An Indiana woman claims she witnessed her children be possessed by demons.

Latoya Ammons, a mother of three from Gary, shared her story with the Indy Star, a tale filled with children walking on walls, big black flies, haunted houses and exorcisms.

Ammons' story was even supported by local officials and medical staff- who say they saw Ammons' 9-year-old son walk backwards on the ceiling, the Indy Star reported Monday.

"I am a believer," Gary Police Captain Charles Austin told the Indy Star.

The haunting began when Ammons and her family moved into a house in November 2011. Two months later the family noticed strange things, such as swarms of black flies surrounding the house's porch and the shadow-like outline of a man walking in the living room, the Indy Star reported.

Ammons said one night she saw her 12-year-old daughter hovering unconscious above her bed at 2 a.m.

"I thought, 'What's going on?' " Rosa Campbell, Ammons' mother, told the Indy Star. " 'Why is this happening?' "

Ammons told the Indy Star she contacted two clairvoyants, who told her the home was possessed by more than 200 demons. The clairvoyants advised Ammons to move, but the family did not have the money, the Indy Star reported.

The family tried burning sage to purge the house, but a few days later the whole family was possessed, Ammons told the Indy Star. Ammons' 9-year-old son and 7-year-old son were taken to the hospital to have their behavior examined. By that time the Department of Child Services was investigating Ammons on suspicion of child abuse.

One nurse, Willie Lee Walker, told the Indy Star the 9-year-old had a "weird grin." The boy then crawled up the ceiling and jumped over his grandmother

"He walked up the wall, flipped over her and stood there," Walker said. "There's no way he could've done that."

When police arrived later they asked if the boy was simply performing acrobatics.

Valerie Washington, a caseworker from DCS, said the police were wrong.

The boy "glided backward on the floor, wall and ceiling," Washington said, according to the Indy Star.

After the hospital incident Ammons' children were removed by DCS.  A reverend, Michael Maginot, was requested to perform an exorcism. After several exorcisms, the last of which was performed in Latin instead of English, the possessions subsided, the Indy Star reported.

Ammons' children were eventually returned to her in November 2012, six months after they were taken away. Ammons told the Indy Star that God, not doctors, saved her family

"When you hear something like this," Ammons said, "don't assume it's not real because I've lived it. I know it's real."
