A teacher was allegedly caught on camera lacing her husband’s smoothie with a toxic lily.

The husband of Sarah Scheffer, 37, called police on Tuesday to say he ‘believed a period of unexplained illnesses were in fact an intentional act of poisoning’, according to the Jefferson City Police Department.

Cops responded to their Missouri home and Scheffer admitted that she added items to her husband’s food ‘with the knowledge of its potential to cause illness/death’, stated the police department.

‘A search of a national poison control center indicated all parts of the substance used contain numerous cardiac glycosides, which slow down the heart and cause irregular heart rhythm,’ the department wrote.

‘It is also categorized as having major toxicity signs of cardiac glycosides which cease nausea, vomiting, and abdominal pain.’

The victim confronted his wife on New Year’s Day after she gave him a drink that tasted ‘bitter’, according to probable cause document obtained by ABC News.

Scheffer claimed that she urinated in the drink and ‘admitted to putting an industrial strength adhesive in it’, the document states. However, she later denied spiking the smoothie.

Her husband went on to install a surveillance camera that recorded her making a smoothie for him and allegedly blending in a root from a ‘lily of the valley’ package that he had seen in their home.

Scheffer proceeded to put the smoothie in the refrigerator.

Cops seized the beverage and sent it to a state laboratory for testing, per the probable cause statement.

Scheffer, of Jefferson City, was arrested and charged with first-degree domestic assault. She has been booked into the Cole County Jail and awaits review by the county prosecutor’s office regarding the crime.

She was a Calvary Lutheran High School design and art part-time teacher, KMIZ reported.

It comes a few months after a North Dakota woman allegedly poisoned her boyfriend to death after discovering that he received a $30million inheritance and intended to break up with her.
