What you describe happened after the trial. The offer of 3 years happened before the trial:
>An Alameda County Superior Court judge confirmed today Hans Reiser was presented a deal last year in which the convicted murderer would have only served three years in prison. During what was supposed to have been Reiser’s sentencing hearing – which has been delayed due to this week’s events – Judge Larry Goodman, in an effort to clear up what he called inaccuracies in the media, said that Reiser was given the opportunity last September to plead guilty to voluntary manslaughter. While voluntary manslaughter can carry different prison terms, Goodman said he agreed to give Reiser three years – the lowest possible term – to spare Nina Reiser’s family the turmoil of going through a trial and having the couple’s oldest son testify. Goodman pointed out in court if Reiser had accepted the deal, he would have been released in May 2008. However, Goodman said Reiser chose to “roll the dice,” and a jury convicted Reiser April 28 of first-degree murder in the killing of his wife.
