Solving the case: Combining the police dog's olfactory genes at the beginning

According to what Zeng Tianming said, he came back from the city at four o'clock and arrived in Ningjiang County at six o'clock. Obviously Zeng Tianming lied. Zeng Tianming arrived here at 3:40. If Zeng Tianming was driving normally, then He could arrive at the county seat at four o'clock, so where did Zeng Tianming go in the remaining two hours?

"The boss lady, give me a copy of the surveillance video." Luo Fei took out the prepared mobile hard drive and handed it to the boss lady.

"Ok, no problem."

"Luo Fei, are you finished reading now? Have you noticed?" After hearing Luo Fei's voice, Wang Lei quickly got up and walked over.

Luo Fei glanced at Wang Lei and told him what he had just discovered.

"Oh, Luo Fei, why didn't you tell me about the clues you found?" Wang Lei complained a little after hearing what Luo Fei said.

Luo Fei took the hard drive that the landlady had copied and glanced at Wang Lei, "I see you are chatting so happily on WeChat and I can't bear to disturb you. Besides, didn't I tell you now? Okay, let's go back and see you later You see."

After Luo Fei finished speaking, he walked straight towards the car, where the driver was still waiting for Luo Fei and Wang Lei.

Wang Lei was stunned by what Luo Fei said. He didn't realize it until Luo Fei was far away, and then quickly followed him.

As soon as he got in the car, Luo Fei called Yang Su and told Yang Su that he and Wang Lei had made some discoveries.

The car drove directly to the criminal police team. It was already half past six.

"Luo Fei, didn't you agree to treat me to dinner? Damn you." Wang Lei got out of the car and cursed.

"Are you still in the mood to eat now?" Luo Fei asked back, then looked at the driver first and said, "Master, please print out the invoice for me. I have to take it for reimbursement."

After getting the invoice, Luo Fei ignored Wang Lei and walked straight into the building.

Returning to a group of offices, because Luo Fei had called before, Yang Su, Xia Zheng, and Zhong Jun had not gotten off work yet.

"Luo Fei, you just said on the phone that you found some clues. What are they?" As soon as Luo Fei walked into the office, Yang Su stood up from his seat and asked impatiently.

Luo Fei investigated the situation today, including that Zeng Tianming bought a million-dollar personal accident insurance for his children, and that Zeng Tianming arrived at Yunnu Street at 3:40, but Zeng Tianming said that he only set off from the city at 4 o'clock. He arrived at the county seat at six o'clock and reported all these situations to Yang Su.

"Team leader, there must be something wrong with Zeng Tianming." Wang Lei, who had been unable to interrupt, waited for Luo Fei to finish speaking and quickly expressed his thoughts.

Yang Su touched his chin and said suspiciously: "It seems that Zeng Tianming does have some problems."

Then Yang Su looked at Luo Fei and asked, "Luo Fei, how do you think we should investigate next?" After the murder of Wang Fu, Yang Su now fully recognized Luo Fei's abilities.

Luo Fei was not polite either. No one was more certain than him that Zeng Tianming was the murderer, so he had the right to speak in this matter.

After thinking for a while, Luo Fei said: "My idea is to first confirm whether the deceased Zeng Xiaoguang is Zeng Tianming's biological son. At noon, I took Zeng Tianming's beard to the technical room for DNA testing. If it's quick, it should be done tomorrow morning. come out."

"Also, we can investigate Zeng Tianming's friends. If Zeng Tianming really killed his biological son to defraud insurance, then I have absolutely reason to suspect that Zeng Tianming must be in urgent need of a large amount of money somewhere. , otherwise he would definitely not do such a thing."

"But there is one thing that needs attention. When we were investigating and questioning Zeng Tianming's friends, I thought it would be best to find someone to monitor Zeng Tianming. I am worried that Zeng Tianming would probably run away if he found out that the police were investigating him."

Yang Su thought for a while and nodded, "Okay, in this way, tomorrow morning Zhong Jun and I will monitor Zeng Tianming, and the three of you will investigate the friends around Zeng Tianming."

If Zeng Tianming is really the murderer, this guy can even kill his own son. He is simply crazy. For such a dangerous person, Yang Su feels that it is safer to monitor him personally.

Then Yang Su reminded some precautions and asked everyone to get off work.

Luo Fei was the last to leave the office.

Luo Fei was just about to go down the stairs when he saw that the light in the technical room was still on.

"Who is still working overtime at this moment!" Somewhat curious, Luo Fei walked towards the technical room.

Walking to the window, Luo Fei saw Yang Mei and Wu Xiaoyue in the technical room.

Luo Fei did not enter the technical room, but took one look and left. Except for work matters, Luo Fei was not very good at dealing with girls.

The next day, Luo Fei arrived at the entrance of the criminal police building at 7:30, and happened to meet Yang Mei and Wu Xiaoyue, who were also buying breakfast and returning.

"morning"

Luo Fei greeted.

"It's so early, just to do a DNA test on the beard you sent me. Sister Yang Mei and I stayed up in the office until three o'clock in the evening. We didn't even have time to go home and sleep. I'm so sleepy now." Wu Xiaoyue rolled her eyes at Luo Fei, her eyes full of resentment.

"It's really troublesome for you two." Luo Fei was stunned for a moment, and then said sincerely.

Yang Mei, who was next to her, quickly pulled Wu Xiaoyue, then looked at Luo Fei and said, "Don't listen to Xiaoyue's nonsense. This is our job and it has nothing to do with you. By the way, the DNA identification report has come out, and it has nothing to do with the DNA of the deceased. The matching degree reaches 99.9%. You can go to the technical room to get the appraisal report later."

After Yang Mei finished speaking, she pulled Wu Xiaoyue, who wanted to say something else, and left quickly.

Luo Fei frowned. The DNA match reached 99.9%, proving that Zeng Tianming and the deceased were biologically related.

This Zeng Tianming is really a beast! Even his own son can do it.

Luo Fei did not go back to the group office directly, but went to the technical room first to get the DNA identification report.

Yang Su was already in the office, and Luo Fei handed the appraisal report to Yang Su.

"Biological relationship?" Yang Su looked at the report with a serious look on his face.

"That's right"

Luo Fei nodded.

At eight o'clock, Luo Fei, Wang Lei, and Xia Zheng set off from the criminal police team.

The first person Luo Fei and the others looked for was Zeng Tianming’s high school classmate. According to what they learned, Zeng Tianming currently has four classmates working in Ningjiang County. One works in the Electricity Bureau, one works in a bank, and one works in taxation. I worked in the bureau, and another opened a clothing store.

Luo Fei and the others first went to find a classmate in the clothing store named Lu Yong.

"I didn't have a good relationship with Zeng Tianming in high school. Although we were both in the county after graduation, we didn't have much contact with each other. I'm not very clear about his situation. You should look for Jiang Sanpang. He and Zeng Tianming have the best relationship. He is basically a best friend. If you ask him, he will definitely know." Lu Yong suggested to Luo Fei.

Luo Fei frowned and asked, "Where does Fatty Jiang work? Is he in the county seat now?"

"Pang Jiang, he works at the Electric Power Bureau. I heard that Pang Jiang and Zeng Tianming get together every week." Lu Yong replied.

Luo Fei frowned, "Is Jiang Sanpang a nickname?" Luo Fei and the others learned that Zeng Tianming did have a classmate who worked at the Electric Power Bureau, but his name was Li Dawei, and there was no one named Jiang Sanpang.

"Yes, we are all used to calling him by his nickname. His original name was Li Dawei."
