A Tennessee man was charged Wednesday with murder and aggravated kidnapping in the death of a nursing student who was last seen outside her home nearly three years ago. Holly Bobo was 20 when she disappeared on April 13, 2011. Her brother told authorities he saw a man in hunting clothes leading her into the woods around the family home near Parsons, about 100 miles northeast of Memphis. Bobo's brother said he initially thought she was being taken into the woods by her boyfriend, but grew concerned when he saw the man's arm holding onto his sister. He called his mother, who then contacted 911, according to local reports. Bobo had been preparing to go to class at nursing school on the morning of her disappearance, Reuters reported. A small amount of blood was found in the family's carport, where Bobo was believed taken from while on her way to school, police sources told FoxNews.com at the time of her disappearance. Last week, investigators in the case searched the home of 29-year-old Zachary Adams and he was arrested in an unrelated aggravated assault case on Friday. Tennessee Bureau of Investigation director Mark Gwyn on Wednesday announced the grand jury indictment against Adams in Bobo's disappearance. Gwyn would not say what kind of evidence was found during the search or whether authorities have recovered any remains. Adams' home in the Holladay community is about 15 miles from Bobo's home where she was last seen.
