A feast for the eyes!

A jealous father-of-twelve who burned his 24-year-old lover to death after he discovered she'd been having an affair with his 18-year-old son, has been jailed for life.

Dailymail reports:

Ashley Williams, 49, put tape over the mouth of his 24-year-old girlfriend Julie Beattie and hit her with a hammer before dousing her in petrol.

She managed to stagger out of her home in flames like a ‘zombie' and gasp: ‘Ashley did this to me', before collapsing. She later died of horrific injuries.

Two children aged four and five witnessed the murder and became the youngest witnesses to give evidence at a murder trial.

Her sister Lucie Beattie described arriving at their south London home to see Williams put on his coat and walk out as Ms Beattie burned, screaming, behind him.

Mr.Williams carried out the attack in revenge because the mother of his four children was packing her bags to live with his son Ashley jnr from a previous marriage.

He claimed that he had thought he was involved in a 'water fight' and that she had been throwing the fuel at him - but he had no idea how she actually became ignited.

But he was convicted of murder at the Old Bailey by a jury of six men and six women.

He showed no emotion as the verdict was announced while the victim’s family wept and clutched each other’s hands. He was jailed for life and told he must serve minimum of 25 years before being considered for release.

Williams was married to Monica Williams and the couple had eight children together before they divorced in 1999.

He then started a relationship with Linda Beattie, who had three children, including Julie, before he moved on to Julie.

Ms Beattie was aged only 16 when she gave birth to their first child in 2009.

Ashley Jnr, 18, moved into the flat in Walworth, in September 2012 and began a sexual relationship with his father's girlfriend four or five months later.

When Williams found out, he banned his son from having anything to do with Ms Beattie and tried to exile him from London. He threatened to ‘break every bone in his body’ if he refused to leave town.

On July 18 Ms Beattie and Ashley Jnr travelled to Birmingham together. The couple had come back to London on the day of her murder, the same day Williams had sent a number of texts, begging Ms Beattie for forgiveness. In one message he said:

I tried over and over with you Julie. I wish you nothing but the best... I’ll always love you, I just showed it too late, please forgive me Julie.

He also sent his children bizarre messages blaming them for the break up of the relationship. In one he stated:

When my life is done..mark these words of your father, my curse will begin.

Williams, of Walworth, who had denied the charge, was convicted of murder.
