I knocked on Lao Zhang's office door and walked straight in.

"Zhou Cheng, you're here! What are the results of a check-up at the hospital? Lao Zhang, who was wearing a pair of glasses and was sorting out something, saw me and asked with great concern about the examination at the hospital today.

"The check is that Huang Na is pregnant." I sat down next to Lao Zhang.

He lifted his glasses up and put down the work at hand, "You kid is really blessed, he has only been married for two weeks and has become a father, so he is in morning sickness in the forensic office today?"

I nodded.

"That's not right!" Lao Zhang tilted his head as if he was thinking about something, "As far as I know, morning sickness is a reaction after a month, both of you are moving a little fast, it seems that ......"

Lao Zhang didn't finish his words, he looked at me with a meaningful smile, and the two of us understood in an instant.

I nodded embarrassedly, "It seems that people who become fathers are different, you know!" I teased him.

"Alright, alright! Seriously, what are you doing with me? "Can I understand that Lao Zhang deliberately changed the topic?

"Didn't you and Xiao Wang visit the families of the two male victims before? I'd like to look at your records, as well as the family circumstances of the two previous female victims, and I always feel that there is a disconnected connection between them. "I got down to business and explained my intention to Lao Zhang.

"Wait a minute," Lao Zhang hurriedly looked for the information I wanted from his stack of documents, and Lao Zhang handed me two folders. "I always felt like there was a connection between the two."

"Look, these two female victims also worked in the urban area before, and the two male victims also worked in the urban area before." Lao Zhang pointed to the information on the two documents and said to me, "Could it be that they are in the same place?"

"Find where the four of them used to work?"

"I asked my neighbors and their parents, and they all said that they only knew that the victim worked in a factory in the city, but they didn't know what he was doing. I don't know which factory it is? ”

"Then start the investigation one by one from the factories in our urban area." I think this can only be used as a dead horse doctor.

"It's the same as I thought, so I transferred the information from above, and I'm investigating them one by one."

"Did you check the results?"

Lao Zhang shook his head, "We have a total of one hundred and fifty-two factories in this place, and now only one has not been checked, and the final bet is on this, if there is no more, then all the clues we have caught will be broken." ”

"Then bring it quickly, let's take a look together."

Lao Zhang picked up a document from the table, which said'Employee Information of Ziyi Food Processing and Production Factory', I opened the document, pointed to it with my finger, excluded them one by one, and turned to the last page, when I was almost hopeless, I saw the names of Zhou Xing and Wang Zihan, and Lao Zhang saw the names of Li Xiao and Shangzhi.

"Lao Zhang, look, the names of Wang Zihan and Zhou Xing." I pointed to the two names on the document and said to Lao Zhang with a little excitement.

"I saw it, I saw it, you see the names of Li Xiao and Shangzhi here." Lao Zhang pointed to the position of the last few people on the right side of the Chinese file in my hand.

I looked at the place where Lao Zhang pointed and saw that there were indeed these two people.

"Lao Zhang, quick, check the information of the four people." I said to Lao Zhang, and Lao Zhang immediately took out the information of the four contacts from the desk.

After checking with Lao Zhangyi, I found the information of the four people on this document, and the information of the four victims, and found their home addresses, ages, and ...... They are all exactly the same, which is enough to show that they are the same person.

In this way, the four victims were finally connected by us.

"It's really hard work, and I finally connected the four victims." I was not shocked and sighed, "Let's go to this factory when we have time," I turned to Lao Zhang and said.

Lao Zhang nodded in agreement!

At this moment, there was a knock on the door.

"Please come in," Lao Zhang said.

The door opened, and it turned out to be a forensic doctor.

"Team Zhou, I just went to the office to look for you, only my sister-in-law was there, he said you were here in Lao Zhang, so I came over." The medical examiner came in, holding a folder in his hand, and said to me.

"Did you make any new discoveries?" I asked the forensic doctor.

The forensic doctor opened the folder, pointed to it and said, "Team Zhou, one thing is certain at present, the two male victims and the two female victims were killed by the same means of committing the crime, and the fatal cause was that the temple was severely injured, and the next thing is to see if there is any connection between the four of them." ”

"Okay, give me a copy of this document."

"Take it, I've got one left." The medical examiner handed me the documents and I got them from the medical examiner's hands.

"By the way, we have just found evidence that the four of them are indeed connected, and they all work in the same factory." Lao Zhang said to the forensic doctor.

"Then this is a good thing, I have found a breakthrough, I just thought that I could only prove that it was done by the same person, and it didn't help the progress of the case, but now it's okay, there is a place to start." The forensic doctor listened to what Lao Zhang said and felt full of hope.

"Forensic doctor, can you tell what tool hit the temple and killed the victim?" I asked the medical examiner.

"Yes, but there is a problem, the equipment of our police station is not very advanced, if I want to find it, I need a tool to try, it will take some time."

"How long will it take?" I asked.

"Two days, it should be enough." The medical examiner replied.

"Well, try your best! I think that by finding the tools to commit the crime, we can better eliminate the suspect. ”

"Actually, I think when the murderer hurt two male victims, he used something like a dart, and this kind of thing is not common in our lives, so I think if I look for it, I can still find it."

"That's good! I've had to work hard for you these two days! If you need any help, just ask me and Lao Zhang. "I said to the medical examiner.

"Uh-huh, non-existent, my duty. Are you going to go to that factory? ”

"It's definitely too late to go today, and others are going to get off work. Let's go on a run with me tomorrow, does Lao Zhang have any arrangements for tomorrow? ”

"Nothing important, I'll go with you tomorrow! Depart from the police station at 9 a.m. Lao Zhang replied to me.

"Okay, that's it."
