The mother of Soham killer Ian Huntley reportedly wants her son to be put to death because of his horrific crimes.
Huntley murdered 10-year-olds Holly Wells and Jessica Chapman
Lynda Nixon's comments in the Sun came as Huntley began a life sentence for the murders of schoolgirls Holly Wells and Jessica Chapman in August 2002.
She said her son's actions were "unforgivable" and he should pay for them with his own life.
Ms Nixon, 49, also said she had thought Huntley was guilty because she "saw it in his eyes" when he was arrested.
Ms Nixon told the paper: "I truly wish we had capital punishment.
"I believe Ian should not live after what he's done."
She added: "He's my baby boy and I love him but he deserves to be punished. He deserves to be strung up for what he's done.
"I wish there was an electric chair in this country that they could put him in and that would be the end of it."
Huntley was given two life sentences at the Old Bailey for the murders.
He is to undergo psychiatric tests to assess whether he should be held in a secure mental hospital or jail.
Ms Nixon, 49, who was divorced from Huntley's father Kevin but has since been reunited, went into hiding when her son and his then fiancee Maxine Carr were arrested last summer.
Maxine Carr, 26, was given three-and-a-half years for conspiring to pervert the course of justice but cleared of two counts of assisting an offender.
Ms Nixon said she knew about one rape allegation against her son, but he had insisted the girl in that case was lying.
When Huntley was arrested by police at his parents' home, Ms Nixon said she looked into her son's eyes and "just knew he'd done it".
She added: "It wasn't what he said. It's what he didn't say. I told the
police straight away, `I think he's done it, I know he's done it'."
Ms Nixon also told the newspaper that when her son telephoned her after his conviction for murder, she berated him and called him a liar.
Her damning remarks come amid concerns about how Huntley was allowed to work with children despite past allegations of rape and underage sex.
Home Office minister Hazel Blears said in a Commons statement on Thursday that police forces must have better systems for inputting arrest and conviction details.
She said a year-long study of forces' performance was "not encouraging", but that new practices had been put in place to overcome failings.
Home Secretary David Blunkett has ordered an inquiry into the effectiveness of intelligence and vetting used by the Cambridgeshire and Humberside forces to examine Huntley's background.
The police and social services are also carrying out investigations into their respective roles in the case.
