As the June 5 elections approached, the anonymous phone calls to Mexican journalist Pedro Canché became more frequent and more ominous. "The Caribbean is a big sea, you'll never be found," one said. "I hope you've written a will," said another. A third caller told Canché, "Remember what happened to Rubén Espinosa," referring to the photographer murdered in Mexico City on July 31 last year. "Do you want that to happen to you too?"
