A murderer is taunting the mother of his schoolboy victim from prison – accusing her of abusing her son and lying about her grief.

Lewis Daynes, 20, has reportedly posted in two Google blogs blaming the family of Breck Bednar for his death, despite a ban on prisoners using social media.

He mocks Breck's mother, Lorin LaFave, for her claim to have been incapacitated with grief. And he accuses the media of falsely portraying him as a paedophile.

Miss LaFave has reported Daynes to police for harassment but was told that no action will be taken, according to The Sun.

She said: 'The things he is saying are so hurtful. It makes a mockery of the system, that a murderer serving life can actually do this from inside a prison. It is another twist of the knife.'

Daynes lured 14-year-old Breck to his flat and launched a 'sexually or sadistically motivated' knife attack in February 2014.

But in the online posts Daynes claims Breck attacked him first – because the younger boy had anger problems caused by his family.

He also claims her violent alcoholism wrecked Breck’s self-esteem, adding: 'I believe this is why he formed this strong emotional attachment to me.'

It was revealed earlier this year that Daynes had begun taunting Miss LaFave from behind bars.

In January she told the Daily Mail at the time that the killer, who was jailed for life last year, was lying to torment her.

'Everything that he does is with the intention of controlling and manipulating people,' said the 48-year-old.

'He is a convicted murderer who is able to use the weapon of the internet to harass my family. He is taunting me from behind bars and the system is allowing him to do it.'

It is unclear how Daynes posted the blogs, which could be seen on his Twitter account.

The Prison Service has said in the past that his cell was searched after the posts appeared and that no electronic devices were found.

A spokesman added: 'Prisoners are banned from using mobile phones and social media. If they break the rules they will be disciplined and can have time added on to their sentence.'

The first note was posted on November 26. Miss LaFave, who was born in the United States, believes it was timed to clash with Thanksgiving celebrations that day.

It claims to offer comfort to Breck's family by saying 'his death ensued seconds after the injury' in a fight.

But the blog then alleges the teenager was subjected to 'drunken, abusive behaviour' at home which drove him 'away from family life and towards the virtual world'.
