 Convicted murderer Scott Peterson is returning to court seeking a new trial. On Monday, a judge in a Redwood City, California courtroom is expected to rule on DNA testing on what Peterson's legal team says is a key piece of evidence. A piece of duct tape that was found inside a suspicious van is among several pieces of evidence that Peterson's lawyers and representatives from the Innocent Project say were suppressed from the original trial. Peterson is serving a life sentence for the murder of his wife Lacey and their unborn child.
