Law enforcement's access to genealogical databases is limited to GEDmatch (approx. 1.5 million people) and Family Tree DNA (approx. 1.25 million people), with only a fraction of GEDmatch users opting into law enforcement matching (around 500,000). This small sample size makes identifying close relatives challenging, often requiring genealogical work with distant cousins (third to sixth cousins or beyond).
Impact: High. The constrained size of these databases presents a significant hurdle, demanding sophisticated genealogical techniques and extensive research to bridge the gaps and identify potential suspects.
