Through a window

I live on the outskirts of Warsaw. Last year, a dead family of four or five people (I don't remember exactly) was found in the house across the street (we share a courtyard). It was on the second floor of a pre-war brick building, and it housed the boiler room; it was mostly inhabited by lower-class people. There was a newspaper article about the incident—it was attributed to carbon monoxide.

But I think something was off. They carried the bodies out in opaque bags—though maybe that's how they always do it? I don't know, since it was the only time I've seen anything like that in person. I distinctly remember the officials' faces as being overly tense and confused, inappropriate for the situation (though, then again, I don't regularly witness such events).

But most importantly, a local semi-alcoholic was running around hysterically during all this. He often collects bottles at night and rummages through trash bins. As far as I understood it, he claimed to have seen some kind of creepy creature climb through the transom (!) in that window. He's usually quiet, but that time he was very loud and nervous. I didn't catch the moment they calmed him down—I left for work the second shift.

After that day, he started drinking much more heavily, his hair quickly turned gray, and he started limping on both legs. Sometimes I see him, drunk as usual. It would be interesting to ask him about that incident. I have a bad feeling about it...
