Murder charges were filed Wednesday against the fugitive suspected of killing a Tennessee woman and her teenage daughter and fleeing with her two younger girls.

Two first-degree murder counts against 35-year-old Adam Mayes, who has been sought for more than a week, were announced Wednesday. His wife, Teresa Mayes, also was charged.

An affidavit filed in Bolivar, Tenn., says Teresa Mayes of Guntown, Miss., told authorities she was there April 27 when Adam Mayes, killed Jo Ann Bain and her 14-year-old daughter, Adrienne, in a garage at their Whiteville, Tenn., home.

Teresa Mayes told officials the motive was to kidnap Bain's two younger daughters, 12-year-old Alexandria and 8-year-old Kyliyah.

A call seeking comment from Teresa Mayes' attorney wasn't immediately returned.

The wife was charged a day earlier with especially aggravated kidnapping. She said she drove her husband, the girls and the two bodies from southwest Tennessee to Guntown and saw him dig a hole in the yard.

The bodies of Jo Ann and Alexandria Bain were found buried at that property a week later.

An intense manhunt continues for Adam Mayes and the two girls.
