decided to look into the death of todd's first wife in georgia. the more she dug, the more convinced she became that the previous wife's car crash was staged. the prosecutor now believed rachel's case was about more than one murder. but before she could make that argument to a jury, she would first have to convince the judge. here again is keith morrison. >> reporter: once, a long time ago, this part of california was the epicenter of the gold rush. back then, as legend has it, at least, there was no wait for justice. you committed a crime, the punishment was meted out then and there. but not now. for more than two years after the bloody confrontation in the winkler's nursery, todd waited in jail to be tried for her murder. >> and i just started just pacing around the house just saying, "god, i just killed their mother."
