Regarding the photo of the dead bomber - medical information

The chest wound looks as if they tried to intervene to save his life. In addition to the leads on his chest to monitor vital signs and IV's that were inserted, you can see betadine (that yellowish color) around the wound. Betadine is an anti-bacterial solution used in the OR and trauma situations. I imagine he had a chest injury (such as a pierced heart or artery from a bullet) and they were trying to stop that. I'm sure they'd want him alive for investigation purposes. Being in the medical field I just wanted to shed some light on that gaping wound.
