Chapter 38

Gu Chen's words surprised everyone in the second scene, but they didn't understand what Gu Chen was saying.

"Gu Chen, what is your basis?" Comrade Li, who had been standing at the door, could not help but ask with shame.

He is an old comrade who often gives Gu Chen negative opinions.

Gu Chen explained: "although Zhao Heng is type a blood, although it is consistent with the results detected by forensic Liu in the threat letter, he belongs to non secretory constitution, which can eliminate the possibility that he is the murderer."

"Non secretory constitution?" Lu Weiwei bit her lower lip: "is there anything special about this?"

"Of course." Gu Chen looked at the dead Zhao Heng in a flash: "to put it simply, a person with non secretory constitution will not secrete blood type substances in saliva, sweat, Jing fluid and other secretive liquids, that is, it is impossible to judge the blood type from his saliva, sweat and Jing fluid samples."

Hearing this, Comrade Li was surprised: "that is to say, for non secretory constitution, the substances forming blood group are not mixed in the body Ye. Therefore, such people can not determine the blood type except blood, right?"

"Quite right." Gu Chen thanks Comrade Li for saving himself a lot of explanation.

"The secretory type and non secretory type of an individual are determined by genetic genes. The non secretory constitution group accounts for about 20% of the Han nationality. From the appearance, it is difficult to distinguish the non secretory constitution group from the secretory constitution group."

Gu Chen said here, officer Wang also secretly smacked his tongue.

He understood why Gu Chen was so surprised just now. He just wanted to speak, but Lu Weiwei took the lead.

"Younger martial brother Gu Chen, according to what you said, the residual saliva on the threatening letter is the real killer's blood type sample. But the saliva sample we sent to Zhao Heng today can't be detected at all, right?"

"It's sister Dilu." Gu Chen nodded and said with a heavy face.

However, on the other side of the phone, forensic Liu also heard Gu Chen's explanation. The heart said that he regarded me as a transparent person? Anyway, I should explain these things!

However, Liu did not mind, he continued in the phone: "yes, Gu Chen's analysis is what I want to say. These two saliva samples are not a person at all. If Zhao Heng is an accomplice, then there will be another murderer. Zhao Heng must have been killed by the murderer."

It has to be said that Liu has rich experience in forensic medicine. He also quickly passed his own identification and had a clear understanding of the case.

Otherwise, it will not be the technical backbone of the major criminal investigation groups that want to curry favor with each other.

"Where are you now, forensic Liu?" Gu Chen asked quickly.

"Don't worry. It's almost downstairs."

A few minutes later, Liu, with his assistant, came to the scene of the crime.

After preliminary examination of the dead Zhao Heng with professional instruments, he nodded his head and said, "it is confirmed that he died of poisoning. Judging from the time of death, it should be within two hours."

"In two hours?"

Gu Chen and Wang police officer and Lu Weiwei, three people exclaimed together.

"What?" "Is there a problem? In two hours, indeed? "

Gu Chen waved his hand and explained, "we don't mean that. It's just that the three of us just left this office two hours ago."

"So?" Liu Fa Yi was stunned.

Gu Chen said with a gloomy face: "Zhao Heng died of poisoning within two hours, which only shows that he died of poisoning shortly after we left. The time will not be too long."

Forensic Liu stares and looks at officer Wang and Lu Weiwei.

Both of them nodded hard, indicating that Gu Chen's statement was true.

"How did the killer do it?" Doctor Liu held his chin: "he can make Zhao Heng take poison without knowing it. There is only one possibility. The killer may be an acquaintance who knows Zhao Heng very well."

Liu forensic voice just fell, Lu Weiwei and officer Wang, eyes unconsciously looked at the side of the front desk miss.

The front desk miss is also scared, quickly waved her hand clear way: "not me, really not me."

"I know it's not you." Gu Chen said at the moment: "you have no motive to kill, and you can't kidnap Zhu linian's son just because of your body and bones."

You know, although Zhu linian's son is only 18 years old and weighs close to 80 kg, the front desk lady, with her thin arms and legs, has no use at all.

After hearing this, the front desk lady was relieved, but she had not recovered. Gu Chen then said, "but you may be an accomplice."

"Help Accomplices? "

The front desk lady's foot is soft, almost fell down, the whole person is at a loss and quickly said: "police Police comrade, don't take such a joke, OK? I'm innocent, and I've only been on my third day of work, and I haven't even been here for a week. Before that, I didn't know Mr. Zhao at all. You police can go and verify it. "The front desk lady is also flustered

How did she know that she became an accomplice in murder when she was in a class? It's scary to think about it, isn't it?

"Don't worry, don't panic. I'll ask you, who has entered Zhao Heng's office after we left?" Gu Chen asked again.

The front desk lady held her cheek to think and murmured to herself, "it seems that it's just me."

But when he thought about it, he cried out: "well Isn't that still me? I'm really wronged, boo Hoo. "

"Gu Chen, can you be mistaken?" "This sister, how do you think it doesn't look like an accomplice," Wang said

As a result, Lu Weiwei was not happy: "Lao Wang, which eye do you think people don't look like accomplices? Can it be felt? It depends on the evidence. "

Then she again to Gu Chen Nunu chin: "right, Gu Shidi."

Gu Chen did not speak, but Wang police officer was embarrassed.

The heart says that I am at least you lead? Usually, knead my head in the office just like kneading dough. In front of outsiders, don't you give me any face?

"Ludwig, I'm just guessing, OK?"

"You can't guess. You have to tell the evidence."

Officer Wang:

At this time, Gu Chen interrupted their quarrel. He continued to ask the front desk, "did you send anything after the three of us left? Think about it. "

"It's like Just send me a stack of materials? " The front desk lady was surprised and said, "yes, this stack of information on the desk of Mr. Zhao was always asked to give it to Mr. Zhao for reference. She said it was very urgent."

All of a sudden, everyone was quiet and their eyes were on the same page The pile of information that was thrown on the desk.

"Is it Zeng Ke who killed him?" Gu Chen hesitated for a moment, and the clue map group in his mind immediately began to quickly join together: "Zhao Heng died, could he have been the biggest beneficiary of this company? What's more, when I went to the park last time, I also went to the scene. Is it a coincidence

"But However, Zeng always just sent a stack of materials. He did not enter the office in person. My colleagues can testify to this point. "

The front desk lady is not flustered now. She starts to do everything possible to help Gu Chen provide useful clues.

Officer Wang also said, "Gu Chen, you may have thought too much. Zhao Heng died of poisoning. How could he have done it?"

"Unless There is one possibility. " Gu Chen's clue map group in his mind also completed the final splicing at this moment.

He now knows how the murderer poisoned Zhao Heng.
