The fierce and loyal dog protects the fierce wife

Chapter 154 Sister Di found clues and forgot to eat and sleep to investigate the case (one more)
"We found your brother's fingerprints on the lighter, but another person's fingerprints, not in the database."

"That should be Chen Cheng's fingerprint." Meng Yidi pursed his lips.

Xiao Chiqiang was puzzled, "It stands to reason that since Chen Cheng gave you this lighter through your brother on purpose, he should have taken into account the issue of fingerprints. It's winter, so he can wear leather gloves when he sees your brother, but why would he Are you leaving your fingerprints on purpose?"

Several people present were deep in thought, leaving fingerprints, wouldn't that mean leaving clues for the police?
"Perhaps, he wants to tell me something." Meng Yidi couldn't help stretching out his index finger and gently pressing on his temple, trying to figure out what Chen Cheng or the person behind Chen Cheng was thinking.

After pondering for a moment, she thought of something, and immediately asked, "By the way, did you find anything about Chen Hui's residence?"

"Wait, I'll ask the city bureau to pass on the information." Xiao Chiqiang immediately called the city bureau.

Even if it was a holiday, the superiors personally called to inquire about the case, and the people from the Municipal Bureau did not dare to slack off, and quickly asked the colleagues on duty to package the case information and send it to Xiao Chiqiang.

Xiao Chiqiang immediately arranged a computer for Meng Yidi to analyze.

Meng Yidi had briefly communicated with Lou Shunyi, the head of the anti-drug detachment of the Municipal Bureau, so he knew something about this case.

She could read ten lines at a glance, and read all the archives within 5 minutes, and then clicked on the video where her colleague found Chen Cheng's back.

Sitting on someone else's desk, she was not polite, took a post-it note and a pen, and quickly recorded the video time.

"No, the time of Chen Cheng entering and leaving the apartment does not match the time of Chen Hui's death on the report. Is there elevator monitoring?" She couldn't help but turned her head and asked.

"Call Lou Shunyi directly and ask him." Xiao Chiqiang replied.

Meng Yidi didn't hesitate, and immediately called Lou Shunyi.

"Hi Team Lou, I'm Meng Yidi. I'm with Team Xiao right now and I'm looking at the case materials of Chen Hui's case. Now I have a question. Do you have the surveillance video of the elevator in Hui's building?"

"No, their building happened to be inspected and inspected by elevators in those two days, otherwise it must have been packaged together with other documents."

"Is that so? Then your colleagues who monitored Chen Hui later recalled the process of monitoring at the beginning, did you find anything wrong?"

"No, sorry, we..."

"It's okay, I'll contact you if there is a situation." Meng Yidi hung up the phone decisively.

She also knew that the City Bureau could not be blamed for this matter. If something happened, Chen Hui would not have been found dead at home. It could only be said that the murderer's modus operandi was too subtle.

"How is it?" Xiao Chiqiang asked.

Meng Yidi shook his head, and could only reopen the scene photos and evidence photos in the case files.

The photos helped to give her a clear and visual picture of the crime scene.

Suddenly, her eyes stopped on a picture of a trash can.

"This red one is a lighter, right?" Maybe she was stimulated by the silver lighter with the letter C engraved on it, so that she subconsciously stopped her eyes when she saw the lighter.

"It's a lighter." A male police officer behind her confirmed, "This kind of lighter costs [-] yuan each in convenience stores, and is the most common. It seems that this Chen Hui not only injects, but also burns."

Meng Yidi thought for a while, and immediately reopened the written materials of the case, looking directly at the column of evidence.

"What are you looking for?" Xiao Chiqiang dragged a stool and sat beside her.

Meng Yidi narrowed his eyes, and asked sideways: "Team Xiao, and this colleague, I have a question. For you boys, how long can a lighter last? It's just a one-off."

"This kind?" Xiao Chiqiang shook his head, "This kind is for occasional business trips where you have to fly and you can't bring a lighter. You only buy it when you get off the plane and get addicted to cigarettes. Basically, you only care about it for a few days, and then throw it away."

Another male colleague replied: "I use this kind. Although it has a long shelf life, it is really easy to lose it. I have it in the office, at home, and in my pocket. I can't remember it myself."

"That's it." Meng Yidi frowned, the answer was completely useless.

She pondered for a moment, then directly called Lou Shunyi.

"Captain Lou, your people have been with Chen Hui for a few days, but she basically didn't go out, did she?" she asked.

"Well, she has a chaotic schedule. After returning from the bar, she is basically at home. She should order takeaway for meals, and occasionally go downstairs to the convenience store to buy something."

"Can you ask your people to go and take her photo and ask her if she has ever bought a lighter in the convenience store downstairs. The boss should have an impression of a beautiful woman buying a lighter. Let's see if it is the latest one. matter."

"The lighter you're talking about is the one in her trash can?" Lou Shunyi asked.

"Yes, it's the red lighter. In addition, she may also shop online. Can you check her online shopping records? She may have bought tinfoil. I want both. Also, one-time Take a look at the syringe too."

"Okay, no problem, I'll have someone check it right away and get back to you."

"There is another question. I checked the evidence column, and the report said no fingerprints were found. Then I would like to ask separately, is there Chen Hui's fingerprints on the lighter?"

"Here, wait for me to ask the criminal investigator."

The two kept the phone open, and about a minute later, Lou Shunyi replied to Meng Yidi: "There are no fingerprints, and the body of the lighter is clean."

Meng Yidi frowned, "How could it be clean? It's something that was thrown into the trash can."

If the fingerprints are blurred and cannot be recognized, she still believes it. Could it be that Chen Hui or others are wearing gloves when throwing the lighter?

The colleagues behind Meng Yidi suddenly realized, "That's right, if Chen Hui used the lighter herself, then she didn't need to clean her fingerprints at all; if it was used by someone else, that would be possible! This lighter is clean, and it is Doubt!"

Meng Yidi nodded in agreement, and then replied to the other end of the phone: "Can you take a picture of that lighter? I want it from all sides."

"Okay, no problem." The two then hung up the phone.

Meng Yidi took a deep breath, and couldn't help stretching out his hand to press his temple again.

Fortunately, she slept soundly last night, and now she is sleepy, and her mood is slightly irritable.

Raising her hand to look at the time, she realized that it was already noon.

"Oh, yes, I forgot, go to the cafeteria and order two meals. It seems that it may not be a long time." Xiao Chiqiang ordered immediately.

A group of people analyzed and solved the case, and even forgot to eat.

One of the police officers immediately obeyed the order and went.

Xiao Chiqiang looked at Meng Yidi and said, "You asked Lou Shunyi to check the lighter and tinfoil, do you want to see if Chen Hui is still smoking?"
