The missing children were considered to be "some of the most at-risk and challenging recovery cases" and some were likely victims of child sex trafficking, child exploitation, abuse and had medical or mental health conditions, officials said.
As part of the operation, investigators cleared 26 arrest warrants and filed additional charges for alleged crimes related to sex trafficking, parental kidnapping, registered sex offender violations, drugs and weapons possession, and custodial interference.
The operation also included other children located at the request of law enforcement to ensure their well being. Investigators say they were able to confirm each child's location in person and assure their safety and welfare.
According to the The U.S. Marshals Service, of the 26 warrants, 19 were arrest warrants, and a total of nine people were arrested. Officials noted some of the individuals arrested had multiple warrants.
Authorities did not identify the suspects.
