Chapter 28 It's time to end
This test report was not from the Third Municipal Hospital, nor even from Baicheng, but was issued by a hospital in the neighboring city.
If the child was Wang Youfu's, she had no reason to go to other cities for examination.
"Zhou Yi, you are amazing. You really hit the nail on the head." Qiao Jiali exclaimed.
"Sister Qiao, there's something else I want to trouble you with."
"Just tell me if you have anything to say."
"Go to the hospital and ask the doctor to check if there are any residual anesthetic drugs in Wang Youfu's blood."
"Anesthesia?" Qiao Jiali's intelligence and experience were clearly far inferior to Wu Yongcheng's. "Do you suspect Wang Youfu was drugged after jumping from the building?"
"No, I'm just guessing for now. Please, Sister Qiao, do as I say."
"Okay, then I'll call my colleagues at the hospital."
Zhou Yi took a deep breath, looked around, and wondered where the murder weapon was hidden.
Before the rebirth, the police conducted a large-scale carpet search, but failed to find the murder weapon.
From the perspective of criminal psychology, Zhou Yi concluded that the murderer was a very cautious and insecure person.
It is highly likely that the murderer has been hiding the murder weapon for many years, because only when it is in his hands can he ensure that it will not be discovered. Throwing it away means that it may be discovered.
Suddenly, Zhou Yi's eyes fell on the wedding photo in the living room.
He immediately walked over and took down the wedding photo.
A policeman saw his behavior and reminded him: "We have checked behind the photos and there is nothing hidden."
"Thank you." Zhou Yi still picked up the photo frame and carefully checked the back of it.
Then he discovered two very shallow marks left by the tearing of transparent tape, about ten centimeters apart.
There was something here!
"Sister Qiao, did Zhang Xinli go out before Wang Youfu jumped off the building?"
Qiao Jiali, who had just finished a phone call, nodded and said, "Yes, I went to the vegetable market to buy vegetables. We sent someone to watch over me the whole time."
"What did she buy?"
"Just vegetables, eggs, meat, and so on. They're still in the kitchen." Qiao Jiali asked curiously, "What's wrong? Did you make a new discovery?"
"She must have kept the murder weapon hidden behind the wedding photo, but our presence today caused Zhang Xinli to panic. She was anxious to get rid of the weapon, so she took the opportunity to move it while she was out buying groceries."
"That's impossible. Our people are keeping a close eye on her. If she had made any move to discard the murder weapon, we would have definitely discovered it."
Zhou Yi put down the photo, walked into the kitchen, and found a few vegetables in a vest bag in the refrigerator. They should be the ones Zhang Xinli bought today.
He rummaged for a while and found a piece of meat on the bottom layer. He opened the plastic bag and looked at the meat carefully.
Qiao Jiali watched curiously from the side and couldn't help asking, "What did you find?"
"Sister Qiao, can you cook?"
"Yes."
"Would you buy this piece of meat? It has little lean meat, a lot of fat, and the skin is thick and tough."
Qiao Jiali frowned and shook her head.
"When buying vegetables, she always chooses fresh ones. When buying meat, she always chooses ones with both fat and lean meat. My mother even likes to ask the butcher to cut off the pig skin so that it is not charged because many people do not eat pig skin," said Zhou Yi.
"But Zhang Xinli, why would you buy such a poor-looking piece of meat under these circumstances?"
This time, Qiao Jiali finally understood.
He clapped his hands suddenly and said, "The vegetable market, the butcher shop!"
Zhou Yi nodded. "Well, if she took advantage of the opportunity to buy meat and used the murder weapon to cut a piece of meat herself to weigh it while the boss was busy, then she could have left the murder weapon at the butcher's stall. The police who were following her at the time wouldn't have thought of this. After all, it's normal for a butcher to have knives."
"When the stall owner finds out when he's closing up his stall at night, he won't take it seriously."
"And it's very likely that this knife will be touched by many people later, and Zhang Xinli won't even leave fingerprints."
Looking at Zhou Yi's calm analysis, Qiao Jiali was a little dazed. Who was this young man? Why did he seem to be more powerful than Captain Wu?
"Xiao Kai, come with me now and go to the market that Zhang Xinli went to today. Do you remember which stalls she bought things from?"
The policeman who had just reminded Zhou Yi nodded and followed Qiao Jiali out.
Zhou Yi stared at the wedding photo placed in the corner. Zhang Xinli in the photo had a calm expression, and seemed like a soulless paper figure.
But Wang Youfu smiled like a flower, as if he saw a beautiful life in the future.
"It's been twenty-seven years. It's time to end it!"
Zhou Yi whispered.
…
After Zhou Yi went downstairs, he told Wu Yongcheng about the situation.
In less than half an hour, Qiao Jiali came back in a hurry.
Seeing Zhou Yi and the others standing by the car from afar, Qiao Jiali raised her hand and gave them a thumbs-up.
"Zhou Yi, you are amazing...you hit the mark on everything you said." Qiao Jiali breathlessly raised the evidence bag in her hand, which contained a palm-sized fruit knife.
"When we rushed over, the butcher was just about to go home and was blocked by us."
"When we asked him, he remembered that when he was closing his stall at night, he did find an extra knife on the stall."
"But he didn't take it seriously, thinking the customer had forgotten about it when buying something and just threw it in the glove compartment."
"But like you said, it's probably difficult to extract Zhang Xinli's fingerprints. The blade is covered in a lot of grease, so it must have been used by many people."
Wu Yongcheng and Chen Yan were instantly cheered up. The most important murder weapon had been found, and there was hope for solving the case.
"Good job, little brat." Wu Yongcheng patted Zhou Yi on the shoulder.
"Get in the car, go back to the police station, and give Zhang Xinli a thorough trial."
"Xiao Qiao, you clean up here. Hand the evidence to Chen Yan and have him do the tests immediately when we get back."
Qiao Jiali nodded and said to Zhou Yi, "I'll tell you as soon as the test results from the hospital come out."
"Thank you, Sister Qiao."
The three of them got into the car, and Chen Yan suddenly laughed and said, "Master, I think your position will soon be lost."
"Bah, he's still young. Don't think you can be complacent just because you've achieved some success."
Wu Yongcheng looked at the rearview mirror and smiled at Zhou Yi in tacit understanding.
The three of them returned to the bureau without stopping, and Chen Yan went straight to the technical department with three key pieces of evidence.
Wu Yongcheng and Zhou Yi came to the interrogation room.
Just one day later, Zhou Yi moved from being interrogated to being the interrogator.
"Zhang Xinli, we meet again." Zhou Yi said.
"Wang...how is my husband? He seemed unwell after coming back from work. Later he said he wanted to eat the food I cooked, so I went to buy him some. I didn't expect..." Zhang Xinli said, covering her face and sobbing.
Zhou Yi said calmly, "Zhang Xinli, stop acting. We've found the murder weapon you hid in the butcher shop."
