"Criminal profile?"
Li Ze's words were a little sudden for Li Xiaojun.
But this was her profession after all.
Putting aside the question of accuracy, drawing a psychological portrait was not a problem for her.
Fu Xiaojun pondered for a moment and recalled the conversation between Li Ze and Lu Guangsheng in the forensics room.
"Male. Age unknown. Probably between 25 and 35 years old.”
"He has a high level of education, a strong learning ability, and a certain degree of anti-investigation awareness.”
"He had a deep grudge against the deceased's family.”
"Just now, the captain and Dr. Lu discussed the strangulation time and the wounds on the throat and trachea. Then the murderer should be weak and physically weak.”
"Recently, her personality has undergone major changes. She might have relatives around her who passed away under abnormal conditions.”
After he finished speaking, many people fell into deep thought.
If Fu Xiaojun's profile was accurate, then the scope of the murderer's investigation would be greatly reduced.
Wu Kang looked at Fu Xiaojun in surprise.
The other party had never mentioned the psychological profile of the murderer of the family murder case.
He did not expect her to have such a skill.
He had really underestimated her in the past, but he didn't know how accurate she was.
Even Li Ze looked at Fu Xiaojun in surprise.
As a top student of Jingzhou Public Security University, Fu Xiaojun lived up to her name.
The criminal profile that the other party had just mentioned was mostly the same as what he had thought.
Age was the big data of crime.
He had a high level of education, which was inferred from the murderer's modus operandi.
Without a higher education, most people would not think of using a syringe to inject the hormone, causing the victim to fall unconscious.
The reason why the murderer had a strong learning ability was that it was most likely the first time the murderer had committed a crime, and it was a revenge murder.
For this reason, he must have learned a lot of knowledge, including criminal psychology and counter-interrogation, in case he was really caught in the future.
The anti-investigation awareness was because there were no fingerprints left at the crime scene, and the surveillance cameras did not have any substantial clues.
Let's not talk about physical fitness or illness.
They had already discussed this in the forensics lab.
As for the murderer's change in mentality…
Fu Xiaojun's speculation was bold but reasonable.
If not for that, the murderer would not have chosen to kill his entire family.
The change in mentality was actually very simple.
It was either money, love, or hatred.
All three were possible, but the most likely one was hatred.
What kind of hatred?
Perhaps it was kinship, or perhaps it was love. The possibility of friendship was not high.
There was a saying that the saddest thing was to part in life and death.
Therefore, it was reasonable for Fu Xiaojun to infer that someone close to the murderer had passed away.
As for whether it was correct or not, there was no way to verify it now.
Everything was just speculation.
Or rather, it was a guess.
Whether it was true or false would depend on the results of the final investigation.
Criminal Profiling was a common investigation method used by criminal investigators. It could identify the general portrait of the suspect based on the criminal method and the analysis of the criminal psychology.
The accuracy rate was largely related to the criminal profilers 'abilities.
Low ability, low accuracy.
High ability, high accuracy.
Of course, criminal profilings were based on experience and existing clues. They could only be used as investigation directions and not as evidence.
It was extremely rare to find a highly skilled criminal profiler.
Therefore, the vast majority of investigators would not easily use criminal profiles.
This was because the margin of error was not high.
After all, there were many people in the world. It was very likely that there were people who were similar to the suspect or even overlapped.
Over-reliance on criminal profiles could lead to the arrest of the wrong person.
Therefore, it should be used as a reference.
However, Li Ze was different.
He had an astonishingly high accuracy rate in criminal profilings. He would use it frequently, greatly reducing the time needed to solve a case.
Seeing that Li Ze didn't immediately give his opinion, Fu Xiaojun was a little nervous.
"Captain, did I say something wrong?”
" No," Li Ze praised." It's very reasonable. It's already very good."”
Hearing this, Fu Xiaojun heaved a sigh of relief.
She was a little satisfied with Li Ze's approval.
After all, the other party was a well-known genius in solving cases.
When everyone saw that Li Ze had agreed to Fu Xiaojun's criminal profile, they started whispering.
They were impressed by Xiaojun.
It seemed like there was going to be a major breakthrough in the case.
On the other side, Wu Kang looked at Fu Xiaojun with some resentment after seeing Li Ze's affirmation.
He thought to himself,'You should have told me earlier that you had this skill.' He had been running around for half a month.
"But…"
At this moment, Li Ze changed his tone and said,""I have a different opinion on gender.”
"Judging from the modus operandi, I'm leaning towards a female.”
The meeting room fell silent.
"Female?"
Fu Xiaojun was surprised.
The others were also very surprised.
Within a day, he had killed four people.
His methods were all strangled to death. It was very cruel and clean, without any mercy at all.
The degree of ferocity was rarely seen in recent years.
Could such a vicious person be a woman?
Fu Xiaojun couldn't figure it out and quickly asked,""Captain, what makes you think so?"
