Gao Xiaoguang said doubtfully: "There is no trash can in the warehouse, so I threw the tea leaves into the black plastic bag."
"But...how can you find me based on these tea leaves? Tea drinkers There are too many, so there is DNA information on it. Even if there is, you can’t find me?”
Indeed, even if there is DNA information on the tea leaves, it is not comparable to Gao Xiaoguang, because Gao Xiaoguang is not suspected by the police? within the scope of people.
After all, Gao Xiaoguang left even bodily fluids in the victim’s body, but he still could not be found.
What Gao Xiaoguang didn't expect was that Lu Chuan could actually identify the type of tea residue.
Not everyone can afford Dahongpao, which costs more than 10,000 yuan a tael.
In addition, Gao Xiaoguang used selenium-rich spring water to make tea, which left a lot of clues for Lu Chuan's investigation.
The interrogation ended quickly, and Gao Xiaoguang was very cooperative.
At the same time, Lu Chuan finally got the final results of the DNA comparison.
When Li Donglin saw the final result, he let out a long breath.
success!
As expected, the comparison was successful.
This serial murder case that spanned 15 years and killed 11 people finally ended here
In fact, before getting the final DNA information comparison results, Li Donglin was still a little worried. of.
Although Gao Xiaoguang has fully confessed, it is difficult to say this case without ironclad evidence.
As long as there is no irrefutable proof of high blood pressure, you can go back to work at any time. It is useless now. The irrefutable proof is as high as the mountain. No matter how much Xiaoguang indulges, it is useless.
“Great job!”
Li Donglin waved his hand fiercely and said to Lu Chuan.
“Everything should be done.”
Lu Chuan also breathed a sigh of relief.
He had heard about this case in Dongzhou City when he was in school and studied the cases in it.
Although many details were not clear at the time, and naturally they were not as detailed as when he looked at the files when handling the case this time, he had actually heard of the general story of the case.
Precisely because I have known it before, and precisely because I heard about it when I was in school, I don’t have much confidence in Kuai Luchuan this time.
"Gao Xiaoguang has fully explained the entire murder process, as well as his planning process. All the details are basically consistent with what we have now."
Li Donglin was a little emotional.
They have been here in Tongzhou City for more than a week.
But we can’t go back yet. Although Zhu Panpan has been basically figured out by the coast, there are still ten cases before he can go back.
The cases that Gao Xiaoguang has done before must also be identified one by one and all the details must be explained clearly.
The serious crime team will be fully responsible this time, and Dongzhou City is just cooperating.
So Li Donglin still needs to lead the serious crime team to stay with the Dongzhou City Criminal Investigation Detachment for a while, and he will definitely be unable to leave in a short time.
That afternoon, Gao Xiaoguang was escorted to identify the scene.
The small warehouse at the scene of the first crime was finally opened.
It's actually very clean inside, and you can't tell that anyone has been killed.
Gao Xiaoguang was very cautious and he cleaned up the scene of the first crime very carefully.
It’s not just about cleaning up the blood stains at the crime scene. He used some chemicals to synthesize the iron ions in the blood stains, so under normal circumstances, it can’t be seen using infrared purple light. to the presence of bloodstains.
But Lu Chuan still found some blood stain residue in some cracks in the corners. This also confirmed from the evidence level that this small warehouse was the scene of the first crime where Zhu Panpan was killed.
This case has basically come to an end. Wang Song and Song Mingguang still need to provide further training to Gao Xiaoguang.
The murder circumstances of the first 10 victims require Gao Xiaoguang to explain one by one.
Li Donglin’s office.
Lu Chuan is reporting on work.
This is already the 10th day that the crime team has stayed in Dongzhou City, and the case has been solved quite smoothly.
Gao Xiaoguang remembers every detail of the previous 10 cases very clearly.
In addition, before every crime committed by Gao Xiaoguang, except for the first time, he had a very detailed crime plan. In the safe at home, the police found a small black book.
Gao Xiaoguang has a habit of recording all security plans in this small book. Before every killing, he will check the plan with this small book to see if there are any flaws.
Of course these plans don't always succeed.
Gao Xiaoguang’s black plastic book recorded a total of 14 murder plans, but he only carried out 10 of them.
There were 4 murder plans among which Gao Xiaoguang was forced to terminate the killings due to problems with the execution of the plans.
According to Gao Xiaoguang, from the first time he killed someone, he planned to kill one person every year, no more, no less.
Except for the first murder, he has made 14 murder plans, which corresponds to one killing every year. Normally he would have killed 15 people by now.
But because the plans of the four people had changed, Gao Xiaoguang was afraid that he would be exposed, so he did not take risks.
"Director Li, the work of the serious crime team has basically come to an end. It may not make much sense to stay here for the current investigation. I want to go back soon."
< br>Just after the Spring Festival, Lu Chuan came out, this time for another 10 days.
I haven’t seen my child for a long time and I miss my youth. I have long wanted to go back, but I am embarrassed. The members of the crime team were all around him and it was not good to leave him alone. .
Now Gao Xiaoguang's case has basically come to an end, and as an investigating detective, he basically doesn't have much work anymore.
"Okay, no problem, you can go back first."
Lu Chuan made great contributions to this case again. Li Donglin has already reported to his superiors, and the relevant job application reports have been prepared.
In addition, Li Donglin has obtained the consent of the provincial department and made a simple summary of the relevant materials on the case of the red-dressed killer in Dongzhou City, and then made a report to the ministry.
At the same time, Li Donglin also submitted a request report about the serious crime team and relevant individuals.
“After a while, when we are done with our work, let’s have a celebration banquet together.”
"Yes!"
After saying goodbye to the people from the serious crime team, Lu Chuan greeted Director Wu Guodong again, and then returned directly to Haizhou City.
Homecoming is like an arrow.
Lu Chuan seemed to have never been so anxious to go home before, but this time he didn't know what happened. He especially wanted to see his son. This was also his son. It was the first time Lu Chuan had left home for such a long time after he was born.
When you get married and have a wife, you have a family, but only when you have children do you have care.
Shen Yan's maternity leave has not yet ended.
After returning home, Lu Chuan’s parents were there.
"Mom, where is my son?" (End of Chapter)
