 Attention Capitol Hill residents. This is a community notification of a new sexually violent predator in your area. Please stay tuned to the following short program for more information. Hi I'm technician Ron Hackett with the Denver Police Department. The sex offender registration and compliance unit at DPD is responsible for the registration monitoring and tracking of all registered sex offenders and sexually violent predators who live in the city and County of Denver. Here's a brief history of sex offender legislation in Colorado. Our state laws trickle down from federal government mandates. In 1994 we had the Jacob Wetterling Act which mandated that states would establish a sex offender list. Magans law of 1996 said that the public would have access to those sex offender registration lists. The Pam Litchner Act of 1996 stated that some offenders might have to have lifetime registrations and the Adam Walsh Act of 2006 unified sex offender laws across a country. In Colorado the legislature has determined that sexually violent predators by definition pose a higher risk to the community at large and therefore mandated that upon their release from the Department of Corrections the community must be notified. Sex offender notification in Colorado happens in two ways. The first is passive and ongoing through the sex offender registration process which is a list maintained by local police departments. The second way is active via community notification for those offenders determined to be sexually violent predators by the courts or by the parole board. Most sex offenders in Colorado are supervised by the criminal justice system in our communities. Most sex offenders engage in crossover behavior which means they may have been arrested for one type of crime but be apt to commit another. Many sex offenders have no criminal history at all prior to their arrest. There is no typical sex offender but all tend to be deceptive, manipulative and secretive. 80 to 93% of sex offenses are committed by someone known to the victim. Sexual deviancy begins in mid to late adolescence. Sex offenses are not impulsive. They are usually carefully planned and most sex offenders are male. The community has a vested interest in helping offenders to be successfully managed in the community. Sex offenders have the same need for housing and employment as any other citizen. Any citizen who uses sex offender information to harass, threaten or intimidate an offender will be subject to criminal prosecution. There are approximately 16,500 registered sex offenders in the state of Colorado. About 65% of convicted sex offenders are placed in the community on probation. The remainder are in the Department of Corrections or Community Corrections. Offenders may be caught for one type of offense but be at a high risk to commit another type. Crime of conviction is only one indicator of risk. A sexually violent predator must register with the Denver Police Department Sex Offender Registration Unit every three months for the rest of their life. The offender's residents must be verified quarterly by the Denver Police Department. The full sex offender registration list is available by calling the Denver Police Department Identification Bureau at 720-913-6756. Convicted felons and those with multiple convictions are posted online at denvergov.org slash police. Remember, sexually violent predators do not represent all dangerous sex offenders. The community notification process and sex offender registration are not a complete deterrent to sexual assault. Now, here's a look at the newest sexually violent predator living in Denver.
