.

Bobo's brother told authorities in 2011 he saw a man in camouflage leading her away from their home in the small town of Darden in Decatur County.

It was in Decatur County that the remains were discovered Sunday.

Two men have been indicted in her murder.

Jason Wayne Autry, who is already in prison for an unrelated assault conviction, was indicted on especially aggravated kidnapping and first-degree murder charges by a special grand jury.

Autry, 39, was a longtime friend of Zachary Adams, 29, who was indicted earlier on the same kidnapping and murder charges.
