SAN ANTONIO (AP) – Investigators say a San Antonio-area couple punished their three young children by forcing one to brush her teeth with cat feces, using a shock collar as punishment and beating them with a thorny switch.

James Chalkley, 32, and 22-year-old Cheyanne Chalkley were being held Tuesday on charges of injury to a child.

James Chalkley is the father of a 3-year-old boy and two girls who are 5 and 10. Cheyanne Chalkley is their stepmother.

Arrest warrants show a teacher noticed bruising on the 5-year-old in September. Investigators say interviews with child-protective workers revealed the extent of their punishments.

The 5-year-old told authorities that her father used a dog’s shock collar on her that left green marks on her skin.

Jail records indicate no attorneys have been appointed for the Chalkleys.
