to 133.717 if the evidence: (a) Is collected as part of a criminal investigation into a covered offense; or (b) Is otherwise in the possession of the custodian and reasonably may be used to incriminate or exculpate any person for a covered offense. (2) When a custodian is required to preserve biological evidence under subsection (1) of this section, the custodian shall preserve the evidence in an amount and manner that is sufficient to develop a DNA profile. Except as otherwise provided in ORS 133.705 to 133.717, the biological evidence must be preserved: (a) If the covered offense is aggravated murder, murder, rape in the first degree, sodomy in the first degree or unlawful sexual penetration in the first degree, for 60 years from the date each person is convicted of the offense or until each person convicted of the offense has died, whichever is earlier. (b) If the covered offense is aggravated vehicular homicide, manslaughter in the first degree or manslaughter in the second degree, until each person convicted of the offense has served the person’s sentence. (c) If no person is convicted of the covered offense or the law enforcement agency investigating the covered offense closes the case for a reason other than the conviction of a person, until the expiration of the statute of limitations. (3) A custodian is not required to preserve physical evidence solely because the physical evidence contains biological evidence if the physical evidence is of such a size, bulk or physical character as to render retention impracticable. When the retention of physical evidence is impracticable, the custodian shall remove and preserve portions of the physical evidence likely to contain biological evidence in a quantity sufficient to permit future DNA testing before returning or disposing of the physical evidence. (4) Upon the conclusion of any trial or hearing involving a covered offense, the court shall return any biological evidence in the possession of the court to the custodian responsible for preserving the biological evidence under ORS 133.705 to 133.717, unless the evidence was collected by the defense. If the evidence was collected by the defense, the court shall return the evidence to the attorney for the defendant. (5) If a custodian is required to preserve biological evidence under ORS 133.705 to
