The Cornelius Dennehy Murder Trial

Next week ‘Ceart Agus Coir’ (an Irish & English language series that charts the history of the death penalty in Ireland) looks into the case of the death of Millstreet man Cornelius Dennehy in 1938. (Feb 4th TG4 10.15pm.). The below is a summary of the programme:

BY MICHAEL TRACEY on the Laois Nationalist
IT was a tale of murder most foul that gripped the country and centred around one Laois man.

In January 1939, James Dermot Smyth from the Rushes, Wolfhill, was executed by hanging after he was convicted of the murder of a Cork butter buyer. The victim, Cornelius Dennehy, was found dead in his car near The Swan having been shot in the head at close range.

The pair were well known to each other and Smyth had even described Dennehy as his “best friend”, so the crime became known as the “best friend murder”. The grisly incident is the subject of an episode of TG4’s Ceart agus Cóir series on the death penalty in Ireland.

The programme, featuring research of newspaper articles and court and prison archive, as well as other public records, will be shown on 4 February.

At the time, Smyth was 33 and married with a toddler daughter. He lived in a cottage and farmed 130 acres owned by a cousin. He had attempted the buy the farm but the deal had fallen through despite hefty solicitors’ fees.

Smyth was said to be fond of drink and was well known around the pubs of the area. His wife, Mary, kept rigid control over the purse strings, however, leading Smyth to habitually borrow money if he wanted drink.

The victim, 34-year-old Cornelius Dennehy, from Millstreet, Co Cork, was well-liked during the five years he had lived in De Vesci Terrace, Abbeyleix, where he was known as “the butter man”.

Dennehy travelled regularly to fairs in the midlands and his Ford V8 car was a familiar sight on local roads. It was widely known, including to Smyth, that he carried large sums of money with him on his travels.

On the morning of 17 August, he set out for Tullow where he was due, as usual, to meet a dozen or so butter sellers.

Dennehy’s route from Abbeyleix to Tullow would have taken him through The Swan Crossroads, then on to Doonane Crossroads, Newtown Cross and Tullow.

John Doyle, who worked at Swan Fireclay factory at The Swan crossroads, about a mile from where the shooting took place, said that at about 10.20am, he saw Dennehy driving slowly past in his Ford car. They saluted each other. Doyle was the last person to have reported seeing Dennehy alive.

The Ford car was seen parked awkwardly on a lonely road near The Swan. Passers-by ignored it as there appeared to be no one in the car. That evening, Patrick Kelly, another clay factory worker, passed the car at about 8pm and looked in the passenger rear door but did not see anybody. He went around and looked through the window of the driver’s door and saw a man in a crouched position. It was only when he opened the car and put his hand on the man’s leg to shake him that he realised he was dead.

Although Cornelius Dennehy had been shot at close range there was no significant singeing and there was no gun at the scene. There were signs that the murderer had tried to set the car on fire.

The petrol cap had been removed and there was a bloodstained, burnt match at the scene. Robbery was the obvious motive as Dennehy’s wallet was missing.

His injuries were described as horrific. He had been shot on the right side of the head.

The blast had nearly taken it entirely off his shoulders. According to the state pathologist, Dr John McGrath, the base of the skull was “extremely fractured” and remnants of the brain were splattered across the front seat. Dr McGrath said the fatal shot was fired by a single-barrelled gun.

Fifty gardaí were involved in the case and the investigation drew widespread media coverage. Smyth, at one stage, was said to have been seen in the background in one of the press photos taken at the scene.

During the investigation, gardaí interviewed Smyth who said he had been on the road to visit a friend on the day before Dennehy was killed.

However, it appears Smyth’s wife told gardaí that the day after the murder she had to give her husband a clean collar because he had blood on the one he was wearing.

When gardaí returned to Smyth’s house, Smyth went over to the sergeant’s car and remarked: “Wasn’t I an idiot to be at The Swan on Thursday with blood on my neck?” He showed the sergeant small cuts on his arms that he said he got them cutting scallops.

On 25 August there was a breakthrough in the case as the suspected murder weapon was found in a hedge a mile away from the killing.

Evidence would show that it had been recently fired. The gun was identified as belonging to the Fitzpatricks who had loaned it to Smyth three weeks before the killing. Smyth said he had wanted to shoot a cat.

Two days later, Smyth was cautioned and gave a sworn statement.

The day before the killing, witnesses saw Smyth at the place, known as “Patsy O’Neill’s gate”, where the car and body of Cornelius Dennehy would be found the next day.

Smyth said that on the morning of the murder he cycled into Crettyard, stopping at two pubs for a drink before going home at lunch time. He added he had not carried or used a shotgun for about 14 or 15 years.

When he was searched, a wallet containing a bundle of six £5 bank notes was found on him. These would be linked to Dennehy in the prosecution’s case.

The trial opened on 21 November 1938 and lasted for eight days. This was one of the longest murder trials in Irish legal history to that point.

It was referred to as the trial of the year, with over 100 witnesses called. After Dennehy’s death, Dermot Smyth described him as his “best friend”.

This assertion appeared at odds with Smyth’s statement that he had only gone for drinks with him a few times.

Smyth admitted in his statement that he was on the road where Dennehy was killed the day before the murder.

A witness, John Poole, who met Smyth on the day before the murder, said he saw what he took to be a gun, with a canvas bag, in the ditch beside Smyth. Smyth argued it was a wooden lath in the canvas bag, which had resembled a gun parcel.

The motive put forward by the prosecution for the murder of Cornelius Dennehy was robbery. A key issue, therefore, was whether Smyth was struggling financially.

The prosecution highlighted that Smyth borrowed money a number of times in the run-up to the killing. On the day of the murder, Smyth was alleged to have spent around £41.

The prosecution outlined payments made by Smyth in the days after the murder. He sent £24 in notes to his cousin in Dublin to clear the debt that he owed on some farm stock. The amounts mentioned compared very closely with the amount thought to be missing from Dennehy.

Defence counsel argued that the defendant was a man of substance but that the prosecution was trying to portray him as someone who “led a strange and peculiar life”.

The prosecution put forward a number of witnesses who claimed that Smyth was on the stretch of road where Dennehy was killed at about the time he was killed.

The evidence of two local children was important. They lived near the scene of the killing. The pair said they saw a man cycling in the direction of The Swan at 8am. Sometime around 10.30am they heard a car up the road brake suddenly and make a screeching sound. Five minutes later they heard what they thought was a shot.

They looked up the road and saw a car parked facing a gate and a man taking a bicycle from the ditch and cycle away in the direction of The Swan. As the man passed them, they noticed a parcel attached to the cross bar and that his hands were red. The children subsequently picked Smyth out of a police line-up.

The defence said that the children were imaginative and impressionable. The defence also argued that the children identified Smyth because he was the only person they had known in the identification parade after being prompted by gardaí.

The defence put forward their own witnesses to try to prove that Smyth was in another place at the time of the killing.

They added that Smyth thought the gun was in his house. It was argued by the defence that the gun may have been stolen by some tinkers who were around the house in the previous couple of weeks.

Judge O’Byrne, in his summing up, concluded that it was reasonable to assume that this was the murder weapon. He said it was also “most unusual to hear of tinkers stealing or being in the possession of firearms”.

The driver’s door of the car had some fingerprints in blood. Inspector Harry McNamara, a fingerprint expert, went into the dock and sat beside Dermot Smyth. He examined fingers on the defendant’s right hand closely and said he was satisfied beyond doubt that a print on the car had been made by Smyth’s right ring finger.

Of the six notes found on Smyth when he was arrested, four were bloodstained, however, Smyth said in evidence that he had cut his arms and hands. Smyth was also found in possession of sequenced bank notes matching notes issued to Dennehy at a bank in Midleton.

In evidence, Smyth answered question after question without hesitation over three days. Smyth said Dennehy had given him money; a fact which had not been in his original statement.

The defence argued the case had been prejudiced by media intrusion.

PJ McEnery said: “The newspapers have been blazoned with the facts, details and circumstances of the case from the state point of view and I will take the opportunity of saying that, by reason of one-sided publicity, Dermot Smyth has already been convicted in the public mind”.

The huge public interest in the trial continued right to the day of the verdict, which saw remarkable scenes even for the courthouse at Green Street, Dublin, the scene of many famous cases, with gardaí closing off the street due to the size of the crowd.

In summing up, the judge said the evidence was circumstantial but there were a number of inconsistencies in the defence’s case. After the jury returned a guilty verdict, Smyth was said to have paled visibly.

When he was sentenced, Dermot Smyth replied: “I am condemned. My next judge shall be my creator. He will prove me an innocent man and I hope and pray that the murderer of Cornelius Dennehy will be got after, to clear my name, so that no man can ever say of my child that her father was a murderer.”

This was not to be the case. Smyth unsuccessfully appealed and a widespread petition that was presented to the government also failed to earn him a reprieve. He was executed at Mountjoy Prison on 7 January, 1939.

The Smyth episode of Ceart agus Cóir will be broadcast on 4 February at 10.15pm.


Millstreet Mother’s Claim. Abbeyleix Crime recalled in CORK CIRCUIT COURT


AT Cork Circuit Court, on Friday of last week, before Judge J. E. O’Connor, a claim for £300 compensation was made under the Workmen ‘s Compensation Acts on behalf of Timothy Dennehy, Killarney Road, Millstreet, for Norah Dennehy, widowed , mother of Cornelius Dennehy, butter buyer, who was murdered at Doonane, Abbeyleix, on August 17th last. The claim was in respect of the death of Cornelius Dennehy and the respondents were the Irish Butter Exporters’ Association, of 34 Dunnar Street, by which ho was employed. It will be remembered that Dermot Smyth, a small farmer , of Abbeyleix , was convicted of the crime and was hanged on January 12 last. Mr  Michael Binchy, S.C. and M. Frank Neville (instructed my Messrs. C. W. Ashe and Co., solicitors , Macroom) appeared for the applicant and Mr. Michael O’Driscoll (instructed b y Mr. James McAuliffe, solicitor) for the respondents. STAGES OF EMPLOYMENT. Mr . Binchy said that deceased entered the employment of the respondents when he was a boy of fourteen years of age and had been with them up to the day of his death. Mr. Shanahan , who was a director of the respondent company, took Dennehy from school . The deceased was the son of a labourer and was one of a family of shr (?) children . In 1922  when he was fourteen years old, Mr. Shanahan took him into the business to train him. At first the boy received 30s. weekly all round, both in and out of season. Later on there was another arrangement, in which he received 10s. a day in the season and 30s weekly out of season. The third stage in the course of his employment was reached in the year 1933 when he was transferred by His employers to Maryboro’ and was put in charge of the business there. Then the arrangement as to paying. him changed. He was still controlled in every way by the Arm, but instead of being paid so much a week, he was paid percentage on commission on what butter he bought. In addition, he was paid his travelling expenses by the firm , and any other expenses incurred, such as casual help under that arrangement he received cheques Several times weekly for the purpose of buying butter and roburne?. a weekly account of his outgoings to his employers, crediting himself with his ‘board and lodging, etc. , and returning the balance . The final stage in his employment conditions . .was reached when the deceased was told to remove from Maryboro’, to Abbeyleix , and make his head quarters there. From there the deceased attended markets in a great many neighbouring towns and villages.
LETTERS OF INSTRUCTION. Counsel then read a list of the markets attended by deceased from day to day. Continuing, he said the new Arrangement as to payment, in force at the time of the death of the deceased, was due farthing per lb. on butter bought, plus his expenses. He would show that the deceased had no discretion himself but was controlled absolutely from Cork. I counsel read a letter of April 17 , 1936, sent to him by the respondents when he was in Abbeyleix and al/o a telegram of May 14, 1938 . ‘ In addition, counsel said he had in court a bundle of original betters of instruction Dennehy had got from his employers, and the tenor of them all was consistent with the assumption that the deceased was controlled in every way by the respondents. The deceased steadily sent money to his home, went, on counsel , and shortly before his death had sent a sum of £20 to his mother. Sometimes he had sent her £40 . In addition to those cash payments, the deceased, when he went home, paid all the bills on the homestead, in fact, when last at home, a short time before his death, he had the house done up at his own expense. It was part of his business as a butter buver to carry about with him large sum of money which he received from his employers for the purpose of his work – He was murdered on August 17 by one Dermot Smyth— that was – ‘ fitted. On the Saturday before he ‘Wth he received from his employer a cheque for £200, which he cashed in a bank in Abbeyleix. Between that and the day on which he was murdered he had received another £200 cheque, which was found uncashed after his death. When he got, those cheques he usually cashed them. paid out whatever he wanted for personal expenses, and then went around to the various markets with a bundle of notes out of which he paid cash to the customers who sold him their butter.
IN BLACK WALLET. He usually carried large bundle of notes in a black wallet, and while attending a market would have the wallet and a quantity of silver and corroers on a table paying out for the butter, according to weight . That was his practice for a considerable time before his death, and the practice was well-known around the countryside, among others, to Dermot Smyth . A week before his death, at a market in Carlow , the deceased carried out that procedure. He had given a drive in his motor ear to a man named White, and White would tell, the Court about the black wallet . While White was there with Dennehy, Dermot Smyth came up and asked Dennehy to give him a lift home, which he did. It was important to note that Smyth went there not to buy butter at all , but to see what was going on, and he was quite familiar with the methods employed by the deceased, and that Dennehy was going around  the towns from market to  market with this montey. In fact, one p1ace  witnessed Dennehy held a market cast a  house or a brother of Smyth’s there tho same procedure was ^otlowod. It was aS jpitt ed, ^aid Cfouhae^’ f WShat Dennehy: was; murdered and he hoped to produce ample evidence to his lordship that he was  killed in wag ……..  he was paid his railway fires from  place to place by the respondents, and it was in that way the car was bought. It might be argued deceased used the car as a hackney car, because he  had it registered as such, but he hoped to prove the car was used -for his business and the money he was, allowed by the respondents for railway fares was James White said ihe was employed by applied towards its up keep, Edward Morrissey, merchant , Abbeyleix , and knew the deceased , who called at his employer ‘ s place . He had seen Dermot Smyth when Dennehy was buying butter at the house of Smyth’ s brother at Wolfhill

7 thoughts on “The Cornelius Dennehy Murder Trial”

  1. Cornelius Dennehy was originally from Aunagloor (halfway from Millstreet to Ballydaly). He had two brothers Thade and Andy (who both emigrated to America) and a sister Jane.
    The car he was murdered in was brought back to Millstreet by his brother Thade and this was the taxi in Millstreet for years. The registration plate was “ZB 1129”.
    There are two pictures of his funeral in the “Picture Millstreet” book which was published by Seán Radley some years ago.

    1. Cornelius Dennehy was originally from Aunagloor,Millstreet. He was son of
      the late Peter and Hanora Dennehy. He was one of a family of six, four boys Daniel,Thade,Andy and Cornelius and two girls Ellen and Jane. Daniel married in the early 1940’s and moved to Mallow,he lived there up to the time of his death,he had four children Nora,Peter,Denis,Kathleen.Jane married a local
      Millstreet man Paddy Kelleher they moved to Enniskeane where they resided up
      to their death, they had two sons Jerry and Peter and a daughter Kathleen who died young.Thade Married and lived in Ballydaly, while Andy and Ellen remained in the home place in Aunagloor.Around 1960 Thade and his wife Hannah,Andy and Ellen all decided to emigrate to America.On retirement they returned Thade and Hannah settled in Killarney and lived their up to their death. Andy and Ellen settled in Ballineen/Enniskeane and lived their until they died.

      1. Peter,
        I posted another version of Cornelius Dennehy’s family. My family believed he was the son of Jane and Cornelius Dennehy, and the brother of Norah. However based on his age 34 in 1938, it is unlikely he was the son of Cornelius and Jane who were married in Millstreet on February 9, 1867. I think your account is probably more accurate. Much of our belief is because the pictures of the funeral in the Millstreet book, which references Jane as his Mother, and a family story about a relative who was murdered in Ireland in the late 1930’s.

        My great grandmother Margaret, was daughter of Cornelius and Jane Dennehy, and the sister of Norah, Jane, John, Mary, Timothy, Hannah, and Julia Dennehy. There may be two other brothers who we cannot account for. I am assuming our Norah, and your Hanora, are the same person.

        Are you related to Kathleen Collins, Denis Dennehy, and Norah Toomey(spelling?) who I met on my visit to Ireland in 1999. I met with Sean Radley at that time too. If possible I would like to communicate with you directly to compare information. I sent an email to Sean and the other administrators at <email>. If you would like to share more information, you can contact them. I told them to share my email with you, if you requested it.


  2. A few points to correct and add to the comment by Anonymous.
    Cornelius (“Con”) had THREE brothers not two, Dan, Thade and Andy. Dan was the eldest and in fact was the one who identified Con’s body. Whilst the other two brothers did emigrate to the States they both returned in later life and saw out their days around Millstreet. Neither had any children. Dan married and moved to TwoPotHouse, Mallow, where he had four children, Nora, Peter, Kathleen and Denis. Jane stayed in Millstreet and has two surviving sons, Gerry and Peter.

  3. just watched the programme and thought it was indeed a great piece of irish history. the two children who gave evidence in this trial were in fact my grandmother and uncle…there had been great talk of this story over the years.

  4. I would like to offer another version of Cornelius Dennehy’s family which differs from Anonymous, Peter, and Tom. He was the son of Cornelius and Jane Dennehy. Jane is listed as his Mother in the funeral pictures in Sean Radley’s Millstreet book. Sean told me it was my family. According to our records we believe there were 10 children, 4 boys and 6 girls. Cornelius, Nora, Jane, John, Mary, Timothy, Margaret (my great grandmother), and twins Hannah and Julia. We do not know who the last son was, but based this story it was probably Andrew. We know and can verify Margaret, Jane, and Hannah emigrated to the United States and died here. Norah came to the US and returned. I am researching my Dennehy roots and would like to connect directly with others who believe they are from the same family.

    1. His parents were Peter and Norah (Hanorah).

      I’ve added to the article above a report from a Circuit Court compensation claim by his mother Norah from July 1939.

      also added are links to his death and birth (1908) registrations.
