Love potions are said to help brainwash a person into loving the poisoner unconditionally! Doretha had already tried to poison Tumpowoski, when having had bought the poison from Bird, the witchdoctor. Unfortunately for her, it did not work in her favour instead sickened the Jewish man.
The body of Dorethea's lover, Tumpowoski, was found on the 20th of September in 1920 when he had been buried for almost two and a half years on the edge of the ash pit, near the back door of Dorethea's farmhouse. Ironically Tumpowoski's body was found by the fortunate witch doctor, Bird.
