An 84-year-old woman has been charged, police say, after she attempted to kill her 83-year-old husband and herself.

Officers were called to a London home around 7:30 p.m. Sunday by EMS, who had responded to the scene after a family member found the couple in medical distress and called 911.

Police say the woman had signed her husband out of his long-term care facility and took him to her home, where she gave him a quantity of medication and then consumed a quantity of it herself, making them both ill.

The couple was transported to hospital by ambulance. The man has since been treated and released while the woman remains in hospital in good condition.

Investigators say the woman also tried to poison two cats in the home, but neither was harmed.

According to police, the 83-year-old man suffers from dementia related to a medical condition.

London police Const. Ken Steeves says, "There's no indication he had any knowledge, nor was he a participant in relation to this incident, therefore she's being charged with attempted murder."

In addition to attempted murder, the woman has been charged with administering a poisonous substance to a domestic animal.

She is scheduled to appear in court on Nov. 18.

Due to the nature of the incident and the relationship between the victim and the accused, police are not releasing names in the case.
