PINE RIDGE, S.D. -

The Oglala Sioux Tribal Council has fired three tribal judges involved in giving custody of a 2-year-old boy to a mother who is now accused of killing him.
    
The council voted in a special session Monday to remove the judges, all of whom had been suspended in late August.
    
The judges were involved in a custody case in which the boy was taken from his guardian aunt and given to his birth mother, Katrina Shangreaux.
    
Authorities allege Shangreaux killed her son over potty-training issues in late July. She has pleaded not guilty to murder and child abuse. Shangreaux's mother, Sonya Dubray, has pleaded not guilty to hindering the investigation.
