Police Search Widens for Missing Memphis Mom and Daughters

—May 3, 2012 -- Police are searching for a man they are calling a person of interest in the disappearance of a Tennessee mother and her three daughters.

The Hardeman County Sheriff's Department said Jo Ann Bain and daughters Adrienne, 14; Alexandria, 12; and Kyliyah, 8; had been missing since last Friday. They were last seen leaving their home in Whiteville, located between Jackson and Memphis, Friday morning.

Bain's Dodge Durango was found abandoned on a county road less than three miles from their home on Sunday.

Officers told Memphis' ABC24 News that they'd brought in Bain family friend Adam Christopher Mayes, 35, of Guntown, Miss., for questioning on Sunday. On Tuesday, investigators issued a warrant for Mayes, charging him with filing a false report based on statements he'd made to investigators about the Bain family.

But Mayes has since disappeared, said investigators.

"We believe he has information on the whereabouts of this family," Hardeman County Sheriff John Doolan said at a news conference Wednesday.

Doolan said the family was days away from moving to Arizona before Bain and her children vanished. He said Bain had not used her cell phone or credit cards since Friday.

"As far as we know, there is no sign of foul play. We are not ruling anything out though. There is nothing saying you can't move to Mexico and change your name. There's nothing," he said.

Police continue to search Arizona, Tennessee and Mayes' town of Guntown, Miss. Doolan said Bain's husband and law enforcement hoped for a phone call soon.

"Right now, I got a concerned father. I don't care if it is a phone call, if she would just call and tell us I'm OK, I'll get a law enforcement officer to lay eyes on her and it will be over with."

Attempts by ABC News to reach Bain's husband have not been successful.
