The main gas valve was wide open—far more than it should have been. And inside the bedroom, the ventilation duct had been deliberately blocked with a towel, wedged tightly from the inside.
Morales looked at his partner, his expression dark.
— This wasn’t an accident.
The ambulance drove off with the parents still unconscious. Sofia was temporarily taken into the custody of the officers, sitting in the back seat of the patrol car, as the sky began to clear slightly.
At that hour, no one imagined that what happened inside that house was not only the product of negligence or carelessness… but the first thread of a much more complex story, one that would involve debts, threats and a chain of desperate decisions that had led to that silent night.
And although little Sofia couldn’t know it, the truth that was about to come to light would change her life forever.
During the early morning hours, while Sofia’s parents remained in the ICU suffering from carbon monoxide poisoning, forensic investigators inspected every corner of the house. What initially appeared to be a domestic accident began to take on the appearance of something very different.
The preliminary report revealed that the towel found blocking the ventilation was firmly wedged in from inside the bedroom, but the boiler—allegedly faulty—had been tampered with
. One of the technicians looked up, serious:
“This doesn’t break like this. Someone deliberately messed with these valves.”
When Morales interviewed Sofía in the children’s care room, the girl answered with the trembling sincerity of someone who still doesn’t understand the gravity of what happened.
” Yesterday, Dad was very nervous… he was talking loudly on the phone and said he ‘couldn’t pay anymore.’ I was on the stairs and I heard… I heard someone tell him he had until today.
” “Did you see that person?
” ” No…”
“Does your dad usually have visitors at night?
” ” For the past month, men have been coming. Mom says it’s ‘grown-up stuff.’”
The officer wrote down every word. What the girl described sounded dangerously similar to extortion by illegal loan sharks. It wasn’t uncommon: indebted families resorting to quick loans, with no contracts, no collateral, just threats.
Meanwhile, at the hospital, Sofia’s parents remained intubated and in critical condition. Doctors confirmed that the poisoning had been severe and prolonged, meaning the leak had occurred several hours before the report.
In the mid-afternoon, the investigation took a turn when they reviewed the security camera footage from the residential complex. At 11:46 p.m., a hooded man was captured on camera walking toward the family’s house. His face wasn’t visible, but his build and the slight limp on his right foot were.
What was most unsettling was his departure: barely five minutes later, the man hurriedly left the area. Too little time to tamper with a boiler and block a vent… but enough for someone who already knew exactly what to do.
That night, Morales returned to the house to check minor details.
Upon entering his parents’ bedroom, he noticed something he had previously overlooked: a small mark on the doorknob, as if someone had held it with a rough glove. There were no signs of forced entry, but there was evidence of outside interference.
“This was premeditated,” he murmured.
He returned to his vehicle, frustrated and worried about Sofia. T
