I killed it, yes I did, I couldn't believe it and I know when i tell people they won't believe

I travelled to my uncle's place for a visit, on getting there I saw him in a fight with a man of which the man is a Son of an herbalist.
That night when we slept suddenly we heard a bird crying in the toilet of which window and door to the toilet is locked, what a surprise.
As a sharp guy, I quickly hit the bird with a plank till it was dead, I took the picture of the dead bird and I covered the dead bird with a tin. The following morning I called the neighbors to come see the mysterious bird but it isn't there, I checked the picture too and I couldn't find it either.
I COULDN'T BELIEVE IT and when I tell people they wouldn't believe it either
