DNA Breaks 60‑Year‑Old Murder Mystery
# **Cold Case Cracked After 57 Years: DNA Solves 1966 Murder in San Rafael**
## **A Murder That Shook a Community**
On **February 1, 1966**, a woman in **San Rafael, California**, was brutally killed in her home while her husband—a prominent **bank president**—was away for surgery. The victim was alone when an unknown intruder struck. Investigators found **three Salem cigarettes** in a table ashtray, a brand she never smoked, leaving detectives with a chilling clue.
## **The Prime Suspect Vanishes**
Police quickly zeroed in on **Laurel James Switzer**, a man who vanished the day after the murder—only to be found dead by suicide in Sacramento. Without modern forensic technology, investigators couldn’t definitively place him at the scene. The case went cold.
## **A Decades-Long Pursuit for Justice**
In 2008, a retired officer stumbled upon the still-open case while speaking with a concerned woman. He revisited the evidence room, where the decades-old cigarettes were preserved. A 2010 attempt to collect DNA from a Switzer relative failed, but fate had another plan.
By 2023, a different relative agreed to provide a sample. Detectives turned to Othram Inc., a Texas lab specializing in genome sequencing, which generated a detailed DNA profile. Using forensic genealogy software, they matched the sample to Switzer—proving he had been at the crime scene.
Closure After 57 Years
With this breakthrough, detectives finally closed a case that had haunted families for six decades. The victim’s husband had been the president of Bank of America in San Rafael, and Switzer’s wife worked there—a connection, but no clear motive emerged.
A retired detective later told the victim’s daughter that the family was deeply grateful for the closure. He hopes this case will inspire more cold-case reviews as forensic technology advances.
