"This fully explains that the killer is highly likely male and has long been in a state of sexual repression."
"Additionally, we have extracted material from the deceased's lower body without finding any male components or condom latex residue."
"Therefore, I believe the killer is highly likely suffering from male dysfunction, unable to perform normal sexual activity."
"I suspect the deceased was a bachelor or a widowed elderly person."
Listening to Jiang An's analysis, Li Jian nodded lightly.
During the body examination, he stood beside us.
The injuries on the deceased left the deepest impression on Li Jian.
The inner wall of the deceased's vagina is indeed severely damaged.
Such severe injury, to some extent, reflects the assailant's psychological state.
From this characteristic, we deduce the killer's individual traits should be male, with high sexual demand, possibly with dysfunction, fitting the normal analytical process.
