A truck driver crashed into a car, killing a mother and her three kids while scrolling through his phone. Tomasz Kroker, 30, was distracted for just seconds leading up to the eight-vehicle crash in Poland. The tragedy claimed the lives of Tracey Houghton, 45, as well as her sons, Ethan, 13, and Josh, 11, and her step-daughter, Aimee Goldsmith, 11. Krozer was sentenced to ten years in prison.
