Facing Lu Chuan's questioning, Gao Xiaoguang, who could not withstand the pressure, finally decided to surrender.
It’s really him!
Lu Chuan had an indescribable feeling in his heart.
Although until now, from Lu Chuan's perspective, the possibility of Gao Xiaoguang being a criminal suspect is already extremely high.
But he was still not sure that Gao Xiaoguang was the murderer.
The killer in red was on the loose for 15 years and committed eleven crimes during these 15 years.
Over the years, there have been experts from provincial departments and ministries.
Many clues were also found in the first 10 cases.
We have searched for criminal suspects on a large scale, and we have also conducted DNA information screening of suspects on a large scale.
But unfortunately, the real suspect has never been identified, allowing the other party to remain at large.
In the process of solving this case, it is not that the highly suspected criminal suspect has not been found, it is just that. In the end, it was either a coincidence or a smoke bomb released by the other party. In short, it did not point to the real murderer.
The Dahongpao tea residue in the garbage bag was originally just a small detail.
To be honest, if the tea residue was found in general, the criminal police could only regard it as ordinary residue when they saw it.
Nothing special.
In the past, Dahongpao was very expensive because it could only be produced from six mother trees.
Because the production is extremely limited, only a few hundred grams in good years.
So the price of tea is naturally extremely expensive, and most people can't even see it, let alone the river.
Later, asexual reproduction gradually began in these six trees on the northern and southern slopes of Wuyi Mountain.
It was only then that there were a few successful cases of Zishu, and the price of Dahongpao was slightly reduced.
Later, large-scale asexual reproduction made it possible for ordinary people to drink Dahongpao.
So now, in this era when Dahongpao is relatively popular, most people will dismiss this tea as ordinary Dahongpao.
If it weren’t for family reasons, Lu Chuan would definitely not be able to get in touch with him.
In addition, even if it comes into contact, if there is no trace evidence analysis of Dahongpao and the selenium-rich spring water above is not found, there will be no way to track and discover it.
In so many cases, over so many years, there are countless similar clues within the span.
What also makes Lu Chuan a little hesitant to believe is Gao Xiaoguang's identity.
Gao Xiaoguang is Gao Xinxin's younger brother. His Aijia Supermarket was developed with the support of Longteng Group, which can be said to be quite good.
And it has been 20 years since Gao Xinxin started his own business.
Gao Xiaoguang started committing crimes 15 years ago. At that time, his economic conditions were relatively good, or could be said to be extremely favorable.
How could such a person be such a psychopathic killer?
Of course, there are many things that I can’t figure out now, and it doesn’t matter if I don’t understand them. The answers will naturally be obtained through interrogation. After Lu Chuan received the information about the other party's surrender, he immediately called Li Donglin and reported it.
Li Donglin, who was listening to reports from other members of the task force in the conference room of the Tongzhou Criminal Investigation Detachment, looked surprised.
"Li Chu, what's wrong?"
Wang Song is reporting on the further screening of all personnel in the supermarket. Currently, he has received many clues.
The relationship between Zhu Panpan has also been further understood. Now he is working on expanding the scope of suspicion of relevant criminal suspects in order to conduct DNA information screening.
Seeing Li Donglin's face change suddenly after answering a phone call, Wang Song subconsciously felt that something had happened.
Song Mingguang and others also discovered something was wrong with Li Donglin.
"Li Chu, what happened?"
It took a while for Li Donglin to put down the phone and regain his composure.
He looked around at Wang Song and Song Mingguang, and at the other investigators from the Serious Crime Team who were strictly looking at the Dongzhou City Criminal Investigation Detachment.
Since the crime squad took over this case, everyone has not had a good night's sleep. Basically, they work until two or three in the morning every day, and there are even many people at three or four in the morning. Still working overtime continuously, with no time to rest at all.
Even his own eyes were red, and the dark circles under his eyes couldn't go away.
Even so, Li Donglin was under great pressure and did not dare to relax at all.
The last time the killer in red appeared was three years ago. At that time, Li Donglin was already the director of the Provincial Department of Criminal Investigation.
It was just that Li Donglin had just taken office at that time.
This case has always been handled under the supervision of ministries and commissions. After the killer in red appeared again, it can be said that the entire province was shocked.
At the same time, the ministries and commissions immediately made a judgment, and crime-solving experts came to help solve the case. Li Donglin also came to Dongzhou City in person.
Unfortunately, they stayed here for more than a month. Although they found many clues, they did not find the suspect in the end.
At that time, many of the directors of the Dongzhou City Public Security Bureau and the leaders of the Dongzhou City Criminal Investigation Detachment were dismissed from their posts.
There is no way, the case has not been solved, and the impact is so great, someone has to step out and shoulder the responsibility.
But this time, the crime team went off in person, and Li Donglin personally led the team. It can be said that the entire pressure was placed on Li Donglin's shoulders.
Although no one said who would take the blame if the case could not be solved this time, Li Donglin knew that it was the serious crime team that was in charge now. Yes, if the task force fails to solve the case, then he, the leader of the serious crime team, will naturally bear the responsibility.
Although the serious crime team has solved many cases since its establishment, it can be said that it has completed various important tasks assigned by the provincial department with a 100% detection rate.
That's what solving a crime is, it's either zero or one, there's no in between.
The suspect was either caught or not.
Now, nearly a week has passed since the serious crime team settled in the Dongzhou City Criminal Investigation Detachment.
Although there have been some breakthroughs in various aspects, many clues have been obtained and the scope of criminal suspects has also been further expanded.
But until Li Donglin received the call, they had not found any particularly clear clues.
Although the fingerprints discovered earlier have been successfully compared, it is already clear that they were smoke bombs released by the murderer.
The victim Zhu Panpan’s interpersonal relationships have basically been thoroughly explored, and basically all the people who have had contact with him have been traced.
Wang Song and Song Mingguang are centered on the supermarket where Zhu Panpan works, on South Lane 3 of Youhao Road where she disappeared, on North Lane 2 of Jianguo Road where the severed finger was found, and on the northern suburbs garbage dump where the body was found. From the geographical center, all personnel were screened for DNA information.
Although these screenings are still continuing, more than 1,500 people have been screened so far, but no comparison has been successful.
Is it possible... to screen all the people in Dongzhou City?
Sighed.
Li Donglin adjusted his expression and said slowly: "The murderer has been caught, the case...solved!" (End of Chapter)
