The next year, the boy, then 15, admitted to sexually abusing another adopted child and was placed in a behavioral treatment center.

Later, he admitted to “numerous incidents” of sexual abuse of siblings and foster children, the lawsuit states.

When he was released from the treatment center, DSS staff told the Longs that they were required to accept him back into their care and that he would only be offered additional services if he abused a child again, Long said.

The Longs reported the boy’s behavior to law enforcement and, after an investigation, he was charged in Juvenile and Domestic Relations District Court with four counts of aggravated sexual battery of a child less than 13 years old, according to the lawsuit.

The boy pleaded guilty to each of the charges and is currently serving an indefinite term of confinement with the Department of Juvenile Justice, the lawsuit states. His attorney did not immediately respond to a request for comment.

The lawsuit also alleges that the investigator assigned to the case spoke with the mother of one of the boy’s alleged victims, who said that she had reported the sexual abuse to two DSS employees in 2011.
