Serial killer Steven Gordon is pleading for death

A SERIAL killer who murdered four women revealed he reads a letter from his niece to remind him of how badly he "screwed up".

Speaking for the first time from his prison cell on California's death row, Steven Dean Gordon said what he did was beyond evil.

In the interview, which airs tomorrow night, Gordon tells Dateline NBC's Keith Morrison he received a letter from his niece, who didn't hold back her disgust over his vile crimes.

Gordon was convicted of murdering four women with ties to prostitution in 2012 and 2013. Jurors found special circumstances of murder during a kidnapping and multiple murders, making him eligible for the death penalty.

Authorities say Gordon was wearing a GPS tracking device for prior offences during three of the murders and carried them out with fellow sex offender Franc Cano, 30, who is being tried separately. Cano will go on trial later this year.

"I love my niece more than anything," he tells Morrison. "She just said, 'How could you do that to four women? You guys are evil. You're disgusting,"' he said.

"It was pretty bad."

He said he still has the letter which he reads periodically.

The convicted killer then goes on to clarify that he more than "screwed up" and only used the term because he didn't want to say what he was really thinking.

"It's beyond evil what happened," he said.

"What me and him did was beyond evil."

Murder victims: Jarrae Nykkole Estepp, 21, of Oklahoma; Martha Anaya, 28, Santa Ana; Kianna Jackson, 20, of Las Vegas; and Josephine Monique Vargas, 34, of Santa Ana.

Gordon has previously admitted that he deserved to die for what he did.

Both men were charged with the deaths of Jarrae Nykkole Estepp and three women who went missing in Santa Ana - Kianna Jackson, 20, Josephine Monique Vargas, 34 and Martha Anaya, 28.

Prosecutors charged both men with rape but later dropped those charges against Gordon without explanation.

One of the victim's bodies was found at a recycling centre in Anaheim, and investigators later tied the case to the earlier disappearance of three other women in Southern California.

The other three bodies have never been found.

Gordon was sentenced to death in February this year after begging for the death penalty for two years.

The 47-year-old openly admitted to the abductions and murders of four women and as victim impact statements were read out in court, he admitted how sorry he was for his crimes, the Orange Country Register reported.

"I'm sorry for everything, but those are hollow words compared to what those women went through," Gordon said.

"I truly am sorry. I know that doesn't mean anything, but I'm sorry."

Cano and Gordon were registered sex offenders after being convicted in separate cases of lewd and lascivious acts with a child under 14.

Gordon was convicted in 1992 and also has a 2002 kidnapping conviction, while Cano's conviction dates to 2008.
