Darryl Anderson was drunk behind the wheel of his Audi SUV, had his accelerator pressed to the floor and was barreling toward a car ahead of him when he snapped a photo of his speedometer. The picture showed a car in the foreground, a collision warning light on his dashboard and a speed of 141 mph (227 kph).

An instant later, he slammed into the car in the photo. The driver, Shalorna Warner, was not seriously injured but her 8-month-old son and her sister were killed instantly, authorities said. Evidence showed Anderson never braked.

Anderson, 38, was sentenced Tuesday to 17 years in prison for the May 31 crash in northern England that killed little Zackary Blades and Karlene Warner. Anderson pleaded guilty last week in Durham Crown Court to two counts of causing death by dangerous driving.
