Police have charged a nurse in southwestern Ontario with murder alleging she killed eight nursing home residents by administering a drug.
Investigators say 49-year-old Elizabeth Tracey Mae Wettlaufer of Woodstock, Ont., was charged with first-degree murder in the killings, which they say took place between 2007 to 2014.
Police would not elaborate on the drug allegedly used, saying only that a number of drugs were stored and accessible in nursing homes.
The victims were between the ages of 75 and 96. Seven of them were living in a Caressant Care facility in Woodstock, Ont., while another lived in a Meadow Park facility in London, Ont.
Police said they believe Wettlaufer also worked at other long-term care facilities in the province but could not specify which ones, nor would they speak to a motive.
They said the investigation is ongoing and more charges could be laid in the future.
