Unsolved Disappearance: Karen Grajeda + Unsolved Homicide: Esther "Lizette" Galaz

About this episode

This episode discusses the unsolved cases of Karen Grajeda's disappearance and Esther 'Lizette' Galaz's homicide, believed to be connected.

When a 7-year-old girl vanishes while playing outside in a southside Tucson neighborhood, her disappearance is disturbingly similar to the abduction and murder of another child that occurred a year prior. Investigators are haunted by two unsolved cases they believe were likely committed by the same predator in this episode of Last Seen Alive.

The department welcomes tips given in Spanish as well as English, and you remain anonymous if you wish.
