I saw my son convulsing in the bed, the monitors blaring, nurses rushing in and out, one doctor ordering oxygen, another checking his IV line. A nurse pushed me back while I screamed his name.
That night I understood how close we had come to losing him.
The next morning I went to file a report. The detective listened to the recording, took notes, but was clear: it wasn’t enough. They needed physical evidence. Something that proved they were actually tampering with Mateo’s food or drinks.
That was when I called the only doctor outside Daniel’s circle whom I still trusted: Dr. Samuel León, a toxicologist.
He reviewed medical files, lab work, relapse dates, symptoms, visits.
—This doesn’t look like a spontaneous illness —he told us—. It looks like poisoning in microdoses. Small amounts, sustained over time.
The phrase pierced my chest.
With police support, they placed hidden cameras in my kitchen and living room. Every food item that came in was logged. Every container was kept. Every visit was monitored.
We waited three days.
Three days of pretending.
Three days of smiling at my mother while inside I wanted to tear her face off.
On the fourth day she arrived with a thermos of chicken broth.
—I made it with little vegetables, just how the boy likes it —she told me, kissing my forehead as if she were still a mother.
I let her in.
Paola came behind her, carrying a bag with cookies and juice. She was smiling too.
I smiled too. I don’t think I have ever hated myself more than in that moment.
When my mother thought she was alone, she pulled a small bottle out of her purse. White. No label. She opened the thermos, poured in a little of the powder, and stirred it slowly with a plastic spoon.
The camera caught everything.
Not a suspicion.
Not an interpretation.
Everything.
The police came in the next morning with a warrant. Paola started crying as soon as she saw the officers. She said it was a misunderstanding, that she knew nothing, that my mother manipulated her. But my mother did not cry. She didn’t even get upset.
She only looked at me while they put the handcuffs on her.
