Naso was found guilty of killing Roxene Roggasch, 18, found near Fairfax in 1977; Carmen Colon, 22, found near Port Costa in 1978; Pamela Parsons, 38, found in Yuba County in 1993; and Tracy Tafoya, 31, found in Yuba County in 1994. (The same first and last initial in his victims' names brings to mind the unsolved Alphabet Murders in New York in the early 1970s. Naso was, at that time, living in update New York prior to relocating to the Bay Area.)
Naso picked the women up in his car, then later strangled, raped, and and then disposed of them. According to CBS SF, "Evidence against him included a handwritten list that prosecutors allege refers to at least seven women, including the four victims and some of the locations where their bodies were found."
We'll update as soon as we know more.
