Colorless, odorless and tasteless, scopolamine is slipped into drinks and sprinkled onto food. Victims become so docile that they have been known to help thieves rob their homes and empty their bank accounts. Women have been drugged repeatedly over days and gang-raped or rented out as prostitutes.

In the case of Fernandez, the mother of three was rendered submissive enough to surrender her youngest child.

Most troubling for police is the way the drug acts on the brain. Since scopolamine completely blocks the formation of memories, unlike most date-rape drugs used in the United States and elsewhere, it is usually impossible for victims to ever identify their aggressors.
