Boston Globe 3/22/12: Grieving father hopes to turn loss into lesson. Outside Malcolm Astley’s home in Wayland, a swing tied with a coral-colored ribbon hangs from a tree branch, a delicate reminder of the years his daughter Lauren spent playing in the quiet, wooded yard. Inside are framed photos of her as a newborn, a toddler, a young tennis player. One collage shows her maturing through the years, but then stops, the last two slots blank. And there are piles of books with titles like "The Science of Evil: On Empathy and the Origins of Cruelty" and "Why Do They Kill?" Eight months after 18-year-old Lauren Astley was stabbed and strangled, allegedly at the hands of her former boyfriend, her father is struggling for answers. But the longtime educator has a few insights as he prepares to speak at Natick High School next month during a forum on dating violence among teens.
