Dr. Margaret Louise “Peggy” Clark loved her horses and loved her kids. She was a veterinary medical officer with the Department of Agriculture and only stopped at her office in the Alfred P. Murrah Federal Building for some last-minute business April 19. Clark’s husband is David Spencer, and she had three daughters – Rosslyn, 16, Blayne, 13, and Chelsea, 6. She was active in the Future Farmers of America and 4-H clubs at Chickasha High School, where her oldest daughter attended classes. Before joining the Agriculture Department in 1994, Clark worked as track veterinarian at Blue Ribbon Downs. Her predecessor at BRD – Dr. Brian Espe – also worked for USDA and was seen on television climbing down a fire ladder after the blast.
