Any person required to provide a DNA sample pursuant to this section shall be required to provide such sample, without the right of refusal, at a collection site designated by the Missouri state highway patrol and the department of corrections. Authorized personnel collecting or assisting in the collection of samples shall not be liable in any civil or criminal action when the act is performed in a reasonable manner. Such force may be used as necessary to the effectual carrying out and application of such processes and operations.

The division of probation and parole shall recommend that an individual on probation or parole who refuses to provide a DNA sample have his or her probation or parole revoked. In the event that a person's DNA sample is not adequate for any reason, the person shall provide another sample for analysis.
4. The procedure and rules for the collection, analysis, storage, expungement, use of DNA database records and privacy concerns shall not conflict with procedures and rules applicable to the Missouri DNA profiling system and the Federal Bureau of Investigation's DNA databank system.
5. Unauthorized use or dissemination of individually identifiable DNA information in a database for purposes other than criminal justice or law enforcement is a class A misdemeanor.
6. Implementation of sections 650.050 to 650.100 shall be subject to future appropriations to keep Missouri's DNA system compatible with the Federal Bureau of Investigation's DNA databank system.
7. All DNA records and biological materials retained in the DNA profiling system are considered closed records pursuant to chapter 610. All records containing any information held or maintained by any person or by any agency, department, or political subdivision of the state concerning an individual's DNA profile shall be strictly confidential and shall not be disclosed, except to:
(1) Peace officers, as defined in section 590.010, and other employees of law enforcement agencies who need to obtain such records to perform their public duties;
(2) The attorney general or any assistant attorneys general acting on his or her behalf, as defined in chapter 27;

Such records shall be considered strictly confidential and shall only be released as authorized by this section.
9.
(1) An individual may request expungement of his or her DNA sample and DNA profile through the court issuing the reversal or dismissal, or through the court granting an expungement of all official records under section 568.040. A certified copy of the court order establishing that such conviction has been reversed, guilty plea has been set aside, or expungement has been granted under section 568.040 shall be sent to the Missouri state highway patrol crime laboratory. Upon receipt of the court order, the laboratory will determine that the requesting individual has no other qualifying offense as a result of any separate plea or conviction and no other qualifying arrest prior to expungement.
(2) A person whose DNA record or DNA profile has been included in the state DNA database in accordance with this section and sections 650.050, 650.052, and 650.100 may request expungement on the grounds that the conviction has been reversed, the guilty plea on which the authority for including that person's DNA record or DNA profile was based has been set aside, or an expungement of all official records has been granted by the court under section 568.040.
(3) Upon receipt of a written request for expungement, a certified copy of the final court order reversing the conviction, setting aside the plea, or granting an expungement of all official records under section 568.040, and any other information necessary to ascertain the validity of the request, the Missouri state highway patrol crime laboratory shall expunge all DNA records and identifiable information in the state DNA database pertaining to the person and destroy the DNA sample of the person, unless the Missouri state highway patrol determines that the person is otherwise obligated to submit a DNA sample. Within thirty days after the receipt of the court order, the Missouri state highway patrol shall notify the individual that it has expunged his or her DNA sample and DNA profile, or the basis for its determination that the person is otherwise obligated to submit a DNA sample.
(4) The Missouri state highway patrol is not required to destroy any item of physical evidence obtained from a DNA sample if evidence relating to another person would thereby be destroyed.
(5) Any identification, warrant, arrest, or evidentiary use of a DNA match derived from the database shall not be excluded or suppressed from evidence, nor shall any conviction be invalidated or reversed or plea set aside due to the failure to expunge or a delay in expunging DNA records.
10. When a DNA sample is taken from an individual pursuant to subdivision (2) of subsection 1 of this section and the prosecutor declines prosecution and notifies the arresting agency of that decision, the arresting agency shall notify the Missouri state highway patrol crime laboratory within ninety days of receiving such notification. Within thirty days of being notified by the arresting agency that the prosecutor has declined prosecution, the Missouri state highway patrol crime laboratory shall determine whether the individual has any other qualifying offenses or arrests that would require a DNA sample to be taken and retained. If the individual has no other qualifying offenses or arrests, the crime laboratory shall expunge all DNA records in the database taken at the arrest for which the prosecution was declined pertaining to the person and destroy the DNA sample of such person.
11. When a DNA sample is taken of an arrestee for any offense listed under subsection 1 of this section and charges are filed:
(1) If the charges are later withdrawn, the prosecutor shall notify the state highway patrol crime laboratory that such charges have been withdrawn;
(2) If the case is dismissed, the court shall notify the state highway patrol crime laboratory of such dismissal;
(3) If the court finds at the preliminary hearing that there is no probable cause that the defendant committed the offense, the court shall notify the state highway patrol crime laboratory of such finding;
(4) If the defendant is found not guilty, the court shall notify the state highway patrol crime laboratory of such verdict.

If the state highway patrol crime laboratory receives notice under this subsection, such crime laboratory shall determine, within thirty days, whether the individual has any other qualifying offenses or arrests that would require a DNA sample to be taken. If the individual has no other qualifying arrests or offenses, the crime laboratory shall expunge all DNA records in the database pertaining to such person and destroy the person's DNA sample.
