Detroit Postal Police Officer David Richardson

On a recent afternoon in Detroit, Postal Police Officer David Richardson responded to a call from a Post Office supervisor who was threatened by a customer.

Several hours later, when Richardson returned to ensure the supervisor’s safety at closing time, he noticed a car that had been there during his earlier visit.

As Richardson approached the vehicle, he recognized the occupant as a customer from that afternoon — not connected to the threat — and the man was unconscious.

Richardson called 911 and stayed with the man until emergency responders arrived, revived him and determined he’d gone into a diabetic coma as a result of low blood sugar.

At the request of paramedics, Richardson gave the man candy to help alleviate his symptoms.

The customer declined to be hospitalized, and a family member was contacted to take him home.
