On Halloween night 2005, by using a national symbol of trust � the uniform of a New York City firefighter � Peter Braunstein gained access to a former fashion editor's apartment, a woman he barely knew, and terrorized her for hours on end. Just last week Braunstein was sentenced to 18 years to life in prison after he was found guilty of kidnapping, robbing and sexually molesting the woman. In his first interview since committing the crime, Braunstein tells ABC News Correspondent Bill Ritter the details of that night, as well as what turned the one-time successful fashion journalist into a criminal. The exclusive interview airs on "20/20," FRIDAY, JUNE 29 (10:00-11:00 p.m., ET) on the ABC Television Network.

And: Is love blind? Can two people fall in love sight unseen? "20/20" goes behind the scenes of a modern day extreme dating game where the bride and groom have literally never laid eyes on each other until it's time to say "I do." WTMX radio in Chicago ran what they called a "social experiment" on their morning show. Relationship expert Judith Wright and sex therapist Dr. Laura Berman helped narrow down the candidates, who were subject to personality tests, background checks, even a lie detector test. Listeners selected the bride, Laura O'Connor, 31 -- and then the bride, after talking to five potential suitors on-air, selected the groom, TR Bell, 32. The potential lovebirds accepted the challenge of falling in love over two weeks' time without ever seeing each other. But for these two, getting to know each other involves phone calls that are being potentially heard by hundreds of thousands of radio listeners. How will it end? JuJu Chang reports.

Geller, who has trained dogs owned by Oprah, Ben Affleck and Nicolette Sheridan among many other stars, also tackles the dogs of some desperate "20/20" viewers who e-mailed videos to abcnews.com. Stossel reports.
