Serious Crime Unit 1

Chapter 681
"They can also spend money to hire a murderer to murder Ding Hui. Ye Yayi must have saved a lot of private money, enough to tempt the murderer, like Yang Si hiring Guan Renqing to kill Yang Min's family."

"Yes, now we will target Ye Yayi and Ding Hui first and look for clues around them, such as purchasing drones and tetraethyl lead. If these two most important pieces of evidence are found, it will be ironclad evidence."

"If they buy these two things, it should leave traces on their account. This must be an anti-noise drone, otherwise it will be discovered. Therefore, the price is at least tens of thousands, or even tens of thousands. Purification Tetraethyl lead is not easy to buy, and a large amount is required to accurately spray it on Ding Hui, so the price is not cheap..."

"What if they use cash to ask friends to help buy it?" Jiang Yiming is most worried about this.Ye Yayi and Ding Ming are both smart and should not easily use their own accounts to purchase.

"Then we can only conduct extensive investigations. It is only a matter of time before we find evidence."

"Otherwise, we apply for a search warrant to search Ding Ming's home and Ye Yayi's villa. We may find physical evidence." Xiao Ke suggested.

"This is also a good method, but I don't think Ye Yayi and Ding Ming will easily leave evidence at home and wait for us to find it. They are all highly educated, especially Ding Ming. He has studied abroad and his anti-investigation capabilities are definitely Very high...I'm going to apply for a search warrant from the Bureau, and you guys are waiting in my office."

After a while, Jiang Yiming got the search warrant signed by Fang Lihua, and everyone went to Ye Yayi's house to search. Ye Yayi took the search warrant handed to her by Jiang Yiming, took a look at it and said: Please search, I'm afraid I will disappoint you.

Six people carefully searched the first, second and third floors for four hours, but found nothing.When parting, Ye Yayi was secretly proud, with a hint of ridicule. Although it was hard to see, Jiang Yiming knew what she was thinking. He said silently: Ye Yayi, you won't be proud for long.

After lunch, everyone went to the Qulihui Shang Garden, which is where Ding Ming lives. After he returned from Argentina, he bought 12 buildings with Room 504.This community was developed in January last year. It is located on Crystal Road in Jiangnan District. It is far away from the busy city and is clean and fresh. There are still many houses that have not been sold.

After Ding Ming read the search warrant, he invited them into the room. It was a house with three bedrooms and one living room. The decoration was simple and bright, and there was not much furniture inside. Therefore, it was very convenient to search, and there was almost no need to move furniture and items. They It only took more than two hours to complete the search, but there was nothing they wanted, which Jiang Yiming expected.

Ding Ming was very sincere and not as proud as Ye Yayi. He cooperated and opened all the locks, even the safe, and started the computer for Lu Yingying to check.Lu Yingying checked his online shopping records, QQ chat records, email, and Internet traces, but still found nothing suspicious.

Of course, this does not rule out his suspicion. The water is deep and the flow is slow. Criminals with high IQ cannot be seen on the surface. Just like Gao Chengyong, the murderer of the Baiyin serial rape and murder case, even his wife Zhang Qingfeng still cannot imagine that he and his wife Zhang Qingfeng can't be judged on the surface. Her husband of 30 years was actually a "murderer".

"Captain Jiang, I suddenly remembered that we only watched the video of Ding Hui and Ye Yayi after 20 pm on the 8th. We didn't watch the video of when she checked into Huayu Hotel. We only know that they didn't bring anything particularly big when they came out. If we start from She checked when she checked in and may have discovered something," Zhou Ting said.

"I know what you want to say. You think the drone should be larger, so they may take the drone to room 1704 of the hotel. Just check their backpack when they first entered the door and you can know whether they have brought it or not. Man-machine?”

"Yes, even if they have the ability to disassemble the parts of the drone and put it into their backpack, you can see whether they brought the drone into Room 1704 by comparing it with the backpack they came out of. If so, If so, then they can’t deny it.”

"You're right. You know that speed is the most important thing for me when handling cases, because I have to abide by the principle of golden time to solve cases. Therefore, mistakes will inevitably be made. We will pull up the video and check it immediately." After that, Jiang Yiming started the laptop on the table. , call up the video copied from the hotel and check it out.

They watched the video of Ye Yayi entering Room 1704 for the first time until night, and found no problem. Ye Yayi was only carrying a shoulder bag the size of an A paper. The bag was not bulging and could not hold the parts of the drone. Not to mention a drone.

Ding Ming walked into Room 20 empty-handed at 13:30 on the 1704th, and then walked out with Ye Yayi at 18:11, possibly to eat.After eating, Ding Ming went back to the room first, followed by Ye Yayi. Until they walked out of the room on the 21st, they did not bring anything suspicious, and no courier delivered it to room 1704.

Zhou Ting's speculation was denied.

Seeing Zhou Ting's disappointed look, Jiang Yiming encouraged him and said, "Don't be discouraged. Let's assume that Ye Yayi and Ding Ming took off the drone from room 1704 and sprayed venom at the scene. Then, the only entrance is the door of 1704. If they Why don't you pay the waiter to get room 1704 before you check in?" "Yes, why didn't I think of that?"

"We are not gods, how can we cover everything?"

"But...will the waiter take risks for money?"

"That's not a risk, it's just a violation. If you violate the rules and deliver luggage to a tenant, you'll get criticized by the boss or be fired. If Ye Yayi gave the waiter thousands or even thousands of dollars, they would definitely snatch it away."

"If your hypothesis is true, then when will the waiter send the drone to room 1704?"

"It should be after the guests who checked in on October 10th check out and before Ye Yayi checks in. This period of time is the safest, because the guests who checked in on the 20th did not send the drone in before checking out, and there is a risk of being discovered by the guests. , even if the guest is not in the room." Jiang Yiming looked at Zhou Ting, who was taking away the thermos cup to drink tea, and the tea cup blocked his chin.

"Then let's go to Huayu Hotel to check the surveillance video."

"Yes, we need to check who stayed in room 1704 the day before to see if this person is related to Ye Yayi or Ding Ming."

They came to the front desk of Huayu Hotel to check the check-in status of guests on October 10.After checking the registration record, the manager said: The couple who checked in from October 19 to 10 were from Sunjia Village, Harbin. The man's name was Sun Xiaobing, and the woman's name was Sun Lifang. They were both born in 15.They checked out at 19:1990 on October 10. They are frequent guests of Huayu Hotel.

Jiang Yiming checked the address books of Ye Yayi and Ding Hui. There were no names of Sun Xiaobing and Sun Lifang in it, which meant that they had no intersection. Then, he could only check the surveillance video again.

They copied all the videos from October 10 to 12 to a USB flash drive and took them back to watch slowly. First, they watched the video of Sun Xiaobing and his wife checking out and when Ye Yayi checked in. It took a total of two hours, except when the cleaner entered 21. Outside the room, no one went in.The cleaners were two middle-aged women. They went in together. Apart from bringing toiletries and sheets, they had nothing else to rule out suspicion.

Did Ye Yayi and Ding Ming use drones to enter Room 1704?If so, what tricks did they use?If this clue fails, we can only investigate whether they hired a murderer to kill. Murder by hiring a murderer is an extremely secretive and difficult case to investigate, and it is almost impossible to find the murderer in a short period of time.There is another clue that is tetraethyl lead, which Wu Jiang and Xiao Ke are investigating.

Wu Jiang and Xiao Ke investigated Ding Ming’s colleagues, classmates and friends. A man named Wei Jie said that Ding Ming had a close relationship with his classmates in Xiyan City. This man’s name was Zhu Jiawang, who was Ding Ming’s roommate at University. Zhu Jiawang's family was poor, so Ding Ming often helped him.Once Zhu Jiawang suffered from appendicitis and had no money to be hospitalized. It was Ding Ming who paid for his treatment. Zhu Jiawang regarded Ding Ming as a benefactor from then on.

Wu Jiang found Zhu Jiawang through the household registration system. He was the same age as Ding Ming and was also born in 1981.From the call records between Ding Ming and him, it was found that Zhu Jiawang did not talk to Ding Ming frequently and was not included in their visit.Maybe Ding Ming was afraid that the police would find Zhu Jiawang, so he deliberately called him less.

Zhu Jiawang might buy tetraethyl lead for Ding Ming. Even if he knew that Ding Ming might use it to do illegal things, Zhu Jiawang would buy it for him. After all, the relationship between benefactors is extraordinary.

However, if Zhu Jiawang does not admit to helping Ding Ming buy tetraethyl lead, they have nothing to do with Zhu Jiawang. It is impossible for them to apply for a search warrant and search Zhu Jiawang's home without reason, right?Even if a search warrant is obtained, evidence of his purchase may not be found.

Wei Jie said that Ding Ming often drove to Xiyan City some time ago, always going on Saturdays and coming back on Sundays.He said that Ding Ming drove a white Toyota sedan with the license plate number: Long A16589B.This brings convenience to the work of Wu Jiang and Xiao Ke.

Wei Jie is the deputy store manager and an undercover agent arranged by Ding Hui to monitor Ding Ming's every move. Ding Ming knows nothing about it. He also thinks that Ding Ming may be the murderer of Ding Hui. He has no idea about Ding Ming. Hui's murder was very sad, because Ding Hui was his nobleman, and it was Ding Hui who raised him from the position of salesman to deputy store manager. After Ding Hui's death, his future will definitely not be smooth sailing.
