OKLAHOMA CITY (AP) — A woman was arrested after her 14-year-son told authorities he escaped from a home where he'd been kept for 4 1/2 years, spending most of his time locked in a bedroom closet, police said today.

A security guard at a National Guard facility in Oklahoma City called police on Friday after the teen showed up malnourished and with numerous scars and other signs of abuse, police Sgt. Gary Knight said.

"He was hungry. He was dirty. He had numerous scars on his body," Knight said. "It was very sad."

The boy was taken to a hospital to be examined and then turned over to the custody of the Department of Human Services, Knight said.

After police interviews, officers on Saturday arrested the boy's mother, 37-year-old LaRhonda Marie McCall, and a friend, 38-year-old Steve Vern Hamilton, on 20 complaints each of child abuse and child neglect. Formal charges have not been filed, and both were being held on $400,000 bail, according to jail records.

The teen, wearing only a pair of oversized shorts held up by a belt, walked up to a security guard at the Guard facility around 5 p.m. Friday and asked where a police station was located so he could report being abused, according to a police report.
