Elizabeth Wettlaufer confessed to attacking a 15th patient. The public was never told

At least three Ontario police services were aware that serial killer Elizabeth Wettlaufer confessed to attacking a fifteenth elderly patient, yet the crime was withheld from the public and was never disclosed during a multi-million-dollar public inquiry looking into Wettlaufer's crimesand why they went undetected for so long.

CBC News has obtained a partially redacted police report written by the London Police Service, outlining how Wettlaufer confessed on numerous occasions to injecting Florence Beedall, 77, with insulin. The attack happened in August 2014 at theMeadow Park care facility in London, Ont.

Wettlaufer, whoisservingeight concurrent life sentences for the murders of eight patientsin her care,was working as a nurse there.

Beedall was a palliative-care patientand Wettlaufer injected her with two units of the drugin "an effort to let her go quicker," according to the police report.

Beedall was not a diabetic, and there was no medical or legal reason for Wettlaufer to administer insulin to her, according to the police report.

Beedall was in the final stages of lifewhen Wettlaufer injected her with the insulin, police learned. Beedall died about an hour later.

A local coroner ruled the death was the result of complications from dementia and hypertension.

The police report, written by veteran London Police Det.Steven Simone, reveals police determined: "Ms. Wettlaufer did commit the offence of Assault with a Weapon." Police then determined"that no criminal charges be laid in this matter despite having grounds to proceed."

The report also cites concerns Beedall's family had about possible charges leading to unwanted publicity.

Police quietly obtained the first confession a year ago

The report reveals police first obtained Wettlaufer's confession during a jailhouse interview at Kitchener's Grand Valley Institution for Womenin January 2018. She was interviewed by Woodstock, Ont., policewho were deeply involved in the Wettlaufer probe.

Months later, Wettlaufer was transferred to a Montreal facility where she again provided information about the attack on Beedall, according to the police report.

CBC News has learnedthat at one point, police took a photo of Beedall to Wettlaufer, to ensure Wettlaufer was confessing to attacking her.

In March2018, police also obtained a court order to seize Beedall's medical records from Meadow Park.

OPP originally denied knowledge of confession

CBC News first became aware of the allegations two months ago, and reached out to Ontario Provincial Police, the lead agency in the Wettlaufer probe.

At the time, the OPP denied Wettlaufer had admitted to killing Beedall. They now concede they were aware that Wettlaufer had admitted to harming her.

Asked why no charges were laid, OPP Staff Sgt. Carole Dionne told CBC Newsthere was no point given Wettlaufer is already serving a life sentence for her many other crimes against patients.

"We consulted with the attorney general and it was determined it was not in the public interest."

Dionnesaidthe OPP disclosed the confession to thepublic inquiry.

"Everything that pertained to this investigation was disclosed. That would include Ms.Beedall," said Dionne.

Beedall not mentioned at inquiry

Since June, a public inquiry looking into Wettlaufer's crimes has been examining how they went undetected for almost a decade until Wettlaufer's confession to police in 2016.

Dozens of witnesses testified, yet there was never any mention of Beedall.

The inquiry is now in its final stage, preparing recommendations aimed at preventing a similar situation from happening again.

Mark Zigler, lead co-counsel for the inquiry, saidon Wednesday he's never seen the police report.

"I don't know if there's anything the inquiry can do until somebody presents us with something and asks us to do something about it at this stage," he said.

Alex Van Kralingen, a lawyer representing the families of some of Wettlaufer's other victims at the inquiry, saidthe existence of the confession would have been important information to have.

"I have difficulty believing the inquiry was made aware of it. The idea that issue would not have been canvassed strikes me as very unusual. It doesn't add up to me," said Van Kralingen.

Beedall's family has declined to speak about the situation.

Wettlaufer confessed to injectingArpad Horvath, 75, with lethal amounts of insulin at Meadow Park on the same day Beedall died.

Wettlaufer told police she felt a "red surge" of anger before attacking the previously identified 14 victims.

The former nurse has also confessed to lethally injecting seven residents at the Caressant Care home in nearby Woodstock, Ont.: James Silcox, 84, Maurice (Moe) Granat, 84, Gladys Millard, 87, Helen Matheson, 95, Mary Zurawinski, 96, Helen Young, 90, and Maureen Pickering, 79.

She's also admitted to trying to kill or harm six other patients in her care with insulin injections.
