Her testimony helped put her former boyfriend on death row.

Now Amber Frey is hoping her experiences in the Scott Peterson murder case will serve as inspiration for other women facing rough times.

The California massage therapist says she's become a motivational speaker to inspire other women to bounce back from trauma. Frey says "there are so many women who can relate" to her own experiences.

Frey began an affair with Scott Peterson in the fall of 2002. Their relationship ended after Frey found out that Peterson's pregnant wife, Laci, had disappeared under mysterious circumstances.
