SAN RAFAEL, Calif. (AP) — Testimony is resuming Thursday in the preliminary hearing of a former photographer accused of killing four Northern California women with matching initials in the 1970s and 1990s.

Seventy-eight-year-old Joseph Naso is acting as his own lawyer in what is likely to be a death penalty case.

He has pleaded not guilty to four murder charges involving slayings of prostitutes the 1970s and 1990s.

Nevada Department of Public Safety Det. Richard Brown is the lead investigator in the "Double Initials" killings.

On Wednesday, Naso listened as Marin County prosecutor Dori Ahana and Brown detailed dozens of sexual and violent photographs of women seized from his home.
