Parabon Nanolabs are at the forefront of genetic genealogy and headed by CeCe Moore, already responsible for cracking long unsolved cold cases, including the brutal murders of Tanya Van Cuylenborg and Jay Cook (1987), April Tinsley (1988) and Virginia Freeman (1981). Approximately 50% of DNA loaded onto the GEDmatch database will fail to produce a match, while 20% can be cracked relatively quickly, and 30% with the assistance of police and appropriate manpower. Out of 300 DNA searches by Parabon Nanolabs nearly 100 cases have been solved, with several dozen having yet to result in arrests. As long as DNA and biological evidence exists in the case, a comprehensive and detailed phenotype report can be established and run through public genetic genealogy databases. They explain how their technique differs from searches in CODIS (Combined DNA Index System): "Our genetic genealogy service is somewhat like familial search, but it differs in three very important ways: (1) we only search public genetic genealogy databases, not government-owned criminal (STR profile) databases, such as CODIS; (2) because the DNA SNP profiles we generate contain vastly more information than traditional STR profiles, genetic relatedness can be detected at a far greater distance (see Snapshot Kinship Inference); and (3) because genetic genealogy matches can be cross-referenced by name with traditional genealogy sources, such as Ancestry.com, existing family trees can be used to expedite tree-building and case-solving. This technology and our innovative techniques combine to create a groundbreaking system for forensic human identification".
