The "San Francisco Evening Bulletin" trumpeted the news with the March 1 headline "Mrs. Stanford Dies, Poisoned." Forensic chemical analysis revealed the presence of a pure form of strychnine in samples from the bicarbonate she had taken, as well as traces of the poison in her tissues. After hearing three days of testimony, the coroner's jury concluded in less than two minutes that she had died of strychnine "introduced into a bottle of bicarbonate of soda with felonious intent by some person or persons to this jury unknown." The testimony revealed that the bottle in question had been purchased in California (after Richmond had been let go), had been accessible to anyone in Stanford's residence during the period when her party was packing, and had not been used until the night of her death.
