In January 1981, two women, Helga Franks and Anna Russell, were having dinner with their three children, ages 1½ to four years old, during which the three children became seriously ill. An investigation determined that the Kool-Aid the children had been drinking had been laced with cyanide. The adults did not partake in the Kool-Aid, so were not affected. The children made a complete recovery.
Subsequent investigations seemed to focus on a chap named Harry Leland Leach, who was thought to have been the tamperer.
Was Leach ever brought to trial, and if so, what were the results?
