§ 750.462gTestimony of victim; admissibility of expert testimony as to human trafficking

victim's behavior.
 Sec. 462g.
    (1) The testimony of a victim is not required in a prosecution under this chapter. However, if
 a victim testifies, that testimony need not be corroborated.
    (2) Expert testimony as to the behavioral patterns of human trafficking victims and the
 manner in which a human trafficking victim's behavior may deviate from societal expectations
 is admissible as evidence in court in a prosecution under this chapter if the expert testimony is
 otherwise admissible under the rules of evidence and laws of this state.
    (3) A victim or complainant must not be excused from attending and testifying or producing
 any books, papers, or other documents before a court or magistrate on an investigation,
 proceeding, or trial for a violation of this chapter on the grounds that the testimony or
 evidence may tend to incriminate the victim or complainant. Truthful testimony, evidence, or
 other truthful information elicited under this section and any information derived directly or
 indirectly from that truthful testimony, evidence, or other truthful information must not be
 used against the victim or complainant in a criminal case, except for impeachment purposes or
 in a prosecution for perjury or otherwise failing to testify or produce evidence as required.
