5 things nurse Elizabeth Wettlaufer suggests might have stopped her killing

A public inquiry into the state of long-term care in Ontario has been ongoing since June to determine how Elizabeth Wettlaufer was able to murder eight patients in her care and what can be done to prevent similar crimes in the future. Before the inquiry began, the ex-nurse was asked what she thinks could have stopped or slowed her killing spree.

"I've given a lot of thought to changes that could have been made where I would not have been able to do this."

That's what Elizabeth Wettlaufer told three lawyers taking part in the Long-Term Care Homes Public Inquiry. The attorneys spoke with the serial killer nurse prior to the start of the inquiry, which began in June at the Elgin County Courthouse in St. Thomas, Ont., and has continued throughout the summer. 

The inquiry was called after Wettlaufer was convicted of eight counts of first-degree murder, four counts of attempted murder and two counts of aggravated assault; offences she committed while working as a registered nurse in long-term care homes in Ontario. She is now serving eight concurrent life sentences at the Grand Valley Institute for Women in Kitchener, Ont.

In the lead-up to the inquiry, lawyers went to the prison on Feb. 14, 2018. For two hours, they spoke with Wettlaufer, who chose not to have a lawyer present. One of the questions she was asked was what she thinks could have stopped, or reduced, her killing spree?

Here's some of what she told them, based on a transcript of the meeting entered into evidence at the inquiry: 

1. Controls on insulin

Wettlaufer killed patients in her care by injecting them with massive amounts of insulin. She chose insulin because it wasn't tracked the same way narcotics are tracked, she told the lawyers. 

"It wasn't counted and I knew that was something that could kill people. The lack of following up on insulin is what made it available to me," she said. 

Insulin is administered using pen-like devices into which a nurse puts a cartridge filled with insulin. To deliver a specific dosage, a nurse "dials up" the amount of insulin and then injects a patient. Sometimes, another nurse had to check that the "dialed up" dosage matched the dosage prescribed to a resident.

"There's 120 units [of insulin] per cartridge, but if I dialled up 15, I could leave the nurses station and take out the insulin pen and dial up another 50," Wettlaufer said. "There's no control over that." 

Boxes of cartridges are labelled with patient names, but not the cartridges themselves. Wettlaufer said there was always at least one pen that wasn't being used that she could use to overdose her victims. She said she sometimes told patients she was giving them vitamins. 

Pharmacies never questioned why more insulin was being used than was being prescribed — something that would have immediately raised red flags if she had used a controlled substance like an opioid. 

"There was never a time when it was questioned why we were at times going through more insulin than others. Insulin is not counted the same way narcotics are," she said.

Wettlaufer said a stop-gap on the cartridges preventing nurses from delivering more than the prescribed dose, or pens pre-loaded with only the amount of insulin needed for a particular patient would have prevented her from using it to overdose people in her care. 

"If there was a way that the insulin was counted I would not have been able to do what I did without getting caught," she told the lawyers.

Nurses from the Caressant Care home in Woodstock, Ont., where Wettlaufer killed seven of her eight victims, testified at the inquiry that they now check when a nurse dials up insulin right before it is administered, but that the practice is time-consuming. 

2. Medication room oversight

Insulin and other drugs are kept in medication rooms in long-term care facilities. At the homes where she worked, Wettlaufer said there was no way to see into the rooms to check if something nefarious was going on. 

"If the med room was completely made of glass, there's no way I could have done what I did without somebody seeing me," Wettlaufer said, though she admitted she could have "dialed up" more insulin elsewhere. 

"Even if there had been a window in the med room I could still have taken the insulin and gone somewhere else to dial up, because it's just pens that you pick up and put in the med cart and sometimes I'd just stick it in my pocket." 

At Caressant Care, managers told staff that security cameras were going to be installed after opioids went missing in 2013. But they were never installed, the inquiry heard. 

Wettlaufer called the med room at Geraldton General Hospital, where she worked as a student nurse before stealing drugs and overdosing, "a nightmare." At the time, she stole Ativan (Lorazepam), a benzodiazepine which was not a controlled substance. 

3. Mental health check-ins

Wettlaufer had a history of mental illness and substance abuse, and was fired from her first nursing job at Geradlton General Hospital in 1996 after stealing Ativan and overdosing. It was not her only suicide attempt. 

From 2006 until 2017, during the span of her murders, Wettlaufer saw the same psychiatrist every month. He prescribed her two major drugs, one for obsessive compulsive disorder and depression, and the other an anti-psychotic. It was only after she was taken off the anti-psychotic in prison that she realized the gravity of what she'd done, Wettlaufer told lawyers. 

'I knew the difference between right and wrong': Elizabeth Wettlaufer

"My head is so much clearer. My emotions are so much clearer. I have so much more remorse for my crime now than I did when I was on Seroquel," she said. 

She said that she didn't like her psychiatrist and he wouldn't probe during their visits. He would ask how she was doing, and she would answer "fine," and then walk out with a refill for her medication. 

Wettlaufer went from working in a group home, where there were three staffers for five residents, to working alone as a nurse in charge of almost 100 residents at night and 32 during the day. She frequently worked double shifts which lasted from 3 p.m. until 7 a.m. the next day. 

"It was busy. Initially I kept up with it, but it was really busy. I don't think I managed it well, but I managed it. I certainly didn't enjoy it," she said. 

Wettlaufer said she had thoughts of killing her psychiatrist and people she worked with. She said she coped by putting those thoughts into a different part of her mind, adding that stress at home added to the problems. 

"When I got to Caressant Care, it got to the point fairly quickly that I was finding it hard to handle things emotionally, with being [at work] and with all the workload and having my partner living with me and her two kids." 

To relieve the pressure, she said she tried to kill two patients "just to see what happens." 

The inquiry has heard the long-term care sector is always short-staffed and registered nurses are often asked to work long overtime shifts. 

4. An advocate for dementia patients

"Every patient I ever picked had some dementia and that was part of what became my criteria. If they had dementia, they couldn't report or if they reported, they wouldn't have been believed," Wettlaufer told the lawyers. 

"Anybody I ever did had dementia. That was part of the not getting caught." 

Doctors and administrators also seemed unconcerned about "sudden and unexpected" patient deaths, which are supposed to trigger automatic coroner reviews. 

"We were told, 'No, if they're in a nursing home they need care, and their death isn't unexpected,'" Wettlaufer said. 

5. No action on confessions

After she killed her first two victims in 2007, Wettlaufer told her girlfriend about what she'd done. 

"She didn't do or say anything about it. She just said, 'Well, you need to stop doing that. Don't do it anymore because you don't want to get caught.' But I don't know if she actually believed me," Wettlaufer told the lawyers. 

She confessed again in 2011 to a teenager who worked shifts at Caressant Care. 

In 2014, she confessed to her pastor and his wife, then later that year she told an ex-boyfriend. 

Elizabeth Wettlaufer's colleague called her 'an Angel of Death'

"He said, 'Why don't you change your job so that you don't have the opportunity. Why don't you stop being a nurse, come live with me, I'll leave my wife and look after you,'" Wettlaufer said.  

She told a lawyer in 2014, after a stint in a treatment facility after stealing hydromorphone from the Meadow Park home in London, Ont., and overdosing, and she told her Narcotics Anonymous sponsor that same year. 

"She just kind of laughed about it, so I don't think she believed me," Wettlaufer said. 

After checking herself in to the Centre for Addiction and Mental Health in Toronto in 2016, she told someone who she had worked with at Caressant Care. 

"She said, 'You better go and turn yourself in. If I hear that you haven't, I'm going to call the police.'"

Wettlaufer did turn herself in to police.
