After nearly 12 years of military service, Leslie Walker worked as a cryptologist and engineering specialist with the National Security Agency. He retired in 1992 having earned the National Intelligence Distinguished Service Medal and with 40 years of service to the United States. Mr. Walker was very active in the Laurel community as a member of several organizations. As Secretary of the Laurel Jaycees, he helped raise funds to buy equipment for the Laurel Volunteer Rescue Squad. He worked as police photographer for the Laurel Police Department, eventually becoming a part time patrol officer. Starting as a pilot in the Air Wing, he joined the Laurel Volunteer Rescue Squad. When the Air Wing was disbanded, he earned his Emergency Medical Technician–Ambulance Certification and provided first aid in the Squad ambulances, eventually moving to the heavy rescue truck as driver.
