Chapter 5 The Death of the Female Tamer
The circus lion has worked with the female trainer countless times. Every time the female trainer puts her head in its mouth during the performance, it cooperates very well and never hurts the female trainer.And on this day, when the female animal trainer put her head into the lion's mouth, the lion made an expression that seemed to be smiling, and then crushed her head.

Before the show, the lion ate a lot of meat, so it couldn't be because of hunger.It is also impossible for this lion to be in estrus, because the circus will not let a beast in estrus perform on stage.

So why did the lion kill the female trainer?
[Answer] This is a case where a lion was cleverly used to kill people. The smiling expression of the lion is actually the expression that it wants to sneeze.The murderer secretly sprayed a highly irritating drug on the hair of the female animal trainer. When the female animal trainer put her head into the lion's mouth on the stage, the lion sneezed due to the stimulation of the drug.Because of the great strength of the lion, he opened and closed his mouth and accidentally crushed the head of the female animal trainer.
