S1·E8 Bad Medicine

A series of suicides among high-society matrons coincides with a bizarre jewel theft by a towering Indian who mysteriously disappears when cornered. Kolchak investigates and finds that the Indian is a ""diablero,"" a cursed cliff-dwelling Indian medicine man condemned to walk the earth gathering an eternal horde of jewels. The diablero can change shape into the form of a coyote or crow, and hypnotize anyone with its eyes. Carl must seek the diablero in the highest place he can find, and turn the power of its eyes against it.
