Federal and local officials have rescued 13 previously missing children, whom authorities determined to be at risk of human trafficking, in and around Memphis.

The Tennessee Bureau of Investigation (TBI), which worked with the U.S. Marshals Service, Homeland Security Investigations, Memphis Police Department and Tennessee Department of Children’s Services on the two-day mission called "Operation Not for Sale," said officials were focused on locating children at risk of being trafficked. 

"There may be children coming from an environment where they have been sexually abused, previously, in their life. But that might be their norm," Foster Care Institute founder and director, Dr. John DeGarmo, who works with child welfare agencies across the globe, told Fox News Digital when asked what makes a child at risk of being trafficked. 

Those children may be coming from broken homes or foster care and "seek out love" elsewhere because they have not found it in their current lives. Those children can be easily "misled by predators" and "groomed" under false hopes and promises of better lives, DeGarmo said.

Police might identify these kinds of children based on their own records of families with histories of domestic violence or sexual abuse. They might identify children who have unique tattoos or bands, or even new and expensive clothing, according to DeGarmo.

In 2021, the National Center for Missing and Exploited Children (NCMEC) received more than 17,200 reports of child sex trafficking from all 50 states, as well as Washington, D.C., and Puerto Rico.

"It's America's ugly secret," DeGarmo said.

Weeks prior to Operation Not for Sale, intelligence analysts identified children who were at "high risk in regard to human trafficking," TBI said in a press release. Then, between Nov. 2 and 3, six search teams went to 56 different locations in their efforts to locate the missing children they had identified as high-risk.
