Adam Mayes and his wife Teresa Mayes were each charged with two counts of first-degree murder and two counts of especially aggravated kidnapping in a Hardeman County, Tenn., affidavit Wednesday morning. Teresa Mayes is in custody in the Hardeman County Jail.
Charges came after Gary Bain, on April 27, notified the Hardeman County Sheriff's Department his wife, Jo Ann Bain, and three daughters, Adrienne Bain, 14, Alexandria Bain, 12, and Kyliyah Bain, 8, were missing.
Law enforcement officials found the bodies of Jo Ann Bain and her oldest daughter, Adrienne, buried behind the home Adam Mayes rented with his wife and parents on Highway 9 in the Alpine community near Guntown.
Teresa Mayes admitted in the affidavit to helping take the two youngest daughters and being present when Adam Mayes killed Jo Ann and Adrienne Bain. The affidavit says their deaths took place in the garage of their Newcastle Road home in Hardeman County on April 27.
Teresa Mayes also said the killings were a part of an effort to kidnap Alexandria and Kyliyah Bain.
In an interview with the Associated Press, Adam Mayes' mother-in-law admitted she thought Mayes may be the father of Alexandria and Kyliyah Bain.
Aaron T. Ford, special agent in charge of the FBI Memphis field office, said they are still searching in the rural area around Guntown for Mayes and are operating under the assumption he has the two youngest girls with him.
Authorities would not comment on the motive of the killings and abductions.
Union County Sheriff Jim Edwards said his office is still working hard and answering calls and checking on tips from the community, in addition to their efforts to find Mayes.
"We're working the investigative side and the fugitive side to make sure this county is protected and safe," Edwards said. "We're still making arrests. Made a drug arrest yesterday and working a sexual battery case and life goes on, and everyday business goes on as well as this added effort with the FBI and the Marshal's service. My deputies are having to step up - investigators, the chief deputy, myself. We're all operating on sometimes three to four hours of sleep or less. We're proud to do it."
During an FBI press conference Wednesday, Ford addressed Alexandria and Kyliyah Bain directly.
"To the girls, first know we are spending day and night, 24 hours a day, trying to get you back home to Tennessee. We will use every federal state and local resource," he said.
Ford then addressed Mayes: "To Adam Mayes, number one, turn those girls in to a safe location: police, a church with responsible adults or a hospital, and then peacefully and safely turn yourself in."
Ford said Mayes has connections to many other states including Texas, Florida, South Carolina, North Carolina and Tennessee where the Bains were kidnapped.
According to people living near the Alpine community home, two additional area men have been taken into police custody. FBI officials didn't return calls to confirm or deny the claim.
Adam Mayes' mother, Mary Mayes, also was charged Monday with three counts of conspiracy to commit especially aggravated kidnapping and is in the Hardeman County Jail.

Special Agent in Charge for the FBI’s Memphis field office said the addition of Mayes to the Top 10 Most Wanted list means the reward for information leading to an arrest is now $100,000. Other agencies have pitched in to bring the total reward to $175,000.
