Marjorie was young and beautiful, longing for a glamorous life and searching for her Prince Charming. Over the years she found many of them and by the time she was 35, she was on her seventh marriage. In between these "fairytale" relationships, Marjorie's life took an X-rated detour. She became a stripper. And it was dancing that would ultimately get her everything she ever wanted.
In 1993, Marjorie was living in Las Vegas, Nev., still dancing and dreaming of a lavish life when she finally agreed to go out on a date with one of her strip club regulars who had pursued her several years before.
Jay Orbin, a traveling salesman from Phoenix, Ariz., was gregarious, big-hearted and head over heels for Marjorie, showering her with gifts. The couple, who appeared to be so different, really wanted the same things - marriage and a family. The couple eloped and settled in Phoenix. Then, after months of fertility treatments, Marjorie gave birth to what the couple called their miracle baby - a boy they named Noah.
Life seemed perfect when, in September 2004, Jay left on a business trip. His friends and family never saw him again. Six weeks later, a transient living in the desert came upon a gruesome discovery - a plastic container, neatly packed with a torso wrapped in heavy black plastic. It was found just miles from the Orbins' home.
Detectives quickly became suspicious of Marjorie following his disappearance. She went on a lavish spending spree and raided his business account of $45,000. Then it emerged that Marjorie was at the center of a love triangle, and investigators obtained surveillance video of her buying two large containers.
On Dec. 6, 2004, Marjorie Orbin was arrested and charged with the murder of her husband. After an eight-months-long trial, the former showgirl was convicted and sentenced to life in prison.
Now, in a series of video diaries obtained exclusively by "48 Hours Mystery," Marjorie discloses what she says are secrets she has kept hidden for years -- the truth about who killed Orbin, how it really happened and why.
