Here to explain is Dr. Ashley Saucier, a physician in Louisiana, board certified in pediatrics and pediatric emergency medicine.

In 2009, the AAP, American Academy of Pediatrics, released a statement that said, you know, we're not gonna use the term shaken baby anymore.

We're gonna use the term abusive head trauma.

But Dr. Saucier reviewed Cody's hospital records obtained by Dateline and found other possible explanations for his death, possibilities like a bleeding abnormality or an infection that triggered sepsis.

I find it, um, upsetting that only one diagnosis was made, and that was shaking, so that this intracranial bleed was only the result of shaking.
