Cannabis user jailed for 24 years for stabbing his grandmother to death 50 times in bed ‘because she got on his nerves’ and then trying to kill nine-year-old

A cannabis user who murdered his 84-year-old grandmother, stabbing her 50 times as she lay in her bed, and then attempted to kill a nine-year-old boy has been sentenced to life in prison. A judge today told Nathaniel Flynn, 27, that he will face at least 24 years behind bars as he passed a life sentence at Bradford Crown Court. Mr Justice Keith said the most likely explanation for why he killed retired teacher Louisa Denby was that 'she just got on your nerves'. Flynn admitted killing Ms Denby at their home in Shipley, West Yorkshire, in July, and stabbing Jason D’Arcy in a nearby skate park later the same day. The court heard that Jason suffered a shallow wound to his chest and a much more serious injury to his arm as he tried to defend himself. The judge heard that three psychiatrists found he had no diagnosable mental illness but said he had been influenced by his heavy, 'entrenched' use of cannabis and other drugs. Speaking after Flynn pleaded guilty earlier this month, police officers said they had no idea what drove Flynn to commit the 'brutal and frenzied' attacks.
