Sexual predators exist in our society and their evil desire leads them to commit heinous, brutal crimes with little concern for their victims or the toll it takes on the community. Violent sociopaths have no interest in the needs or safety of anyone else and see ordinary people as either targets or competitors. They have no hesitation taking what they want from their victims. Whether they are rapists, pedophiles, or murderers, these monsters will do whatever it takes to get their needs met and their evil desires satisfied. Captain Dean T. Olson (retired) is a veteran sex crimes detective with the Douglas County (Nebraska) Sheriff's Office, serving the Omaha area. In his 30-year law enforcement career he has seen some of the most horrible crimes committed by one person against another and he has arrested some of the worst sexual predators the nation has ever seen.
