From USPS News Link:
When Brandon Spencer was delivering mail recently and saw legs sticking out from underneath a car in a garage, he initially thought someone was doing automotive work.
But when the Clinton, IA, city carrier assistant noticed an open car door and a dog loose in the back seat, he suspected otherwise.
Upon closer inspection, Spencer found that the man on the ground was unconscious. As he checked for a pulse, the man came to and said he’d recently been hospitalized for heart trouble.
Spencer, who was also recognized earlier this year for another heroic act, called 911 and stayed with the man until emergency responders arrived.
