yeah, the mad band member look suspicious for us viewer, he even around the crime scene. But my bet he is not the killer, just distraction to us.
The CEO also probably a distraction.
because of you, now i remember too that the injured one said that he have nowhere else to go. Dang, i don't pay attention who said that.
We'll see in upcoming episode, how is his arm. Tbh, from the scenes we got so far, it little chance that his arm is disfunctional.
the maid played by a well known face, she probably will have more screentime, or bigger role. But she is not the killer.
