The man suspected of killing a mother and her oldest daughter in order to kidnap two other young girls has been rushed to the top of the FBI's list of its Top Ten Most Wanted fugitives. 
 
 Adam Mayes is believed to be armed and on the run from authorities with two of the girls he allegedly kidnapped on April 27. 
 
 "We will hunt down Adam Mayes and rescue those two little girls," said FBI Special Agent Aaron Ford at a press conference today. 
 
 Mayes, 35, and his wife, Teresa, 31, are both charged with first degree murder and especially aggravated kidnapping. Adam Mayes has also been charged with unlawful flight to avoid prosecution, a federal crime which gave the FBI jurisdiction over the case. 
 
 He takes the place on the FBI's infamous wanted list of Boston mob boss James "Whitey" Bulger who was captured last year. 
 
 "We keenly and firmly believe that Adam Mayes is out there somewhere with those two young children and it's going to be up to the public to help us bring these children back home and place him in custody where he needs to be," said Sheriff Tommy Wilhite of Union County, Miss., where Mayes lives. 
 
 When asked if they had established a motive for the kidnapping, Ford said, "We have no indication now as to motive." 
 
 Adam and Teresa Mayes are charged with killing JoAnn Bain and her 14-year-old daughter, Adrienne, in the Bain's Tennessee home in order to kidnap the two younger girls, according to affidavits filed in the murder charges. Teresa Mayes told police she witnessed Adam kill JoAnn Bain in the garage of the Bain's home, and then kill Adrienne Bain in the home itself. 
 
 Adam and Teresa Mayes then took the dead bodies and two young girls to the Mayes' home in Mississippi, where Adam Mayes allegedly buried the two bodies, the documents state. 
 
 "Teresa Mayes stated that Adam Mayes intended to take Alexandria Bain and Kyliyah Bain from their home in Hardeman County," the affidavits state. "Both murders were directly part of the kidnapping of Alexandria Bain and Kyliyah Bain." 
 
 The bodies of mother and daughter were found ealier this week in the backyard of the home Mayes shares Teresa and his mother and father. 
 
 Police believe the two youngest daughters are still in Mayes' custody and may be in extreme danger. The FBI has warned that Mayes may have changed his appearance and the appearances of the two girls since they were last seen. 
 
 Police located a trailer that Mayes had rented from Union County, Miss., that contained items belonging to the two girls, the documents state. 
 
 Police arrested Teresa Mayes and Mary Mayes, Adam's mother, on Tuesday in connection with the kidnapping. 
 
 Mary Mayes is charged with conspiracy to commit especially aggravated kidnapping. Both Mary and Teresa Mayes confessed to police that Teresa helped transport the children and bodies from Mississippi and that they both witnessed Adam Mayes digging the holes in the Mayes' backyard, according to the arrest documents. 
 
 Mayes was last seen on April 30, in surveillance video from a grocery market in Guntown, Miss., where he lives. Police have also found a trailer Mayes rented from Guntown that contained personal items belonging to the two young girls. 
 
 Teresa Mayes' sister, Bobbi Booth, said her sister knew about the killings, but may have been too scared to call the police, according to the Associated Press. 
 
 Authorities are offering a $71,000 reward for information leading to Adam Mayes' whereabouts and arrest, including $6,000 from the Tennessee Bureau of Investigation, $50,000 from the FBI and U.S. Marshals Service, and $15,000 from the Tennessee Governor's office. 
 
 The Tennessee Bureau of Investigation is offering a $6,000 reward for information leading to Adam Mayes' whereabouts and arrest, and the FBI and U.S. Marshals Service are offering a $50,000 reward for information leading to the location of the missing victims and the arrest of Mayes. ||||| fbi.gov Jo Ann Bain and her daughters, Adrienne, 14, Alexandria, 12, and Kyliyah, 8, are believed to have been abducted by a family friend, Adam Mayes. Police believe the two younger girls are still with Mayes. 
 
 A Tennessee medical examiner identified two bodies Monday as those of Jo Ann Bain and her eldest daughter, Adrienne, 14, who are believed to have been abducted from their home in Whiteville, Tenn. on April 27. 
 
 Two other girls - Alexandria Bain, 12, and Kyliyah Bain, 8 - are believed to be with the man police have identified as the kidnapper, family friend Adam Mayes. 
 
 The bodies of Jo Ann and Adrienne were found Saturday behind Mayes' home near Guntown, Miss. 
 
 Earlier Monday, state troopers stopped vehicles at roadblocks and officers searched the yard of a home in northern Mississippi, as they looked for the remaining girls and Mayes, 35. 
 
 Officers also searched the yard of a home near Guntown that's been linked to Mayes. He was last seen a week ago in Guntown. 
 
 Kidnapping warrants have been issued for Mayes. The Mississippi Department of Public Safety said Saturday it believed "the children may be in extreme danger." 
 
 Mississippi Dept. Of Public Safety / AP Adam Mayes, considered "armed and extremely dangerous," is wanted in connection with the disappearance of Jo Ann Bain and her three daughters, who were abducted in Tennessee and last seen in Mississippi. 
 
 Before they disappeared, the Bains had been preparing to move to Arizona. 
 
 'A good venting' 
 
 The mother's Facebook page shows that 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. 
 
 A web of ties connects Mayes to Bain and her family. They were all known around Whiteville, a town of about 4,500 people 60 miles east of Memphis. 
 
 Mayes was a longtime friend of Bain's husband, Gary, and had been at their home the evening before they disappeared, police said. 
 
 Both Gary Bain and Mayes were once married to sisters, Tennessee Bureau of Investigation spokeswoman Kristin Helm said. 
 
 Mayes had stayed over at the Bains' house to help the family pack and load up a U-Haul to drive across the country to Arizona, Helm said. 
 
 Gary Bain, who was at the house that night, awoke to find his wife, daughters and Mayes gone. He couldn't reach his wife on her cell phone that day, and reported them missing when the girls didn't get off the school bus. 
 
 While authorities say Mayes is likely to be armed and extremely dangerous, acquaintances describe him as friendly, helpful and like an uncle to the girls. 
 
 Gerald Long, 60, of Jackson, Tenn., said he last saw Mayes about two years ago. He said Mayes lived across the street from him for about a year with his wife, Teresa. He described Mayes as a "sociable person." 
 
 He was helpful, Long said. "He didn't seem violent or anything." 
 
 As for his relationship with his wife, Long said "they were always up and down about things." Long would not elaborate. 
 
 The neighbor said he thought Mayes and his wife were no longer together. 
 
 Amber alert frustration 
 
 Jo Ann Bain's aunt Beverly Goodman, who works at Whiteville City Hall, said that her niece was not the type of woman to run off with someone. 
 
 She expressed frustration that the authorities didn't issue an Amber Alert sooner. 
 
 "What would it have hurt to put an Amber Alert out?" Goodman said. "They might have saved a couple of lives." 
 
 "Jo Ann and the kids, everyone loves them. We're just hoping to hear that they're safe," said Linda Kirkland, a family friend and cook at the Country Cafe in Whiteville, Tenn., speaking before the bodies were found. 
 
 Kirkland said the woman and her daughters were moving to Arizona because two of the girls had asthma. 
 
 FBI spokesman Joel Siskovic said authorities talked to Mayes early on in the investigation, but he fled when they tried to contact him again. 
 
 Authorities had said over the weekend that Mayes could be in Mississippi, but added that he has ties to Arizona, Texas, North Carolina, South Carolina and Florida. 
 
 Alexandria Bain has brown hair and hazel eyes and is 5 feet tall and 105 pounds, authorities said. Kyliyah has blond hair and brown eyes and is 4 feet tall and 57 pounds. 
 
 Mayes has brown hair and blue eyes and is 6 feet 3 inches tall and weighs 175 pounds. 
 
 Authorities said Mayes may have cut his hair, as well as cut and dyed the girls' hair to disguise their identities. 
 
 A reward of up to $50,000 for information leading to the apprehension of Mayes and location of the victims has been offered. Contact the Tennessee Bureau of Investigation at 1-800-824-3463.
