December 4, 1978.In an appalling demonstration of the way in which a charismatic leader can bend the minds of his followers with a devilish blend of professed altruism and psychological tyranny, some 900 members of the California-based Peoples Temple died in a self-imposed ritual of mass suicide and murder.The followers of the Rev. Jim Jones, 47, a once respected Indianaborn humanitarian who degenerated into egomania and paranoia, had first ambushed a party of visiting Americans, killing California Congressman Leo Ryan, 53, three newsmen and one defector from their heavily guarded colony at Jones-town. Then, exhorted by their leader, intimidated by armed guards and lulled with sedatives and painkillers, parents and nurses used syringes to squirt a concoction of potassium cyanide and potassium chloride onto the tongues of babies. The adults and older children picked up paper cups and sipped the same deadly poison sweetened by purple Kool-Aid.This story is part of the TIME Classic Coverage Collection from Time Inc.
