Suspected serial killer charged in slayings of four young women

| April 12, 2011

A Nevada man is being held in Marin County on suspicion of murdering four young women, two in the Bay Area, between the late 1970s and early 1990s, prosecutors said Tuesday.

Marin County District Attorney Ed Berberian said at a brief news conference in San Rafael the murders included the 1977 slaying of Roxene Roggasch, whose body was found on White’s Hill near Fairfax.

Joseph Naso, 77, of Reno, was arrested Monday by Marin County authorities after being released from El Dorado County Jail in South Lake Tahoe where he had been in custody on unrelated charges. He is being held at Marin County Jail on a no-bail status.

Berberian said Roggasch’s killing remained unsolved until Naso’s arrest in Reno in April 2010, when investigators found items linked to Naso “that implicated him in multiple murders of young women.”

Naso is also suspected of murdering Carmen Colon, whose body was found near Port Costa in Contra Costa County in 1978, as well as two women in Yuba County – Pamela Parsons and Tracy Tofoya, whose bodies were found in 1993 and 1994, according to Berberian.

Naso is scheduled to be arraigned Wednesday afternoon in Marin County Superior Court on four counts of murder with special-circumstances allegations of multiple murders that would make him eligible for the death penalty, Berberian said.

Berberian said an investigation is ongoing. He would not take questions at the news conference.
