Passionate love letters from a mum-of-three to her new boyfriend reveal a plot to get rid of her former lover, a murder trial jury was told.

Tracey Cameron told Graham Haylett "let it end tomorrow night", it is alleged.

Prosecutor James Goss QC told Leeds Crown Court the letter was written on August 7, 1996, four days before Cameron's former lover, Leonard Fulbirg, disappeared.

Mr Fulbirg, 49, was never seen again after arranging to meet Cameron at McDonalds in Rooley Lane, Bradford, on Sunday, August 11, 1996, Mr Goss told the jury.

Cameron, of Dunsford Avenue, Bierley, and Haylett, both 40, deny murdering Mr Fulbirg whose dismembered remains were found on moorland above Keighley on March 2, 1997.

Some of the bones of a human torso were discovered near a lay-by on the A6033 at Cock Hill, above Oxenhope.

Mr Fulbirg was identified in 2003 by DNA profiling. His head, arms and legs have never been found.

Mr Goss said Mr Fulbirg, who was living with his brother, Robert, in Coldbeck Drive, Buttershaw, was obsessed with Cameron. They had a child together in 1994 and had lived in Parkwood Rise, Keighley.

Mr Goss said Mr Fulbirg was a womaniser who had been married four times and fathered at least 12 children.

Mr Goss described him as a paedophile with a bad criminal record for dishonesty and violence.

While he was on remand in prison from February to August 1, 1996, Cameron became besotted with Haylett and they began a passionate affair.

But Mr Fulbirg was still passionate about Cameron, Mr Goss said and he presented an obvious obstacle to the new lovers.

The Crown's case is that the pair decided to solve the problem by killing Mr Fulbirg. He told the jury: "The evidence against Tracey Cameron and Graham Haylett of being directly involved in the disappearance and killing of Leonard Fulbirg is comprehensive and compelling."

The jury heard letters read out from Cameron to Mr Fulbirg while he was in jail in which she expresses her undying love.

But she also began writing to Haylett, who was then living at Lansdale Court, Holme Wood, Bradford.

In the letters to Haylett, Cameron says: "We will really have to be careful." She continues: "I am obsessed with you. You're stuck with me, you're mine."

In another letter Cameron states: "We need to start with a clear card." In the letter of August 7, 1996, she says: "It will be over soon and we can come home to start a proper family life."

She adds: "We have to be focused on why we are doing this. Let it end tomorrow night."

Mr Goss said the letter was written while Cameron was staying at a women's refuge. She had told social workers she wanted to get away from her home address before Mr Fulbirg was released from prison.

Cameron spent an evening with Mr Fulbirg in Keighley on August 8 and Fulbirg told others that they had sex.

Three days later she arranged to meet him at McDonalds but claimed she did not make it to the date.

Mr Goss said that Cameron told a woman at the refuge that the "paedophile she had fled from" had been beaten up and his body burnt and dumped on the moors.

Cameron allegedly told another refuge resident that she was going to meet the paedophile she wanted to be rid of, get him drugged then chop him up and feed him to the pigs.

She boasted the following day about having drugged his drink, tricked him into going to a flat to have sex and then having him killed.

Haylett, of Wilson Wood Street, Batley, also denies attempting to pervert the course of justice between April and July last year.

The trial, expected to last six weeks, continues.
