The Iowa Department of Public Safety wants you to stay aware if you're headed to the state fair this weekend. The department is launching a new study to determine the severity of human trafficking at the fair and other areas around the fairgrounds. The Iowa Office to Combat Human Trafficking says if you see something, report it immediately. “We aren't going to turn down tips, and if it's something you feel in your gut and something is not right, your gut is probably right. So please call a tip in,” Ray Fielder said.You can report a tip online at stophtiowa.org, or by calling the National Human Trafficking Hotline at 888-373-7888.
