I wonder how many people believe Sion Jenkins is innocent? It seems to me we have our very own OJ Simpson case. We can't prove he is guilty but what other possible explanation can there be for Billie-Jo's death?

What I can't understand is why he was on television proclaiming his innocence?

If it were me in his position I would want to grieve quietly, privately at such an awful slight on my character. I would be devastated to think friends and family could think me capable of such a crime.

I would be crushed, not least because of the grisly death of a much-loved daughter, but because of the terrible shame of being thought a suspect.

In terms of the verdict, how is it possible the jury in the final trial were not privy to key facts such as new forensic tests which have found blood splatters on Jenkins' clothing containing fragments of her bone, throwing into doubt Jenkins' testimony the splashes were caused by the girl's final struggle for breath?

Or that he had a record of violent outbursts and was a bully to his first wife, often lashing out at his children?

Accusations he categorically denied in his television interview with Sir Trevor Macdonald.

The Tonight programme ended with the admition by Jenkins' daughters that his denials of violence in the home were lies.

And that Sion had had an affair with a 17-year-old Billie-Jo lookalike? Just listening to his own explanation of events left me feeling uneasy.

How can late evidence not be heard? Surely this can't be right?

Reading the original judgement in the first court of appeal in December 1999 it seems clear the key to this case is the evidence of his other daughters which was not used in the trials.

His first wife was quoted revealing a conversation with one of her daughters after the day of the murder in which one daughter admitted knowing her father had had a screaming row with Billie-Jo earlier on the day of the murder.

And on the day in question, she had been told to wait by the car and had tried three times to go back into the house but was refused entry on each occasion by her father.

When waiting by the MG, she also saw her father come running down the stairs and say to her and her sister to get in the car but neither she nor her sister knew why.

The same daughter said on the day of the murder her father had said: "We'll be alright. We were together weren't we?"

The case for revising the double jeopardy law has never been so strong.
