A high school teacher in Missouri is charged with attempted murder, with authorities alleging she poisoned her husband.

Sarah Scheffer, 37, was allegedly caught putting a root of a plant known as lily of the valley into her husband’s smoothie after he set up a hidden camera in the kitchen, according to a probable cause statement filed by the Jefferson City Police Department.

The alleged victim became suspicious when he started experiencing “extreme fatigue, confusion, blurred vision, severe cotton mouth and nausea” after eating or drinking on eight different occasions, according to the probable cause statement.

On Jan. 1, police say Scheffer brought the alleged victim a drink, which had a bitter taste, and he confronted her about it. In response, she allegedly told the man she had urinated in the beverage, before saying she put an industrial strength adhesive into it, according to the statement. Scheffer later denied putting anything in the drink, police say.

After that incident, police say the alleged victim installed the surveillance camera in the kitchen.

On Tuesday morning, the alleged victim found a bowl containing a root from a bag labeled “lily of the field” on a table in Scheffer’s home work area, the statement says. That same morning, police allege that the camera captured Scheffer pouring the bowl’s contents into a blender, which the man says was a smoothie she prepared for him, according to the statement.

Police claim Scheffer admitted that she blended lily of the valley into her husband’s smoothie, despite knowing it could potentially kill him, allegedly saying she intended to harm him.

Lily of the valley contains cardiac glycosides, which slow the heart.
