A structured law-enforcement framework for evaluating, advancing, and defending cold cases using DNA evidence and forensic genetic genealogy — developed by retired detective and sergeant Christine Burke.
Without a structured strategy, DNA testing alone does not move cases forward. Investigators need a clear investigative path before evidence is sent to a laboratory. The HELIX Method addresses that gap by treating forensic genetic genealogy as an investigation — from assessment through defensibility.
Not every case is appropriate for FGG. The framework begins with an honest assessment of viability.
Re-evaluate the investigation through a structured review of the evidence, investigative history, and DNA viability. Outcome: a clear-eyed picture of whether a case is a candidate for FGG — and an honest assessment when it is not.
Determine the correct testing approach — including whether STR or SNP methods fit — before evidence is sent to a laboratory. Outcome: a deliberate testing strategy that reduces preventable spending, delays, and duplicated effort.
Apply genealogical research together with law-enforcement investigative skills to generate investigative leads. Outcome: documented investigative direction that the agency can lawfully develop — leads, not confirmed identities.
Ensure the investigative pathway is corroborated and properly documented for prosecutorial review, courtroom scrutiny, and medical-examiner acceptance. Outcome: work that can withstand scrutiny, with leads independently corroborated and a defensible record of investigative decisions.
