"Three cases were identified as being possible sex trafficking cases, and one homeless teen was transported back to the command post after it was discovered that he had not had anything to eat in three days. He was then debriefed and turned over to Child Protective Services for aftercare," the U.S. Marshals Service said in its release.

The U.S. Marshals Service did not say where the children were located, WJBK reported.

"The message to the missing children and their families that we wish to convey is that we will never stop looking for you," the U.S. Marshals Service said in its news release.
