STATUS: UNSOLVED
CLASSIFICATION: INTERNAL RECORD
CLEARANCE LEVEL: RESTRICTED
During the spring of 2020, millions of people around the world were confined to their homes.
Cities fell silent. Streets emptied. Restaurants closed. Entire neighborhoods retreated behind locked doors and drawn curtains while an invisible threat spread across the globe. For many people, the isolation was almost as frightening as the pandemic itself.
Inside a mid-rise apartment building, one daily ritual helped residents feel connected to one another.
Every evening at exactly 7:00 p.m., doors and windows opened throughout the building. Residents stepped onto balconies and leaned out of windows to applaud healthcare workers battling the crisis on the front lines. Pots clanged. Children waved homemade signs. Neighbors who had never spoken before exchanged smiles from a distance.
For nurse Lena Brooks, the ritual became a rare source of comfort after exhausting shifts at the hospital.
There was one part of the tradition she looked forward to more than anything else.
Apartment 9B.
Every night, an elderly woman named Mrs. Alvarez would sing.
Her voice carried softly through the building, rising above the applause and echoing through the nearly empty streets below. Most residents had never met her personally, but everyone knew the song. Over time, it became part of the neighborhood’s identity, a small reminder that even during isolation, nobody was completely alone.
For weeks, the routine never changed.
Then Lena noticed something strange.
Mrs. Alvarez stopped appearing at her window.
At first, it didn’t seem alarming. The elderly woman could have been resting, feeling unwell, or simply choosing to stay away from the window. Yet despite her absence, the song continued.
Every night.
Exactly on time.
The same melody.
The same volume.
The same crackling sound near the end.
Lena tried to ignore the growing feeling in her stomach.
After all, the world was already filled with anxiety. People were exhausted, frightened, and constantly expecting bad news. She convinced herself she was overthinking something harmless.
But the unease refused to disappear.
Three weeks after Mrs. Alvarez was last seen, a storm rolled across the city. Rain tapped against the windows while residents once again emerged for the nightly applause. As the familiar song drifted from Apartment 9B, Lena pulled out her phone and recorded it.
Later that night, she compared the recording to a video she had taken during the first week of lockdown.
The result made her blood run cold.
The recordings were identical.
Not similar.
Identical.
Every pause.
Every breath.
Every note.
Even the faint crackle at the end occurred at precisely the same moment.
Lena replayed both recordings over and over, desperately hoping she had made a mistake.
She hadn’t.
Someone wasn’t singing from Apartment 9B.
Someone was playing a recording.
And if the recording was being used to convince residents that Mrs. Alvarez was still alive, then a far more troubling question remained.
Where was Mrs. Alvarez?
That night, Lena made a decision she would later describe in her notes as unavoidable.
She broke quarantine.
The apartment hallway was silent as she approached 9B. The building felt different after dark, stripped of its usual sounds and filled instead with an uncomfortable stillness. Every step toward the door seemed louder than it should have been.
When she reached the apartment, she discovered it wasn’t locked.
The door opened with almost no resistance.
Inside, everything appeared perfectly organized.
Too organized.
The furniture was immaculate. The counters were spotless. Personal belongings were noticeably absent. The apartment looked less like a home and more like a carefully prepared display.
Then she found the source of the nightly song.
A mobile phone connected to a speaker system.
The device had been programmed to play automatically every evening at exactly 7:00 p.m.
For a moment, Lena simply stared at it.
The realization was horrifying.
Someone had gone through considerable effort to create the illusion that Mrs. Alvarez was still living in the apartment.
Someone wanted the building to believe nothing had changed.
Then she heard footsteps.
Slow.
Measured.
Approaching from the hallway behind her.
Lena turned.
Standing in the doorway was the building manager.
He wore a pair of gloves despite being indoors.
In one hand was an envelope marked with Mrs. Alvarez’s apartment number.
The monthly rent payment.
For several seconds, neither of them spoke.
The manager’s expression remained calm, almost friendly, as though he had expected to find her there.
Then he smiled.
Not a nervous smile.
Not a surprised smile.
A knowing smile.
The kind that appears when a secret has finally been discovered.
According to notes recovered later, his next words were spoken softly.
“You should have stayed inside.”
That was the last confirmed interaction between Lena Brooks and the building manager.

INVESTIGATIVE ADDENDUM
The incident remained unknown to authorities for several months.
Lockdown restrictions, reduced building occupancy, and limited contact between residents delayed any meaningful investigation. Many tenants assumed Mrs. Alvarez had relocated to live with family during the pandemic.
No missing persons report was filed.
No welfare check was requested.
No official concerns were raised.
By the time investigators examined Apartment 9B, the unit had been completely emptied.
Records indicated that rent payments continued to be submitted on time for several months after Mrs. Alvarez’s disappearance.
Financial documents later suggested the payments originated from an account linked to the building manager.
Authorities were unable to determine why.
No remains were ever recovered.
No confirmed cause of death was established.
Most disturbing was the discovery that the automated recording continued playing for weeks after Mrs. Alvarez vanished, effectively convincing an entire building that she was still alive.
Investigators believe the nightly applause created the perfect cover.
The noise masked subtle sounds within the building, distracted residents from unusual activity, and reinforced the illusion that Apartment 9B remained occupied.
The building manager resigned shortly before authorities attempted to question him.
He disappeared before a formal interview could be conducted.
His whereabouts remain unknown.
The final item recovered during the investigation was the phone used to play the recording.
The device contained dozens of scheduled audio files.
Most were copies of Mrs. Alvarez’s song.
One file, however, had never been played.
The recording was only four seconds long.
Forensic analysts enhanced the audio repeatedly before identifying a faint voice.
Believed to be Mrs. Alvarez.
The voice spoke only three words.
“He’s still here.”
