DR. SUZANNA DANA (in court): She had a number of what I call blunt force injuries to her face and her head. …

ALESSANDRA CRANSHAW: And what is this that we see behind the ear?

DR. SUZANNA DANA: That's a bruise. That's a contusion.

But during cross-examination, Hunter gets Dana to admit that at least one Cayley's injuries was caused by her medical care.

JOHN HUNTER (in court): So CPR can cause a lot of different injuries, not just simply superficial ones. Right

DR. SUZANNA DANA: Yes.

JOHN HUNTER: In this case, a rib was broken. Is that correct.

DR. SUZANNA DANA: I believe so. Yes.

Whatever the jury thinks about how Cayley died, they're about to learn much more about her troubled love life with Howerton.
