Don and I worked together on the Chicago Counterfeit Squad many years ago. We sat across from one another in the office and did some socializing together.
We reconnected a few years ago through our writing.
Don spent 25 years in the Secret Service and in Narcotics before that. He was one of the great undercover agents in both agencies. He finished his career at the agent in charge of the Phoenix, AZ field office and then served as U.S. Marshall for Arizona. Don grew up in poverty and gang territory in south Chicago and played football at the University of Iowa. He has written two books available at Amazon.
His television interview is worth watching.
