The recording was put to the back, and the voices of the two brothers became more and more trembling, and there was a sobbing sound in their voices. I can hear it: two men are full of reluctance to the world, their mother and sister. But it is also true that they sinned. If you kill someone, you will pay for your life, and you will be punished by the law. No matter how much you can't help yourself, unfortunate and sad. Law - never merciless.

After listening to this recording, Jiang Chonglang and Zhang Lanshan were silent for a long time. After a long time, Zhang Lanshan said: "The corpse needs to be further examined, and the recording must also be handed over to the traces department for examination to see if there are any suspicions." Let's not inform their eldest sister and old mother so early, okay? ”

Jiang Chonglang nodded and played the recording again. But when he heard it again, Jiang Chonglang heard that there seemed to be some other voices inside. And when he turned up the volume to the maximum and listened to it again, he found that it was the prompt sound of the QQ message, and he also heard the sound of some high heels hitting the ground, and there was a vague "hum" from a woman.

Obviously, the last words of the Sun brothers were not recorded in their own family. It stands to reason that it is impossible for others to watch such a last word by others, if this recording was recorded by the two brothers who were threatened, then their death, and even Wang Lulu's death, are there doubts. Without further ado, Jiang Chonglang sent someone to send the body back for autopsy first, while he stayed to inspect the scene. At the same time, someone was sent to call up the Sun brothers, and all the trip surveillance videos after returning to Yangcheng.

After a night of autopsy, Zhang Lanshan concluded that the time of death of the two Sun brothers was noon on the day they returned to Yangcheng, and the cause of death was indeed carbon monoxide poisoning. And in the stomachs of the two brothers, residual gastric digestive sleeping pills were found. The composition is the same brand as the sleeping pills found at the site of the crime.

On both bodies, no traces of fighting or coercion were found. And whether it is on the sleeping pills and water glasses, as well as the gas switch button and the mobile phone that recorded the last words, only the fingerprints of the two brothers appeared, and there were no other people's fingerprints. In other words: the gas was prescribed by the Sun brothers themselves, the sleeping pills were taken by the Sun brothers themselves, and the last words were recorded by themselves. Summary in one sentence - the two brothers of the Sun family did commit suicide.

But on Zhang Lanshan's body of Sun Baohe, there was a new discovery. Between Sun Baohe's nasal cavity and fingers, a little powder was found. Laboratory analysis revealed that the powders were pollen. Including magnolia flowers, but also azaleas, moon flowers, and so on. And through the monitoring of Yangcheng City, it was confirmed that the two brothers of the Sun family got off the bus and went straight to a building, and on the small square in front of the building, there were several magnolia trees, on which the magnolia flowers were blooming. What's more noteworthy is that Wang Lulu's former work unit is in this building. The monitoring shows that before the two brothers walked into the two buildings, Sun Baohe was still under the magnolia tree, stopping to admire and touch the magnolia flowers for a while.

Less than an hour later, the two brothers left the building. Immediately after that, I got on a bus and got off at a pharmacy. Shen Bin asked the owner of the pharmacy that the sleeping pills they had taken before committing suicide by turning on the gas were bought at this pharmacy, and this pharmacy was very close to their home. After leaving the pharmacy, they went into the alley and never came out again. By this time, it was almost noon, and the two brothers had died during this time. It can be proved that the two did commit suicide in fear of sin.

A bank card was also found at the scene of the crime, and its owner was Wang Lulu. According to the access records, there was originally 50,000 yuan in the bank card, which was taken by the two brothers of the Sun family and transferred to their own accounts in the previous few days. Why did the two brothers of the Sun family go to the place where Wang Lulu worked before their deaths before committing suicide. What are they going to do there. It stands to reason that they have a deep old grudge with Wang Lulu, could it be that the two brothers found out in their conscience that it is not very reliable to go to the place where Wang Lulu worked before her death to worship her.

"Hire a murderer" Jiang Chonglang's mind flashed this word, "That's right, someone must have paid to hire Sun Baojiang and Sun Baohe to kill Wang Lulu, and gave them both a good reward." It's just that I didn't expect the East Window incident to happen, and what promises did the buyer give to the two brothers. The two brothers decided to take all the blame on themselves. ”

In order to verify his idea, Jiang Chonglang called the provincial capital of Chunze City. Ask for help investigating a matter.

There was a quick response: less than two hours after the death of the two brothers of the Sun family, they had another 500,000 yuan in their accounts. And someone has already helped Sun Baoyue contact a nursing home, and after Wang Cuifen recovers, she will be able to live in it until she dies.

Jiang Chonglang checked Sun Baojiang's mobile phone again and found that the mobile phone card inside had been taken away. It seems that the murderer was afraid that the police would find him through the call logs.

"Looks like I'm right." Jiang Chonglang summoned all the members of the serious crime team to a meeting. "This rape, murder and destruction of the body is not an accident, but a long-planned murder for hire. The two brothers of the Sun family were hired to kill Wang Lulu at a high price. It's just that I didn't expect the incident to happen so soon, and the murderer used the illness of his grandmother Wang Cuifen and the life guarantee of the rest of his life as a threat to force the two brothers to confess. In the end, Sun Baojiang and Sun Baohe chose to commit suicide, and they wanted us to close the case. But we must dig out the real culprit behind the scenes.

If we want to catch the employer behind the scenes: we can start from the social relations of the deceased to see if the deceased has any enemies; You can also start from some of the physical evidence left behind: such as the incense powder on the bag containing the sulfuric acid water bottle, the source of the sulfuric acid water, and the source of Sun Baoyue's card money. Of course, if you can know who they went to see that day, then it will be easier to solve the case. ”

Jiang Chonglang came to the building where Wang Lulu worked and called up the video of the Sun brothers coming in and out that day. The video shows that after the two brothers of the Sun family walked in. I went up to the 20th floor of the elevator, and there are 30 floors in this building. The elevator only goes to the 20th floor, and you have to climb the stairs to go up. And the monitoring is only up to the 20th floor, and there is no monitoring on the upper floors. Because some CEOs want to have their own private space, they don't have surveillance. Jiang Chonglang found that there were many flowers on the windowsill of each floor. Among them were azaleas and moon flowers found on Sun Baohe's body.

Jiang Chonglang came to the place where Wang Lulu worked before his death and asked about the colleagues who Wang Lulu used to work for. It can be seen that for Wang Lulu, her former colleagues generally do not have a high opinion of her, so everyone does not feel too sad about her death.
