ST. LOUIS, Mo. – Authorities are telling travelers there is one simple and easy thing they can do in their hotel rooms to help stop sex trafficking.

KTVI is reporting a group called “Exchange Initiative” said it believes just snapping a picture can help expose the “offices” of pimps across the U.S.A.

Experts said almost every online sale of a human body shows a picture taken in a hotel room.

Sometimes you can even see landmarks in the background, KTVI reported.

The group is now working to compile hotel room pictures on a website that could help police find traffickers.
