Investigators, who are searching for the missing Bain family who disappeared 10 days ago after leaving their Tennessee home, said the four missing family members are in danger and issued warrants for a suspect in the kidnapping.

Police from Tennessee have teamed up with the FBI as they search for Jo Ann Bain, 31, of Hardeman County in western Tennessee, and her daughters, Kyliyah Bain, 8, Alexandria Bain, 12, and Adrienne Bain, 14. Authorities believe that Adam Mayes, 35, may have kidnapped the four members of the Bain family.

On Sunday, authorities discovered two bodies at the Mississippi home of Mayes. Officials, however, could not confirm if the bodies they discovered in Mayes' apartment belonged to either Jo Ann or any of her daughters, reported Reuters.

The FBI said they were waiting on a reported the Tennessee's medical examiner before identifying the bodies. A spokesman for the FBI did not disclose if any of the bodies were children, reported the Associated Press.

We're waiting on the results, said FBI spokesman Special Agent Joel Siskovic.

As police attempt to track down Mayes and the Bain family, they warned that he might have changed his appearance to evade capture.

We do have information that he has altered the appearances of everybody including himself, primarily from cutting their hair, Siskovic said, reported ABC. The girls may have far shorter hair than the pictures out there.

In the meantime, arrest warrants for kidnapping charges have been issued for Mayes.

The Bain family has been missing since April 27. Gary Bain, Jo Ann's husband and the father of the missing girls, had attempted to get in touch with his wife throughout the day and was unable to reach her. When the girls did not return from school, he reported them missing to the local sheriff's office. The family car was also gone.

Helm said that Bain's adult daughter and his granddaughter had spent the night at the family home, but they did not see any sign of the family the next morning. They assumed the four just left the house before anyone woke up.

Mayes is a family friend who was staying there that night to help the family pack and drive a U-Haul to Arizona the next day with Gary because the family was planning on moving there within the month, Kristin Helm said, a spokeswoman for the Tennessee Bureau of Investigation, reported the AP. Gary was asleep at the home that night and woke to find them gone in the morning and the car gone. Mayes was gone too.

Police spoke with him early in the investigation at his home in Mississippi. They discovered him there after he left the Bain family home on April 27, but they did not see the missing family members there at the time. However, when they tried to find him again because he gave them misleading information, Mayes had fled and the two bodies were found.

Early days of the investigation led us to suspect Adam Mayes, Siskovic said, reported ABC.

We don't know exactly where he's going. We do consider him armed and dangerous.

On Sunday, forensic scientists with the Tennessee Bureau of Investigation searched the garage and the backyard at the Hardeman County, Tenn., home where the Bain family resided. However, there did not appear to be any new evidence.

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., according to the AP.

Kirkland said the family often frequented the restaurant where she works and did not notice anything wrong with them.

She seemed so happy, Kirkland said.

On April 30, police discovered the vehicle. Mayes was last seen on Tuesday in Guntown, Miss., about 80 miles from the Bain's Tennessee residence, reported the AP.

The FBI and the U.S. Marshals are offering a reward of $50,000 for any information leading to the whearabouts of Bain and her daughters and the arrest of their possible abductor, Mayes.

We are very concerned about the girls' safety and believe someone in Tennessee or Mississippi may have information about what happened to them, Tennessee Bureau of Investigation spokeswoman Kristin Helm said on Sunday.

If anyone has seen or has had contact with Adam Mayes in the last week, we would urge them to come forward, she said.
