Sorry, Dorothy. Kansas, too.

Wichita police are concerned about an increase in human trafficking. … Police say they are concerned about the growing trend of sex trafficking in the city and are looking for real answers. Over the past five years, police have documented numerous cases. In 2006, there were 11 cases, 10 in 2007 and nine in 2008. However, starting in 2009, the number grew to 17 cases, followed by 22 cases in 2010. So far this year, there have been 28 sex trafficking cases. Most of the documented cases are local and don't involve transporting the victims. Police say the cases are difficult to investigate because there is sometimes a lack of evidence. There's also a lack of data regarding the crime. What make them most difficult to investigate, though, are the uncooperative victims. … Police say they are doing a lot to slow down the problem. They point to the work the Exploited and Missing Child Unit has done. Several investigators have recently gone to conferences that deal with human sex trafficking.
