Robinson sisters, Colwyn Bay, North Wales
At 1 a.m. in July 2010, Ashleigh Robinson’s mother, Joanne Barr, received a text which read: “Things happened, he is no more. Sorry mum xxx.” The 19-year-old sent the message as her father, Antoni, 61, lay dying. She and her sister, Holly, 16, had enlisted the help of their boyfriends, Gordon Harding, 20, and Sacha Roberts, 19, to murder him. They crept into Antoni’s bedroom, and Gordon stabbed him 15 times with a kitchen knife and a seven-inch commando-style blade as the sisters watched. All four were found guilty of murder.
