KNOXVILLE (WATE) -- Suzanne Douglas, 29, and her boyfriend, Adam Hayes, 20, were arrested Christmas Day on aggravated child abuse and neglect charges.
The couple lives together in Jellico with her two children, a one year old and a two year old.
Suzanne's mother, Linda Douglas, says she believes both kids were being abused.
"If I have to kidnap and go to jail, I would to keep those children away," Linda Douglas said.
The grandmother reported the alleged abuse to police after a family dinner on Christmas Eve. She says she noticed switch marks on the two year old girl.
She also discovered severe bruising and what doctors diagnosed as a dislocated elbow.
"Her buttocks was black from bruising, I mean black. Not yellow or brown, but black," said Douglas.
According to Douglas, this is not the first incident. Over Thanksgiving, she claims, the two year old was burned with a cigarette lighter.
Douglas says she reported that incident to the Tennessee Department of Children's Services, but claims the agency did little investigating.
"This would not have happened if they had taken any kind of action. If they had even started a parenting plan or that we are going to monitor you, we are going to come in here and check this house. We are going to look at these children," said Douglas.
According to the Department of Children's Services, investigators are working with local police on the case, but they will not comment on the specifics of the investigation.
DCS says they are aware of the situation and have made sure the children are safe.
Douglas blames the physical abuse on her daughter's boyfriend, Adam Hayes, but says both he and her daughter need help.
"When he came into the picture things were not like this. The children were bathed, the children were clean, they were up and doing things. I blame her for allowing it, yes," said Douglas.
Suzanne Douglas and Adam Hayes remain in police custody. According to Linda Douglas, the two children are now with their biological fathers.
