Anna Marie Arguello was two years old when she disappeared from her family home in Frankfort, Indiana, in the winter of 1969. Her absence remained unreported to law enforcement until 1992, when her sister Margarita, then 33, came forward after treatment for anxiety prompted her to disclose recurring nightmares and memories of that day.

Margarita told investigators their mother, Anita Maria Vega, forced Anna into a cold bath and held her head underwater until she drowned, then wrapped the child in an Army blanket and put the body in a turkey-farm cardboard box. Margarita said she overheard her stepfather, Luis Vega Sr., say he had buried the box near the railroad trestles, and later claimed their mother showed her a sack of dirt and bones she said were Anna’s remains. Anita initially denied having a daughter named Anna Marie and gave multiple, changing accounts when confronted with a birth certificate.

One sister, Guadalupe Thomas, later pled guilty to perjury and agreed to testify, admitting she had seen Anna’s body. In October 1993 Anita Vega was charged and convicted of involuntary manslaughter; she was sentenced to one to ten years and served three. Anna Marie’s remains have never been found.

Does anyone have memories of the Frankfort area in 1969 or information about the railroad trestles mentioned?
