Raeford, N.C. — A woman whose 4-month-old son was found last week inside a suspected methamphetamine lab east of Raeford was charged Monday with felony child abuse, authorities said.

Ashley Milligan, 23, of Summerville, S.C., also was charged with obstruction of justice and manufacturing methamphetamine. She was being held in the Hoke County jail under a $125,000 bond.

The baby suffered second- and third-degree chemical burns on his chest and under his arms, Hoke County Sheriff Hubert Peterkin said. He is recovering at Cape Fear Valley Medical Center in Fayetteville.

Six people, including the child's grandmother, Michelle Lynn Tiller, were arrested Thursday when deputies broke up the drug lab in a mobile home at 165 Water Splash Road, off U.S. Highway 401.

A woman claiming to be the baby's mother called WRAL News on Sunday to say that she was returning to North Carolina from South Carolina to check on the child and talk with authorities. She said she left the boy, named Aiden, with her fiance's mother while she was working in South Carolina and said she had no idea the woman was involved with drugs.

Peterkin said Milligan was aware of the methamphetamine lab.

The baby has been placed in the custody of the Department of Social Services.

The child's father is in jail in Summerville, S.C., the sheriff said.
