At exactly 2:17 a.m., the emergency line at 112 rang through the quiet control room.
The operator almost dismissed the call before answering—night shifts were often filled with bored teenagers playing pranks. But the moment she heard the voice on the other end, she froze.

It was soft. Unsteady. So faint it barely carried through the receiver.

— Ma’am… my mom and dad won’t wake up… and the house smells weird…

The operator’s hand tightened around the phone. This wasn’t a joke.

— Sweetheart, can you tell me your name?
— Sofia… I’m seven…
— Okay, Sofia. Where are your parents right now?
— In their bedroom… I tried shaking them… but they don’t move…

Every instinct told her something was wrong. Emergency protocol was launched immediately. A patrol unit was dispatched to the address, while the operator stayed on the line, speaking slowly and calmly, instructing the child to step outside and wait in the garden, far from the house.

When officers arrived at the small wooden chalet on the edge of town, the scene was unsettling. Sofia was sitting barefoot on the cold ground, clutching a worn stuffed animal against her chest. Her eyes were red, her face pale—but she wasn’t crying. That unnatural stillness made the officers exchange uneasy glances.

As they moved closer to the front door, the smell hit them instantly. Gas—sharp and unmistakable—mixed with a faint metallic scent that lingered in the air. Officer Morales radioed for the fire department without hesitation.

The girl mentioned quietly that a few days earlier, she had heard her mother complain about the boiler making strange noises. No technician had ever come. No one thought it was serious.
