Joseph Naso, the convicted serial killer known as the “Alphabet Killer," is now claiming he murdered 26 women, far more than the four killings for which he was found guilty. This startling revelation comes ahead of a new documentary set to be released next month.

Naso, 91, is serving time in California after being convicted in 2013 for the murders of four women whose first and last names started with the same letters.

The victims were Roxene Roggasch, 18, found near Fairfax in 1977; Carmen Colon, 22, killed in Port Costa in 1978; Pamela Parsons, 38, and Tracy Tafoya, 31, both murdered in Yuba County in the early 1990s. His case earned him the nickname “Alphabet Killer" because of this unusual pattern.

However, according to fellow inmate Bill Noguera, who befriended Naso over a decade at San Quentin prison, Naso boasted about killing 26 women in total.

Noguera revealed to the local ABC affiliate KGO that Naso even kept a “Greatest Hits" list of his victims.

Naso reportedly became angry when one of the murders on his list was wrongly blamed on another serial killer, Rodney Alcala — known as “The Dating Game Killer." Alcala was a fellow San Quentin inmate and was accused in media reports of killing one of Naso’s victims, Pamela Lambson, 19.

Naso had claimed he lured Lambson by pretending to be the official photographer for the Oakland A’s baseball team and took nude photos of her before killing her.

“She just drove me crazy about being an entertainer, and these photographs were because she was going to be a star, and she was dating one of the players from the A’s," Naso had told Noguera, according to the report.

Naso, a father of two and school photographer, was known to have taken staged photos of women pretending to be dead, including at least six of his victims before their deaths.

The new documentary, Death Row Confidential: Secrets of a Serial Killer, premieres on Oxygen on September 13. It features interviews with journalists and inmates, including Dan Noyes, the only journalist to have ever interviewed Naso. The series also reveals how Naso’s former inmates Ken Mains and Bill Noguera have helped solve several of his cold cases, providing closure for victims’ families.
