A four-month-old girl is at Upstate Medical Center and Cortland Police have arrested a woman from Homer for assaulting the infant.
Officers tell WXHC News that on Saturday evening at 6:30, Cindy Petrella, 52, was caring for the girl.
Police say she shook the infant violently leading to bleeding on the brain and say the girl was in critical condition at Upstate the last time they checked.
Petrella was arrested Monday afternoon and faces felony charges of assault, and reckless assault of a child.
Petrella’s next court appearance is scheduled for June 7.
