Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 59 What is the murder weapon?

In a women-only steam room, an exclusive club hostess is killed.The deceased was naked and stabbed in the soft abdomen.Judging from the wound, the murder weapon might have been a short knife.But apart from an empty thermos bottle, there was no knife that looked like a murder weapon in the bathroom.

Because there was another waitress in the bathroom at the time of the incident, this person is believed to be the murderer.But the masseur who was outside the door clearly saw that this person came out of the bathroom empty-handed and naked.And until the body was found 15 minutes later, no one entered or exited the bathroom.

So, what weapon did the murderer use and where did he hide it?

[Answer] The murder weapon was a sharp short knife made of ice.In order not to melt the ice, the murderer put it into a thermos bottle, filled it with dry ice, and brought it into the bathroom.And taking advantage of the opponent's unpreparedness, he suddenly assassinated.When the body was found, due to the heat of the steam bath, the short knife made of ice and the dry ice naturally melted completely.If it is a soft abdomen, even with a short knife made of ice, assassination is not a problem.
