Couple, Benjamin and Hope Jordan, have said their dog helped them discover the family babysitter was secretly abusing their baby when they were not at home.
The parents say they became suspicious about the babysitter after their pet started becoming aggressive towards her.
The child’s father reports:
"About five months into her being our babysitter, we started to notice that our dog was very protective of our son when she would come in the door.”
"He was very aggressive towards her and a few times we actually had to physically restrain our dog from going towards her.”
After noticing the dog's behaviour towards Khan, the couple put a mobile phone under the sofa to record for several hours what was happening when they their left seven-month-old Finn in her care.
“It started with cussing. Then you hear slap noises and his crying changes from a distress cry to a pain cry.”
“I just wanted to reach through the audio tape, go back in time and just grab him up.”
“To know that for five months I had handed my child to a monster, not knowing what was going on in my house for that day.”
Charleston City Police arrested Khan, who had initially passed a criminal background check conducted by the Jordans, a few weeks later and she confessed to the abuse.
State authorities will also reportedly place Khan on a child abuse registry, meaning she can no longer work with children.
Mr Jordan told Fox News: “He is a very personable dog so for him to show aggression toward anyone is a sign that something was wrong because he never shows aggression.”
“Just the simple mannerisms of him raising his hair up, getting excited, getting worried about our son, was definitely enough to make us understand that he was trying to tell us something about this babysitter.”
Mrs Jordan described what she heard in the recording as “a nightmare.”
She said: "For seven and a half hours my son cried nearly the entire time. She was cursing at him, calling him horrible names and it came for no reason.”
"He wasn't acting up." He hadn't been crying until she left him alone in his crib for hours and of course the physical abuse.”
