Chapter 136 Coughing up blood
Xiao Zeng shook his head in embarrassment.

"I asked, and Zhang Guanglei's colleagues said that this is a private life, and they rarely inquire about it."

Xu Dayuan said in a deep voice, while Da Zhao kicked Xiao Zeng from the side, prompting in a low voice:
"This is a resignation, Xiao Zeng, do you have a girlfriend?"

Xiao Zeng shook his head.

"I don't have a girlfriend, and I'm exhausted every day. How can I have time to go on a blind date?"

Da Zhao nodded and raised his eyebrows.

"Look, it's just a matter of one sentence. We haven't known each other for a few months. If I ask you a question, you will say that they have worked for many years, and they will know this if they have a bad relationship. After all, people in a unit have personal relationships. , could it be that he, Zhang Guanglei, has never followed anyone?"

An older policeman in the team looked at Da Zhao and nodded. They knew him as Tao Zhenshan. He was an old man in the first team of criminal police. But when Xiaolongshan was involved in the case last time, he was absent on funeral leave.

"Zhao Henjian is right. It doesn't matter how good the relationship is. Either the deceased did not have regular friends of the opposite sex, or the relationship cannot be announced to the public, or even a relationship that is too embarrassing to talk about."

Xu Dayuan nodded and looked at Tao Zhenshan.

"Zhenshan, you're back too. Let's make another trip and go to the Water Conservancy Bureau to find out the situation. This Zhang Guanglei's hometown is not here, so he can't have no friends. Let's investigate carefully, especially his social relations and private life."

After Tao Zhenshan said yes, the door of the conference room was pushed open, and Xiao Liu led someone in.

"Captain Xu, we are back."

Xu Dayuan waved his hand, happily gesturing for them all to sit down.

"Exactly, tell me what you found when you went to the deceased's house?"

Xiao Liu's expression was not relaxed, and he motioned to a little policeman to put some photos on the big screen. Obviously this was the situation in the deceased's home.

"Through the household registration information, we found the deceased's home. After all, we did not find any identity information or keys in the deceased's car. We visited and confirmed that he lived here. At that time, several households downstairs were contacting the deceased. , Said that the upstairs has been leaking.

We hurriedly asked the unlocker to open the door. Once we entered the room, there was water everywhere. When we went in to check, we found that in the bathroom, the entrance pipe behind the toilet had been dismantled, and there were tooth marks left by a wrench on the metal hose. , we close the water valve.

The water in the room was ankle-deep, and it flowed out toward the corridor as the door opened. We took samples, and after careful inspection of the scene, we found no suicide note, certificates, valuables, or even three or five pieces of clothing of the deceased. Apparently he doesn't live here often. "

"It means that there is no harvest? Asked the neighbors?"

Xu Dayuan spoke unceremoniously. He didn't say that Xiao Liu was a woman at all, so he was more tactful. Xiao Liu couldn't hold back, but he quickly explained:
"I asked. The aunt on the first floor is the building manager of their building. She knows each house quite well. She said that Zhang Guanglei is a person who doesn't live at home. After all, he works in the Water Conservancy Bureau and always goes to reservoirs, dams, and flood control points for a month. Just stay at home for ten or eight days.

I asked my aunt, did Zhang Guanglei live alone at home, or did he bring people back to live with him occasionally?The aunt said, it seems to be a person, so I asked, did no woman follow?

Auntie said, but I didn’t see it clearly at night, and I saw Zhang Guanglei walking in, followed by a woman with big waves. Before I saw her face clearly, I knew that the woman with big waves was not very tall, and she was a head shorter than Zhang Guanglei. I saw it a few times, but I don't know if it counts.

Oh, by the way, the aunt said that Zhang Guanglei has been coughing for more than a year, and he has to rest twice when he goes home and upstairs. He can't go up to the fourth floor at once, and he is wheezing badly. His throat sounds like a bell The same, coughing and spitting out twice from time to time, and wrapping it in paper, she saw it once, it seemed to be coughing up blood. "

When Zhou Ning heard this, he propped his hands on the table and moved forward.

"When did it happen? I said coughing up blood, when did you find out?"

Xiao Liu quickly rummaged through the records, checked them, and quickly pushed the notebook in front of Zhou Ning.

"My aunt said that I saw him coughing during the Dragon Boat Festival last year. When guests came to the house on the August Festival and stood at the door of the unit to see off people, I saw Zhang Guanglei coughing up blood. His son told her to be careful. It wasn't some kind of infectious disease. .”

Zhou Ning frowned, the digestive tract was infiltrated like that, there were ulcers and bleeding spots everywhere, and he coughed up blood for more than a year, and no organic changes were found in the lungs. Could it be that his anatomy was not enough? carefulness?
Thinking of this, Zhou Ning shook his head slightly. The dissection was very careful, the lungs had been cut open, and samples were taken from all lobes. He got up directly, took out his phone and went to the corridor, and called Section Chief Cui.

"Sister Cui, I'm Zhou Ning."

"Well, say it!"

Cui Lili on the other side of the phone was even more straightforward, but Zhou Ning was very comfortable with such an opening statement.

"That's right. Among the organ samples of the deceased sent by Sun Gaotie just now, I need to do CA125, carcinoembryonic antigen CEA, and squamous cell carcinoma antigen SCC."

Cui Lili on the other side of the phone was obviously stunned, and then said a little puzzled:

"Do you suspect that the deceased had cancer, and that it had metastasized to multiple organs?"

Zhou Ning nodded.

"Well, the upper, middle and lower parts of the deceased's digestive tract can be seen, and there are ulcers and infiltrated bleeding spots, but I didn't find any substantial lesions, which is very confusing.

Generally, to achieve this state, at least the cancer is in the advanced stage, but there is no trace of disease in the internal organs, especially the lungs of the deceased, there is no discoloration and smoky oil deposition. I want to do a poison investigation for me. "

"Understood, first rule out cancer, and then check for poisons. It's okay if I check for poisons first, it's faster."

Zhou Ning was taken aback for a moment, but smiled in relief. In fact, the order does not matter. After all, the samples have been sent, and Cui Lili still has the final say.

"Sister Cui, you can do it as you see, in any order."

After hanging up the phone, there was no greeting such as goodbye, Zhou Ning quickly returned to the meeting room, at this time Xu Dayuan had already started to assign work.

"Okay, let's assign some work. I just said that Zhenshan is responsible for investigating Zhang Guanglei's private life. Don't worry about surveillance, it's someone who is close to the unit. Check it out carefully, especially his girlfriend. This is the most important thing.

In addition, when he returns home, check with Xiao Zeng's investigation results at the Water Conservancy Bureau. I don't think work is so busy. Didn't Xiao Liu find out the big aunt of the building? Ask around carefully, especially the guards and security. , Who is the person going in and out together, that 'big wave' I want to know her information tomorrow.

Xiao Zeng will go to the mobile company tomorrow, call up Zhang Guanglei's cell phone information, text messages and even multimedia messages, call me back one by one, compare the timeline, and the ex-wife Yu Meili, her current husband's car accident, is it true? Is it an accident?
Zhou Xiaozhou is going to contact Director Pang this time to see the autopsy results over there. If necessary, you can help me look at the corpse again. When your laboratory results come out, tell me as soon as possible, and go through it in the vehicle , to see if there are any residues of unknown fingerprints.

Of course, don't forget that Sun Manqing's son, how old is this kid? "

Big Zhao stepped forward, after all, he was the most comprehensive listener, and Zhou Ning didn't pay attention to these details.

"That kid is 16 years old, his name is Sun Yannian. He has the same name as an old pedant. It is said that he is not good at studying. In all subjects, except for the highest score of sports, the highest score is no more than 40. This time he joined his father and came here from Yancheng. He is in Qindao 102 again. In the first year of high school, it is said that Yu Meili found the person, the leader, you don't doubt this child, do you?"

Xu Dayuan glared, Da Zhao shrank his neck quickly, and hid behind Xiao Zeng, Xiao Zeng pinched Da Zhao, and Xu Dayuan snorted because of their small movements.

"Stop talking nonsense, I suspect everyone, but everything depends on the evidence. A big living person can't just leave nothing behind and run towards the lamppost. If he wants to commit suicide, there are many ways. Traffic accident, still want to cheat the insurance?"

After saying this, Xu Dayuan also paused.

"Forget about this, Zhenshan, please work hard, take someone to check Zhang Guanglei's car insurance policy, see who the beneficiary is, and whether his real estate is in his own name?"
