WINCHESTER, Ind. -- Authorities say a Winchester woman accused of biting her 6-month-old granddaughter blamed the teeth marks on the family dog.

A probable cause affidavit says that 57-year-old Penny L. Huston also suggested to officials that the infant might have bitten herself.

Huston was being held on $10,000 bond in Randolph County Jail on felony charges of battery and neglect Monday night. The Associated Press left a phone message seeking comment from Union City attorney Ryan S. Prinkey, who was appointed to represent her.

Court documents say Huston insisted she didn't have enough teeth to bite the child, but police say gaps in her teeth "could very possibly" line up with the bite marks.

The baby's mother said Huston gave her conflicting explanations for the bite marks after taking care of the child for about three hours on Jan. 12.
