Within a period of sixteen months, from June 1980 to October 1981, authorities in Jessup, Georgia, marked the sudden deaths of four related children, all of which remain unsolved. Successive coroner's reports could find no cause of death in any of the cases. As Detective Joel Smith explained to newsmen, "We have no idea what killed them. It's hard not to think there's some foul play in it, but we have no proof." The first to die was four-year-old Olympia Reddish, found in her bed on June 28, 1980, after playing outside in the yard. A year later, on July 14, 1981, Phyllis Worley was checking another of her children, 9-month-old Tiffany Reddish, when she found the infant stretched out in her crib, not breathing. Three days later, Tiffany was pronounced dead in the intensive care unit of a local hospital. That same morning, 19-month-old April Gaston -- a half-sister of the Reddish girls -- refused to eat her breakfast, returning to bed in mid-morning as if she felt ill. Looking in on the child a bit later, Ola May Gaston found her daughter dead. The final victim , two-year-old Latoia Reddish, displayed similar symptoms on October 13, 1981, refusing breakfast, complaining of a headache and stomach pains. Packed off to bed by her mother, Latoia was dead within the hour, leaving medical examiners without a clue to help explain her fate. Authorities reported that all four girls had the same father, although he resided with none of them. Paternal visits were infrequent, and the man had not been close to any of his children on the days they died. A physical examination of the father and his sole surviving child produced no traces of hereditary illness to explain the deaths. Detectives hold to their conviction of foul play, but there appears to be no likelihood of a solution in this baffling case.
