The family of a woman who was killed by joyriders say the hit-and-run death of nine-year-old Ross Doyle has brought back haunting memories.

Maureen Morris, 66, was killed on December 22, 1999, when a stolen car driven by joyriders careered into her as she crossed Priory Road, outside her home in Oxford.

Mrs Morris had ten children and 22 grandchildren. They say the death of Ross Doyle has reawakened their pain and the frustration that nobody has been convicted.

Mrs Morris' son Michael, 50, also said his family was angry that police had not offered a reward to help catch his mother's killers after they offered £10,000 for information to catch the driver of the car that hit Ross Doyle.

Ross was killed after being struck by a joyrider driving a Vauxhall Astra in Pegasus Road, Blackbird Leys, at about 8.45pm on December 13.

Mr Morris said: "We thought about setting up our own reward to catch these people but I can't understand why the police offer a reward for one life and not for another."

He added that the family totally supported Ross Doyle's family, but felt their mother's case was just as deserving.

He said: "We just want to remind people that these people are still at large. Somebody knows who did it and we desperately want them to call the police."

A police spokesman said the investigating officer took the decision not to offer a reward to bring forward witnesses, but declined to explain why.

Det Insp Dermot Norridge, of Oxford Police, said: "In light of the Ross Doyle appeal, information has been received regarding the accident in 1999 where Mrs Morris was tragically struck down.

"The file regarding this matter is currently being reviewed by me to establish whether or not this can be taken further in an attempt to bring the driver of the stolen car before the court. I have been in contact with the family of Mrs Morris."

Four men were arrested in connection with her death, but no charges brought. At the inquest, the coroner recorded a verdict of accidental death.

The file into Mrs Morris's death has not been closed and the police have urged anyone with information to call them.
