Most people download tutoring apps to learn a language or prepare for exams.

Jung Yoo-jung downloaded one to find a victim.

(And after learning about this case... we are side-eyeing every tutoring app on the planet 😭)

In 2023, the 23-year-old South Korean woman decided she wanted to cross one specific item off her bucket list.

falling in love.

getting a degree.

traveling the world.

Murder.

When police later asked her why, her response was terrifyingly casual:

"I just wanted to know what it feels like to kill."

(The girl literally treated homicide like a weekend DIY project. 🚩)

She made a fake profile on a popular tutoring app, posing as a frantic mother looking for an English tutor for her middle-school daughter.

Here’s the wild part: the app ran thorough background checks, identity verification, and degree checks on every tutor.

You know who they didn't check? The parents 💅🏻

One tutor turned her down because of the distance. Normal people would take the L and move on. 

Jung replied: "Don't worry, I'll bring my daughter to you."

The tutor, a young woman named Hannah, felt bad for the "struggling mom" and agreed (this is what saying yes can cost you sometimes, your life 🤡)

At 6 PM, someone knocked on Hannah's door.

It was Jung, wearing a cheap, secondhand middle-school uniform with a fresh bob haircut.

(Imagine opening your door expecting a quiet tutoring session... and letting in your own murderer instead.)

Jung confirmed Hannah was home alone, pulled out a knife, and stabbed her 

Once, 

Twice, 

Again, 

And again, 

Over twenty times!

Now, most killers panic after doing the unthinkable.

Jung? She went on a shopping spree (this is some crazy shi)

We are not joking. CCTV showed her calmly strolling(almost skipping) between Hannah's place, local convenience stores, and her own home.

Her shopping haul included:

Then she walked into Hannah’s bedroom, raided her closet, put on one of Hannah’s jackets, and wore it for the rest of the night.

(EXCUSE ME? The audacity level is off the charts.)

At 3 AM, she packed Hannah’s remains (SHE HAD DISMEMBERED HER BODY) into the heavy suitcase and hailed a taxi.

The driver saw her struggling and offered to help.

"No thanks. I've got it." 

She didn’t even let him touch it.

He drove her to a remote riverbank surrounded by dense grass. Forensic teams later noted the high moisture and bugs there would destroy evidence in days.

(Yeah... she definitely did her homework on that location.)

Fifteen minutes later, she walked back out, swinging that same suitcase effortlessly because it was now empty.

The taxi driver's spidey-senses immediately went off. And then came the ultimate twist: 

she got right back into... the exact same taxi.

The driver dropped her off, ignored the urge to mind his own business, and called the cops immediately. Five hours later, police picked her up (Korean police slayeddd literally)

Now, before we tell you what lies she told the police after she was arrested, did you know there’s a competition going on at Crime Lab headquarters?

Now back to the lies.

Queue the absolute worst legal defense in history:

Finally, her grandfather, who raised her, showed up at the station heartbroken and begged her: 

"Just admit what you did. Do it for me."

She finally confessed she had been plotting this for months, picking Hannah purely because she replied first (this is why I am not gonna reply anyone now)

Police checked Jung's phone: zero contacts, zero friends, no calls, no social media. For five straight years, she had lived entirely isolated in her room, lying that she was studying for civil service exams.

Classmates recalled her as a ghost-like figure who used to hide behind classroom curtains eating snacks and completely ignoring everyone.

(Imagine being completely invisible your whole life, only for the entire world to learn your name for the worst possible reason. INSANE!)

Psychologists evaluated her and found her psychopathy score was higher than some of the country's most notorious serial killers. And the scariest detail? Hannah wasn't her only target.

If Hannah had said no, someone else would have opened their door that night. 

As for the driver? He was offered a heroism award, but he turned it down, quit driving, and moved away out of fear she'd eventually come looking for revenge.

Honestly? We don't blame him one bit.

So, Detective... What makes you rethink your life choices?

Hit reply and let us know. We need a serious breather after this one.
