An attempted homicide using d-CON rat poison

Two adult residents became ill after ingesting food and medication allegedly tainted with d-CON. Police later recovered a box of the poison from the household of the residents and immediately arrested their teenage daughters for attempted homicide. Samples of the food and medication were analyzed for Warfarin, the active ingredient of d-CON, using ultraviolet spectrometry, gas chromatography, and gas chromatography/mass spectrometry. Results confirmed the presence of Warfarin in both the food and medication.
