The two young girls were on their stomachs. From where they lay, they could see Adam Mayes, the man who took them from their home in Tennessee two weeks earlier and who now had them hiding in the Mississippi woods.

State officers approached.

Mayes was charged with the killings of the girls' mother and older sister. The end of a days-long manhunt seemed within reach. The motive for the kidnappings might be explained.

But as the officers drew nearer, Mayes pulled out a gun and shot himself in the head. The girls watched.

New details revealed Friday by the FBI recounted the rescue of Alexandria Bain, 12, and Kyliyah Bain, 8.

When investigators came upon Mayes, "the girls were on their stomach face-down. They were close enough to see what was going on when he killed himself," FBI spokesman Jason Pack said.

Afterward, the girls were tended to by two female agents, who rode with them in an ambulance to a hospital.

"They were scared and relieved," Pack said. "They were hungry and thirsty. They gave them water, and we drove them out right away."

A tip to the FBI led officers to the area. The FBI on Wednesday had put Mayes on its list of 10 most wanted fugitives.

The tip was not that someone had spotted Mayes, but that an old log cabin behind a church might be a good hiding place.

Agents had searched the area before, but they went again.

There is no evidence that Mayes and the girls used the cabin, but they were believed to have been in the area for a few days, Pack said.

"There was no shelter or anything. It looks like they were in the open woods," he said. "They were dehydrated and dirty, like they were here for several days."

Mayes, 35, was accused of abducting Alexandria and Kyliyah from their Whiteville, Tennessee, home, in late April, and killing Jo Ann Bain and her eldest daughter, Adrienne, 14.

Officers with the Mississippi Highway Safety Patrol and state Department of Fisheries, Wildlife and Parks rescued Alexandria and Kyliyah, the FBI said.

Meanwhile, three additional arrests were made in connection with the case, a law enforcement source told CNN. One person was arrested for making a false statement and two others for illegal possession of a firearm, the source said.

The identities of the individuals were not immediately known, but it included the person who provided Mayes with the gun he used to shoot himself, the source said.

Alexandria and Kyliyah were released overnight from Le Bonheur Children's Hospital in Memphis, Tennessee, hospital spokeswoman Sara Burnett said.

"They were released in the middle of the night, somewhere between 2 and 5 a.m.," Burnett said.

Burnett did not know to whom the children were released.
