Naso, 79, of Reno, Nev., was convicted Aug. 20 of strangling Roxene Roggasch, Tracy Tafoya, Pamela Parsons and Carmen Colon. Their bodies were found off of rural roads in Contra Costa, Marin and Yuba counties between 1977 and 1994.
The jury started deliberations at 10:15 a.m. today after Judge Andrew Sweet allowed Naso to reopen his closing argument, which he had completed Monday.
Naso addressed the jury for about six minutes and again asked them not to impose the death penalty. He faces life without parole if the jury does not recommend the death penalty.
