Such discovery may include items and biological materials from third parties, provided the party seeking discovery demonstrates that analysis of these items or biological material will, by a preponderance of the evidence, provide evidence material to the identification of a perpetrator of the crime.
If, in response to a motion made under subsection (c) of section 3, the court finds good cause for the moving party's inability to obtain items or information required under subsection (b) of said section 267A:3 and subsection (b) of section 278A:7, the court may order discovery to assist the moving party in identifying the location and condition of evidence or biological material that was obtained in relation to the underlying case, regardless of whether it was introduced at trial or would be admissible. The court, when considering such discovery requests, shall not require the establishment of a prima facie case for relief under Rule 30 of the Massachusetts Rules of Criminal Procedure.
