In most cases, the bathroom is the first choice for indoor murder. Because blood stains are easy to clean up, just rush the shower, and the walls are tiles. Don't worry about blood splashing on the wall.

Put down the survey box, Qi Yan arranged the Rominor reagent on the spot.

"No fluorescent reaction?"

Qi Yan was not surprised, Zheng Shuyun sang, "My door often opens, and open arms and wait for you."

It can be ruled out that the bathroom is the scene of the crime.

Remove the shading cloth of the window to retract the survey box, Qi Yan entered the kitchen again.

The kitchen is also a high incidence of indoor murder, because blood stains are well covered, and many suspects do not know that forensic doctors can quickly learn from other people's blood and animal blood. They often think that even if they are discovered, they can also be said to be a pig who cooks meat and meat.

Blood.

Qi Yan was made in the same way, but there was still no breakthrough, but a small amount of fluorescence reactions were found around the cutboard and the case.

The master bedroom, the second bedroom, the study, the balcony, all the rooms have been investigated one by one.

Zheng Shuyun's house was very clean, and the furniture was also very particular. There was no messy trace of fighting.

After checking for two hours, each gap was not let go, and there was still no harvest. Qi Yan could only give up.

"How?" Zheng Shuyun asked with a smile: "Nothing must be found? My mother couldn't do the crime. She only returned at noon the day before yesterday. How could she kill Du Ang?

Qi Yan feels that he is provoking.

Keeping calmness, he converged the sharpness of his eyes: "Thank you for your cooperation, please guarantee that the communication is smooth in the near future. We may contact you at any time."

"Good good." Zheng Shuyun still smiled: "Are you leaving? Do you want to leave a piece of meal?"

"No." Qi Yan didn't return, led Laochi downstairs.

At the foot of the building, he also saw two familiar faces. It is estimated that the Ji team sent to the end. Qi Yan did not say hello to them.

In the car, Lao Chi couldn't sit still: "What should I do now? There is no evidence. Is it really necessary to put Zou Jingyi tonight? Damn, I want to hammer him if you look at him!"

Qi Yan: "Then you just talked to him?"

"I don't get used to their boss, let's talk about it, don't conflict!" Lao Chi refuted, followed by calling the firefighting friends, and asked them to check the company's fire protection facilities in a few days, but after finishing these

Still not to alleviate the feeling of aggrieved: "Are there no way now?"

"Of course not." Qi Yan's eyes burned: "We still have a chance, suitcase."

"Well ..." Lao Chi was a little irritable: "Where to find this, who knows where the suitcase was hidden by them."

"You didn't understand what I meant," Qi Yan signaled him to be a little safe: "We don't need to find the suitcase for the time being, just find the evidence related to Zheng Shuyun related to Zheng Shuyun.

Zheng Shuyun had a sixty -inch suitcase enough to stuff the corpse. Zou Jingyi brought the suitcase to the scene of the crime. There was only such a suitcase under the elevator under the floor.

, The suitcase is gone, detaining them but not.

Wait for Xiaoyu again. Although she is young and has not experienced experience, she is indeed a very good criminal policeman.

Lao Chi nodded.

"Moreover, there is a problem of transportation," Qi Yan continued: "Zou Jingyi couldn't carry the corpse in the closet, not enough strength, and time was not enough. At that time, Zheng Shuyun must be on the scene.

Still driving by yourself, there will always be traces to follow, no workload is large. "

"As long as he crimes, he will definitely show your feet."

The two of them thought about things.

After more than ten minutes, Qi Yan received a call from Jiang Xiaoyu. After he connected, he opened the door and asked: "Have good news?"

"Well," On the other side of the phone, Jiang Xiaoyu's voice was very excited: "I found that suitcase!"

"Oh?" Qi Yan and Lao Chi suddenly came in front of the phone.

"Such a large suitcase is rare. He still bought a niche brand. I compiled a program search. After limiting the brand and size, I found that only seven stores on the entire network were selling.

There is only one store that sells this suitcase, or offline trading of local stores. "

"Where is that shop?"

"Just in Okuka Plaza, I have already called them. Their boss told me that the transaction time was six days ago.

The boss sent me the surveillance. Although the trader was wearing a mask of a peaked cap, he could correspond to the height and weight and Zheng Shuyun. I checked the traffic probe and found that at the time Zheng Shuyun drove to Okuka Plaza.

When the wind glass was taken, he wore the same peaked cap and masks. "

"Well!" Lao Chi shot the steering wheel: "Wait for a while to catch someone as one of me, Lao Tzu wants to see when the grandson can be installed!"

"It must be that he will not be wrong." Qi Yan was also a little excited: "This is good, the procedures are legally compliant, without leaving flaws. You ask the boss's store address, and let the Ji team immediately send someone to the scene to obtain evidence.

"

"Okay, I told the Ji team, he has sent someone to Oko Plaza to obtain evidence. Can we call Zheng Shuyun back now?"

Qi Yisi said after a while, and said, "I'm not in a hurry for the time being. When I came out, I saw our brothers downstairs. The Ji team had sent someone to watch him. He couldn't run.

You call Ji team to talk to Zou Jingyi and say that we found that his son had bought a suitcase. Zou Jingyi was in his heart, and there was a probability that he would take things on his body to see if he could ask the position of the suitcase. "

On the other side of the phone, Jiang Xiaoyu stared at his eyes: "God, the Ji team also think so, do you two discuss it?"

"It's just a very direct interrogation idea, you know if you do it too much."

He was not a little bit of a few months ago. After many interrogations and inquiries, although he was far less than Ji Chengpeng in terms of details and timing, he was not much worse than Ji Chengpeng.

Each has its own Qianqiu.

I didn't talk too much with Jiang Xiaoyu, he looked at Lao Chi, who was up: "What is shaking? Drive well."

Lao Chi smiled, raised his hand to open the multimedia, and put on heavy metal music.

Several directions were checked into the wall, and now I finally have the direction. Lao Chi now even wants to sing a song.

Qi Yan resisted the impulse to close the song, silently put on his Bluetooth headset, turned on the noise reduction mode, and did not listen to it.

After more than ten minutes, the Criminal Investigation Division arrived.

When I got out of the car, I saw Jiang Xiaoyu standing in the distance and beckoning hard. She trot all the way, knocked on the window and said excitedly, "Zou Jingyi recruited! Hurry up, let's go now!"
Chapter completed!
