A teenager stood by as her boyfriend knifed her father to death in a row over money, a court has heard.
Antiques dealer Antoni Robinson, 61, was stabbed 15 times as he slept in bed at his home in Old Colwyn, North Wales, Mold Crown Court heard.
Prosecutors said Gordon Harding, 20, launched the attack “supported and encouraged” by his girlfriend, the victim’s daughter, Ashleigh Robinson, 19.
Harding and Robinson, of Llanelian Road, Old Colwyn, are accused of murder with Sacha Roberts, 19, of Woodland Road West, Colwyn Bay, and a 16-year-old girl who cannot be identified because of her age. All four deny the charge.
Andrew Thomas QC, opening for the prosecution, said the attack happened in the early hours of July 7 last year when the four defendants gained access to Robinson’s home as he slept.
He told the jury of seven women and five men that Robinson suffered wounds to his face, neck and upper body, including four stab wounds to his back.
At least two knives were used, the prosecutor added, a ‘Commando’ style army knife with a 7in (17.8cm) blade and a kitchen knife with a 3in (7.6cm) blade.
Mr Thomas alleged the killing was the tragic result of a family dispute over money, jewellery and property.
He said Harding had admitted stabbing Robinson but that it had been in self defence. Mr Thomas told the court that Robinson “did not appear to have put up much of a struggle”.
He said: “It appears that Mr Robinson had not been able to fight back or to escape. We say Mr Robinson must have been completely overpowered by his attacker or attackers.”
