1. Any person who has been adjudicated a delinquent by a juvenile court for committing or attempting to commit a sex-related offense which if committed by an adult would be considered a felony offense pursuant to chapter 566, RSMo, including, but not limited to, rape, forcible sodomy, child molestation and sexual abuse, shall be considered a juvenile sex offender and shall be required to register as a juvenile sex offender by complying with the registration requirements provided for in this section. This requirement shall also apply to any person who is or has been adjudicated a juvenile delinquent in any other state or federal jurisdiction for committing or attempting to commit offenses which would be proscribed herein.
2. Any state agency having supervision over a juvenile required to register as a juvenile sex offender or any court having jurisdiction over a juvenile required to register as a juvenile sex offender, or any person required to register as a juvenile sex offender, shall, within ten days of the juvenile offender moving into any county of this state, register with the juvenile office of the county. If such juvenile offender changes residence or address, the state agency, court or person shall inform the juvenile office within ten days of the new residence or address and shall also be required to register with the juvenile office of any new county of residence. Registration shall be accomplished by completing a registration form similar to the form provided for in section 589.407, RSMo. Such form shall include, but is not limited to, the following:
1. (1) A statement in writing signed by the juvenile, giving the juvenile's name, address, Social Security number, phone number, school in which enrolled, place of employment, offense which requires registration, including the date, place, and a brief description of such offense, date and place of adjudication regarding such offense, and age and gender of the victim at the time of the offense; and
2. (2) The fingerprints and a photograph of the juvenile.
3. Juvenile offices shall maintain the registration forms of those juvenile offenders in their jurisdictions who register as required by this section. Information contained on the registration forms shall be kept confidential and may be released by juvenile offices to only those persons and agencies who are authorized to receive information from juvenile court records as provided by law, including, but not limited to, those specified in section 211.321. State agencies having custody of juveniles who fall within the registration requirements of this section shall notify the appropriate juvenile offices when such juvenile offenders are being transferred to a location falling within the jurisdiction of such juvenile offices.
4. Any juvenile who is required to register pursuant to this section but fails to do so or who provides false information on the registration form is subject to disposition pursuant to this chapter. Any person seventeen years of age or over who commits such violation is guilty of a class A misdemeanor as provided for in section 211.431.
5. Any juvenile to whom the registration requirement of this section applies shall be informed by the official in charge of the juvenile's custody, upon the juvenile's discharge or release from such custody, of the requirement to register pursuant to this section. Such official shall obtain the address where such juvenile expects to register upon being discharged or released and shall report the juvenile's name and address to the juvenile office where the juvenile will be required to register. This requirement to register upon discharge or release from custody does not apply in situations where the juvenile is temporarily released under guard or direct supervision from a detention facility or similar custodial facility.
6. The requirement to register as a juvenile sex offender shall terminate upon the juvenile offender reaching age twenty-one, unless such juvenile offender is required to register as an adult offender pursuant to section 589.400, RSMo.
