Given the mobility of the sex offender population, who often move several times per year, management of these offenders can be challenging, particularly when it comes to transferring sex offender information between jurisdictions. In response, Douglas County Government, in collaboration with four Douglas County-based law enforcement agencies, cooperatively designed a web-based application called SOTAR that provides law enforcement agencies with an effective means of managing sex offenders, sharing sex offender data, and transferring sex offenders between jurisdictions. The system, built in-house by Douglas County Information Technology, also provides the public a seamless view of sex offenders in their area without regard to jurisdictional boundaries.
