Where Is Amber Frey Today?

"I haven't spoke with the family or had any type of connection … since my testimony," Frey said.

Frey says the most difficult part of the ordeal was being represented as the "mistress" in the media.

"I think that's probably the most frustrating thing for me," she said. "Every time I hear that, it's just, I feel that it's being misused."

Despite the media maelstrom, Frey says she has no regrets about going public about her relationship with Peterson or helping the prosecution.

"You know, I feel I have closure," Frey said. "I feel like there was justice. It was served through the legal system you know. Everything that I endured. … It was all worth it."

Frey also said she had not had any communication with Peterson, who sits on death row at San Quentin prison.

"I don't really have a need," she said. "I don't have anything, you know, left to say."

Frey is also not worrying about what will happen when and if Peterson is executed.

"I don't know if that will happen in our lifetime," she said. "If it does, you know, then just like anything else, deal with those emotions or those thoughts at that time."

'It Could Have Been Me'

Allred said that what helped Frey get through the ordeal was her integrity.

"One of the reasons I admire Amber so much and her courage, is because of the risks she took for justice. And she took that risk of recording Scott Peterson and all of his lies," Allred told "Good Morning America."

Frey is now married to 37-year-old Hernandez.

The two met when Frey, her 2-year-old son, and 5-year-old daughter moved into Hernandez's neighborhood.

"We were introduced through another neighbor out front, children playing outside," Hernandez said.

"It was very casual and other than that we were friends but basically neighbors. It was quite a while before we actually began to be any more than just as a neighbor, you know," he said.

The Peterson case is something Frey would like to leave in the past, though there were lessons she took away from that time in her life.
