A paranoid cannabis addict who subjected a frail 93-year-old man to a horrific 28-hour ordeal has been sentenced to life in prison for murder. Samuel Field, 40, punched, stamped on, and strangled Martin Glynn at his home in Desborough, Northamptonshire, on September 19, 2024, while under the influence of paranoid delusions.
The Attack
Field, who had known Mr Glynn for nearly two decades and received £200 weekly from him, became enraged by a conspiracy theory that Mr Glynn had given Field's house key to an Irish Traveller. Believing he had been betrayed, Field brutally interrogated his victim for hours, demanding a confession to something that existed only in his imagination.
Prosecutor Adrian Langdale KC described the assault as 'effectively torturing and interrogating' the elderly man. Mr Glynn suffered brain bleeds, a broken neck, and severe bruising and swelling across his body and face. Harrowing footage from Field's home showed Mr Glynn's foot motionless on the living room floor for many hours after the attack, while Field went about his day as if nothing had happened, even making voice recordings claiming 'everyone is in for him'.
Aftermath and Death
After over a day of failing to extract a confession, Field called an ambulance. Mr Glynn was found 'unceremoniously dumped' in a shower tray. He died from pneumonia at Kettering General Hospital on December 26, 2024, three months after the attack. Despite his deteriorating condition from brain injuries, Mr Glynn used his last words to name Field as his killer and told detectives that Field had blackmailed him into handing over thousands of pounds.
Trial and Sentencing
Field denied murder, claiming 'it's lies,' but was found guilty by a jury after less than four hours of deliberation. He was sentenced to life imprisonment with a minimum term of 22 years at Northampton Crown Court on May 29. During the 11-day trial, Field sacked his legal team and represented himself. He admitted to punching Mr Glynn four times in the head, describing him as a 'very close and dear friend,' but claimed he never intended to kill him.
Sentencing, Mr Justice Eyre stated: 'It goes without saying that Martin Glynn was in no position to put up any resistance to this attack. You knew he was at your mercy and that did not stop you.' The judge noted that Field continued using cannabis despite knowing it made him a danger to others. Field had previous convictions for punching a three-year-old and a one-year-old in the head in 2007 and 2008, which the prosecutor called 'chilling echoes' of the murder.
Victim Impact
In a victim impact statement, Mr Glynn's relatives in Ireland described him as a 'quiet, soft-spoken man' and said: 'The impact of losing Martin has been very distressing for our family. Such evil bestowed on such a kind, gentle, caring, loving, giving, good humoured, inoffensive soul.' Detective Sergeant Megan Scotney of the East Midlands special operations unit expressed condolences, adding: 'Mr Glynn was a kind, gentle, loyal man, stripped of his independence by the cruel and calculated actions of Samuel Field.'
