A 16-year-old girl from rural Amboy charged with 4 felony counts of arson pleaded Not Guilty to the charges against her in Blue Earth County Court on Wednesday. Amanda Rae Ristau is accused of starting a pair of fires on her parents’ property in southwestern Blue Earth County recently. She allegedly reported the fires to police herself, and claimed to have used gasoline to start the barn and garage on fire. She also reportedly admitted to setting a nearby cornfield on fire at the time as well. No one was injured. The case will be assigned to a judge, but no trial date has been set at this time, and the case remains in juvenile court. Ristau is in the custody of Blue Earth County Social Services.
