one of the worst serial-killer cases in Canadian history.
A former nurse has pleaded guilty to first-degree murder in the deaths of eight nursing home residents in
Elizabeth Wettlaufer also pleaded guilty to four counts of attempted murder and two counts of aggravated assault.
The 49-year-old, who appeared in a Woodstock, Ontario, courtroom, admitted to killing eight seniors and hurting six others.
Wettlaufer acknowledged under questioning from the judge that she injected all 14 with insulin for no medical reason.
All the incidents allegedly occurred between 2007 and 2014 in three Ontario long-term care facilities where Wettlaufer worked as a registered nurse.
The prosecution read from an agreed statement of facts, saying that Wettlaufer told police she knew that "if your blood sugar goes low enough, you can die."
In at least one case, Wettlaufer was spurred to act by growing rage over her job and her life, which built up inside her until she felt an "urge to kill," the prosecution told the court.
Wettlaufer deliberately injected James Silcox, an 84-year-old man with diabetes and Alzheimer's disease, with insulin the night of August 11, 2007, "hoping he would die," the prosecution said.
"It was his time to go because of the way he acted," the former nurse told police, according to the agreed statement of facts.
She also told investigators that afterwards, she felt, "like a pressure had been relieved from me, like pressure had been relieved from my emotions.
Wettlaufer told police that dissatisfaction with her life led her to inject Clotilde Adriano, 87, with insulin, though Adriano survived.
The police investigation into Wettlaufer began last September after Toronto police became aware of information she had given to a psychiatric hospital in Toronto that caused them concern.

Friends and relatives of the seniors who died said earlier on Thursday that they were warned the hearing would reveal information that might be difficult for them to handle. Some, however, expressed relief that the case would come to a swift conclusion.
