New forensic testing has clarified evidence in a decades-old homicide case, with key support from the Sacramento County District Attorney\u2019s Office.<\/p>\n
The case stems from the 1966 killing of Marjorie Rudolph in San Rafael. A suspect, Laurel James Switzer, was identified early on but could not be tied to crime scene evidence using the forensic tools available at the time.<\/p>\n
In 2025, the San Rafael Police Department partnered with the Sacramento County District Attorney\u2019s Office to reexamine the case and advance DNA testing. Evidence was submitted to Othram, where scientists developed a DNA profile later matched to Switzer\u2019s family through genetic genealogy.<\/p>\n

Officials say the findings place Switzer at the scene. He died shortly after the homicide, leaving some details unresolved.<\/p>\n
