Woman goes public

The Laci Peterson case took a dramatic twist Friday when a 28-year-old single mother acknowledged having a recent romantic relationship with Scott Peterson.

Amber Frey, who lives in the Fresno area, said in an emotional news conference Friday night that Peterson told her he was not married when they met Nov. 20.

On Dec. 30, Frey contacted police after seeing Scott Peterson's photo in reports regarding his wife's disappearance. She has been eliminated as a suspect in the investigation, Modesto Police Chief Roy Wasden said.

Scott Peterson did not answer his home or cell phone on Friday night, and he did not return messages seeking comment. Wasden said Peterson has not been eliminated from the investigation.

Hours earlier, Laci Peterson's family held its own emotional news conference at the Red Lion Hotel.

"Scott Peterson did admit to me that he was having an affair with a Fresno woman," said Brent Rocha, Laci Peterson's older brother. "I trusted him and I stood by him in the initial phases of my sister's disappearance. However, Scott has not been forthcoming with information regarding my sister's disappearance. I'm only left to question what else he may be hiding."

Last week, a Rocha family member said detectives had told them of Peterson's recent affair and that he had taken out a $250,000 life insurance policy on his wife during the summer.

Asked about the report the next day, Scott Peterson told a Bay Area TV reporter, "It's a bunch of lies."

Eight days later, Frey stood in front of dozens of reporters at the Police Department and spoke about her relationship with Scott Peterson. Police revealed the woman's identity because several reporters had started to contact her, Wasden said.

"When I discovered he was involved in the Laci Peterson disappearance case, I immediately contacted the Modesto Police Department," Frey said. "I am very sorry for the pain this has caused Laci's family, and I pray for her return."

Frey's voice shook and she cried several times as she spoke, occasionally taking measured breaths before continuing with her statements.

Emotional day for friends

A group of Laci Peterson's friends stood behind the rows of TV cameras and took in Frey's words. They displayed very little emotion. As soon as Frey stopped talking and left the room, most of Laci Peterson's friends also exited.

"It's emotional for these girls to see her," said Terri Western, whose daughter is a close friend of Laci Peterson's. "But they applauded her for coming forward with this information. This whole thing is absolutely the worst and most difficult thing any of them have ever had to deal with."

Janey Peterson, Scott Peterson's sister-in-law, said later on CNN's "Connie Chung Tonight" that she did not know Scott Peterson had an affair until she heard the news Friday.

"It would not change what I am doing to help find Laci," Janey Peterson said. "And, to be honest, we don't have the extra emotions and we don't have the time to chase down all these peripheries. Trusting in the Lord is all that we have."

Laci Peterson was about eight months pregnant when she was reported missing on Christmas Eve. Her husband told police he last saw her that morning as he left to go fishing in Berkeley.

The case has drawn intense media coverage. Frey implored her friends not to talk to reporters, and Wasden asked the media to respect the privacy of the woman and her 23-month-old child.

"I do believe our entire nation and possibly most of the world is aware that Laci Peterson is missing," Wasden said. "Now, what this is starting to do is border on pretty close to being destructive. We've given the information we feel we need to give so that a young woman who had the courage to come forward and give us information will not be harassed as she tries to go on with her life."
