A FAMILY RETURNING FROM VACATION IN MEXICO IS AMBUSHED AND KIDNAPPED AT GUNPOINT AS THEY APPROACH THE U.S. BORDER ON 48 HOURS MYSTERY LIVE TO TELL: "KIDNAP ON HIGHWAY 1"

In November of 2007, Chris and Debra Hall, along with their children, Tyler and Divinia, were driving back to California from Mexico, when they saw police lights gaining on them. When the family pulled over, a man in a police uniform approached and suddenly put a gun to Chris' head. Drug gangs in Mexico are known to wear police uniforms as a way to trap their victims and moments later the family was ambushed by a second car of gunmen. They were only a few miles from the U.S. border. As the kidnappers drove them onto a dirt road in the mountains outside Tijuana, they began asking about a race car. While in Mexico, Chris and Tyler worked as part of a pit crew at the Baja 1000. But when Chris explained that there was no race car, the men ransacked the family's trailer and then took them farther into the dark mountains. The gunmen put the family in a ditch and threw sleeping bags over them.

Suddenly, as the Hall family lay hugging in the ditch, the men drove away. Ultimately the Halls crawled through the brush in the night to a house where a woman took them in and called police for help. Despite her assurances that they could trust these officers, the family could not help but fear they were in trouble all over again. But the authorities rushed them to the border. For the moment they were safe, but with the gunmen in possession of their drivers' licenses - and their address - it would take time for their fears to subside and they will carry the traumatic events of that night with them forever. Now the Hall family recounts their terrifying brush with death.

IN A SERIES OF EXCLUSIVE VIDEO DIARIES, A SHOWGIRL REVEALS SECRETS ABOUT THE WEB OF SEX, LIES AND GREED THAT ENDED IN MURDER ON 48 HOURS MYSTERY: "DIARY OF A SHOWGIRL"

In 1993, Marjorie Orbin was living in Las Vegas, Nev., 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 - eloped and settled in Phoenix. Marjorie also gave birth to what the couple called their miracle baby - a boy they named Noah.

Life seemed perfect when, in September of 2004, Jay left on a business trip, never to be seen 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.

Convicted of a murder she claims she did not commit, Marjorie Orbin has been living behind bars, a far cry from the extravagant lifestyle she had been accustomed to. 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.
