A woman was jailed for life today for stabbing to death her ex-husband after shackling him to the bed during a sex session.
Denise Lawrence believed her 37-year-old former husband Adrian Anson was guilty of sex offences – even though he had been cleared by a court – and killed him in an act of “revenge”.
Lawrence, 47, of Oak Court, Tongwynlais, south Wales, denied murdering Mr Anson in April this year, Cardiff Crown Court heard.
A jury of eight men and four women took almost 15 hours to find her guilty.
Mr Justice Richards, jailing Lawrence for life, told her the murder was “an act of great wickedness”.
He said: “It was a carefully planned and executed killing for which until now you have shown so far as the court is concerned no remorse.”
After the verdict, Jane Crowley QC, defending, said that while in custody Lawrence had been able to contemplate the effect of her actions and had indicated remorse and distress.
Prosecutor Greg Taylor QC previously told how in April, Lawrence stabbed Mr Anson a number of times – one of the stab wounds went through his heart and proved fatal. She had admitted manslaughter.
Mr Taylor told how Lawrence had left Mr Anson dying after he was tied up for “kinky sex” in his Cardiff home.
He said Mr Anson was naked and “shackled to the bed”,wearing a black mask.
Mr Taylor said Lawrence “massaged him, made love to him” and left the room to fetch some lager.
He said: “She took two knives, returned to the bedroom and she stabbed Adrian Anson four times.
“One of the wounds was fatal, penetrating the chest cavity.
“Denise decided to leave at that stage. Adrian Anson was dying and Mrs Lawrence knew it.
“He shouted to her and called for help. He was bleeding profusely from the chest.
“There was little panic on the part of Denise Lawrence. When Adrian was tied to the bed, she had to dress herself, prepare to leave.
“Before she went she turned the music up loud to cover his shouts for help.”
Mr Taylor said neighbours heard “bumps and bangs” on the night of the incident.
He said Lawrence then drove to her sister’s house and said: “I’ve done it. I’ve got rid of that piece of filth.”
Mr Taylor said Lawrence told how she had tied Mr Anson up for “kinky sex”. The police were later called.
The pair had met when Mr Anson fitted carpets for Lawrence at her former home in the Llanishen area of Cardiff.
They decided to wed in October 1991 and were married the following month after a “whirlwind romance”.
Mr Taylor told the jury that the marriage had initially “worked well“, even though Lawrence told her partner she was bisexual.
But after three years, Lawrence met another woman and told Mr Anson that she was in love with her and the marriage was over, Mr Taylor said.
The prosecutor said that relationship lasted for about five years.
Mr Taylor said that after Lawrence and Mr Anson no longer lived together, Lawrence heard of allegations that Mr Anson had committed offences of indecent assault and gross indecency.
But a jury at Newport Crown Court acquitted Mr Anson of those charges in 1997.
Mr Taylor said: “Denise Lawrence could not reconcile the jury’s verdict of not guilty with the allegations made.
“She began binge drinking spirits, brandy, vodka, wine and going to her doctor and receiving prescription pills.
“This went on for some time. Her GP treated her for depression, some obsessional tendencies, agoraphobia and heavy drinking.”
He said Lawrence was referred to an acute psychiatric team and added: “It was obviously a time of trauma.”
Mr Taylor said she referred to Mr Anson as “a piece of filth“. He added: “She could not understand the verdict.”
After the trial, Lawrence sought to re-establish contact with Mr Anson.
“She told people she would not have any peace until she found out the truth,” Mr Taylor said.
“The sequence shows a determined effort by Denise Lawrence to find Adrian Anson to entice him back to her.”
Mr Taylor said she wanted to take “revenge” for what Mr Anson had allegedly done.
He said that people around Lawrence could not stop her “evil plans“.
