It is so important to find tools for a crime. In criminal cases, the tool of committing crime is an important part of the chain of evidence. At the same time, the more this type of crime tool involves professionals, the easier it is to locate the suspects.
For example, if it is a concrete wall broken with explosives, then the police in the technical department can analyze which kind of explosive it is based on the composition of the remaining explosives. If it is a regular explosive, they can consider mines and blasting companies. If it is a private synthesis, they can investigate the sales of chemicals in chemical stores based on the ingredients and find out the criminals who have illegally made explosives. Explosives can make a violent noise, which is, of course, inappropriate for use here.
The cunning criminals here had used high-tech tools that even the police could not figure out.
Captain Ma from the sub-bureau hurriedly came to report, saying that Monster Heavy Industries had the most advanced experimental analysis equipment in Jiangnan Province, which could help analyze the crime tools at the scene, so director Zuo and the other leaders almost pressed their cigarette butts on their hands.
"The most advanced in Jiangnan Province?"
If they could be number one in Jiangnan Province, then the country could also be ranked third in the top five.
"Hurry up, Xiao Zhang, take the things you collected on the spot and bring the safe there." Director Zuo stood up and couldn't wait to arrange the task: "There is also concrete, and the broken concrete will also be brought over. If they need it, they can also be invited to the crime scene for inspection."
After giving the instructions, Director Zuo suddenly thought of something and turned around and asked in confusion: "Captain Ma did the Monster Heavy Industry take the initiative to contact you? I remember your Chengbei branch was in charge of that piece."
"One hour ago, Monster Heavy Industries reported their company was also stolen, and goods worth 800,000 Yuan were missing."
"Damn~ what did you say?"
The leader of the room, his heart had beat violently in an instant. It was really a leak in that night, Daimeng Jewelry Company hasn't figured out what happened yet, and something went wrong in Monster Heavy Industries.
"Check, do everything possible to check, catch this group of people, I will let them deeply understand what is the iron fist from the Shanghai city police." Chief Zuo's angry cheeks slammed and puffed up.
Fifteen minutes later, two sirens of the Iveco police car galloped towards the masterpiece in front of the blue sky building. Zhang Zhitong sat in the car, looking at the huge and heavy safe beside him, his thoughts were a little messy.
The two round holes in the safe had traces of high-temperature ablation around them. The trace material evidence laboratory did not find out the specific combustion components, but it was certainly not traditional oxygen cutting ablation. The police were familiar with the marks left by oxygen cutting, and many two-pole robbers liked to use it to cut iron doors.
Oxygen cutting couldn't cut the safe at all, and it was even impossible to burn a total of ten coin holes in five safes in a short time. You should know there were only three robbers at the scene. Remove the time to demolish the wall and leave them time to break through the five safes, which will last half an hour.
The entire technical department thought about it all day but didn't think of the principle. Now, Mr. Ye of Monster Heavy Industry has offered to help them detect. This Mr. Ye was the middle school classmate of Zhang Zhitong.
Zhang Zhitong has never seen him since she went to the Silver Palace to arrest someone and broke into the box of this old classmate by mistake. Her old classmate had thoroughly mixed up, let alone the best in the whole school. In the sixty years since the establishment of Shanghai University, Ye Qing was also one of the best in the mix.
Not seeing the old classmate did not mean that Zhang Zhitong did not understand the situation of the old classmate. On TV, in the news, on the Internet, in newspapers, talks, Zhang Zhitong has heard and seen too many deeds about Monster Heavy Industry.
"Chief Zhang, I heard that you and the president of Monster Heavy Industries are junior high school classmates?" A female police officer sitting in the trace inspection room opposite her smiled: "If this President Ye is really capable of detecting important clues, Then we will be undeveloped in the technical department? If you encounter any problems, you will directly find your old classmate."
"Little Liu, labs cost enough money. Usually, those well-known laboratories require hundreds of thousands of Yuan to do a test. We are always in need. How much money do you think we can possess, hundreds of thousands of dollars? "
"Of course you can do it many times, chief Zhang, you are the most recognized police flower of our Shanghai Police Team. Which man doesn't think about you?"
"Well~ don't praise me, there are more flowers in the flower garden of the police flower school these days than criminals." Zhang Zhitong shook his hair coolly: "A man with ability, who wants to marry a policewoman, especially a criminal policeman. Three hundred and sixty-five days a year, there are three hundred days without touching the house."
"Know that Jiang Xuan of the squadron, last Tuesday, his wife had blocked the squadron leader in the street and had cursed it."
"Zhang chief, please tell me, I have heard many people tell me about this. But when I protested, they all pretended I was mysterious, saying I'm not married and I can't know about this." The two female policemen in the trace inspection car, the eyes were shining, and the fire of gossip was burning.
"Jiang Xuan's wife is about to get divorced. It is estimated that she is very angry. When shopping, she met the squadron leader and pointed to his nose and cursed. She said this lady in front of him had made love with her husband in bed three times this month. You are the squadron leader. I am married to a phone."
The young policewoman laughed out of breath, but the topic was not funny when she thought into it. She pulled the topic back to the president of Monster Heavy Industries: "It is spreading on the Internet that this President Ye has already ordered the world's most expensive and fastest private business jet."
During the small talk, the two police cars unknowingly stopped outside the Monster Industrial Building. After getting out of the car, two technicians received Zhang Zhitong and her party.
"You…what about Mr. Ye?" Zhang Zhitong always felt a little embarrassed, after all, the two hadn't seen each other for a while.
"Police officer, please, our president is in the laboratory."
Zhang Zhitong led the group of policemen and followed the two technicians to the inside of the civil air defense project. She was surprised all the way, waited before a thick blast door, replaced the white lab coat under the reminder of the technician, and walked into this pure white laboratory. The surprise of Zhang Zhitong and her colleagues rose to the top. What kind of laboratory is this, obviously it was a treasure house full of a gold mountain.
As far as the equipment they had in the bureau, Ye Qing had them all here, and they were all top models. For example, they have electron microscopes in their bureau, and here there were a high-level ten times the electric scanning and atom probes. They have a metal composition analyzer and here was an X-ray fluorescence spectrometer. They have trace element detectors and here were atomic absorption spectrometers.
If the laboratory equipment here was compared to a supercar, the equipment in their bureau would be the kind of remote-controlled battery car that children ride. However, there were taller devices that they couldn't name.
"Officer Zhang, we meet again." The only one here who didn't wear a white coat was Ye Qing. He stood in the middle of the laboratory with a smile, his eyebrows kept jumping.
"It's been a long time, Ye Qing." Zhang Zhitong also picked up the crooked eyebrows and swallowed his mouth at the technical houses in the laboratory.
The extra words were unsuitable for speaking now, Ye Qing beckoned and signaled the police to bring the object to be tested.
A large box of messy concrete blocks, a heavy safe, and some scattered debris.
Ye Qing knew that the police wanted to figure out what equipment the criminals used to break through the concrete walls and safes. In fact, Ye Qing himself was very curious.
Under the eyes of these policemen, the scientific researchers in the laboratory carefully placed the concrete fragments in a large sealed instrument. The appearance of this instrument was very sci-fi. On the pure white hatch, there was only an inconspicuous light green observation window, which made people confused about its purpose.
Zhang Zhitong asked the questions that all the police wanted to ask: "what is this instrument used for?"
"A holographic scan reconstructs this concrete wall with a digital model."
As soon as Ye Qing's voice fell, in the sci-fi cockpit, many green lasers had lit up and flickered.
