“We never found the tip of the finger. We don't know whether she ate it or swallowed it. Totally out of control. We don't know if she was high on drugs or what,” added Superintendent Chitwood.

Kirstie L. Foley is now wanted for aggravated assault, simple assault and harassment.

Though the incident occurred over the weekend, Foley’s mother is still in the hospital due to the severity of her injuries.

"She almost took off the thumb," Chitwood said. "Nasty."
