Dennis Nilsen terrorized London in the late 70's and early 80's, killing 15 men over a five-year period. Nilsen would pick up young men at bars and take them back to his home. There, he'd strangle or drown them. Once dead, he'd bathe and dress the bodies, according to The International Business Times.

Nilsen became increasingly disturbed by his sexual encounters, which only seemed to reinforce his loneliness when they were over. He met his first young victim in a pub on December 29, 1978, and invited him home, as he had on previous occasions. The next morning, overcome by a desire to prevent the young man from leaving, he strangled him with a tie before drowning him in a bucket of water. Taking the corpse to his bathroom to wash it, he then placed it back in his bed, later remarking that he found the corpse beautiful. He attempted to have sex, unsuccessfully, then spent the night sleeping next to the dead man. He finally hid the corpse under his floorboards for seven months, before removing it and burning the decaying remains in his back garden.

Nilsen had another close call with the police in October 1979, when a young student accused Nilsen of trying to strangle him during a bondage-play session. Despite the student's claims, no charges were pressed against Nilsen.

Nilsen encountered his second victim, Canadian tourist Kenneth Ockendon, at a pub on December 3, 1979. Following a day of sightseeing and drinking, which ended at Nilsen's apartment, Nilsen again succumbed to his fears of abandonment and strangled Ockenden to death with an electrical cable. He cleaned up the corpse as he did before, and shared the bed with it overnight. He took photos, engaged in sex and finally deposited the corpse under the floorboards, removing it frequently and engaging in conversation, as if Ockenden were still alive.

His third victim, some five months later, was Martyn Duffey, a homeless sixteen year old, who he invited to spend the night on May 13, 1980. As with his first victim, Nilsen strangled then drowned him, before bringing him back to bed and masturbating over the teenager's corpse. Duffey was kept in a wardrobe for two weeks, before joining Ockenden under the floorboards.

His next victim was prostitute Billy Sutherland, 27, who had the misfortune of following Nilsen home one night. He too was strangled. Another one of his victims, 24-year-old Malcolm Barlow, was an orphan with learning disabilities, who was soon dispatched by strangulation.

By 1981, Nilsen had killed 12 men in the apartment, of whom only four could be identified. Given his penchant for preying on the homeless and the unemployed in a large city, this is probably less surprising than it might be in a smaller community.

He admitted to police that he kept the bodies for extended periods of time before disposing of them so that he could have sex with them and talk to them. He is currently serving a life sentence at the HMP Full Sutton prison in Yorkshire, England.

Lauria Bible and Ashley Freeman had been best friends since kindergarten. Lauria’s mom fondly recalls their friendship: “Lauria and Ashley would call each other at least once a week. What one was thinking, the other was thinking. It’s kind of like when two people—one can finish the sentence when the other one starts one.”

The two girls lived in a small town in rural Oklahoma; Ashley played basketball, and Lauria was a cheerleader. Ashley loved to hunt and fish. Lauria raised hogs to show at livestock competitions.

December 29, 1999 was Ashley’s 16th birthday, and the girls planned to celebrate with a sleepover at Ashley’s. After eating pizza at a local restaurant, Ashley, Lauria, and Ashley’s mother retreated to the Freemans' home.

Mere hours later, around 5:30 A.M., firefighters were summoned to the Freemans' mobile home. The whole trailer was engulfed in flames. After extinguishing the fire, the firefighters located the body of Kathy Freeman, Ashley’s mother. She had been laying near the bed, shot in the head before the fire started. Ashley’s father, Ashley, and Lauria were missing. The first theory: Danny had killed his wife, kidnapped Ashley and Lauria, and burned the home down to ruin any evidence.

This theory was quickly disproven. When Lauria’s parents came to the charred remains of the mobile home to search for a clue as to their daughter’s whereabouts, they discovered new evidence. What remained of Danny’s Rottweiler lay next to a pile of debris–and underneath was Danny Freeman's body. It was clear that Danny had been shot prior to the fire as well. With Danny’s body now located more questions arose. Where were the girls? Who shot the Freemans? Did the shooter take the girls?

The next discovery made by authorities was Lauria’s purse. Inside, they found her driver’s license and almost $200. Authorities drew two conclusions from this discovery. First, Lauria, in leaving behind her purse, likely did not leave the home willingly. Second, robbery seemed less plausible as the reason for the violence, as any thief would have taken the money.

Theories continued to abound. Danny was a rumored drug dealer. Perhaps the homicides had been a drug deal gone bad. Ashley and her father didn’t get along. Maybe the girls murdered Ashley’s parents and then fled. Yet none of the theories held up to scrutiny. All the authorities knew for sure: A couple was dead, and two girls were missing.

The local authorities launched a search for the teenagers. Nearby lakes, mine shafts, and quarries were searched to no avail. The search stretched far beyond Oklahoma's state lines, but to no avail. At least two convicted killers even confessed before recanting their statements. Soon, the case went cold.

Then, in 2017, nearly two decades after that fateful December night in Oklahoma, there was a break in the case. The Craig County Sheriff’s Department discovered a box of previously unknown notes and documents related to the investigation. The previous sheriff’s administration had reportedly stashed the documents. Among the cache were the names of witnesses and statements providing fresh leads. One of the most important pieces of evidence rediscovered was an insurance card found at the crime scene. The insurance card belonged to a woman who lived with a man named Phil Welch, who had borrowed her car around the time of the murders.

Phil Welch was a meth dealer with a criminal record. Investigators believed that Welch and two of his cronies–David Pennington and Ronnie Busick–visited the Freeman home that night about a drug deal. The confrontation grew heated; the men killed the Freemans. After killing the couple, the men abducted the girls and set the home on fire.

While Oklahoma law enforcement never recovered the photos, they had received reports of images; the three suspects were even on their radar. Yet there was never enough evidence to secure a conviction. The newly discovered cache—from the witness reports to the borrowed car and insurance card—was enough to pursue charges. 

Both Welch and Pennington had passed away before this major break. However, Ronnie Busick, now 66 years old, was still alive. In April 2018, he was arrested in Wichita and charged with four counts of murder.

John George Haigh was a British serial killer active in the late 40's. He used to dispose of his victims' bodies by burning them in sulfuric acid, according to Forensic magazine. Haigh was convinced he was getting away with murder, literally, because he mistakenly thought that without a body there was no crime.

Haigh was freed from prison in 1943 and became an accountant with an engineering firm. Soon after, by chance, he bumped into his former employer William McSwan in The Goat pub in Kensington. McSwan introduced Haigh to his parents, Donald and Amy. McSwan worked for them by collecting rents on their London properties, and Haigh became envious of his lifestyle. On 6 September 1944, McSwan disappeared. Haigh later admitted hitting him over the head after luring him into a basement at 79 Gloucester Road, London SW7. He then put McSwan's body into a 40-gallon drum and tipped concentrated sulphuric acid onto it. Two days later he returned to find that the body had become sludge, which he poured down a manhole.

He told McSwan's parents that their son had gone into hiding in Scotland to avoid being called up for military service. Haigh then took over McSwan's house and began collecting the rents for his parents, but he wanted the money from the properties. Donald and Amy became curious as to why their son had not returned as the war was coming to an end. On 2 July 1945, he lured them to Gloucester Road by telling them their son was back from Scotland for a surprise visit. He murdered them in his basement with blows to the head and disposed of them.Haigh then stole William McSwan's pension cheques and sold their properties, stealing about £8,000, then moved into the Onslow Court Hotel in Kensington.

Haigh was a gambler and by 1947 he was running short of money. To solve his financial troubles, he found another couple to kill and rob: Dr. Archibald Henderson and his wife Rose. After feigning interest in a house that they were selling, he was invited to the Hendersons' flat by Rose to play the piano for their housewarming party.

While at the flat Haigh stole Archibald Henderson's revolver, planning to use it in his next crime. Renting a small workshop at 2 Leopold Road, Crawley, Sussex, he moved acid and drums there from Gloucester Road. (Haigh was also known to have stayed at Crawley's George Hotel on several occasions.) On 12 February 1948, he drove Henderson to his workshop on the pretext of showing him an invention. When they arrived, Haigh shot Henderson in the head with the stolen revolver. He then lured Mrs. Henderson to the workshop, claiming that her husband had fallen ill, and shot her also.

After disposing of the Hendersons' bodies in oil drums filled with acid, he forged a letter from them and sold all of their possessions for £8,000, except for their car and dog, which he kept.

His arrogance is what ultimately got him caught when he led police to the remains of his sixth and final victim, 69-year-old Olive Durand-Deacon.

While on trial, Haigh pleaded insanity and insisted to the court that he drank the blood of his victims. He was found guilty in 1949 and hanged a few months later.
