Scott Peterson sits on death row in California's notorious San Quentin jail. He claims innocence of the appalling crime which resulted in his current predicament. If Peterson is one of those unfortunates who has been wrongly convicted, it is hard to imagine a more horrendous situation than the one he is facing.Because, according to the jury that found him guilty, he murdered his wife. A wife who was eight months pregnant at the time. Which means he also murdered his unborn child, a boy. A child so close to emerging into the world that his parents had already named him - Conner. Imagine that; to be accused of killing your spouse, and your unborn child. Of dumping your victim - if effect, two victims - into the sea (in Laci Peterson's case, the San Francisco Bay). Of murdering a person not yet even born, who literally had their whole lives in front of them. For once, the cliché speaks the truth.To be facing the unbelievable horror of your wife and your unborn child lost to you, then, astonishingly, to be accused of their homicide. To be hauled through a highly public five-month long trial before discovering that the State will execute you for a crime you did not commit, would never commit, could not conceive of committing. The despair of your fate, of what you have struggled through, is too immense for words.Or, on the other hand, what if you did commit that crime? What if the jury were right, and Scott Peterson did murder his wife and their unborn child. What kind of person can do that?
