In a courtroom in Redwood City, Peterson will find out if he'll receive the jury's recommendation of death for killing his wife Laci and the couple's unborn child. Before he formally sentences Peterson, Judge Alfred Delucchi is expected to rule on a motion from the defense for a new trial.
Legal experts say it's unlikely that the motion will be granted.
Professor Michael Vietello of the McGeorge School of Law in Sacramento says it's also unlikely the judge would reduce the sentence from death to life without parole.
"State court judges are elected and to some extent they're not likely to rush out and let people off if the popular will is that this person ought to be put on death row."
Experts say if Peterson receives a death sentence it's probably going to be at least ten years before he would be executed.
If the judge supports the jury's recommendation, Peterson is expected to be whisk off to "death row" at San Quentin following the hearing.
