A van driver who fell asleep at the wheel and killed a mother has had his “excessive” four year jail term cut to three years.

Shanmugarasa Vinayagasivampillai, of Meadway, Surbiton, hit Louisa Gammie, 35, from Worcester Park while she was out jogging in Old Malden Lane on the morning of November 8 last year.

Mrs Gammie, the mother of a 20-month-old child, died in hospital a day later from a serious head injury.

Vinayagasivampillai pleaded guilty to causing death by dangerous driving in April and was sentenced on May 22 in Guildford Crown Court.

On Friday at a Court of Appeal hearing, however, three senior judges agreed the sentence was too long and reduced it to three years.

Vinayagasivampillai had worked seven consecutive 12-hour supermarket night shifts before the crash, as well as day shifts elsewhere, Get Surrey reported.

Mrs Justice Patterson said the original sentence did not reflect Vinayagasivampillai's mitigation and deep remorse for what had happened.
