It was their duty to protect the most vulnerable and authorities say they failed.
Two Wayne County social workers appeared in court this afternoon, after a young child dies on their watch.
Here's what this case is about: A mother, suspected to be mentally ill and abusive towards her child, and two social workers accused of not going far enough to protect the child before his death.
Judge Kenneth King presided over the preliminary examination of the two Wayne County social workers, charged for their alleged roles in the death of a 3-year-old Detroit boy.
Elaina Brown and Kelly Williams were held liable in the death of Aaron Minor.
It was last May investigators say when the boy's body was found in the apartment he shared with his mother, who was charged with his murder.
The social workers are accused of failing to follow up on warning signs and failing to follow protocol that could have possibly saved the child.
Testimony is to continue tomorrow in this exam.
Brown and Williams could end up with 10 to 15 years in jail if convicted.
