Amber Frey becomes motivational speaker You remember Amber, right? She was the “mistress” of Scott Peterson, the man who murdered his wife and son. Well, Amber says that “there are so many women who can relate” to her own experiences, so she is becoming a motivational speaker(!). Uh, okay, maybe I am a bit out of touch — but how many women have adulterous relationships with men who murder their own families? Are there really enough of them to support her new career?
