Police are investigating two other deaths at a nursing home where a nurse accused of killing eight elderly patients worked, CTV London has confirmed.

In late October, police charged Elizabeth Wettlaufer with eight counts of first-degree murder in the deaths of eight seniors who were living in nursing homes at the time of their deaths: Caressant Care in Woodstock and Meadow Park in London. Police said the homicides occurred between 2007 and 2014, when patients were allegedly administered a drug.

Wettlaufer was registered with the College of Nurses of Ontario in 1995. She resigned in September of this year.

Wettlaufer, 49, made a brief appearance via video link in a courthouse in Woodstock Thursday morning. The case was put over to Jan. 6, and Wettlaufter was remanded into custody.

CTV London confirmed Thursday that police are investigating two other nursing home deaths. However, authorities would not provide any other details.

Ontario Provincial Police Sgt. David Rektor said the case is an “ongoing” investigation.

“We continue to follow up on numerous leads that have been and continue to be provided to the investigative unit. We are not in a position to confirm any further details of this active investigation.”
