Notorious death row inmates at San Quentin State Prison in California include David Joseph Carpenter, Charles Ng, Joseph Naso and Scott Peterson as of 2015. Over 700 death row inmates await execution at San Quentin, although California last executed someone in 2006.
David Joseph Carpenter killed seven people in 1980 and 1981, all along trails in Marin and Santa Cruz Counties. He arrived at San Quentin after his conviction in the mid 1980s.
Charles Ng entered death row after his 1999 conviction for 11 murders that occurred in the early 1980s. Ng's co-serial killer, Leonard Lake, killed himself shortly after his arrest. Ng and Lake killed as many as 25 people in total at Lake's cabin in the Sierra Nevada foothills.
Convicted of strangling and raping six women between 1978 and 1994, Joseph Naso arrived on death row in 2011. Two of the convictions occurred after he arrived at San Quentin. Many of Naso's murders became famous as the "Alphabet Murders," so named because the victims' first and last names began with the same letter.
Scott Peterson entered death row after his 2004 conviction for the 2002 murder of his wife and unborn child in Modesto. As of 2015, Peterson's case remains on appeal to the California Supreme Court. Multiple television movies portray the murder and investigation into Peterson.
