The scene of the crime was the lounge on the second floor of a historic badminton hall. The door lock was intact and the windows were closed. Changan looked at the falling ginkgo leaves outside the window and knew that it was normal not to open the windows at this time of year.
The deceased was a teenager. According to the school staff, he was Xiaodong, the son of the principal Liu Guang. The forensic doctor concluded that the time of death was no more than 24 hours, that is, after 18:00 yesterday Friday. The school staff said that the badminton hall was not open on Fridays and he did not know why Xiaodong had the key to the badminton hall.
It is no exaggeration to say that Chang'an has seen quite a few corpses, but only Xiaodong's one made him feel a little confused. A satisfied and obsessed smile appeared on Xiaodong's face, as if he was going on a long-awaited date. Such a smile was finally fixed on the face of the deceased. No matter how you look at it, it is a bit weird.
