American Man Found Not Guilty by Reason of Insanity in Father’s Hotel Killing
A jury in Ireland has found 31-year-old Henry McGowan not guilty of murder by reason of insanity in the death of his father, 66-year-old John McGowan, at a luxury hotel in November 2024. The tragic case highlights the devastating impact of untreated mental illness and the agonizing choices families face when a loved one is in crisis.
The court heard that McGowan, from Brooklyn, New York, killed his father at Ballyfin Demesne, a five-star hotel in County Laois, on November 12, 2024, while experiencing a psychotic episode. Both the defense and prosecution agreed that McGowan was suffering from schizoaffective disorder at the time of the killing.
The events leading up to the death unfolded after McGowan experienced a relapse of his mental illness during a trip to Europe. He arrived in Dublin on November 11th, claiming he ran from Dublin Airport to the city center. Seeking help, he went to the Mater Hospital the following day, where he was prescribed medication. However, he reportedly did not disclose details of a previous mental health incident from 2022 to the doctors.
Concerned for his son’s well-being, John McGowan traveled from the United States on what was described as a “mission of mercy” to bring Henry home. The situation took a horrific turn just hours after the father and son reunited at the Mater Hospital. According to testimony, Henry McGowan, in the throes of a psychotic episode, killed his father. There was no prior history of violence between the two men.
Prior to the fatal encounter, McGowan had disposed of his belongings, including his passport, at the airport. The father and son spent the night at Ballyfin Demesne while awaiting an emergency passport. A taxi driver reportedly overheard John McGowan pleading with his son, asking him to promise he wouldn’t run away that night. An agreement was made for Henry to take his medication after dinner, but when he was seen walking naked around the pool area, his father led him to a changing cubicle.
Staff later discovered John McGowan in a pool of blood in the changing cubicle and pronounced him dead. Henry McGowan was found sitting in the library and subsequently provided a detailed account of the killing to authorities. He stated he believed his father was yelling at him and forcing medication, and claimed he was acting on instructions from God. He described strangling his father and expressed shock at how long it took to end his life, adding that he told his father he would always love him as his father took his last breath.
Psychiatric evaluations confirmed McGowan’s mental state. Dr. Stephen Monks testified that McGowan believed his father had been replaced by an “evil imposter” and felt ordained by God to kill him. Dr. Monks explained that John McGowan had become “incorporated into his son’s psychotic world” at the hotel. The expert also noted McGowan’s impulsive behavior leading up to the tragedy, including purchasing a “conspicuous pink coat” in Harrods and renting a Lamborghini in Paris.
The court also heard details of a previous incident in 2022, where McGowan was detained in a psychiatric hospital after attempting to seize an infant on a flight to Paris, believing he needed to sacrifice a child to save the plane. He had also expressed delusional beliefs about his father during that earlier episode. Family members first noticed a relapse in August 2024 when McGowan requested $60,000 from his sister. His mother accompanied him to Italy in October, describing him as “very manic.”
Prosecution expert Gautam Gulati affirmed McGowan was in an abnormal mental state and experiencing an acute psychotic episode. The McGowan family is described as wealthy, with John McGowan a former Wall Street trader and Henry McGowan having earned $4.5 million from his last job before quitting in October 2024.
During closing arguments, Senior Counsel Brendan Grehan acknowledged the tragic nature of the case, stating that those closest to individuals experiencing active mental illness are often the most at risk. He emphasized the tragedy of John McGowan’s death while attempting to help his son. Defense counsel Michael Bowman argued that McGowan’s behavior had been increasingly erratic before arriving in Ireland and that his father had prioritized his son’s mental health over his own safety.
Mr. Justice Paul McDermott underscored that the case revolved entirely around mental health. He informed the court that McGowan is currently receiving treatment at the Central Mental Hospital and will continue to do so. The judge thanked the jury for their service in a difficult case and excused them from jury duty for five years. He expressed his sympathy to the McGowan family, commending their “great dignity and courage” and their dedication to doing what was right.
The case is scheduled to return to court on February 20th for a hearing regarding McGowan’s proposed treatment program.
