Finley was least seen sleeping in her bedroom in Orange, Texas, alongside her siblings and cousins  on July 4, 2002, according to Texas authorities.

The girl's mother, Jaime Arnold, told police that she put her daughter, two other children and three of her cousins to bed at 1:30 a.m. after returning from work. When she awoke at 10 a.m., Finley was gone.
