Firstly, thanks for the translation, I don’t know why people are complaining but if you are reading my comment I hope it will cheer you up a bit ヾ(❀╹◡╹)ﾉ~
Secondly, as many people have pointed, I also think the guardian killed those people because they were guilty of something fishy. Later on he discovered where the protagonist was and took him in not as a father, he drew a line from the start.
Thirdly, I agree that the detective is annoying, but I understand his POV and I think his death is necessary but at the same time I pity him, he was just doing his duty.
