The body of a missing 8-year-old Northern California girl has been found stuffed in a suitcase in an irrigation pond on a dairy farm, reports the San Francisco Chronicle. Second-grader Sandra Cantu vanished after leaving home last month to visit a friend. FBI officials have joined an investigation by Tracy police. "All I can say is: 'Why?' She was a wonderful child, and very trusting," said a neighbor. "She loved everybody. She was happy."
