GUNTOWN, Miss. - Murder charges have been filed 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 with murder and kidnapping.
An affidavit filed in Bolivar, Tennessee, said Teresa Mayes of Guntown, Mississippi, 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, Tennessee, 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.
Bain and her oldest daughter were found dead last Friday at the home where Mayes lived in Guntown, Mississippi.
Adam Mayes' mother, Mary Hayes, was also charged Tuesday with four counts of Conspiracy to commit especially aggravated kidnapping.
Earlier Wednesday, Governor Bill Haslam issued a $15,000 reward for information leading to an arrest.
Haslam's reward is in addition to $50,000 offered by the FBI and U.S. Marshals Service and $6,000 from the Tennessee Bureau of Investigation.
On Tuesday, authorities canvassed roads and searched tree lines near the home where 35-year-old Adam Mayes lived in Union County, Mississippi. Authorities have been tight-lipped about the details of the search, hoping to avoid releasing information that puts the girls' lives in jeopardy.
Authorities released a surveillance video that showed Adam Mayes at a convenience store in Union County, Mississippi, about three days after the alleged kidnapping. In the video, Mayes appeared calm when he approached the counter and had a fresh haircut.
Authorities have said Mayes was a family friend who was staying with the Bains on April 27, the day the mother and children disappeared. Before he fled, he admitted to authorities that he was the last person to see Jo Ann Bain and her daughters before the disappearance, according to an affidavit filed with the court.
The affidavit provides the first clue that the victims may have been killed soon after they were abducted. It said his wife and mother saw him digging a hole in the yard on April 27 or soon after.
Hundreds of adults, teens and children came from throughout west and central Tennessee and north Mississippi for a prayer vigil Tuesday evening at Bolivar Dixie Youth Park, where the two oldest Bain girls played softball.
Mourners sang songs and bowed their heads in prayer as they held red, yellow, orange and purple balloons during the ceremony. Some wept during the vigil and sniffles punctuated the quiet night during a moment of silence for Jo Ann Bain and her three daughters.
Many of the mourners said the kidnappings have shaken their small-town, tight-knit communities, from Corinth, Miss., to Whiteville, Tenn.
Stephanie Bodiford, of Middleton, Tenn., said her son was in the same class at Central High School in Bolivar as Adrienne Bain, who along with her mother was found dead in a home where suspect Adam Mayes lived in Guntown, Miss.
Bodiford said her children have been distraught in the days since the disappearance of Bain and her daughters.
"We live in such a sheltered community," Bodiford said. "They just don't understand. They don't understand bad."
Megan Ervin said she played with Adrienne Bain on the same softball team last year. She described Adrienne as a good player who enjoyed softball.
"She was real nice but she was real shy," Ervin said.
Ervin, 16, said she and her friends have been shaken by the kidnapping and deaths.
She also said Mayes spent time at the park. He would often come see the Bain girls play, she said. Megan Ervin's mother Pam said she also saw Mayes hanging out at the park.
"It's just shocking. It could have been any of us, really, because he was always here and everybody saw him," Megan said. "He was around all these kids all the time."
Both Gary Bain and Mayes were once married to sisters, Tennessee Bureau of Investigation spokeswoman Kristin Helm said.
Jo Ann Bain's Facebook page showed in the days before the four disappeared she was packing and working on homework. Her last post, dated April 26, said "a good venting always makes you feel better." It didn't say why she was venting.
Authorities talked to Mayes early on in the investigation, but he fled when they tried to contact him again, Siskovic said.
Mayes was last seen May 1 in Guntown, about 80 miles south of the Bain family's home in Whiteville, Tennessee. He is considered armed and dangerous.
Mayes also has ties to Arizona, Texas, North Carolina, South Carolina and Florida. He may be using the aliases of Christopher Zachery Wylde or Paco Rodrigass, the FBI said.
