On a cold morning in January 2016, commuters at a bus stop in Monterrey noticed an old leather suitcase abandoned near the bench. Most people ignored it, thinking someone had forgotten their luggage.
But by evening, the suitcase was still there. A young university student, Adriana LĂłpez, decided to alert the transit authorities. When they opened it, inside was not clothing, but a bundle wrapped in brown paper.
The bundle contained:
A torn staff ID card for Profesora Elena Vargas.
A childâs drawing of a woman holding hands with two kids.
A tape recorder with a cassette inside.
And a small notebook with only three pages filled.
On the notebookâs first page was a message written in shaky handwriting:
âIf youâre reading this, my name is Elena Vargas. I taught primary school in Colonia Independencia. I didnât run away. I was taken. And the people responsible work in places youâd never suspect.â
The second page had only one sentence:
âLook under Classroom 3âs floorboards.â
The third page was smeared with ink, but one word could still be read: âDirector.â

The police traced the ID â it matched a real teacher who had been declared missing in October 2014. Parents remembered her as dedicated and kind. She left behind two small children. Officials had claimed she might have left the city voluntarily.
But the cassette in the suitcase told a darker story.
When investigators played it, they heard a womanâs voice â trembling but clear.
âI donât have much time. They use the school at night. Trucks arrive when everyone is gone. If I disappear, donât believe the lies. Tell my children⌠I love them.â
Then silence.

Two days later, authorities quietly sealed off Classroom 3 at the school where Elena had worked. Workers reported seeing investigators carry out several crates in the dead of night. No explanation was given to parents or students.
The next morning, graffiti appeared on the school wall in red paint:
âThe director knows everything.â
---
Elenaâs children, now living with relatives, never received official answers. The suitcase vanished from evidence storage soon after.
And to this day, parents in that neighborhood still whisper:
What exactly was hidden beneath Classroom 3?
