Mentally-ill father who thought his son was the devil knifed toddler and his wife to death

A mentally ill father stabbed his two-year-old son and wife to death because he thought the boy was the devil. David Wyn Jones, 42, of Tremadog, Gwynedd, a former insurance salesman, was sent to a secure psychiatric unit by a judge at Caernarfon crown court. He had admitted their manslaughter on the grounds of diminished responsibility. Sending him to Ty Llywelyn medium secure unit at Llanfairfechan, Judge Merfyn Hughes QC told Jones : 'For many years your wife cared for you both in good and more difficult times. 'It’s clear from the evidence before me she died in a desperate but ultimately unsuccessful attempt to save the life of her child. 'William was only two, an innocent and defenceless victim. What you did to both of them was dreadful and terrifying. 'It’s to be hoped at least William was too young to fully understand the threat he was under until it was too late.'
