Hammer attack murderer Michael Stone has accepted a sick challenge from a fellow monster to ‘prove’ who battered Lin Russell and daughter Megan to death 14 years ago.

Stone says he is willing to take a lie detector test if serial killer Levi Bellfield provides the DNA he says would clear his name.

Stone, 57 – jailed after a fellow lag said he confessed to the crime while awaiting trial – whines in a prison letter “I want justice with the real murderer exposed.

“I’m condemned to life in prison because of a lie.”

Stone’s DNA was never found at the scene of the savage attack in Chillenden, Kent, in 1996.

And his legal team now wants samples from Bellfield, 52, to test against exhibits.
