A member of the Air Force faces a felony count of child abuse after police say she severely injured her baby boy.
Officers arrested 24-year-old Kaila Haller on Tuesday in Surprise.
They say she took her 1-year-old son to Cardon Children's Medical Center in Mesa with bruises on his face, neck, and two black eyes.
At first, detectives say Haller claimed the boy slipped and fell in the bath tub.
They say she later admitted to repeatedly throwing her son onto her bed.
Police took her into custody.
