Margaret Mick

Margaret Mick (1 June 1860 – 25 May 1925) was Canada's first female peace officer to be killed in the line of duty. On the night of Monday, May 25, 1925 Mick, who worked as a Matron, was the only staff member on duty at the Toronto Municipal Jail Farm for Women in Concord, Ontario. About 10:15 PM, one inmate was able to squeeze through the bars of her cell and free another. The two of them waited while a third complained about a leak in her cell. When Mick came to investigate she was jumped by the two lying in wait for her. She was beaten unconscious, and tied to pipes in a utility room. She was found dead the next morning still tied to the pipes.

The Farm was located in Richmond Hill on the north side of Highway 7 from Yonge Street to Bayview Avenue. The facility opened in 1912, was closed in 1959 and demolished in 1981. The surrounding land is now mixed commercial and residential development with no traces of the former facility.

Anton Martinsen Fladeby

Anton Fladeby came to Canada from Norway in the spring of 1909, a few of months prior to his 20th birthday and on December 1, 1914, at the age of 25, he enlisted as a guard at Manitoba Penitentiary (known today as the Stony Mountain Penitentiary). During World War I, he saw action overseas in France with the Canadian Army. In 1919, he returned to Canada and after a month of rest, returned to duty at Manitoba Penitentiary.

On Friday, May 2, 1919, ten days after his return to his work at the penitentiary, Fladeby was checking inmates in and out of the barbershop area when he encountered inmate Albert Johnson. Fladeby had recently searched Johnson’s cell and discovered a letter that the latter was writing, complaining about the ill treatment of inmates at Manitoba Penitentiary. Letters of this type were considered contraband at the time and Fladeby had confiscated it. Inmate Johnson now harboured strong resentment toward Fladeby.

Inmate Johnson lunged at Fladeby, stabbing him in the neck with a small knife he had gotten from the infirmary to "cut his fingernails", severing the artery on the right side. Two other inmates came to the aid of Fladeby and administered first aid until the arrival of the penitentiary doctor. Fladeby seemed to be resuscitating and was taken to the Winnipeg General Hospital. However, on Sunday, May 11, 1919, Anton Fladeby succumbed to his wounds. He was buried with full military honours in the "Field of Honour" at Brookside Cemetery in Winnipeg.

Albert Johnson was found guilty of manslaughter and received a life sentence, of which he served 16 years until his deportation to the United States.

John Williams

John Williams, a veteran of both the Boer War and World War I, became a guard with the Canadian Penitentiary Service on March 11, 1920. In the mid-1920s construction of a new sewage treatment plant began at the Stony Mountain Penitentiary (then called the Manitoba Penitentiary). On June 26, Williams was supervising an inmate work-gang blasting rock when a laid charge failed to detonate. Williams allowed an "inordinate amount of time" to pass before he removed the inmates to a safe area and investigated. Just as Williams reached the charge it detonated, killing him instantly.

Williams was buried with full military honours in the "Field of Honour" at Brookside Cemetery in Winnipeg. He was survived by his wife and four children.

Kearwood "Kip" White

Guard Kip White, a turnkey at the Huron County Gaol, was murdered in December, 1941. White was struck on the head with a hammer by an escaping inmate on 14 December, but did not immediately die. Shortly after, an x-ray showed that an abscess had formed on his brain, and on Christmas Day, White died on the operating table.
