He went on to later brag about his killings and even gave his detective friend a tour of where the murders took place. He was arrested and charged for the murders of four women, attempted murder for another, and extortion of two London physicians. A jury met in 1892, and it took them less than 10 minutes to convict him; he was sentenced to the gallows.

Day job: Medical practitioner.

Even though she had very little training and no medical degree, Linda Hazzard was certified by Washington state as a "fasting specialist" and referred to as Dr. Linda Hazzard. She published a book titled Fasting for the Cure of Disease, where she stated her beliefs of food being the root of all diseases, especially eating too much of it. She only allowed her patients to consume small amounts of vegetable broth, if anything. In 1908, one patient died after fasting for over 50 days in Hazzard's care. Hazzard targeted wealthy patients, many of which signed over large portions of their estates to her before their eventual deaths. 

In August 1911, Hazzard was arrested for first degree murder for starving Claire Williamson, one of her very wealthy patients, to death. She never took responsibility for starving any of her patients, but a jury found her guilty of manslaughter and sentenced her to two years of hard labor in a penitentiary. While her state medical license was revoked, the governor had pardoned her. In 1920, she built a sanitarium and called it the “school for health.” It's estimated that Hazzard starved over a dozen people to death.

Despite being fired at many practices for forging prescriptions, Shipman was never removed from the General Medical Council and continued acquiring dangerous amounts of diamorphine. He'd administer a lethal dose of diamorphine and either watch his patients die right in front of him or send them home to perish. He always targeted the most vulnerable, as his oldest victim was 93 years old and the youngest was 41. 

While there were many suspicions in the community, Shipman wasn't caught until he forged the will of one of his patients. In 2000, Shipman was given life in prison. In January 2004, he had taken his life in his jail cell. While police could only charge Shipman with 15 murders, it’s been estimated that his victim count is anywhere between 250 and 450.

He was caught tampering with an IV and wasn't allowed to complete his neurosurgery residency. He later went to prison for five years for attempting to poison colleagues from his next job as a paramedic and had his medical license suspended. 

Once he was released, he entered a residency in internal medicine in South Dakota using forged documents. He even landed a spot at Health Science School for Medicine at Stony Brook University and traveled to a local medical center for training. When he was eventually fired from here, Swango moved to Zimbabwe to work at a small village hospital for three years. By the time he returned to the states in 2000, a case had been built around him of suspicions from a coworker, and he was charged with three counts of murder. Traces of epinephrine, which temporarily speeds up the heart to deadly rates, and succinylcholine, which can cause paralysis, was found in deceased patients' organs. Swango pled guilty and received three consecutive life sentences without the possibility of parole. It's estimated he killed over 60 people, including patients from his time in Zimbabwe.

Day jobs: Doctor, French Army member, and mayor

After being discharged from the French army during World War I for abnormal behavior, Mercel Petiot enrolled in school and earned a medical degree in 1921. He was even elected mayor in 1926, but had his title suspended for a couple months in 1930 after being convicted of fraud. It was around this time when one of his patients mysteriously died, and then another patient, who accused him of the first victim's death, died as well. 

He moved to Paris in 1933 to continue his crimes, as he lost his council seat when he was convicted of stealing electricity. In Paris, Petiot preyed on Jewish people fleeing from France during World War II, as he offered them help and promises of medicine, but he was really injecting them with poison. Once they died soon after his injections, he stole their money and valuables. After the liberation of France came in 1944, Petiot was arrested and charged with 27 murders. He was convicted of 26 murders, but he confessed to over 60 murders at trial and stated that the bodies found were Nazis who were killed by the French Resistance. Petiot was guillotined in 1946.

She set up meetings for alcoholics, people with no homes, people with mental distresses, people with disabilities, and elderly people. She often let these people live in the house and set up their Social Security checks she would collect when they eventually died.

The people under Puente's care were often drugged to death and died of pain medication overdoses given by Puente. Due to her elderly and frail appearance, police did not take claims suspecting her serious. She fled to Los Angeles once bodies were found in her backyard, but was later sent back to Sacramento and charged with nine counts of murder. She was only convicted of three murders and was sentenced to life without parole, though she soon died in prison at the age of 82.

Day jobs: USPS letter sorter and former military member

David Berkowitz joined the US Army at age 18 and served in South Korea as a skilled marksman. After his service, he returned back to his native New York and was employed by USPS as a letter sorter. It was two years after this where he started his killing spree in July 1976. It wasn't until nearly a year on the dot later he was caught after a witness of his last shooting noticed a car with a parking ticket that could've only belonged to Berkowitz. 

According to the New York Times, Berkowitz told police, "Well, you've got me," when he was finally arrested. Upon his arrest, he told police that his neighbor's dog, Sam, was possessed by a demon and told him to commit the murders. While no one believed it at the time, he wrote in a letter to a psychiatrist after his conviction that it was a ploy and “it was all a hoax, a silly hoax." In 1978, Berkowitz pled guilty to six murders and setting 1,500 fires around New York City. He received a 25-year sentence for each count of murder and is currently still serving his sentence.

Day job: Pig farmer

Robert Pickton was a pig farmer on a remote farm he owned and operated in Vancouver, British Columbia. Pickton and his brother started a nonprofit in 1996 called the Piggy Palace Good Times Society with the goal to “organize, coordinate, manage, and operate special events, functions, dances, shows, and exhibitions on behalf of service organizations, sports organizations, and other worthy groups.” These events they organized were raves set in the slaughterhouse and brought in crowds of up to 2,000 people. While Pickton was suspected of being the cause for many missing women in the area and even briefly went to prison for attempted murder, it wasn't until 2002 when police searched his farm. 

Investigators found DNA and remains matching 26 missing women on the property, as he would often take their bodies to a nearby meat rendering plant or feed them to the pigs. While he was charged with 26 murders, he was only convicted of six counts of second-degree murder. He was sentenced to life in prison without the possibility of parole for 25 years, which is the maximum sentence for a second-degree murder charge in Canada. Pickton admitted to 49 murders, but no other charges were added, as he was already receiving the maximum.

Day job: Candy factory owner

Dean Corll was known to pass out candies to local children from the candy factory his family owned. But between 1970 and 1973, he would torture and kill boys and young men inside his various rental houses and apartments in Houston. Corll recruited the help of Elmer Wayne Henley Jr. and David Owen Brooks to lure these victims into their van with the promises of rides and parties. Their killing spree ended in 1973 only because Henley shot Corll during the attempted sexual assault of a victim. When police arrived to the scene, the 17-year-old Henley confessed to the 28 murders, six of which he committed, and led them to the remains. Henley was convicted of six counts of murder and his role in the killings. He received six consecutive 99-year sentences.

Day job: Second-year medical student

Philip Markoff was a medical student at The State University of New York at Albany pursuing a career toward becoming a doctor. On April 13, 2009, Markoff responded to a Craigslist ad from Julissa Brisman, a masseuse and aspiring model. The scene where Brisman was found after meeting with Markoff seemed to be a robbery gone wrong where she was left severely injured and died a week later in the hospital where he studied at.

He planned and carried out two other violent attacks through Craigslist, until his digital footprint caught up to him. Police were able to track him through messages from email providers and IP addresses. When policed searched his apartment, they found bullets, cash, plastic ties, women’s underwear, and a hard drive containing the messages from Craigslist. Markoff pleaded guilty to Brisman's murder within 48 hours of being taken to jail and was put on suicide watch. But in August 2010, he committed suicide in jail.

Day job: ADT alarm installer

Dennis Rader was employed as an ADT security alarm installer from 1974 to 1988 in the Wichita area. His community viewed him as a leader through his local church and Cub Scouts program. He even had children and raised a family during this time, which was also the period in which he started his killing spree. From 1974 to 1991, he killed at least 10 people who he usually targeted from visiting their homes while installing alarms. 

When he paused his killing spree, police still had no leads so they wanted to bait the murderer. Their efforts worked, and it angered Rader that someone else could possibly receive the credit for his killings, so he sent in a floppy disc proving they've been misled. Police quickly connected the disc to his church and found it came from someone named Dennis. In 2005, Rader was arrested and later found guilty on 10 counts of murder. He received 10 consecutive life sentences, and currently, his earliest release date is set to be in 2180.
