AMBER FREY'S FATHER TELLS "48 HOURS MYSTERY" THAT " 'FOR THAT FIVE-WEEK WINDOW, [SCOTT PETERSON] WAS THE GREATEST THING THAT EVER HAPPENED TO HER LIFE'" -- SATURDAY, OCT. 30

Amber Frey's father, Ron, tells contributor Maureen Maher, "A part of Scott was great in her mind. For that five-week window, that was the greatest thing that ever happened in [Amber's] life." Maher and correspondents Erin Moriarty and Troy Roberts report on the trial and a special mock jury that 48 HOURS assembled for a 48 HOURS MYSTERY: "On the Verge of a Verdict," to be broadcast at a special earlier time Saturday, Oct. 30 (8:00 -- 9:00 PM, ET/PT) on the CBS Television Network.

Maher witnessed Frey's courtroom testimony and speaks to her lawyer, Gloria Allred, about how Frey now feels about Peterson. Allred tells her, "I think her feelings about Scott Peterson are very complicated."

Also, Maher speaks to Dean Hoffinger, Frey's longtime friend, who reveals the hardships that Frey has overcome in her life. Hoffinger tells Maher, "Amber is 100 percent a survivor. That's her nature. Her whole childhood through everything I know about Amber�she is a survivor."

In an experiment to see how the Peterson jury might vote, 48 HOURS MYSTERY asked a leading jury consulting company to put together a mock jury that closely resembles the jurors hearing the Peterson case. Presented with actual prosecution and defense arguments and the same evidence -- including the secretly recorded Scott and Amber conversations -- the mock jury comes to its own verdict. Correspondent Troy Roberts reports.

Moriarty reports from Redwood City, Calif. on the eve of prosecution and defense closing arguments. She speaks to defense attorney Michael Cardoza, before a judge ordered him not to talk about the case, and former prosecutor Dean Johnson. Both men, who have been at the trial from the beginning, examine the evidence and offer their opinions as to what it all means for the jury. Cardoza was brought onto the defense team to help determine if Scott Peterson should take the stand.

48 HOURS MYSTERY: "On the Verge of a Verdict" is produced by Joe Halderman, Patti Aronofsky, Chuck Stevenson, Doug Longhini and Deborah Grau. The senior producer is Anthony Batson and the executive producer is Susan Zirinsky.
