Mom serving 16 years for marijuana pens letter to daughters

When federal authorities stormed into Crystal Munoz’s home in 2007, she was three months pregnant and terrified. Already caring for a 4-month-old, the Native American mother was arrested on drug conspiracy charges and taken into custody. Authorities then told her a map she’d drawn on notebook paper — depicting a road in a Texas national park — had been used to evade a checkpoint in a marijuana trafficking operation. Suspects previously arrested had the map in their possession when they were caught.
