A July sentencing has been scheduled for a Pella mom and dad whose underweight 3-month-old daughter tested positive for cocaine. Marion County District Court records show 20-year-old Stazia Kirk and 21-year-old Zak Herman pleaded guilty last week to felony neglect of a dependent person. Court documents say their baby, Charlotte, weighed less than her birth weight when she was taken to a hospital in December. A doctor says the baby tested positive for cocaine and was suffering from malnutrition and dehydration. The documents also say Kirk and Herman recently admitted to using cocaine.
