The EMT is putting pressure on what is probably the primary wound on upper chest. I do see surrounding purplish bruising on her upper left chest. Lower on her side it looks like there is a dressing for a sucking chest wound. (Russell? Yellow tape w red vent at top?)
That there is a primary wound area and an apparent secondary would seem to indicate that a either a piece of glass was responsible for one of the wounds or the round or round fragment was deflected from the primary site and exited in the location of the lower dressing. Also note that there appears to be an IV line across her stomach.
The blood draining from her mouth is bright red, which indicates an arterial bleed. If any of the round exited from her back you would see blood on her back shoulder, which I do see.
Any ER Doctors or EMTs reading this care to comment? She looks to me like she has passed at this point.
If someone wants research for pictures of DC EMTs and Firefighters and compare them with the people in the youtube above. If you find them and they are real Firefighters and EMTs then it would support her being for-real dead.
