Through the autopsy, the forensic doctor determined the exact time of Su Muqing's death.

The digestion of food residues in the stomach shows that the deceased should have eaten dinner at around 6 p.m. that day, and the time of the murder should have been around 10 p.m.

If this is an ordinary theft and homicide, the time of the crime should be around the middle of the night, and as a burglar, he will not clean the room, which is too unreasonable.

At ten o'clock in the evening, it was still very lively for S City, which is known as the city that never sleeps, so Jiang Yanxuan believes that it is more likely that this case is still a vendetta.

But for Jiang Yanxuan's idea, the deceased's mother Guo Qian did not agree.

Guo Qian sat on the sofa at home, wiping her tears painfully, she and her husband only raised such a daughter when she was over half a hundred years old, Su Muqing has always been the treasure of the two of them, and after learning the bad news of her daughter, Su's mother's hair turned white overnight.

"Vendetta? No way, my daughter has never had an enemy. ”

Su Muqing's mother Guo Qian has superb embroidery skills, and is the intangible genetic person of the Yao family's embroidery.

"I just treat her as a key cultivation object like an inheritor, and now that she is gone, I am left alone, so what can I do......" Jiang Yanxuan handed her another piece of paper and asked her to blow her nose.

Guo Qian regarded Su Muqing as a key training object, and now that Guo Qian is dead, her wish has been disappointed, and Guo Qian can't figure out who will be her daughter's enemy.

Lin Hui on the other side also screened the social relationship between Zhao Jun and Su Muqing, and they all had witness testimony with conclusive alibi.

Jiang Yanxuan finally decided to set her sights on the deceased's husband.

When they arrived at the scene of the crime, the husband of the deceased looked very calm, could it be that he knew about this matter in advance, so he seemed so calm and relaxed.

For this speculation, Su Muqing's mother was even more unacceptable, in her eyes, her son-in-law was a considerate, gentle, and empathetic person.

Zhao Jun is very good with Su Muqing, and he cares about her on weekdays.

Su Muqing is not in good health and eats less on weekdays, so he will patiently persuade her to let her eat more.

Zhao Jun's motive for killing Su Muqing can be said to be none.

Jiang Yanxuan also inquired that Su Muqing had a failed marriage, and the year before last, Su Muqing and Zhao Jun, who was a driver, met, and soon the two entered the palace of marriage again.

The intimate relationship between the two people after marriage can also be seen from the wedding photos that can be seen everywhere on the walls of the two people's marriage room.

However, Jiang Yanxuan still felt that there was an indescribable abnormality in Zhao Jun.

When they got home from work in the evening, the two discussed the case at the dinner table as usual.

"For now, Zhao Jun is the first person to discover the scene of the crime, and he is also the person who called the police, and he is the first suspect to walk into our sight." Jiang Yanxuan picked up the vegetables that Lu Guan had picked up back into his bowl, and warned him with his eyes not to be picky eaters, "On the day of the crime, he said that he went to see a doctor in other places, so he didn't have enough time to commit the crime, but despite this, I still think this person is very suspicious." ”

"But you can't produce evidence now, can you use your man's sixth sense to arrest people?" Lu Wan ate the green vegetable with a displeased face.

"Let's make a simple assumption." Jiang Yanxuan proposed.

Lu Wan nodded in agreement, the two of them thought about the problem together, and analyzed it from different angles, there would be unexpected results.

"Do you think it will be Zhao Jun, who behaves very well in front of his mother-in-law on weekdays, but often quarrels with his wife in his life."

"Gradually, he even had the idea of killing his wife?"

Jiang Yanxuan nodded: "I don't rule out this possibility." ”

"In the year of the crime, Zhao Jun lied that he was going to see a doctor in other places, but he did not leave, but was hiding not far from the community to observe the movements of the family, at night, his wife came back from outside, and then he also returned home, and then took advantage of his wife's unpreparedness, attacked his wife behind him, and after killing someone, he dragged his wife's body into the closet."

Lu Wan then said, "Then he carefully cleaned the ground, and messed up the things in the house, and after creating a robbery and murder case, he put the mobile phone and jewelry in his wife's hand? ”

Jiang Yanxuan took two large mouthfuls of rice and nodded violently in agreement, "Yes, that's it!" Ah Wan is smart, just a little bit of understanding. ”

Lu Guan stretched out his hand and flicked Jiang Yanxuan's brain, "If only it were really that simple, if your imagination is so rich, just write a novel." Let me ask the simplest question, why did a newlywed couple do this? What benefits does he get? ”

"It's not clear yet, and that's what gives me the most headache."

When people do something, they are all based on the benefits that this thing will bring to themselves, and people will not choose to take the initiative to do things without benefits, Zhao Jun In the case of Su Muqing's murder, the motive and interests have not been found so far, so their idea can only be an idea forever, without any practical significance.

Soon, Jiang Yanxuan's migraine became even more serious.

The next morning when I went to work, the little policeman in charge of the surveillance side came with unexpected news.

The surveillance footage shows that on the night of the crime, Zhao Jun wandered around the streets of Beijing Road at around 7 o'clock, and the most critical point is that the waiter at the hotel where he stayed can really confirm that he was in the hotel at about 10 o'clock on the night of the crime, and he also talked to the waiter.

Beijing Road is a famous commercial street where Zhao Jun went to see a doctor, and that place is more than 100 kilometers away from Zhao Jun's house, so it can be seen that Zhao Jun did not have the time to commit the crime.

However, just a few days after Jiang Yanxuan and them ruled out Zhao Jun's suspicion, Su Muqing's mother Guo Qian called Jiang Yanxuan and them.

"A manager from an insurance company came to me, showed me something, and asked me if it was signed by my daughter. Then I compared the handwriting of the letters that I usually write, and found that this handwriting was unexpectedly different. Su's mother said.

It turned out that Su Muqing had run a high-value insurance before her death, roughly if she had an accident, she would receive 300,000 yuan in compensation, and the policyholder and the ultimate beneficiary were both the informant Zhao Jun.

In other words, the biggest beneficiary of Su Muqing's death is him.

This clue made Jiang Yanxuan very excited.

However, the appearance of the high-value insurance policy can only prove that Zhao Jun had the motive to kill his wife, but Zhao Junyou has already proved that he was not at the scene of the crime on the day of the crime and did not have the time to commit the crime.
