Two nurses, who had been walking along the street, witnessed the cars colliding and immediately assisted the boys by starting CPR on Mark, who at this point was pale and lifeless. At the same time, a passing motorist flagged down Corporal Danny Hahn's patrol car and reported to the officer that a motorist had become unconscious. Hahn raced to the scene to assess the victim's status. After determining Mark had no pulse, Hahn ran to his trunk for his automated external defibrillator (AED), which had been recently purchased by his department. Hahn applied the pads to Mark's chest and turned on the device. As the AED analyzed Mark's heart, it detected a shockable rhythm and verbally instructed Hahn to administer a shock. After the second shock, Mark's vital signs began to return. The paramedics arrived on the scene and Hahn's job was completed.

It was only after someone showed Cpl. Hahn Marks badge that he realized he had just saved the life of a fellow officer, or, as he says, "a member of the family." Hahn refused to take any credit, and felt that he had done what he was trained to do at the scene of an accident; but being a lifesaver is an experience that will stick with him for a long time. "I'll never forget this, he said. "He is a family member. He is a policeman."
