Chapter 127

Wang Ye opens the trace material evidence extraction box, takes out the mask and gloves from inside, puts them on, takes out a strong light flashlight, checks the room all over, and finally stands up with a sigh. Obviously, all the sheets and quilts in the room have been replaced with new ones. In this case, no evidence can be found.

Seeing Wang Ye sighed, Gongsun asked, "I'll check the surveillance and see if there's any clue?"

In addition to the rooms, other places in high-end hotels are equipped with monitoring equipment, so that customers can easily find out if they lose anything.

Now, Wang Ye is left alone in the guest room.

Although Hou Xin did not verbally admit that Chu Tianhe instructed her to poison Hua Jiazheng, various signs have shown that Hua Jiazheng was poisoned by Hou Xin, and the place where Hua Jiazheng and Hou Xin met is here, so the poison must be in this place.

How would she poison it?

Originally, Hou Xin was not caught. As long as she was taken to Gongsun detective office, such a little girl could easily confess that chutianhe wanted to kill people!

Now I have to find my own evidence.

He carefully recalled the scene seen in the eye of heaven. First, Hou Xin took a bath, and then Hua Jiazheng went to take a bath. Wait, take a bath!

Wang Ye goes to the bathroom, turns on the bright flashlight and shines carefully on the ground.

Sure enough, a gleaming drop of water was found in the corner of the bathroom in the bathroom.

Wang Ye takes out the silver needle and touches it. The tip of the silver needle turns black.

This bright drop of water must be mercury

Wang Ye picked up the camera to take a picture, then took out the vial from the box and carefully collected a little mercury in the corner.

Last night, Wang Ye had a slightly clear idea about the case.

Hou Xin pretends to be kept by huajiazheng. Then every time she comes to the hotel to take a bath, Hou Xin will wash first, then take out mercury drops under the shower in the bathroom, and then let the dead Huajia take a bath.

Because Hou Xin took a bath first, the temperature in the bathroom is relatively high, and mercury can volatilize at room temperature. Coupled with the temperature of steam after taking a bath, the natural volatilization will be faster.

In this way, when Hua Jiazheng went to take a bath, he absorbed the mercury placed by Hou Xin. Although the amount was small each time, over time, Hua Jiazheng contracted chronic mercury poisoning.

This killing technique can't be designed by Hou Xin alone. It must have been instructed by the Chutian river.

"Jingling, jingling!" Wang Ye's cell phone rings. He picks up his cell phone and sees an unknown phone.

Wang Ye presses the answer button, and the people inside speak clearly and neatly, "Hello, it's Wang Ye, Forensic Medicine Wang."

"Yes, it's me." Wang Ye has been threatened and even kidnapped several times. He is frightened to hear the voice of such a cold stranger. He raises his vigilance and presses the recording key.

Domestic smart machines are good and can record.

"I'm Chutian river."

Sure enough, it was the suspect who came here. Wang Ye is a little short of breath.

"Chutianhe, what can I do for you?"

Chutian river is very quiet, the voice is very clear, and there seems to be some echo. Wang Ye listens carefully with sharp ears.

"Don't pretend to be confused. You're very good. You've found the strong international hotel." chutianhe said.

Chu Tianhe knew we had found strong, didn't he!

Wang Ye immediately responded. It's probably the housekeeping manager who informed him.

"Hou Xin is by my side now. You'd better..." before Chu Tianhe finished speaking, a strong interference signal appeared in the mobile phone, and then the mobile phone hung up automatically.

Although they haven't finished speaking, it has shocked Wang Ye. They came to strong at 6:20 p.m. and now it's only seven o'clock. Chu Tianhe has already known it and found Wang Ye's mobile phone number.

Of course, the mobile phone number may have been learned from Hou Xin.

After standing in the guest room for about ten minutes, chutianhe didn't call, but Gongsun rang and Zhang Qing came back.

"Shit, what's the matter with their security department?" Gongsun let sweat all over his head, took a bottle of mineral water in his hand, took a swig and continued, "they said the surveillance video was empty."

Zhang Qingqing also had some doubts. He said: "generally, the records will be kept for half a year. This hotel's practice is strange, but it doesn't violate the law, and we can't punish them."

Wang Ye picked up the trace evidence extraction box and said, "it's all right. I found the evidence. I'll send it to the CDC for inspection early tomorrow morning. Let's go first."

"Did you find it?" Gongsun brightened his eyes. "OK, let's go back first."

Gongsun asked to send officer Zhang home. It was already completely dark. Baisha city was brightly lit under the night sky. The autumn tiger quietly came to the muggy Baisha city. At this time, it was a little cool, and this is the beginning of a busy day in Baisha city.

"Wang Ye, why are you still a little depressed?" Gongsun rang is a detective. His keen observation has long noticed that Wang Ye is in a bad mood.

After finding the evidence, I should feel better.

The car radio station was playing the evening news of central and southern province one day. At this time, only Gongsun rang and him were left in the car. Wang Ye said, "chutianhe already knows us."

"Hou Xin confessed?" according to Gongsun rang's experience as a detective for many years, it's normal for a little girl to confess under such a threat.

Wang Ye replied, "it shouldn't be. He actually knew we were at the strong international hotel. It was obviously told by the people in the hotel."

"I'll go!" Gongsun rang finally changed his face.

"You can't find the monitor. I believe it operates on this side of the Chutian river."

Gongsun rang said, "so although criminal cases make money, the risk is too great."

I always thought I was hiding in the dark and could investigate slowly. Now my whereabouts have been found, and the case is becoming more and more difficult.

Wang Ye is silent, and Gongsun rang is also lost in thought.

Only the bright voice of the announcer on the vehicle radio said: "at 6 p.m. this afternoon, the Central South provincial division of our South China Military Region conducted a small-scale military exercise. The new equipment put into use for the first time are radio communication vehicles, radar vehicles and logistics supply vehicles..."

"Wait!" Wang Ye listens to the radio and feels like he has caught some clues.

"Gongsun rang, can you find out the area where the divisional troops practiced this afternoon?" Wang ye asked.

"Well, why do you want to check this?" Gongsun rang asked, "this is a matter for the army. The army is not under local jurisdiction. Where can I check it!"

"Well, if they want to conduct military exercises, they must also contact the local authorities!" Wang Ye is a little anxious.

Gongsun asked Wang Ye to keep asking this question. He was also a little confused. "Why do you want to ask this?"

"I think I should know where Hou Xin is." Wang Ye looks at Gongsun rang and says firmly.
