Regarding this case, Lu Chuan did some very deep thinking before holding the case analysis meeting.
Although the exact cause of death of the deceased has not been fully determined yet, and the results of the autopsy have not been released, based on Lu Chuan's experience, the possibility that the deceased died from a brain hemorrhage is very high.
Additionally, the current investigation results show that the deceased originally had a brain condition.
Thus, the most likely method the murderer used to kill may have been through some means of triggering this brain condition.
It could be drugs, or it could be some other kind of stimulation.
From Lu Chuan's analysis of the scene, it is highly likely to be the latter.
As for the locked-room murder, the on-site investigation can basically make a definitive judgment on this point.
"Everyone, look inside this lock."
All of the site investigation photos were taken by Lu Chuan himself.
Not a detail was missed.
