Take the old attack to solve the case

The case that Sun Liang is holding is a carjacking and homicide case two years ago. The criminals intercepted a car on a self-driving tour in Chunri, shot dead a family of four, and threw the bodies on the side of the road. In the grass, he drove the stolen car and left calmly.

Huaguo has very strict control over guns. Generally, gun-related cases will be classified as major and important cases, and they will often be solved within a time limit so as not to cause greater harm to the people.

However, this case has been unable to be solved, because the road where the incident occurred was rarely passed by people and cars. The victim's body was only found a week later when the family reported the crime and searched. At that time, the murderer had already driven the car all the way to M province. , and then abandoned the car and fled.

Province M is in the northern border of China, and it is very difficult to find a person on the vast grassland. Moreover, everyone thinks that he has crossed the border and fled to the neighboring country.

The reason why Sun Liang noticed this case was because in this case, both the murderer and the victim were employees of Gaofeng Elevator Factory, and Gaofeng Elevator Factory was the elevator used by Xinghai Apartment Building.

There is another point in this case that Sun Liang noticed. According to people from the Gaofeng Elevator Factory, the murderer Ping Shengwei and the victim Cai Shaotian were both mechanics, and they had a very good relationship on weekdays. After the divorce, Ping Shengwei often went to Cai Shaotian. Shaotian's family was having dinner. Just a few days before the incident, someone saw the two of them going out drinking together. There was no sign of antagonism at all. So when the murder case spread to Gaofeng Elevator Factory, everyone's first reaction was Unbelievable, the second reaction is still unbelievable.

Sun Liang's fingers were unconsciously stroking the case files. Two people who had a good relationship suddenly fought each other. It might be because of certain things that they turned against each other, or it might be because of some interests.

He looked at the top of the file. This case happened in May two years ago. At that time, Sun Liang had not yet graduated from the police academy. For major and important cases, the city bureau and the four sub-bureaus below assist together. Even the provincial department sent people down, but it was useless to find anyone.

I don't know if the case two years ago is related to the current case.

He thought for a while, put this file aside, and continued to read the following case, intending to show it to Zhang Zimu after he finished questioning Tila Khan.

……

The questioning of the Uighur woman Tila Khan is still ongoing.

"Cheng Shi did give me some gifts, but we were in a relationship at that time, and I didn't know he was married, and they were all worthless things, police officer, are you going to ask me to return those things to you?" Is he his wife?" Tila Khan was a little nervous when he said this, and said: "Officer, I didn't lie to him, he gave them all voluntarily...and they are all things to eat and drink, should I spit them out and give them back to you?" His wife?"

Zhang Zimu looked at the woman in front of him who had obvious characteristics of the European race. She had long brown hair, fair skin, high nose and deep eyes, light color with a little bit of green eyes, and she also wore extremely delicate makeup. It can be denied that Tira Khan is indeed beautiful, but the nervous and greedy look on her face ruined her beauty completely.

Cheng Shi spent at least [-] yuan on this woman, but unfortunately there is no evidence preserved. Old people in the countryside rarely deposit money in the bank. Although there is a bank card, the most in the bank card is only a few thousand yuan. The cash is probably given directly to the woman. If the woman does not admit it, it will be very troublesome for Tong Miaoqing to recover her marital assets.

But what Zhang Zimu cares about now is not how much money Cheng Shi gave Tila Khan, but the barrel of grease that Tila Khan gave Cheng Shi.

"Oh, you said that bucket of hand oil, I gave it to him, it is made of our own sheep oil, I also use this kind of hand oil." Tila Khan said and put his own Stretching out his hand in front of Zhang Zimu, he said, "We raise goats over there. The smell of goat oil is not strong. Adding something can cover up the smell, which is very good for the skin."

"What did you add?" Zhang Zimu asked.

"It's just some spices, those that can cover the smell." Tira Khan looked at Zhang Zimu with some doubts, not understanding what was wrong with the hand oil he gave.

Zhang Zimu couldn't see anything unusual from her face, so he could only say, "Can you show us the hand oil you use yourself?"

Although Tilahan was puzzled, he still agreed.

……

Cui Xiaoyu accompanied Tila Khan to get hand oil, and Sun Liang walked into the captain's office with the information on the carjacking and murder case with a gun.

"I have an impression of this case. At the beginning, Team Lu on Beihai Road was overwhelmed by the deadline to solve the case. Later, he finally found the car. The car had been poured with gasoline and burned down. There were no clues inside. Moreover, the local The herdsman said that he once sold a horse to a foreigner, so he suspected that the murderer, Ping Shengwei, had already crossed the border. For this case, Team Lu was criticized by the higher authorities.” Zhang Zimu said.

"Captain, do you think these two cases are related?" Sun Liang said.

Zhang Zimu looked at the information in his hand thoughtfully.

On the surface, the case two years ago seems to have nothing to do with the current death case, but the murderer was an employee of the Gaofeng Elevator Factory and a mechanic, so it is very easy to destroy an elevator.

Could it be that Ping Shengwei is back?But even if he came back, why did he destroy the elevator and kill a decorator who had nothing to do with him?

Two years ago...

Zhang Zimu remembered that Cheng Shi started working as a decorator two years ago. He pointed at the table and said, "Sun Liang, go and find out what Cheng Shi did two years ago, and what else did he do?" Project renovation."

"Yes, Captain!"

……

Two years ago, it happened to be the hottest period of housing construction in Binhai City. Both the construction team and the decoration team were short of people. Cheng Shi was fooled by a few fellow villagers into resigning from the factory under such circumstances. hired a decorator.

"At that time, I often took on more than a dozen projects at the same time, and Cheng Shi was a newcomer, so he could only go where there was a shortage of people. I can't remember what projects he did at that time, but I still keep all the projects at the time. Records." The contractor said as he dug out more than a dozen thick information bags from the cabinet, patted off the dust and handed them to Sun Liang, and said, "I remember that Cheng Shi came to our company after the Chinese New Year the year before last. Here are the engineering materials of the year before last, last year and this year, police officer, you can bring them back to me after reading them."

"Of course." Sun Liangliang nodded, and asked the contractor to call someone to help move these information bags to the car. There are really too many original documents, and the stack is higher than others. Thinking of going back from so many documents Sun Liang couldn't help but feel a little headache when he found the clues.

……

Sun Liang, Huang Xiaoshi, and Li Boyan, who was temporarily arrested, searched for four days, and finally finished reading the information. They all looked pale.

All the projects were listed in the form. Sun Liang discovered that the dormitory building of the Gaofeng Elevator Factory and the homes of several employees were contracted by this decoration team. Not only that, the decoration team was also responsible for the workshop wires and sewers of the Gaofeng Elevator Factory. The laying of pipes.

The main workshop of Gaofeng Elevator Factory is not in Binhai City, but some of the product assembly is completed in Binhai City, so the workshop is not big, and the warehouse next to it is only five or six hundred square meters.

When Sun Liang suspected that the two cases were related, although Zhang Zimu didn't take it seriously, it's not easy to dampen the enthusiasm of his team members. In addition, there has been no breakthrough in the case. If Sun Liang wants to investigate, he should investigate it. Knowing it really made Sun Liang find out some connections.

But this connection is really not big, how can we find a breakthrough in it?

"Could it be that Ping Shengwei and Cai Shaotian had some interest disputes, and Cheng Shi saw it, so Ping Shengwei came back to kill people?" Zhong Yiyan scratched his head and said.

"Even if there was any dispute between Ping Shengwei and Cai Shaotian two years ago, he had already killed Cai Shaotian, and the matter has been settled, so why do we need to come back and kill someone?" Cui Xiaoyu patted Zhong Yiyan on the head with a notebook , said: "The brain is a good thing, why do you always go out without it?"

Zhong Yiyan shrank his head aggrievedly. These female soldiers in the team were not easy to provoke. If they were provoked, they would not only be beaten by the female soldiers, but might also be beaten up by the male compatriots.

Dong Jiajie thought for a while and said, "Could it be that Cheng Shi took something from Ping Shengwei and was killed?"

"What?" Huang Xiaoshi asked.

"Drugs!" Gong Yihao from the Narcotics Division said next to him: "More than two years ago, a batch of smuggled drugs disappeared after entering Binhai City. City, and there is no sign of transporting them out of Binhai City."

It was March of the previous year. In a thorough investigation of smuggling cases, the city's anti-drug brigade seized a batch of smuggled drugs. Nearly [-] kilograms of drugs were the largest amount of drugs seized in Binhai City over the years. During the interrogation, the trafficker confessed that he had transported [-] kilograms of drugs.

I have always said less, and I haven't seen anyone who deliberately said more, but no matter how the police investigate, the [-] kilograms of drugs seem to have disappeared out of thin air.

If Ping Shengwei and Cai Shaotian took the drugs back then, then there would be a reason for Ping Shengwei to shoot and kill Cai Shaotian. It is not difficult to understand why Ping Shengwei returned to Binhai City to kill Cheng Shi in desperation.

But will the truth of the matter be like this?

"Take drug-detecting dogs to search the warehouse of Gaofeng Elevator Factory, near Cheng Shi's dormitory, and... Tilahan's home and mutton restaurant."

"Yes, Captain!"
