Fighting for Her Life
California housewife Susan Polk studied literature, not law, in college. But she has chosen to act as her own attorney at her murder trial, "fighting for her life," she says, against the first-degree murder charge in her husband's death. Polk admits she stabbed her husband Felix in 2002, but says it was in self-defense during a fight and that he actually died from a heart attack and not his wounds. Two of her three sons say she is "delusional" and guilty as charged.
