MARIETTA, Ga. (AP) — A metro Atlanta couple is being held in the Cobb County jail after their special needs son was hospitalized with a brain injury.

Authorities say the child's father, 39-year-old Kenneth Thompson, is being held without bond on charges of battery and cruelty to children. The child's mother, 32-year-old Monica Knouff, is being held on $75,000 bond on charges of child deprivation and cruelty to children.

The Marietta Daily Journal (http://bit.ly/10SYyOJ ) reports Thompson is accused of causing a brain injury that required the boy to be airlifted to Children's Healthcare of Atlanta. Officials say the boy's mother is accused of failing to seek timely medical treatment for her son's injuries.

Knouff's attorney says her client is not guilty and expects her to be exonerated. It's unclear if Thompson has a lawyer.
