Ontario Provincial Police have been asked to examine two additional deaths at long-term care facilities where a nurse accused of murdering patients previously worked.

London-based lawyer William Brennan confirmed the information to CTV News Thursday. It’s unclear where the additional alleged deaths took place.

The allegations stem from an investigation involving a former Ontario nurse, Elizabeth Tracy Mae Wettlaufer, who is accused of murdering eight elderly long-term care patients in Woodstock and London.

Wettlaufer, 49, appeared via video link in a Woodstock courtroom Thursday morning. .

Wettlaufer was charged in September with eight counts of first-degree murder in connection with the deaths of patients at the Caressant Care facility in Woodstock and the Meadow Park long-term care home in London.

The patients ranged in age from 75 to 96 and police allege that they died after being administered a drug.

The deaths occurred between 2007 and 2014.

Seven of the alleged victims were patients at the Woodstock facility and one was a patient at Meadow Park in London.

Donald Martin told CTV News Toronto that he decided to attend the courthouse Thursday on behalf of his friend Maurice “Mo” Granat, who was 84 years old when he died at Caressant Care. Granat is one of the eight nursing home residents named in connection with the murder investigation.

Martin says he encountered Wetlauffer while visiting Grant and was called to the nursing home the night he died.

“When we arrived in the room she was in the room at that point and he was having quite a struggle,” Martin said. “He was flailing his hands and weird noises coming out of him. They’re not good memories.”

Martin alleges that he witnessed Wettlaufer gave Granat “an injection” the night he died.

“As soon as I arrived, I said ‘it’s alright Mo’ and he calmed down. She left the room and then about 20 minutes later, she came back in. (That’s when) she gave him an injection. She walked over to the side of the bed, gave him an injection and said this will soothe him,” Martin said.

“About 20 to 25 minutes later, he passed away.”

None of the allegations have been proven in court.

The case has been put over until January 6, 2017.
