How did Wang Qing die? The medical examiner did not make a clear statement, but only ruled out the possibility of death caused by trauma. He analyzed that the perpetrator had a "sexual assault" process and was more familiar with the deceased.

After Zeng Jingxian left, Ai Chunguang rubbed his hands and said:

"Based on the scene, I reconstructed and analyzed the entire death scene based on the information provided by Fang and Forensic Doctor Zeng. After I finish speaking, if you have any questions, please ask-

The time period of death is set at 13:00-18:00 on the 13th, about 5 hours. Mainly based on the eyewitness testimony of the boss and his wife. The specific time of Wang Qing's death should be able to be accurately calculated after the autopsy tomorrow according to the passage of the contents of her small intestine.

The place of death was in room 201 on the second floor of the west of the Jixiang Hotel. Next to the osmanthus tree in the courtyard where Wang Qing parked the battery car, it is the associated scene. Due to the bad light at night, all the sites - must be revisited tomorrow!

Technical agents conducted a thorough survey of Room 201. After the initial examination of the body, it has been transported to the funeral home for the next step of systematic autopsy?

The doors and windows of room 201 are intact, and there are no traces of pry damage. The curtains were drawn, and the lights, air conditioners, and televisions were on. The light - it was turned on later by Lao Huang. The man in the gray jacket entered the room, maybe the door was hidden at that time, or maybe Wang Qing opened it? The exclusion of 'he' is a forcible intrusion.

The interior layout is rudimentary. Wang Qing died almost naked on the double bed, leaving only a pair of black briefs on her right thigh; Jackets and underwear are placed on the bedside sofa; Long black leather boots are neatly arranged next to the bed, with the tips pointing outwards and the socks tucked into the boots; The backpack was placed on the TV cabinet, the wallet was in the backpack, and 556 yuan in cash, ID card, and a credit union savings card were all in the wallet. - You can look back and see photos and videos from the scene.

In addition, a pink OPPO mobile phone is under the pillow, and after extraction and processing - it has been handed over to Cheng Da. I don't see the 'battery car' key at the scene?

In terms of physical evidence, we processed the floor of the room and found a variety of shoe prints. After on-site comparison, Wang Qing's leather boot prints have been ruled out. Which shoe prints should be screened in the next step, which are left by the boss and his wife, 120 medical staff, etc.? In order to determine the footprints of the 'Grey Jacket Man'?

Some handprints were found inside and outside the door handles and door panels, and they should be screened like shoe prints? - The hotel room is a public place, there are many people in and out, and the screening of traces and physical evidence - the workload is large, the difficulty is high, and it will take some time..."

Speaking of which, Chunguang stopped-touched the door of his brain?

"What do you think or work suggest about Wang Qing's death? -If you have any questions about the scene, do you want to raise them now? Zhang Juqing said with a cigarette:

Xiao Ai just made an objective introduction to the scene, the important thing is the "analysis opinion" derived from the on-site investigation, he wants to hear it? Ai Chunguang has always been a person who has "unique ideas" about the scene, and he appreciates this very much!

"Think-way..."Chunguang blinked quickly:

"There are four thoughts for your reference: first, the first feeling of the scene, I think it is a sexual assault and homicide case; second, the perpetrator and the deceased Wang Qing knew each other well, and even had a deep personal relationship; The third is that the 'gray jacket man' is suspected of committing a major crime, and the fourth is that Wang Qing's battery car is likely to be ridden away by the gray jacket man.

The next step is to continue the site survey tomorrow; Identify the extracted traces and physical evidence as clearly as possible; After the autopsy is over, the physical evidence that should be sent for inspection - send it in time... That's all for now. ”

In view of the large amount of work on the scene, Cheng Yong, Yang Zhijin and other elite detectives were present, and said the "investigation suggestions".

"Hmm..."Zhang Zhengyi finished remembering - looked up, not very satisfied-

Xiao Ai's technical detective skills are reassuring; The on-site intuition is also very sharp! The only pity is that it will not expand, not to diverge its thinking - to think about how to carry out the investigation in combination with the physical evidence at the scene?

Yang Zhijin understands investigation, especially interrogation, but he knows almost nothing about criminal technology, and his awareness of the scene is also weak. He understands both technology and investigation, and is an ideal candidate for an excellent criminal investigation captain in the eyes of Zhang Ju! The incumbent - Cheng Yong, can only be considered "competent" ...

"Inspector Ren, Ni Yutong, and Lin Chenxiao and I were responsible for the on-site visit, which was carried out along the east and north alleys in front of the hotel. Xiao Linzi and I walked through the North Alley, and according to the residents who have been found, no abnormalities have been found. —Inspector Ren, what about your group? Yang Da reported:

After listening to Lao Mo and Chunguang's introductions, he immediately found a "problem" - his previous interview was not targeted, such as "a woman in yellow riding a red battery car, a man in a gray jacket"? It's a general understanding – how many people are in the family? What is your name? What were you doing that day? Do you know what's going on nearby? How is the owner of Jixiang Hotel? Wait a minute.

The pro-faced beast is now wishing for the meeting to end early, so that he can pay a return visit and go to the alley mouth monitoring? No matter how good the on-site analysis is, how can there be a "probe" to be direct?

"Zhang Ju, Yutong and I visited Dongxiang and quickly found that very few people answered the door, or were at home, and they couldn't ask anything? We immediately changed our strategy—" The leopard glanced at Ni Yutong and continued:

"According to Yutong's suggestion, the two of us walked out of the alley - went to Fenghuang Road to find a 'probe'? Fortunately, the monitoring installed in front of the Phoenix Hotel opposite can seal the mouth of the East Lane!

I learned from the police officers in the station that the deceased was wearing a yellow cotton jacket, and the main feature was 'female, long hair, and wearing a yellow jacket'. Now just saw the '2:30' position in the afternoon. There were two people entering the alley, which matched the characteristics of the target - one on foot and one on a battery bike.

Of course, judging from the situation introduced by Fang, it should not be 'Wang Qing'. When we received a notice to come to a meeting, we arranged for two auxiliary police officers to continue watching..."

"Detective Ren, I sent a message to ask the two brothers, and they have already seen '12 o'clock' back, and they haven't seen the woman in the yellow jacket. I told them to take down the surveillance from 12 noon to 6 pm. -Go back and take a closer look, is there a 'gray jacket man'—" Ni Yutong interjected.

"Good!" After listening to Lao Ren and Yutong's report, Zhang Ju secretly praised:

This is a good agent, willing to use his brain; Both proactive and professional! Lao Ren - experienced and old, Xiao Ni is terrible! With such a group of people, why worry about the case not being solved?

"Zhang Ju, I'm going to tune the video at the entrance of North Alley-" The pro-faced beast stood up with a red face:

The work of the leopard team was fruitful, although "Wang Qing" was not found, but it can be indirectly proved that Wang rode in from the North Lane; The man in the gray jacket came to find Wang Qing, and along the route she traveled—the possibility of entering and exiting the hotel was extremely high!

He Yang Zhijin found nothing during his visit, and because Lin Chenxiao left, he even ignored the "video adjustment" work that Cheng Da asked to do. Compared with the two groups, how can he have the face to sit still?

"You sit down—" Zhang Zhengyi's voice was calm and clear:

While waiting for the meeting, he had quietly arranged for Fang Yunmu to send police officers to monitor the vicinity of the North Alley...

"Zhang Ju, let me talk a little bit. Please instruct again-" Cheng Yong broke the embarrassment and said:

"In the past two days, there was 'Ning Laizi lost contact', and then 'Wang Qing died', all of which are hard bones! A lot of work depends on everyone little by little, and it's very hard - especially Yang Da!

The on-site re-investigation of Room 201, including the 'autopsy', was led by Ai Da. Further on-site visits were conducted by Yang Da; Inspector Ren and Ni Yutong retrieved and watched nearby video materials as soon as possible, and sorted out the activity tracks of Wang Qing and the gray jacket man in order to carry out 'video tracking'? ”

At this time, Cheng Da's mobile phone rang - Zhang Jun called:

He answered—with a look of consternation on his face?

About 5 minutes later, Cheng Yong hung up the phone and said to Zhang Ju:

"Zhang Ju - has a situation that I would like to report to you 'alone'?"

The two walked up the inner staircase jogging platform—

In less than 3 minutes, Zhang Zhengyi almost ran down the stairs and ordered everyone:

"Follow the division of labor according to the process! Fang stayed at the scene - aftermath; Cheng Yong, Yang Zhijin follow me! ”
