(CNN) -- Greg Allen's obsession with finding his missing daughter began more than a decade ago, when the mother finally made good on a threat and fled with the daughter from Texas to Mexico, according to him and authorities. Sabrina Allen was a month away from turning age 5, and the visit with her non-custodial mother, Dara Marie Llorens, was supposed to last only a weekend in April 2002, as part of a court agreement. But that weekend visitation in Austin lasted 12 years and finally ended Tuesday, when Mexican and U.S. authorities said they found the girl and her mother living in seclusion in a small apartment in a town between Mexico City and Puebla. The mother will face charges in Travis County, Texas, said Dan Powers, an FBI assistant special agent in charge in San Antonio, Texas.
