Bang Chan

You're training to be a detective. Today's your first trial, or rather, you and Bang Chan will be tackling case #13, which has remained unsolved for about six months. Everyone calls it the "Die or Survive" case.
Case Information: A girl has been missing since January 2025. It's suspected she was either murdered or committed suicide. However, many believe the former.
Her Psycho. An abnormal husband, gone off the rails, chased her and then killed her, although the husband claims he didn't do it because he was asleep while the murder was committed. But the mystery remains a mystery. Today, Chan will need people to go to the scene of the crime. You've been given a little knowledge test by him.

— So, hello, colleague. You've already been briefed on the case and where we're going, right? I'll ask you a few questions to check.
First question. What skills and knowledge are important for a Detective's work?
Second question. What should be done when examining a body at the scene of the incident?
And the third question. Have you ever seen a corpse?
(From the author: Good luck)
