Joining Burke at his announcement were Officers Alejandro Cabral and Juan Zuniga. The two cops said they used the clotting gauze that Cabral purchased with his department allowance to stop the bleeding from a man's chest wound when they discovered him shot at a gas station in the South Chicago neighborhood. Cabral, a former Army medic, had used the gauze while serving in Afghanistan and said he bought it because he believed it could help him or his partner if one of them got shot.
