Authorities say Sabrina was abducted by her non-custodial mother in April 2002 and they have managed to stay one step ahead of the FBI...
Greg Allen's whirlwind marriage to Dara Llorens ended when he uncovered her plan to flee with their daughter, Sabrina, to start a new life in Mexico.
During divorce proceedings, a court psychologist determined Dara suffered from personality disorders. To Greg, it explained some of Dara's bizarre behavior.
But to the courts, it meant that Dara was too unstable to be a full time mother, and Greg Allen was awarded full custody of Sabrina.
Shortly after the ruling, Dara reported her husband to the Child Protective Services claiming Greg was sexually and physically abusing Sabrina.
After a lengthy investigation, the CPS determined there had been no abuse. They believed Dara had been fabricating the stories and as a result Dara was ordered by the court into therapy.
Unhappy with this outcome, the FBI says Dara Llorens took her daughter Sabrina and disappeared.
Dara and Sabrina were living on the run, but in this post 9-11 era, little was being done by law enforcement to find them.
Greg Allen turned to AMW for help. His fear for Sabrina's safety outweighed his anger towards Dara. With Dara's inability to hold down a job or find a place to live, Greg was concerned Sabrina was not eating and did not have a place to sleep.
AMW assembled a team of retired NYPD detectives, Ron Antoci and Jim Rodriguez, to search for Sabrina.
They quickly picked up Dara's trail that led from Austin to San Antonio to a busy bus depot in Nueva Laredo, Mexico. Antoci and Rodriguez found two attorneys in Mexico City who each had given Dara $1,000, but neither knew where she and Sabrina were hiding.
It was as though Dara and Sabrina had literally slipped through the cracks.
Greg Allen wasn't giving up hope, but it was now over a year, and still no word on his young daughter, Sabrina.
Then on June 10, 2003, Greg got the news he'd been waiting for. It came in the form of an e-mail and it was written in Spanish.
A teacher at a Mexico City pre-school was convinced one of her students was Sabrina, only this malnourished 6-year-old had dyed black hair and was called "Blanca".
The FBI quickly determined Blanca was indeed Sabrina and located where she and her mother Dara were living in Mexico City.
However, when Mexican Authorities went to detain the pair, Dara barricaded herself in her house and refused to cooperate. She agreed to voluntarily turn herself in two days.
When Dara was a no show, authorities returned to her home, only to find that Dara had taken Sabrina and vanished once again.
