1966 Press Photo Escaped snow leopard tumbles from rooftop tumbling from dart.

Ivan the Terrible, a rare and valuable snow leopard that escaped from Oklahoma City's Lincoln Park Zoo, tumbles from a rooftop, drugged from a dart fired into his hip. The dart still protrudes from his hip. The leopard spent 27 hours of freedom until he was caught early today in a net held by the men at the base of the building. A short time later the leopard died from effects of the tranquilizer.
