GUNTOWN, Miss. -- A Mississippi man charged with kidnapping a Tennessee mother and her three daughters and killing two of them was added Wednesday to the FBI's 10 Most Wanted list.
The announcement came amid an intense manhunt in northeast Mississippi for 35-year-old Adam Mayes and two girls he is accused of abducting.
The girls are 12-year-old Alexandria Bain and 8-year-old Kyliyah Bain.
Federal authorities pleaded for the public's help in finding the sisters.
An affidavit filed in court Wednesday said Mayes killed their mother, Jo Ann Bain, and teenage sister, Adrienne, at the family home April 27 so he could take the two younger girls.
The bodies of the two killed were found a week later buried at the home outside Guntown where Mayes lived.
Murder charges were filed Wednesday against Mayes and his wife.
An affidavit filed in Bolivar, Tenn., says Teresa Mayes of Guntown, Miss., told authorities she was there when her husband killed Jo Ann and Adrienne Bain 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.
An intense manhunt continues for Adam Mayes and the two girls. The search has been most intense around Guntown, about 90 miles southeast of Memphis where Mayes lived with his wife and parents.
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.
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.
Many of the mourners said the kidnappings have shaken their small-town, tight-knit communities, from Corinth, Miss., to Whiteville, Tenn.
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."
When asked if she had ever spoken with Mayes, she recoiled, saying, "No."
"When I first saw him, I kind of had a bad vibe about him, so I just kind of stayed away," Ervin said. "But then I saw him here all the time and I figured he's no threat to us because he's always here. Obviously, that wasn't true."
