(4)  Any person who, since July 1, 1979, has been found not guilty as a result of mental disease or defect of any offense referenced in section 589.414;

(5)  Any juvenile certified as an adult and transferred to a court of general jurisdiction who has been adjudicated for an offense listed under section 589.414;

(6)  Any juvenile fourteen years of age or older at the time of the offense who has been adjudicated for an offense which is equal to or more severe than aggravated sexual abuse under 18 U.S.C. Section 2241, which shall include any attempt or conspiracy to commit such offense;

(7)  Any person who is a resident of this state who has, since July 1, 1979, been or is hereafter adjudicated in any other state, territory, the District of Columbia, or foreign country, or under federal, tribal, or military jurisdiction for an offense which, if committed in this state, would constitute an offense listed under section 589.414, or has been or is required to register in another state, territory, the District of Columbia, or foreign country, or has been or is required to register under tribal, federal, or military law; or

(8)  Any person who has been or is required to register in another state, territory, the District of Columbia, or foreign country, or has been or is required to register under tribal, federal, or military law and who works or attends an educational institution, whether public or private in nature, including any secondary school, trade school, professional school, or institution of higher education on a full-time or on a part-time basis or has a temporary residence in Missouri.  “Part-time” in this subdivision means for more than seven days in any twelve-month period.

Person entering Alford plea to one of the enumerated offenses is subject to sex offender registration. Haffner v. Saulters, 77 S.W.3d 45 (Mo.App. E.D.).(2005) Sex offender registration statutes are non-punitive civil regulation and thus do not constitute an ex post facto punishment; sections also do not violate the due process rights of registrants. R. W. v. Sanders, 168 S.W.3d 65 (Mo.banc).(2006) Sections 589.400 to 589.425 are constitutional under ex post facto, due process, equal protection, bill of attainder, and special law provisions; however, application of registration requirement to persons who pled guilty or were found guilty prior to sections’ effective date of January 1, 1995, violates constitutional ban on laws retrospective in operation. Doe v. Phillips, 194 S.W.3d 833 (Mo.banc). (2023) Section mandates lifetime registration requirement in Missouri if the offender "has been" subject to federal registration requirements under Sex Offender Registration and Notification Act, even if that federal obligation has expired.  Smith v. St. Louis County Police, 659 S.W.3d 895 (Mo.banc).

International Travel

Missouri will ensure that the offender reports any intent to travel internationally 21 days in advance and to submit information concerning such travel to the Missouri State Highway Patrol who will then notify the appropriate Federal agency on the offender’s intent.

Protected Witnesses

Missouri will take measures to ensure a protected witness’s true name is excluded from the public website or may identity the registrant on the public website by his or her new identity or data.
