Cobb Police Sgt. Dana Pierce said the children's injuries were discovered Monday afternoon when their mother, Shannon Nicole McDowell, 26, drove to WellStar Cobb Hospital with their 2-year-old son, who had substantial external and internal injuries, including brain trauma.
The boy was flown to Children's Healthcare of Atlanta, where he remains in a non-life-threatening condition. Detectives interviewed McDowell at the children's hospital, then took her to the Crimes Against Children office on Whitlock Avenue in Marietta for further questioning. During the investigation, they learned that McDowell had a 4-year-old daughter who was left alone at the family's Lanier Drive residence in south Cobb, Pierce said.
Detectives found the daughter, "who was also suffering from current injuries as well as injuries she sustained in the past," and took her to WellStar Cobb Hospital. She is now in the custody of the Department of Family and Children Services.
McDowell was arrested Monday night on charges of cruelty to children, contributing to the deprivation of a minor and making false statements. She is being held at the Cobb County Jail on a $50,000 bond.
Damon Earl Jennings, 29, of Marietta, turned himself in to Cobb Police late Monday after he was charged with first- and second-degree cruelty to children. He was arrested in Cobb two years ago on misdemeanor charges of driving with a suspended license and no proof of insurance.
