So far, the case against Scott Peterson is almost entirely circumstantial.

Most murder cases are entirely circumstantial, because very few people kill another person in the presence of third parties.

I disagree. Frequently there is forensic evidence. Bullets in the body, knife wounds, fiber samples, blood with DNA evidence, footprints and fingerprints all come to mind.
