DIVORCE TURNS DEADLY: A RETIRED STATE TROOPER SHOOTS HIS WIFE AND HER LAWYER IN THE COURT PARKING LOT, ON ABC NEWS' "20/20"

And: John Nichols Went to Prison for Murdering His Mistress -- Would His Wife Forgive Him? Conquering Bad Habits; The Cheapest Family in America

Julie Porzio cannot look into a mirror without remembering the day she almost died, shot in cold blood for doing her job as a divorce lawyer. Known for her determination and toughness, she's seen her share of confrontational, explosive cases, but nothing prepared her for Bochicchio vs. Bochicchio. Julie's client was 42-year-old mother of two, Donna Bochicchio. Her husband, Michael, was a retired Connecticut state trooper. The divorce was ugly from the start, with battles over their children, the house, sex and money. It ended tragically as Michael Bochicchio shot his wife and her lawyer, Julie, in the parking lot of the courthouse, then turned the gun on himself. Julie speaks candidly to Don Dahler about cheating death: "I still see it in my head. I see a very determined, angry man," she says. "That's what it was like. He just had a look like, 'There is nothing that's gonna stop me from doing what I am about to do.'" The report airs on "20/20," FRIDAY, AUGUST 31 (10:00-11:00 p.m., ET), on the ABC Television Network. Dahler also talks to a psychiatrist about what kind of man could kill his wife and himself, leaving the children without parents.

Also: One gun shot changed the Nichols family forever. When 36-year-old John Nichols fired a shot that killed Carol Ramon, a 19-year-old mother, it revealed a complicated plot of love, murder and infidelity. Ramon was Nichols' mistress, who, just hours earlier, had exposed their affair to his wife, Diane. That one phone call between the two women set in motion a sequence of events that not only ended the life of a young woman, it all but destroyed the lives of John and Diane Nichols and their two daughters, Vanessa, 10, and Mariah, 3. That was August of 1996. John went to prison for murder. Diane divorced him, moved from Ohio to Florida, and eventually remarried a family friend. Would Diane and her daughters ever be able to forgive John? Don Dahler reports on a story of betrayal and murder, culminating in ultimate forgiveness.

Plus: Being messy, being a shopaholic, being late for everything, nail-biting, compulsively checking your e-mail, gossiping or hair twirling are all -- according to educator, life coach and author Judith Wright -- bad habits that are soft addictions. As JuJu Chang reports, often these bad habits stem from deep rooted problems. "20/20," with the help of Wright, brings together several people willing to go public in the hope of conquering their own bad habits, while helping other viewers do the same. (OAD: July 2006)

And: Is being cheap the answer to staying away from debt? The Economides family from Arizona just might be the cheapest family in America -- the family of seven lives a comfortable lifestyle on $35,000 a year, without credit. They've written a New York Times bestselling book entitled "America's Cheapest Family Gets You Right on the Money." Elizabeth Vargas reports. (OAD: Jan. 2007)
