Tracy Lynn Allen, 27, was known as a free spirited and spunky gal -- she worked as a care giver at a nursing home, liked to collect Indian art, and was a devoted mother to her two young daughters, ages 3 and 6. Tracy had recently gotten out of a volatile marriage with Garland Allen, but after their divorce the two remained in close contact. One early evening, in May 2001, Tracy went out while her neighbor babysat for their two young daughters. Later that night Garland arrived at the neighborÂs front door -- he told her that Tracy was back at his house, and she had asked him to pick up their daughters. Garland then drove off with the girls, and dropped them off at his motherÂs house. He told his mom that Tracy had run away with another man and had left him with the young girls. A few days later Garland surrendered custody of his kids to his mom, and then left town. It has been over 12 years since TracyÂs disappearance and no one has ever seen or heard from her again. They say the first 48 hours after a disappearance are the most crucial for police. The chances of finding the missing person drop dramatically after that. This case isn't cold -- itÂs frozen. It will be one of the most difficult cases Kelly, Yolanda, and team has ever taken on -- as they hope to help the tenacious Detective Bill Perkins from Altus PD, find out what truly happened to Tracy -- and hopefully bring some answers and closure to her family. CASE UPDATE: Garland Allen will remain in the Jackson County jail until his trial for the second-degree murder of Tracy Allen. Wanda is working to arrange a proper burial for her daughter. She hopes to be reunited with her granddaughters soon.
