Martha Wise, often referred to as the "Poison Widow of Hardscrabble," was an American serial killer from Ohio who was active in the 1920s. She poisoned 17 of her family members, which resulted in three deaths and 14 injuries. Her weapon of choice was arsenic, which she administered through water buckets and coffee pots.
In March 1925, after confessing to authorities who had become suspicious of her large purchases of arsenic, Martha was arrested and charged with first-degree murder. She was sentenced to life imprisonment.In 1962, after serving 37 years in prison, Martha had her sentence commuted to second-degree murder due to her good behavior. However, no family members would take her in, and rest homes refused to accept her. Within three days, she returned to prison, where her parole was revoked. Martha died in the Ohio Reformatory for Women on June 28, 1971, at the age of 88.
Karla Homolka, a serial killer who acted as an accomplice with her husband Paul Bernardo (also a serial killer) in the rapes and murders of at least three teenagers, including her own sister from 1990–1992.
According to CBC News, "Bernardo was convicted in 1995 of the kidnapping, raping, and murdering of southern Ontario teenagers Kristen French and Leslie Mahaffy. Homolka portrayed herself as the innocent victim of a murderous monster. She struck a deal with prosecutors (later dubbed the "deal with the devil") and pleaded guilty to manslaughter in the deaths in exchange for a 12-year prison sentence. But videotapes of the crimes, found after the plea bargain, showed her to be a more active participant. Public outrage about Homolka's sentence had barely cooled by the time of her extremely high-profile release from prison in 2005."

Bob Kelley of the Volusia County Sheriff's Department — who investigated the case — later said, "After she was convicted of the first murder of Richard Mallory, she then pled guilty to the others, and after a certain point in time she started to recant and say she wasn't a victim.

Fellow Norwegian Americans flocked to her property — hoping for a taste of home along with a solid business opportunity. She also posted ads in lovelorn columns to attract wealthy bachelors. To lure her last victim, Gunness wrote: 'My heart beats in wild rapture for you, My Andrew, I love you. Come prepared to stay forever.'"

According to National Geographic, "Some witnesses estimated her body count at more than 600. Yet the countess was never convicted, and her husband could not be prosecuted from his grave.

The countess, meanwhile, remained locked in her spacious jail until she died in 1614, at the age of 54."

In 1869 she began advertising in local papers — 'Married couple with no family would adopt healthy child, nice country home. Terms - £10.' But instead of providing a safe and loving home, she would instead take the child for a fee and murder them — either by starving them, drugging them with an opiate-laced cordial known as Mother's Friend, or by strangulation."
