Bestselling author and forensics expert Patricia Cornwell examined the Trayvon Martin case on "Piers Morgan Tonight" and discussed with Piers Morgan how forensics will be a key component to the case. "What we're waiting for now is what did the medical examiner really find?" she explained. "What is the trajectory of the bullet? Was it a contact wound? Was it a slightly distant wound?"
Cornwell also mentioned how important the role of DNA evidence in the case will be, especially any DNA found on the gun. "Does it have Trayvon's DNA on it? Does it have his fingerprints on it, on it or the holster that might indicate he was grabbing for it?"
The forensics expert is interested to know if there was some sort of struggle. "How do we know that [the head wound] wasn't caused by maybe somebody who was frightened and hit somebody with their phone because it's all they've got in the hand or a bottle. Those should be checked for DNA, for evidence."
