One of the guests, Rosa Zaldosky, fell ill and went upstairs, and shortly after, another guest, Ella Mollie, also became extremely sick and died the next morning from strychnine poisoning.
Rosa had invited Ella and her sister to the party and asked if Ella liked raw oysters, which Ella said she did not. This seems suspicious since Rosa made oyster soup for the dinner, suggesting she knew Ella would avoid it.
Ella had a sensation in her feet, which spread throughout her body, convulsions, a swollen tongue, and her back arched in a convulsion before she died. These are classic symptoms of strychnine poisoning.
Rosa was the only other person who showed symptoms of illness, she had a motive as she was jealous of Dr. Mitchell's attention toward Ella, and she had access to the strychnine, which was kept in the house as rat poison.
After Ella's murder, authorities exhumed Minnie's body and found traces of strychnine. Dr. Mitchell testified that he had been medicating Minnie with nux vomica, a medicine derived from strychnine, which could explain the presence of the toxin.
Rosa's conviction was based on circumstantial evidence, and the community in Richland Center circulated a petition to appeal the case. The Supreme Court of Wisconsin declined to overturn the conviction, but Rosa was granted a pardon by the governor after serving six years in prison.
A chemist at Rush Medical College in Chicago found strychnine in Ella's stomach contents, which were removed and delivered for analysis. The chemist determined that the amount found was a lethal dose.
Rosa is believed to have laced chocolate creams with strychnine and given them to Ella and her sister Lily as a party gift. Ella complained about the bitter taste and began showing symptoms within 20 minutes.
The chocolate creams were the suspected vehicle for the strychnine. Ella bit into one and immediately complained about the bitter taste, followed by the onset of her symptoms within 20 minutes.
The trial was moved because many people in Richland Center knew about the case and were convinced of Rosa's guilt, which could have biased the local jury. The courtroom was packed, reflecting the high community interest in the case.
On today’s episode, Kate and Paul head to 1871 Richland Center, Wisconsin where a dinner party held at a doctor’s home sees some of its guests leave in great distress.
