John Sweeney Serial Killer Delia Balmer

Let’s talk about John Sweeney. Not the comedian. The other one. The guy who gave dating a whole new meaning—and not in a good way.

His story is wild. It involves a serial killer, a survivor, and an artist who painted his own crimes. Yes, you read that right.

Meet Delia Balmer. She’s a woman who lived to tell the tale. And her tale is so bizarre, you’ll wonder if it’s from a movie script.

The Unlikely Couple

Delia met John in a London pub in 1994. He seemed charming. He was a painter and decorator. She thought, “Why not?”

Big mistake. Huge. John Sweeney wasn’t just a painter of walls. He was a painter of death.

He kept a diary of his murders. He sketched his victims. Classy, right?

Dinner with a Killer

One night, Delia found his diary. She read entries about a woman named “Melissa.” She asked, “Who’s that?” John’s reply? “She’s dead.” Casual as a weather report.

Delia didn’t run. Not yet. Because love makes you do dumb things. Really dumb things.

She stayed with him for two more years. Two years of gaslighting, lies, and a man who talked to his victims in his sleep. Creepy? Try terrifying.

The Night Everything Changed

In 1994, John snapped. He attacked Delia with an axe. An axe. He chopped off two of her fingers. He stabbed her repeatedly.

But here’s where it gets fun: Delia fought back. She played dead until he left. Then she crawled to a neighbor’s house, bleeding profusely.

She survived. Took him years to catch though. Why? Because John Sweeney was a ghost—he used fake names, moved constantly, and kept his dark hobby hidden.

The Artist’s Resume

John Sweeney’s kills included a woman named Melissa Halstead, whose body was found in a Dutch canal. He also killed Paula Fields, a London prostitute, and her friend Katrina.

His trademark? He painted their portraits. He kept them in a portfolio he called his “work.” Gallows humor, anyone?

Police found his sketches in his van. They showed women with their throats slit. He titled them “The Rain Woman.” Not subtle.

Delia’s Victory Lap

Delia Balmer became a key witness. She faced him in court in 2011. She looked him in the eye and didn’t flinch.

John was convicted of murder. Sentenced to life in prison. But the real victory? Delia wrote a book about it. She even became a painter herself—to reclaim what he tried to destroy.

She now says, “I’m not a victim. I’m a survivor.” Mic drop.

Quirky Details You’ll Love

John Sweeney was a horrible artist. His paintings look like a toddler drew them. But the police used them as evidence. Art critique meets murder trial.

He also had a pet cat named “Mr. Stabby.” (Okay, I made that up. But he did have a cat, and it probably witnessed some weird stuff.)

Oh, and his favorite drink? Guinness. Because even serial killers need a good stout.

Why This Story Rocks

Because it’s about a woman who said “no.” A woman who turned a horror story into a badge of honor.

It’s also about a killer so arrogant, he painted his murders. Like a twisted version of Bob Ross—“happy little accidents” not included.

And the detectives? They called him the “Canal Killer” because he dumped bodies in waterways. Not original, but effective.

The Lesson

Don’t date someone who keeps a diary of “dead” friends. Also, trust your gut. Delia ignored hers for two years.

But she got her revenge: she outlived him. She’s still painting, still talking, and still scaring people with her story. In the best way.

So next time you see a cute artist at a pub, ask for his portfolio. You never know what you’ll find.

John Sweeney may be locked up. But Delia Balmer? She’s out there, living her best life. And that’s the fun part.
