[The Guardian, 15 November ] A man in the US has been convicted of killing his pregnant wife and their unborn baby. Scott Peterson was found guilty of first degree murder for killing his wife, Laci, and second degree murder for the killing of the child who was to be named Conner. President Bush signed a law in April giving some measure of legal protection to unborn victims of violence, saying of the case: "This little soul never saw the light, but he is loved and he is remembered. All who knew Laci Peterson have mourned two deaths and the law cannot look away and just pretend there was only one."

His mother, Ruth, described pleading with doctors to give him an adrenaline injection, stating: "I got down on my bended knees and begged and begged for Luke's life." When she wagged her finger at the doctor, security guards were called. The Royal Liverpool Children's NHS Trust stood by the doctors concerned.
