A woman from West Virginia is looking at a sentence ranging from three to 15 years in prison after admitting to fatally poisoning her 81-year-old mother by injecting her with insulin for which she had no prescription.

Initially charged with murder in the 2023 death of Ethel Moore, Kelly Louise Moore, 61, recently pleaded guilty to voluntary manslaughter.

The plea deal stated, “Kelly L. Moore became upset and administered 20 units of insulin to her mother, who, despite being diabetic, did not have a prescription for it, leading to her mother’s death.”

Kelly Moore had originally faced a charge of murder, but prosecutors indicated that she lacked malicious intent.

“It wasn”t premeditated. It wasn’t done with malice,” Taylor County Prosecutor John Bord explained to Law&Crime about why his office offered the plea agreement.

The prosecutor said he was worried a jury might convict the defendant of involuntary manslaughter, which is a misdemeanor. Another issue, according to Bord, is that West Virginia law does not consider insulin a poison.

Bord said Kelly Moore flew “into a rage” during an argument with her mother and injected her with the insulin. While they were both diabetic, only the younger Moore was prescribed with insulin.

“It put her into shock,” said Bord.

Kelly Moore immediately called 911.

“I think afterward she regretted what she did,” Bord said.

Prosecutors will complete a pre-sentencing report and then set a date for a hearing where a judge will determine Kelly Moore’s fate.

As Law&Crime previously reported, police and paramedics in Grafton, roughly 140 miles northeast of Charleston, responded shortly before midnight on May 25, 2023, to a cardiac arrest call at an apartment. EMTs arrived and pronounced Ethel Moore dead at the scene, a probable cause arrest affidavit said.
