  Mr. Peter Barnes, on behalf of the Director of Public Prosecutions, alleged that on the night of November 22, Jones struck his wife with a hatchet. Mrs. Jones was taken to hospital with three head wounds and died two days later.

Happy family
  "It is a tragic case because until this fatal day they were a perfectly normal, happy family." he said.
  Police-constable John Green, who went to answer the call with Detective-sergeant Gwilym Evans, described the time he spent alone with Jones. He said that Jones, was continually wringing his hands and burying his face in them. In a disjointed conversation he told the constable that he had not slept for about "two or three weeks"
  Later Jones told the officer. "It started last summer. She could not sleep and then I got it."
  Jones was committed for trial at the next assizes. He pleaded not guilty and reserved his defence

TEACHER WHO KILLED WIFE FOUND INSANE
  For an hour-and-a-half, at Glamorgan Assizes in Cardiff yesterday, the jury listened to the tragic story of a devoted father and husband who killed his wife with a hatchet.
  The husband, a 48-year-old schoolmaster, Iorwerth Jones, of Princes - avenue, Cardiff, was found guilty of the murder of 43-year old Agnes Elizabeth Jones, but insane.
  Jones, who used to teach at Metal-street School, Cardiff, was ordered to be kept in custody as a Broadmoor patient until her Majesty's pleasure be known. Mr. Roderic Bowen. Q.C., M.P., who appeared with Mr. Norman Francis for the prosecution, said Jones and his wife had three children, the eldest of whom they had adopted. It was a perfectly happy household.

Wife's health
  After the birth of her last child, Mrs. Jones's mental health gave grounds for anxiety, and she was to have entered Whitchurch Hospital as a voluntary patient on November 23.
  In the early hours of that day, Jones attacked his wife with a hatchet while she was in bed. She died two days later. Jones told Police-constable J. P. Wheatley, he had not been able to sleep for about two or three months.
  Detective-inspector John Thomas, who had known Jones for years, said he was a devoted husband, father and churchgoer.
  Called by the defence, which was conducted by Mr. Philip Wien, Dr. J. P. Spillane said he found Jones to be suffering from melancholia, a disease of the mind. On the night in question, he did not know fully the nature and quality of the act he was doing.
