Two "Judas-like" teenage sisters were yesterday handed jail sentences of 18 and 22 years for the brutal knife murder of their father.
Retired antiques dealer Antoni Robinson (61) from Old Colwyn, north Wales, was stabbed 15 times as his daughters and their boyfriends tried to get their hands on the contents of his safe.
Ashleigh Robinson (19) and her 16-year-old sister Holly "supported and encouraged" the frenzied late-night attack on Mr Robinson in July of last year, Mold Crown Court heard.
The daughters were convicted of murder alongside boyfriends Gordon Harding (20) and Sacha Roberts (19).
The four had hatched a plot to sneak into Mr Robinson's bedroom to find out what cash and jewellery he had in his safe.
Harding repeatedly knifed Mr Robinson, who was asleep in bed, using a knife handed to him by Roberts as the girls stood by, the jury heard.
All four were jailed yesterday by Mr Justice Griffith Williams, who labelled their crime "Judas-like and wicked".
Ashleigh Robinson and Harding, of Llanelian Road, Old Colwyn, were told they must serve at least 22 years.
Holly Robinson, who lived with Roberts in Colwyn Bay, sobbed as she was ordered to be detained for at least 18 years. Roberts was ordered to serve 20 years. The judge told them: "Antoni Robinson was murdered in his own bedroom, stabbed 15 times. You were after the jewellery.
"It is to be hoped that in his dying moments he was at least spared the awful realisation that his own two daughters were party to his murder.
"Two daughters who were scornful of him. Two daughters who had appealed for his kindness. Two daughters who, Judas-like, wormed their way back into his affections."
The sisters and their boyfriends then plotted with the girls' mother, Joanne Barr, to give a false account of what happened to police.
Barr, her daughters and Roberts pleaded guilty to conspiracy to pervert the course of justice.
Harding was found guilty of the same charge.
Barr was labelled "wicked" by the judge as he jailed her for four years. He said: "You were not in the least concerned about the murder of a man who loved you."
