Jack Donald Lewis (April 30, 1938 – legally d. August 19, 2002) is an American missing person who disappeared on the morning of August 18, 1997, after leaving his home in Tampa, Florida. The investigation into his disappearance has stretched from Lewis's Wildlife on Easy Street sanctuary in Tampa, co-owned with his second wife Carole Baskin, to land owned by Lewis in Costa Rica. No evidence of Lewis being murdered has surfaced, but investigators believe it is unlikely that he disappeared on his own. Lewis left behind over US$5 million in assets. He was declared legally dead in 2002 on the fifth anniversary of his disappearance.
