Florencio Fernández

Florencio was a serial killer in Argentina throughout the 1950’s. It is believed he murdered around 15 women in the own of Monteros. He was most popularly known as “The Argentine Vampire” or “The Window Vampire.” Florencio was believed to have been mentally ill and suffered from many delusions that had him convinced he was a vampire. He also had a strong sexual attraction to blood. He was abandoned by his family at a young age which forced him to live on the streets.

Florencio would stalk his victims for a short period of time, usually less than a week, and when they were home alone he would sneak in through open windows during hot summer nights. He would beat his victims, bite them (on occasion he would cut open the trachea and carotid) and drink the victim’s blood. Most of the time if the victim survived the attack he would leave them to bleed out.

Florencio was arrested in February of 1960 at the young age of 25. He only resisted arrested when the police forced him out of his cave and into the sunlight. Florencio was pronounced mentally insane and sent to die in a psychiatric facility.

Kathleen Folbigg

Kathleen Folbigg is a convicted serial child killer in Australia. She was convicted of murdering four infant children. All four murders occurred between 1989 and 1999. Her killing spree was brought to an end when her spouse found her diary which had details and admissions of guilt on the killings.

Originally Folbigg was sentenced to 40 years imprisonment with a chance of parole after 30 years. She appealed her case and was given a shorter sentence of 30 years imprisonment with a chance of parole after 25 years. Folbigg’s trial lasted nearly two months. The prosecution weaved the story that Folbigg killed her children by smothering them, claiming that it was during times of extreme frustration for the accused.

Folbigg’s defense argued that she did no harm to her kids and that nobody believed her husband was responsible for the crimes either. They also posed natural causes for the deaths such as cot death and myocarditis. There were never direct admissions of murdering the children in her personal diary, only admissions of guilt that the defense suggested was a typical mother’s guilt to the death of her children. Even with no physical evidence to the crimes she was convicted of the murders based on circumstantial evidence.

Elizabeth Tracy Mae Wettlaufer

Elizabeth is a serial killer and former registered nurse from the country of Canada. She confessed to the murder of eight senior citizens, and the attempted murder of an additional six in Southwestern Ontario. The events took place between 2007 and 2016.

Elizabeth worked as a nurse at Caressant Care. While employed she began injecting patients with insulin. In several of the cases, it was a minimum amount and not enough to kill the patients. For these cases, she was charged with attempted murder and aggravated assault. Wettlaufer’s first kill occurred on August 11, 2007. The victim was James Silcos, an 84-year-old WWII veteran, and father of six children. Elizabeth injected the senior with enough insulin to kill him.

On September 16, 2016, Elizabeth entered into an inpatient drug rehab program at the Centre for Addiction and Mental Health in Toronto. It was there she confessed to the staff about her attempted and confirmed murders. The staff then notified the Toronto Police of her confession and later she emailed the College of Nurses to officially resign as a registered nurse stating she had “deliberately harmed patients in care and now being investigated by the police for the same.” The CAMH staff faxed a four-page handwritten confession to officials.
