4. The Investigating Agency has requested that the forensic unknown STIR DNA profile, if qualified, be uploaded into the Combined DNA Index System (CODIS) and no hit has resulted from routine searches. 5. If a qualifying forensic unknown STIR DNA profile exists, and absent circumstances that may limit future testing capabilities or delay the Investigation where the public safety risk is critical, the Investigating Agency should consider submitting a request for a Familial Search of that profile to Cal-DOJ, after consulting with OCDA. 6. If the forensic unknown STIR DNA profile does not qualify for a CODIS upload, the Investigating Agency has consulted with OCDA and the Orange County Crime Lab (OCCL), and noted the reason why the forensic unknown STIR DNA profile does not qualify for a CODIS upload in the case file. UNDERTAKING INVESTIGATIVE GENETIC GENEALOGY 7. The Investigating Agency has consulted with OCDA and both agencies agree that IGG is an appropriate and necessary step in the development of investigative leads and to protect public safety. IGG shall be conducted in a lawful manner consistent with federal Constitutional jurisprudence. 8. The Investigating Agency shall consult with OCCL to determine if the forensic unknown sample is suitable (i.e., quantity, quality, degradation, mixture status, etc.) for Single -Nucleotide Polymorphism (SNP) or other testing. 9. The forensic unknown sample used to develop a SNP or other DNA profile shall be attributable to the perpetrator in the case or to unknown human remains. 10. If the crime is solved while IGG is ongoing, IGG will cease immediately and the Investigating Agency will take all reasonable steps to ensure that any testing cease, any samples/evidence be returned to the Investigating Agency or OCCL, and any profiles/data shall be removed from any genealogical websites. 11. The Investigative Agency agrees that no arrest will be made based solely on the identification of a potential suspect from IGG. The identification is an investigative lead or "pointer" only and must be confirmed by STIR DNA testing through a legally obtained sample verifying the suspect's identity. 12. The Investigative Agency should consult with OCDA prior to obtaining any DNA sample from a potential suspect identified by IGG. 13. The Investigating Agency will consult with OCDA if it becomes necessary to obtain a DNA sample from an individual other than the potential suspect (e.g., an Individual who has been determined to be genetically related to the potential suspect). Such samples shall be legally obtained and the Investigating Agency shall obtain written, Informed consent from that individual, unless extenuating circumstances exist (i.e., investigation could be compromised). If extenuating circumstances exist and third OCDA IGG MOU 3.3.2020
