A babysitter is being tried for the death of a 10-month old infant. The prosecutor contends the child died as the result of being violently shaken. The defense claims that the child's head became stuck in the slates of his crib and, in trying to twist free, he broke his neck. The medical examiner testifies that the child died as a result of compression of the spinal cord between the 6th and 7th vertebrae. The superior articular processes of the seventh cervical vertebra were fractured, and the processes on the right side were laterally displaced, causing the 6th vertebrae to slide laterally across the seventh, damaging the spinal cord. How did the infant really die? Support with details.
