A Ferris, Texas, woman has pleaded not guilty to allegations that she had her 9-year-old granddaughter plant drugs in her son-in-law's car in Arizona so the grandmother could gain fulltime custody of the child.

A Maricopa County Superior Court spokeswoman says 58-year-old SanJuanita Carabajal's next proceeding on a charge of involving a child in a drug offense is scheduled for Jan. 2.

Gilbert police say Carabajal gave the child several packets containing 4 grams of cocaine and told her where to put them in her father's vehicle.

Carabajal also allegedly told her granddaughter to tell people about the drugs at her elementary school and show one of the baggies to a teacher.

Messages left Wednesday afternoon for Carabajal's attorney, Melinda Kovacs, weren't immediately returned.
