Additional tests showed the infant had two separate injuries to his brain: a month-old injury to his frontal lobe and a new injury to the top of his head. The infant also had retinal hemorrhages in his left eye.
"It appears to him (doctor) that the injuries are a result of the baby being shaken,” the affidavit states.
About a week after the child was hospitalized, Coulter told investigators she had forgotten to tell them that when the child was crying, she tossed him in the air twice. On the last toss, his hair brushed the ceiling but his head didn't hit, she said.
Doctors said the child's injuries would not have come from being tossed in the air or hitting his head on the ceiling. Those acts, if injurious, would have caused immediate symptoms, according to a court affidavit.
Coulter's attorney, Brian N. Lovell, was not available for comment.
