The Winston-Salem Troublemaker has a story about human trafficking in North Carolina, and how the FBI is looking for help in combating it.  He also highlights some cases tied to the Piedmont:

Does human trafficking exist in the Triad?

In May of 2004,
Greensboro Police uncovered the State’s largest Human Trafficking case
when a Home Depot Security Guard reported a large number of vehicles
and scantily dressed young Hispanic girls being delivered to a van.
Over 20 people were held by authorities. Prostitution trafficking
charges followed.

Greensboro Police have investigated several
Hispanic brothels within the last few years. Gurrant Street, Phillips
Avenue, Rainbow Street and Freeman Mill Road have hosted Hispanic
brothels.

A Greensboro strip club catering to Hispanics is  currently suspected for having human trafficking connections.

In
Winston Salem, local authorities shut down a Hispanicic brothel on
Country Club earlier this year. Several people were charged and
deported.

I guess we can’t say this kind of thing only happens in other places.
