What the Case Established
The Golden State Killer case established several things that are not always clearly distinguished in public discussion.
It established, through a guilty plea entered in a court of law, that Joseph James DeAngelo committed thirteen murders and additional crimes across multiple California counties between 1975 and 1986. The guilty plea is the legal determination; the facts admitted in the plea are the legally established account.
It established that investigative genetic genealogy, when applied with appropriate corroboration, can provide investigative leads in cold cases where conventional methods have not produced identifications. The case does not establish that the method will always work, that it is appropriate in all circumstances, or that it should be used without ethical guidelines and oversight.
It established that biological evidence preserved across decades can remain useful for modern forensic analysis, and that the investment in evidence preservation is worthwhile even when the technology to use that evidence effectively does not yet exist at the time of preservation.
And it established, through the words of the survivors and families who spoke at the sentencing, that the resolution of a criminal case is not the same as the resolution of the harm the case was about. The legal system produced an outcome. The people who lived through the crimes produced the meaning of that outcome, in their own words, in their own time.
Jane Carson-Sandler’s effective life sentence. Kris Pedretti’s lost girl who did not stay lost. Jennifer Carole’s silver linings found within forty years of grief. Elizabeth Hupp’s forty-six years without her father. Gay Hardwick’s forty-two years of memory. Victor Hayes’s unanswered questions.
