Moodley has changed his story so many times before. Whatever new "evidence" he tries to bring forward appears to be a product of his imagination.

The most unfortunate result of Moodley's constant change of his confession is that we'll never know the truth even if he does finally tell it.

This week, he gave a totally new account of how Matthews was killed - an horrific one of how three unknown drug dealers allegedly coordinated Matthews' kidnapping and murder.

He also sought to divert attention by trying to discredit investigating officer Piet Byleveld, who was widely praised for solving the mystery of Matthews' murder at the time of Moodley's arrest.

We are tempted to believe other people were indeed involved in the murder.

We have always maintained that Moodley could not have carried out the murder alone.

But it is unbelievable - and inconceivable - that Moodley does not have more information about his accomplices.

We also find it strange that Moodley managed to keep this secret from the police for so many years.

It is even more strange that he kept this secret from his own family because he claims he was afraid they would be killed.

If so, what makes him think they won't be killed now?

Moodley must simply come clean and tell the true story of Matthews' murder.

The Matthews family deserves to close this terrible chapter and the only person who can assist in this regard is Moodley.

We don't believe he deserves a retrial because his so-called "fresh evidence" (which he took to court this week) appears to be as ridden with untruths as his previous stories.

It is also not known at this stage if Moodley can prove the existence of the drug dealers he claims to have been his accomplices.

It is tragic that he's told so many lies since Leigh's murder.

Like the boy who cried "wolf".
