Mary Clement
Serial Poisoner Case
CLASSIFICATION: Serial Homicide
LOCATION
Dubuque, Iowa
TIME PERIOD
1880-1885
VICTIMS
4 confirmed
Mary Clement, a Luxembourgish-born American, is implicated in a series of poisonings that resulted in the deaths of her immediate family members in Dubuque, Iowa, between 1880 and 1885. The victims included her younger sister Annie, her parents Margarite and Michel, and her sister Lena, all of whom died under suspicious circumstances attributed to convulsions or heart failure. Following these deaths, Clement moved to Rose Hill, Illinois, where she attempted to poison her sister Catherine's family, leading to her conviction for attempted murder in June 1885 and a subsequent one-year sentence at Joliet Prison. Significant evidence included a grayish powder found in the family’s food, which was linked to the violent illnesses experienced by the Freres family, raising suspicions that ultimately led to her apprehension.
Mary Clement is believed to have poisoned her family members, including her parents and two sisters, with many theorizing that her motive was financial gain or a desire to eliminate those who might hinder her independence. There is speculation that her actions were influenced by her difficult upbringing and her physical disabilities, leading to feelings of resentment and a need for control. Additionally, some theorists suggest that her later attempt to poison her sister's family indicates a pattern of behavior that persisted despite her initial lack of consequences for the earlier deaths.
The Tale of Mary Clement: A Serial Poisoner's Hidden Life
A Quiet Beginning
In the small village of Harlange, nestled in the Luxembourg countryside, Mary Clement was born on February 16, 1863. The second of five daughters to Michel and Margarite Clément, young Mary lived a life that seemed ordinary at first glance. But in 1871, the Cléments sought new beginnings in the United States, eventually settling in Dubuque, Iowa. By 1874, the family had grown with the birth of their youngest daughter, Annie. Despite her slender and pretty appearance, Mary carried a hidden defect—a spinal abnormality that left her with only partial control over her legs and feet.
A Series of Suspicious Deaths
The tranquility of the Clément household shattered in 1880 when Annie, at just six years old, succumbed to violent convulsions. Her untimely death was initially blamed on overindulgence in food before bedtime. Yet, the shadow of death loomed large over the family, as over the next few years, similar fates befell her parents and sister Lena. Each passed away under mysterious circumstances, wracked by convulsions or heart failure after enduring an unidentifiable illness. The victims were:
- Annie, aged 6, died on August 1, 1880.
- Margarite, aged 54, died on July 24, 1884.
- Lena, aged 13, died on August 9, 1884.
- Michel, aged 49, died on March 28, 1885.
The Freres Family's Ordeal
Two months after burying her father, Mary moved to Rose Hill, Illinois, to live with her sister Catherine, her husband Michael Freres, and their two children. Mary often cooked for the family, but her meals left a bitter taste—literally. Each serving brought bouts of violent vomiting and spasms. Michael Freres' suspicions grew as he noticed that Mary never touched the soup she served.
One afternoon, Michael discovered a packet of grayish powder in the backyard. After another bout of sickness from eating soup, he realized the sediment in his plate matched the powder. Further inspection revealed more of the substance in his family's plates. Alarmed, Michael took the powder and plates to Evanston for analysis. Dr. Isaac Poole and Professor H. S. Corbart confirmed his worst fears—the powder was arsenic. Mary's arrest followed swiftly.
Trial and Confession
Behind bars, Mary Clement initially protested her innocence with fervor, weeping for two days. She claimed her sister falsely accused her to steal $100 she supposedly possessed. Yet, when pressed by a reporter, Mary confessed not only to poisoning the Freres family but also to the murders of her parents and sister. She described a compulsion to end her ailing mother's suffering, which she extended to her sister and father. Money, she insisted, was not her motive; she despised it, spending it quickly to rid herself of its presence. Her confession spiraled into hysteria, culminating in her demanding a priest.
During a subsequent interview with Dr. Bluthardt, Mary denied any recollection of her confession. Although Bluthardt dismissed the notion of insanity, he noted her extreme nervousness and sensitivity. Throughout her trial, Mary maintained an eerie calm, sparking media commentary on her demeanor. Despite her composed exterior, the evidence and Michael Freres' testimony sealed her fate. The jury sentenced her to a year in Joliet Prison. In a letter penned a month later, Mary reiterated her guilt, even confessing to Annie's murder, shocking those who had believed her innocent. She expressed satisfaction with her short sentence.
Life After Prison
Upon her release, Mary Clement moved to Los Angeles, where she became a domestic servant for a wealthy family. Known for her elaborate hats and reticence about her past, she lived out her days as a seemingly benign figure. Mary Clement died on July 9, 1944, at the age of 81. Her final resting place is the Freres family plot at St. Henry's Church in Chicago, a macabre closure to her life of hidden darkness.
