Shanna O'Hara Plunder is the daughter of a diamond miner named Gerald O'Hara. Born in Africa, she spent the majority of her childhood growing up in the jungles of Zaire. At the age of six, her father went to kill a rogue leopard that belonged to her mother, Patricia O'Hara. While hunting for the leopard, Shanna's father accidentally killed her mother. This traumatic incident led to Shanna's lifelong crusade against the use of firearms. After the incident, Shanna moved back to the United States to live with relatives. Shanna grows up to become an accomplished Olympic athlete, specializing in competitive swimming and track and field. She then became a licensed veterinarian.
