JACKSON, Miss. — Two unidentified bodies have been found at a Mississippi residence associated with a man suspected of abducting a Tennessee woman and her three young daughters, who are believed to be in "extreme danger," authorities said Saturday.
FBI spokesman Joel Siskovic said the bodies were found late Friday night or early Saturday morning in a residence associated with Adam Mayes, 35.
Mayes is charged in Tennessee with abducting Jo Ann Bain and her daughters. He has been described by authorities as "armed and extremely dangerous."
Siskovic said authorities on the scene were not able to positively identify the bodies. He would not say if the bodies were children.
The missing girls are 8-year-old Kyliyah Bain, 12-year-old Alexandria and 14-year-old Adrienne. They were last seen April 27 in Hardeman County, Tenn., which is about 70 miles east of Memphis. The woman's husband reported her missing and her vehicle was found abandoned.
Authorities were still trying to determine if Jo Ann Bain went with Mayes willingly. He was last seen Tuesday in Guntown, Miss., about 80 miles southeast of Hardeman County, Tenn. He'd been described as a family friend.
The FBI and U.S. Marshals Service announced Saturday a reward of up to $50,000 for information that leads to the location of the missing victims and the arrest of Mayes.
Siskovic said the bodies were found in a residence, but it wasn't clear if it was a house, mobile home or apartment. He also wasn't sure if the residence belonged to Mayes or an acquaintance. Siskovic said the bodies were found in Guntown, north of Tupelo. Lee County coroner Carolyn Green said the bodies were found outside Guntown in Union County.
Siskovic said authorities talked to Mayes early on in the investigation, but he fled when they tried to contact him again. The FBI says they were not immediately aware of Mayes having a criminal record.
Authorities had said that Mayes could be in Mississippi but that he has ties to Arizona, Texas, North Carolina, South Carolina and Florida.
"Information has been developed during the investigation that the children may be in extreme danger. Warrants for kidnapping are being issued for Adam Mayes, who is considered armed and extremely dangerous," Mississippi Department of Public Safety spokesman Warren Strain said in a news release Saturday.
The Mississippi Highway Patrol issued an Amber Alert on Saturday morning, and Tennessee authorities had also issued an alert.
Authorities described Adrienne as a white girl with brown hair and eyes. She's 5 feet 4 inches tall and 129 pounds. Alexandria has brown hair and hazel eyes and is 5 feet tall and 105 pounds. Kyliyah has blonde 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.
However, authorities said Mayes may have cut his hair, as well as cut and dyed the girls' hair to disguise their identities.
Anyone with information is asked to call 601-987-1353 or 1-800-TBI-FIND.
