Scott Peterson, charged with the murder of his wife Laci Peterson and their unborn infant, appeared at a Stanislaus County, Calif., Superior Court hearing Monday, during which his new attorney, Mark Geragos, argued that arrest and search warrant records should be sealed in order to avoid “a voodoo-like investigation,” reports the Associated Press.

If Geragos’s name sounds familiar, that’s because his most recent high-profile client was Winona Ryder, who was convicted on shoplifting charges last year.

Telling the court that he had yet to view the records, Geragos suggested that they could include references to “psychics and voice stress analyzers, all of which are totally inadmissible,” reports AP.

Outside the courtroom, Geragos told reporters he would prove his client’s innocence and “find out who did this to Scott’s wife and Scott’s son.” Peterson, 30, has already entered a plea of not guilty.

Stanislaus County prosecutors are seeking the death penalty in the case.

Peterson’s mother, Jackie, of San Diego, also told reporters, “Our son is innocent, and we once again feel the truth will come out. We have faith in the legal system.”

In court Monday, the former fertilizer salesman wore a dark blue suit. At his earlier hearing he had been outfitted in chains, sandals and a one-piece jail jumpsuit.

The court proceedings came a day after more than 3,000 mourners remembered Laci, 27, and her unborn son, Conner, during a nationally televised memorial service in Modesto.

Their remains washed up in San Francisco Bay three weeks ago, and Peterson was arrested days later in San Diego.
