HEIDI COLLINS, ANCHOR: Our top story this hour, one month to the day since Laci Peterson disappeared, attention turns to her husband, and a marriage now revealed as deeply troubled. First, Laci's family publicly withdrew its support for Scott Peterson. Then another woman reveals why. CNN's David Mattingly has this report from Modesto, California.</s>DAVID MATTINGLY, CNN CORRESPONDENT: It was a painful moment to watch, Laci Peterson's family struggling through a month's worth of terrible emotion, going before the cameras and appealing directly to whoever may have taken her, and pleading for her safe return. (voice-over): But the most powerful moment belonged to Laci's older brother, who claimed that Laci's husband, Scott, admitted to having an affair and questioned what else he may be hiding.</s>BRENT ROCHA, LACI PETERSON'S BROTHER: Since Scott is no longer communicating with anyone in Laci's family, and because we have so many questions that he has not answered, I am not -- no longer supporting him.</s>MATTINGLY: Then police revealed the girlfriend, 28-year-old Amber Frey, a single mother who claims a romantic relationship started with Scott Peterson one month before Laci's disappearance. Not knowing, she said, he was married, she called police and reported the affair after news of Laci broke.</s>AMBER FREY, ALLEGED FORMER GIRLFRIEND: I am very sorry for Laci's family. And the cause -- the pain that this has caused them. And I pray for her safe return as well.</s>MATTINGLY: A spokesman for the Peterson family said a response was not immediately available. And when questioned by reporters, Modesto policy repeatedly emphasized they could not say anything about the details of the case. (on camera): But when asked directly if they were any closer to solving this mystery and finding Laci Peterson, Modesto Police Chief Roy Wasden said, "I hope so."
