Every offender convicted or released after 1-1-97, of a sexually oriented offense is presumed to be a Sexual Predator unless the judge, in a required hearing, determines otherwise by clear and convincing evidence. Judges may consider any prior convictions, victim's age, use of drugs or alcohol to impair the victim, sexually deviant behavior, whether threats or acts of torture were used, offender personality disorder, or other behavioral characteristics to determine the offender's status. Judges may later determine to drop the offender's predator status. Hearsay evidence is admissible.

Each crime has certain sentence options allowed by law, but sexual predators must be sentenced to a minimum two years and up to life in prison (not local jail). The judge can later reduce the sentence or the "predator" status. Offenders convicted with a sexually violent predator specifications must be sentenced to life in prison without parole when that option is available for the crime (except for death penalty cases). Any mandatory sentences for firearms or repeat violent offenders, or prior sentences for sexually violent predator convictions must be served consecutively. Offenders must submit to DNA collection.

All offenders must also personally register within 7 days prior to establishing residence or when visiting for more than 7 days. Offenders who are not "habitual" or "predator" offenders are not subject to victim and community notification.
