RENO, Nev. -- Investigators searching the home of serial killing suspect Joseph Naso found more than 4,000 photographs of lingerie-clad or naked women, often posed to look lifeless, sources say.
Many of the hundreds of women appear unconscious and in unnatural poses, sometimes in bondage, and they include all age groups and races.
Detectives have spent the past year correlating the photos with Naso's extensive handwritten notebooks and other documents detailing fantasies of torturing women. Fewer than half the women have been identified, but most of them have been found alive.
Investigators believe that Naso, a self-employed photographer who lived in the San Francisco Bay Area for decades, snapped the photos himself. Some prints date back to the 1960s, but most were taken fairly recently, sources say.
