A young San Diego mom's murder has been solved after four decades through genetic genealogy, police say.
A young San Diego mom's murder has been solved after four decades through the novel investigative technique known as genetic genealogy, according to police.On March 21, 1979, Barbara Becker, a 37-year-old wife and mother, was found dead in her living room by her 7- and 9-year-old sons when they returned from school, according to San Diego police.
The young mom suffered sharp force injuries and it appeared she "put up a tremendous fight for her life," police said in a news release Thursday. The release added that a blood trail was left behind, indicating her killer was injured in the fight.When DNA technology became available, the killer's profile left behind at the crime scene was uploaded to CODIS -- the Combined DNA Index System, a law enforcement database -- but no matches were found, police said.
The break in the case came in October 2018, when San Diego investigators reached out to the FBI’s investigative genealogy team. "The group worked together and were eventually able to identify a potential suspect using public access genealogical databases," according to police.takes the DNA an unknown killer left behind at a crime scene and identifies a suspect by tracing the family tree through his or her family members, who voluntarily submit their DNA to public genealogy databases.
This allows police to create a much larger family tree than using DNA submissions to law enforcement databases like CODIS, in which an exact match to the suspect is needed in most states, according to CeCe Moore, chief genetic genealogist with Parabon, a company that provides DNA analysis for law enforcement but was not involved in the Becker case.
