Evening of June 30: A car careens out of control on a busy Nanjing Street, killing five people, including a seven-month pregnant woman. Photographs taken by bystanders posted on various websites sickeningly show the fetus, with its umbilical cord still attached, ripped out of her stomach and curled up beside her body.

Her husband was killed, too, and a blossoming family felled in one swoop.

Just before she died, Zheng Lin, 27, wrote about her baby in her blog: "I can hear the beating of its heart. That's the most wonderful sound in the world. It's amazing."
