Letter Carrier Andre Scott was nearing the end of his route in Addison, IL, when he encountered a slumped-over driver inside a stopped vehicle at a busy intersection.
Scott checked on the unresponsive man, speaking and clapping his hands to try to provoke a reaction. None came.
The Postal Service employee called 911 and waved down a police car. He and an officer performed cardiopulmonary resuscitation on the man until other emergency responders arrived to take over.
Paramedics used a defibrillator to eventually revive the man.
