Few studies have examined Internet sex trafficking through the lens of law enforcement working these cases. The purpose of this research is to explore the dynamic nature of policing sex trafficking in the online environment. The qualitative data was drawn from interviews with police investigators and detectives who work sex trafficking cases in two urban cities in Texas. The results suggest that the nature of sex trafficking has significantly evolved since the advent of social media, including the strategies for recruitment of workers and clients, making enforcement easier with some aspects and much more difficult with others. Additionally, law enforcement interviewed believe domestic sex trafficking is a much greater issue in their metropolitan area than international sex trafficking.
