I’ve been thinking a lot about how important DNA evidence is—not just for solving crimes, but for giving families some kind of closure, even decades later.
Renee Cuevas, a 27-year-old woman who was murdered back in 1989 near the old El Toro Marine Base in Irvine, CA. Her case went cold for years. Her family had no answers, just a huge hole in their lives.
Then in 2003, DNA linked her murder to another case from 1987—Shannon Lloyd, who was also killed in a brutal assault. But even then, they didn’t know who the killer was. It wasn’t until 2021, thanks to advances in genetic genealogy, that they were finally able to identify the guy: Reuben Smith. Sadly (or maybe ironically), he had already died by suicide in 1999. So there wasn’t going to be a trial or justice in the traditional sense.
Still, just knowing who did it gave both families answers. After more than 30 years of not knowing, they could finally start to grieve with some kind of resolution.
What really struck me is that the key DNA match came from a woman who survived one of his attacks in 1998. Her courage to come forward—and the fact that DNA was collected—ended up solving two cold cases and bringing peace to two grieving families.
It just makes me realize how powerful DNA is, not just for catching people, but for acknowledging the pain of victims' families and giving them a chance to heal. I hope we keep investing in this kind of technology and cold case work, because it really matters.
On the morning of February 19, 1989, the body of 27-year-old Hispanic woman Renee Cuevas was found along Lambert Road near the former El Toro Marine Base in Irvine, California. The case went cold after initial investigative efforts failed to produce a suspect, and family members remembered her for her dimples and warm personality.
In 2003, Orange County Crime Lab scientists linked Cuevas’s murder by DNA to the 1987 sexual assault and strangulation of 23-year-old Shannon Rose Lloyd in Garden Grove, indicating the same perpetrator committed both crimes. Investigative limits at the time prevented identification.
Advances in investigative genetic genealogy led authorities in 2021 to a suspect, Reuben J. Smith, who had lived in Orange County in the 1980s and later in Las Vegas. DNA from a July 1998 Las Vegas arrest for sexual assault and attempted murder matched samples from the Cuevas and Lloyd scenes. Smith died by suicide in 1999, so no prosecution was possible. If anyone knew Renee or has information about her life or those years in Orange County, please share what you know.
