Elizabeth Wettlaufer pleads guilty to 8 counts of murder

A former Ontario nurse angry with her career and personal life believed she was an instrument of God as she used insulin to kill vulnerable seniors in her care over the course of nearly a decade.

About seven months after her arrest last fall, Elizabeth Wettlaufer pleaded guilty Thursday to eight counts of first-degree murder, four counts of attempted murder and two counts of aggravated assault.

The crimes -- which took place in three Ontario long-term care facilities and at a private home -- make Wettlaufer one of Canada's most prolific serial killers.
