Forensic genetic genealogy links crime-scene DNA to relatives via genealogy databases.

The Claim

Forensic genetic genealogy can generate investigative leads by linking a crime-scene DNA sample to biological relatives using genealogy records.

Verified by Lenz ·

The Short Version

Authoritative sources describe forensic genetic genealogy exactly this way: crime-scene DNA can be compared against genealogy databases to find biological relatives, and genealogical records can then be used to build family trees and generate investigative leads. The claim is accurate as a statement of capability, though the method does not by itself prove identity or guilt.

Caveats

  • Generating a lead is not the same as confirming identity; follow-up investigation and direct DNA comparison are typically required.
  • The method's effectiveness depends on usable DNA, the presence of relatives in searchable databases, and applicable legal or policy restrictions.
  • Privacy and consent rules limit which genealogy databases law enforcement may search and under what conditions.
