Take the old attack to solve the case

Zhang Zimu has always paid attention to training his subordinates. Many things will be handled by the team members below. However, there are too many things in a criminal police team. He has been looking for an opportunity to talk to Sun Liang today, but he finally found it until now. Take some time.

I can talk about Li Jinrui later, but now he just wants to know what happened to Sun Liang who was tilted 45 degrees but fixed in mid-air when he was in the Xinghai apartment building.Although he was very glad that Sun Liang didn't fall, the situation at that time was so weird that even Zhang Zimu and Chen Han were stunned for a moment before thinking of pulling Sun Liang back.

The more Zhang Zimu thought about it, the more frightened he became. Somehow, he suddenly remembered a book he had read many years ago. It said that a person made a deal with the devil. Although he gained some special abilities, he lost the most important things in his life.

Although he tried his best to tell himself that it was just a novel, but as long as he thought of the situation he saw this afternoon, he couldn't pretend that nothing happened.

"Captain, I..." Sun Liang really didn't know how to explain, he looked at Zhang Zimu with some distress. "Captain, I can't say it yet, give me some time, I...I have to ask before I know if I can say it."

Zhang Zimu looked at Sun Liang for a while, and wanted to ask him if this "ability" was given by Li Jinrui, but in the end he just nodded and didn't continue to ask.

At this moment, Pan Qingyue came over with a small white plastic bucket and said, "Captain, we found a bucket of grease."

Zhang Zimu took it over and took a look, only to see half a barrel of white oil inside, about two liters, but it is not sure whether this barrel of oil is the poisonous oil from the outside, "Take it back and check it, by the way Ask who knows the origin of this barrel of fat."

"Yes, Captain!"

……

Back at the police force, Sun Liang finished some things that needed to be recorded and sorted out. The clock on the wall showed that it was past eight o'clock.He stretched and stood up, just as he was about to pack up his things and go back, when he saw Zhang Zimu walking in hastily.

"Everyone go to the meeting room now."

Sun Liang and the others were all taken aback, and immediately stood up and walked towards the meeting room. There was only one possibility for a sudden meeting at this time. There was something wrong with Cheng Shi's death, and a case had to be filed.

……

"The deceased, Cheng Shi, was 28 years old. The time of death was around 04:30 on the afternoon of December [-]. The cause of death was a fall from a height.

After inspection, the deceased's hands were smeared with a kind of oil containing a variety of chemical toxins. After a long time, it would cause symptoms such as dizziness and disturbance of consciousness. The deceased had previously said that he was not feeling well, which should be caused by these toxins. of.

Because I didn’t get permission from the family members before, I just scanned the deceased. There were more than forty broken bones in the deceased’s body, and there were varying degrees of bleeding on the head and internal organs. There is no doubt about the cause of death, but look at this...the deceased Suffering from stomach cancer, which has spread to the liver and lymph nodes throughout the body, even if he did not fall to his death this time, he would not live for half a year. "Forensic doctor Zhan Xinyi pointed to a few photos on the monitor and said.

Former forensic doctor Zhan Xinru has already applied to be transferred to the trace inspection because he wanted a child, and the current forensic doctor is Zhan Xinyi.

"When we asked the deceased's co-workers before, they all said that the deceased did not show any special behavior before, nor did he say that he was uncomfortable in any way." Zhong Yiyan said.

Zhan Xinyi clicked on the monitor and said: "The deceased was suffering from gastric antrum cancer. The nerve distribution in this part of the tumor growth is not dense. Most of the time, there is almost no pain. At most, you will feel loss of appetite, or stomach is a bit blocked, and many people have stomach problems. People with sinus cancer don't know until it has spread."

"Isn't this already spreading?" Zhong Yiyan said.

"So I want to apply for an autopsy. I suspect that the deceased took some painkillers to cover up his illness." Zhan Xinyi said.

"Yes." Zhang Zimu nodded to Zhan Xinyi, and gestured to Pan Qingyue.

Pan Qingyue stood up, put a test report on the table, and said: "The test report of the barrel of oil found earlier has come out, it is the oil that the deceased smeared on the hands. This is the list of chemical toxins contained in it. There are seven kinds in total, all of which are common raw materials in chemical plants, a small amount of exposure will not cause much harm, but the content is too high."

After Pan Qingyue sat down, Zhang Zimu knocked on the table with his fingers, and said: "The results from the elevator inspection also came, they found a mechanism on the elevator door on the 21st floor, a small hidden button and a timer If someone takes the elevator between 04:30 p.m. and [-]:[-] p.m., this hidden button will allow the elevator door to open before the elevator arrives."

Almost everyone gasped. Although Zhang Zimu called everyone for a meeting before, they had already guessed that this case might be a murder case, but now it seems that this is probably an indiscriminate homicide case.

There are two elevators in the Xinghai apartment building. Between 04:30 pm and 21:[-], anyone who presses the elevator button on the [-]st floor will open the door without the elevator coming.Cheng Shi wanted to take the elevator at [-] o'clock yesterday afternoon, but fell down and died, and Sun Liang almost fell down at [-] o'clock this afternoon.

In other words, anyone can fall during that time period.

Dong Jiajie picked up the photo sent by the elevator maintenance and looked at it for a while. The mechanism is very simple. It is made of a few pieces of metal, large and small, plus a small LCD alarm clock, but it is this little thing with a very rough appearance. He killed Cheng Shi and almost killed Sun Liang.

After reading it, he sent the photo back and said, "Captain, I'm pretty sure that criminals know elevators very well. I suspect that his work should be related to elevators, such as design, manufacture, or maintenance."

Regardless of the fact that elevators are very popular nowadays, in cities, almost everyone takes elevators every day, but there are very few people who know about elevators. It's off.

Zhang Zimu didn't speak, but knocked on the table to signal him to continue.

Dong Jiajie thought for a while, and then said: "On the 21st floor of Xinghai Apartment, there is only one suite under renovation recently. The criminals may have targeted the deceased and several of his co-workers. As for the deceased...maybe he just didn't feel well..."

Even if the decoration workers do not work overtime at night, they will work until six o'clock. If the criminals really want to target the deceased and several of his co-workers, how can they set the time from 04:30 pm to [-]:[-]?It happened that the deceased was not feeling well after four o'clock.

So Dong Jiajie is a little bit speechless, there are too many coincidences in it, and coincidences often mean the calculation behind it.

"Telephone." Sun Liang said suddenly.

Everyone turned their heads to look at him, and Zhong Yiyan couldn't help asking: "What phone call?"

"The phone next to the deceased, could it be that someone called the deceased at four o'clock and asked the deceased to take the elevator?" Sun Liang said.

"But the deceased left because he said he was not feeling well." Zhong Yiyan said.

"That might just be an excuse for him." Sun Liang said.

"A person who suffers from cancer and uses poisonous oil doesn't need to make excuses at all." Zhong Yiyan was full of dissatisfaction.

Sun Liang thought for a while and said, "It wasn't the first day he got cancer, and it probably wasn't the first day he smeared poisonous oil on his hands. Why did he suddenly feel uncomfortable and asked for leave?"

Zhong Yiyan wanted to say something more, but Zhang Zimu knocked on the table and said, "Tomorrow I will go to Bureau Wu to file a case. It's too late today. I'll assign tomorrow's tasks."

"Dong Jiajie, Sun Liang, you two went to Xinghai apartment building to investigate, and the target is mainly on that institution."

"Yes, Captain!"

"Zhong Yiyan, Chen Han, go and investigate the origin of this barrel of grease."

"Yes, Captain!"

"Master Huang Xiaoyu, Cui Xiaoyu, go and investigate the deceased's social relations and interactions with others."

"Yes, Captain!"

"Okay, it's getting late today, everyone go back and have a rest."

……

When Sun Liang was packing up his things in his seat and planning to go back, Zhong Yiyan was still muttering beside him, always thinking that the deceased fell into the elevator shaft because he was sick and asked for leave to go home, and was dizzy.

Until everyone was gone, Sun Liang finally couldn't help interrupting Zhong Yiyan, and said, "Brother Zhong, what are you going to tell me? Now that there is no one else, you can hurry up and I'll be fine when I'm done." go home."

Zhong Yiyan froze for a moment, moved his mouth for a while, and then leaned over and whispered, "You just said...go home?"

Sun Liang's heart skipped a beat. When he said this, he didn't realize that he had already called Li Jinrui's home "home".

Zhong Yiyan saw that Sun Liang's face was flushed red, and the redness continued to spread, and in the end even his ears and neck turned red, he was speechless for a while, it seems that this guy is serious, he just wanted to say What, Sun Liang's cell phone rang suddenly, and he leaned over to take a look, only to see the words "Li Jinrui" written on the caller ID, and he couldn't help but secretly said in his heart, "You are really watching closely enough".

In fact, Li Jinrui really didn't stare at him closely, but Sun Liang almost had an accident today. Although he was rescued by Yingling, the two ghost slaves who had been stealthily guarding Sun Liang were still taken aback. It was too heavy, and they didn't dare to protect Sun Liang personally, which gave Ying Ling a chance to make a move. They hurriedly told Li Jinrui about it.

When Sun Liang left this morning, there was no sign of an accident on his face, so how could he be in danger again.

The more Li Jinrui thought about it, the more frightened he became, fearing that something would happen to Sun Liang on the way back, so he drove to pick him up.

Sun Liang hung up the phone, grinned at Zhong Yiyan, turned around and ran downstairs, thinking in his heart: "My wife is so virtuous, she actually came to pick me up from get off work."

He didn't know at all, Zhong Yiyan looked at his back with a heartbroken face, a good brother became someone else's wife, this husband took his wife from get off work or something... the relationship between superiors and subordinates is too obvious.
