Gu Chen's words made everyone present stunned, but everyone couldn't understand and had no idea what Gu Chen was talking about.
"Gu Chen, what is your basis?" Comrade Li, who had been standing at the door, finally couldn't help but asked shamelessly.
He is the old comrade who often gives Gu Chen negative opinions.
Gu Chen explained to everyone: "Although Zhao Heng has type A blood, and although it is consistent with the results detected by forensic doctor Liu in the threat letter, he has a non-secretory constitution, which can already rule out the possibility of him being the murderer."
"Non-secretory constitution?" Lu Weiwei bit her lower lip: "Is there anything special about this?"
"Of course." Gu Chen instantly looked at the dead Zhao Heng: "To put it simply, a person with a non-secretory constitution means that his saliva, sweat, semen and other secretory liquids will not secrete
Blood type substances, that is, it is impossible to determine his blood type from his saliva, sweat, semen and other samples."
Hearing this, Comrade Li was suddenly surprised and said: "In other words, for people with non-secretory constitution, the substances that form the blood type are not mixed in the body fluid. Therefore, except for blood, this kind of people cannot judge at all.
Is the blood type correct?”
"Very correct." Gu Chen thanked Comrade Lao Li, which saved him a lot of explanations.
"The secretory or non-secretory type of an individual is determined by genetic genes. People with non-secretory constitution account for about 20% of the Han people. From the appearance, it is difficult to distinguish between people with non-secretory constitution and secretion type.
People with different physical constitutions are distinguished.”
When Gu Chen said this, Officer Wang secretly smacked his tongue.
He understood why Gu Chen was so surprised just now. He was about to speak, but Lu Weiwei beat him to it again.
"Junior Brother Gu Chen, according to what you said, the saliva remaining on the threatening letter is the blood type sample of the real murderer, and the Zhao Heng saliva sample we sent today cannot be detected at all.
Right?"
"Yes, Senior Sister Lu." Gu Chen nodded and said with a heavy expression.
However, on the other side of the phone, Forensic Doctor Liu also heard Gu Chen’s explanation and thought to himself, why should he treat me as a transparent person? After all, I should be the one to explain these things!
But Forensic Doctor Liu didn't mind. He continued on the phone: "Yes, what Gu Chen analyzed is what I want to say. These two saliva samples are not the same person at all. If Zhao Heng is an accomplice, then the murderer
There is someone else, and Zhao Heng must have been silenced by the murderer."
It has to be said that forensic doctor Liu is very experienced, and he quickly gained a clear understanding of the case through his own identification.
Otherwise, they wouldn't be the technical backbones that major criminal investigation teams are scrambling to curry favor with.
"Forensic Doctor Liu, where are you now?" Gu Chen asked quickly.
"Don't worry, we're almost downstairs."
A few minutes later, forensic doctor Liu arrived at the crime scene with his forensic assistant.
Then using professional instruments, after preliminary examination of the deceased Zhao Heng, he nodded and said: "It is confirmed that he died of poisoning. Judging from the time of death, it should be within two hours."
"Within two hours?"
Gu Chen, Officer Wang and Lu Weiwei exclaimed together.
"What?" Forensic Doctor Liu was stunned: "Is there a problem? Is it really within two hours?"
Gu Chen waved his hands and explained: "That's not what we meant. It's just the three of us who just left this office two hours ago."
"So?" Forensic Doctor Liu was stunned.
Gu Chen said with a gloomy face: "Zhao Heng was poisoned and died within two hours. That can only mean that he started to be poisoned and died shortly after we left. It won't be too long."
Forensic Doctor Liu stared, then looked at Officer Wang and Lu Weiwei.
Both of them nodded fiercely, indicating that what Gu Chen said was true.
"Then how did the murderer do it?" Forensic Doctor Liu held his chin: "He was able to make Zhao Heng take the poison without anyone noticing. There is only one possibility. The murderer may be an acquaintance who knows Zhao Heng very well."
As soon as Forensic Doctor Liu finished speaking, Lu Weiwei and Officer Wang unconsciously looked at the front desk lady beside them.
The lady at the front desk was also startled, and quickly waved her hand to clarify: "It's not me, it's really not me."
"I know it's not you." Gu Chen answered at this moment: "You have no motive for killing, and with your body and bones, you can't kidnap Zhu Linian's son."
You know, although Zhu Linian's son is only 18 years old, he weighs nearly 80 kilograms. With the thin arms and legs of the receptionist, there is no chance for him.
When the receptionist heard this, she finally breathed a sigh of relief, but before she could calm down, Gu Chen continued: "But you might be an accomplice."
"Associate...accomplice?"
The lady at the front desk lost her footing and almost fell down. She was at a loss and said quickly: "Police...comrade police, please don't make such a joke, okay? I'm innocent, and I'm only on my third day at work, and I've been working for a week."
Not even that. I didn’t know Mr. Zhao at all before this. You policemen can go and verify these things.”
The lady at the front desk was also panicked...
How did she know that when she was in class, she became an accomplice to murder? It’s scary to think about it, isn’t it?
"Don't be impatient and panic. Let me ask you, who has entered Zhao Heng's office after we left?" Gu Chen asked again.
The lady at the front desk held her chin up and thought, then murmured to herself: "It seems like it's just me."
But when I thought about it carefully, I almost burst into tears: "Well... isn't this still about me? I was really unjust, wuwu."
"Gu Chen, could it be that you made a mistake?" Officer Wang quickly said, "This girl doesn't look like an accomplice."
In the end, Lu Weiwei was not happy: "Old Wang, which one of your eyes makes you feel that this person does not look like an accomplice? Can you rely on your feelings? You have to rely on evidence."
Then she nuzzled her chin at Gu Chen: "Right, Junior Brother Gu?"
Gu Chen said nothing, but Officer Wang looked embarrassed.
You think I am your leader after all, right? You just knead my head like dough in the office, but don’t you give me any face in front of outsiders?
"Lu Weiwei, this is just a guess, okay?"
"Guessing is not enough, you have to rely on evidence."
Officer Wang: "..."
At this time, Gu Chen interrupted the quarrel between the two and continued to ask the front desk: "Then did you give anything as a gift after the three of us left? Think about it carefully."
"It seems... I just sent a stack of information, right?" The lady at the front desk said in surprise: "Yes, this is the stack of information on Mr. Zhao's desk. Mr. Zeng asked me to give it to Mr. Zhao for review. He said it was urgent."
Everyone suddenly became quiet, all looking at the pile of information on the table.
"Could it be that the murderer is Zeng Ke?" Gu Chen hesitated for a moment, and the clues in his mind began to be quickly assembled: "After Zhao Heng died, Zeng Ke should be the biggest beneficiary of this company, right? And last time I went to the park,
Zeng Ke also went to the scene, is this all a coincidence?"
"But...but Mr. Zeng just sent a stack of information. He didn't enter the office in person. My colleagues can testify to this."
The front desk lady stopped panicking now and began to try her best to help Gu Chen provide useful clues.
Officer Wang also said: "Gu Chen, you may be overthinking. Zhao Heng died by taking poison. How could Zeng Ke do it?"
"Unless... there is a possibility." The clue diagram in Gu Chen's mind also completed the final splicing at this moment.
