Country singer Whitney Duncan is asking for prayers as new search warrants are being executed in the disappearance of her cousin, Holly Bobo.

Bobo was abducted on April 13, 2011. The 20-year-old nursing student was last seen by her brother, Clint, walking into the woods behind their home in Darden, Tenn. with a man dressed in camouflage. Clint believed the man was her boyfriend and that they were breaking up, so he did not pursue them, not realizing it was a kidnapping until it was too late. He later fell under suspicion, but a team of investigators his family engaged checked his story out and cleared him.

Last year, Bobo's family brought in a new team led by Sheila Wysocki, who made national headlines by solving the cold case murder of her college friend. She now heads a non-profit organization called Without Warning, which threw its full resources into the Bobo case and developed some new theories that the crime must have been committed by someone local.

In a startling new turn of events, the Tennessee Bureau of Investigations has announced it executed search warrants at various locations Friday (Feb. 28) in connection with its ongoing investigation.

"To say we have a suspect in this case would be premature," the TBI said in a statement. "We have been working leads on this case which led to the search warrant executions."

The TBI did not release information about where those search warrants were executed, but the Shelby County Sheriff's Office has confirmed to WMCTV's Action News 5 in Memphis that it has a cadaver dog in Parsons to assist with the searches.

WMCTV reports a heavy law enforcement presence on Adams Lane in Holladay, roughly 15 miles north of Parsons.

Duncan -- who rose to fame from appearances on ‘Nashville Star’ and ‘Survivor' -- took to social media to ask for prayers about the latest development.

There is an $85,000 reward for information leading to Bobo’s return. Anyone who might have information concerning Holly Bobo’s disappearance is urged to call the TBI at 1-800-TBI-FIND, or email

UPDATE: TBI Director Mark Gwyn addressed the media Friday afternoon (Feb. 28) at the property on Adams Lane where investigators had been searching. He said the searches will continue Saturday and possibly Sunday, both there and at other locations. He did not reveal the other locations, nor did he say what information investigators might have that led them to execute the search warrants.

According to WBIR, the property on Adams Lane is owned by 29-year-old Zachary Adams. Decatur County Sheriff Roy Wyatt tells WBIR that Adams was booked into the Decatur County Jail Friday on a charge of aggravated assault, but could not comment on whether that charge was in any way related to the Holly Bobo case.

Adams' grandfather, Dick Adams, declined to comment. Danielle Darnell -- a friend of Zach Adams' -- tells WBIR that she and other members of her family met with the TBI Friday to answer questions about Adams. She did not reveal the line of questioning.

The Jackson Sun reports that Adams was also arrested in Benton County on Wednesday (Feb. 26) on charges of possession of drugs and drug paraphernalia. He was released on $10,000 bond.

The TBI has not named any suspects in the Holly Bobo case.
