Scott Peterson is scheduled to be sentenced today in the slaying of his pregnant wife, Laci Peterson.
Peterson was convicted last November and the jury voted for the death penalty. The judge has the option of reducing that to life in prison without parole. But a change from the jury's recommendation would be unusual.
Peterson's lawyers have filed a motion for a new trial, arguing that newly discovered evidence could have brought a different verdict. A 135-page motion unsealed this week cites legal errors, misdirection of the jury, jury misconduct, evidentiary issues and insufficient evidence to support the guilty verdict.
According to the defense, prosecutors withheld key evidence that a state prison inmate claimed to have information about Laci Peterson's disappearance.
