A man who killed an 83-year-old great-grandmother when he repeatedly ran over her with his van has been jailed for 13 months. Beryl Howard suffered 'unsurvivable injuries' in the 'sudden and brutal' incident in Street, Somerset, in 2023, her family said.Cannabis user Reece McKinven, 31, was jailed at Taunton Crown Court on Tuesday and banned from driving for two-and-a-half years after admitting causing death by careless driving.Ms Howard's daughter, Sharon Perry, said her family would 'never get over what happened' and they were haunted by 'thinking of the pain and terror she must have felt'.The 83-year-old had been walking behind McKiven's Transit van as he was trying to reverse into a parking space in Green Lane Avenue at about 17:20 GMT on 16 March 2023. McKiven previously told the court he had not seen Ms Howard when his vehicle struck her and he was not aware she was underneath his van as he then tried to reverse four times.As Ms Howard lay severely injured on the ground, members of the public who had seen what happened sought to comfort her in her final moments. When officers arrested McKinven, of Pearmain Road in Street, they found 0.5g of cannabis on him, and detected cannabis in his system.In sentencing, Judge Paul Cook accepted McKinven 'genuinely' failed to realise Ms Howard was behind his vehicle, but told him 'your van had wing mirrors with an enhanced blind spot and she was there to be seen'. He also told the court the defendant had a 'history of offences and it shows a cavalier attitude to driving'. Despite McKinven having traces of cannabis in his system, the level was not above the legal limit for prosecution. However, Ray Howard, Ms Howard's son, argued it was an 'arbitrary cut-off point'.Mr Howard said his mother's 'sudden and brutal death' had left their family 'shattered'. 'Beryl was a loving mother, grandmother, and great-grandmother who brought immense joy and love to all who knew her,' he said. 'Knowing that McKinven was driving without a licence, without insurance, and after consuming illegal drugs only deepens our heartbreak and anger at the entirely preventable nature of this tragedy.'
