Police Chen Shu

Chapter 764 Video Analysis

Chen Shu leaned over, took the mouse on the table, and clicked a few times on the file where "Zheng Amei" was located on the computer screen, calling up the video of the crime scene.

As the screen window was opened, the scene at that time began to play back.

"Brother Shu, what are you watching?" Jiang Hai, as the party involved, saw the video being opened, which was the video of the three of them entering the crime scene for the first time in the hotel corridor, and felt a little strange.

"Conan Shu must have found something at the crime scene." Chen Chuan was not interested in the content of the video, but it did not prevent him from teasing everyone, "Tsk tsk, there are only three of us at the scene, your brother Shu can't check himself, the rest are me and Xiao Hai. Tsk tsk, Xiao Hai, do you think you are attracted by the beauty?"

"Brother Chuan!"

Jiang Hai blushed with anger, but after a few days of getting along, he really had no way to deal with this sloppy senior brother, and he always joked regardless of the occasion.

It is said that in Dongzhou Municipal Bureau, except for the old one and the executive of the Municipal Bureau, this senior brother also teases other police officers and even senior police officers equally.

No wonder he is still a clerk after so many years of graduation!

Jiang Hai was dissatisfied, but what he didn't know was that privately, this senior brother he looked down on was very popular in the bureau.

Think about it carefully, can someone who can tease the deputy director as a friend be an ordinary cow and horse?

Sometimes you can see how others get along with their leaders by listening to the tone and address they chat with each other.

The relationship that can joke is not ordinary, especially Chen Chuan, who can chat as soon as they meet, and even give nicknames to people. That is an incredible close relationship.

Zhu Yiba knows Chen Chuan's nature of liking to tease people. To say that Jiang Hai is a criminal suspect is more false than the sun rising from the west.

However, at this moment, he was the first to react. After all, there was another person at the scene besides the three of them.

Zhu Yiba widened his eyes and said in surprise: "Chen Da, you are doubting the hotel cleaner! The 40-50-year-old lady!"

After Zhu Yiba's reminder, everyone held their breath and stared at the screen repeatedly replaying the scene of the cleaner entering the door and finding the body and then calling for help.

To be honest, none of them could see the trick.

After the video was played several times, Chen Shu called up the hotel corridor video ten days ago, fast forward and out on the progress bar, and adjusted it four times faster, then nine days ago, eight days ago, seven days ago, until the day of the crime.

Finally, Chen Shu, who was straightened up, let out a long breath and leaned back in his chair.

When the other people heard this call, they knew that the backbone had already figured it out, and they all let out a long breath, and immediately felt much more relaxed.

The young Jiang Hai expressed his confusion in person without any face: "Brother Shu, I can't see any problems in these videos."

Zhu Yiba, who also didn't find any problems, frowned and didn't say anything.

Chen Chuan, who had no interest in the case, crossed his arms and watched his old classmate's next performance with interest.

Ma Rongcheng, who was sitting on a chair, grabbed the armrests of the chair with both hands and stood up involuntarily, feeling a little nervous.

For those who are engaged in technical investigations like them, it has been a long time since they have experienced this kind of reasoning and solving cases, but the title of expert made him remain silent.

Chen Shu did not pretend to be mysterious. He first switched the video surveillance to the scene of Zheng A-mei pushing a sanitary cart in the corridor ten days ago.

Click, pause, and then zoom in on the picture.

Chen Shu pointed at Zheng A-mei's hands on the screen and said in a deep voice: "Pay attention to her hands, is she not wearing gloves?"

The hotel camera does not have a high-definition lens. The picture that was intercepted at this moment is relatively blurry. It is not sure whether Zheng A-mei is wearing gloves, but the position of her hands looks like the color of her skin.

Then nine days ago, eight days ago, and until the day before the incident, Zheng A-mei's hands were basically yellow. She passed under the camera several times, but she didn't look like she was wearing gloves.

Thus, it can be roughly inferred that Zheng A-mei did not wear gloves for even a second in the nine days before the incident, and she was cleaning naked.

Then, Chen Shu switched the video to the day of the incident, and then converted the video speed to normal speed.

The corridor was very quiet that day, and only Zheng A-mei was walking in the corridor pushing a cleaning cart full of towels, slippers and other hotel supplies and cleaning tools.

"Hiss! It turned white!"

Jiang Hai took a breath of cold air. The cleaning lady who appeared in the video had a pair of white gloves on her hands!

Zhu Yiba questioned loudly: "What a coincidence? She wore it on the day of the death?"

Huang Mao immediately agreed: "There must be something wrong! This person must be the murderer! Platoon leader, I will go and catch him now!"

Jiang Hai pinched his chin and directly regarded Zheng Amei as a suspect, thinking hard: "Is she not wanting her fingerprints to be left in the room? But it doesn't make sense logically. It feels meaningless. She is a hotel cleaner. It is normal to leave fingerprints in the room?

"But she didn't wear gloves for nine of the ten days she worked, but she wore them on the morning of the crime. It's hard not to suspect that she is the murderer. The secret room is for people who don't have a room card. "

With a snap, Jiang Hai clapped his hands and said firmly: "She is the murderer!"

Chen Chuan was smiling all over his face, but what he said was like a knife piercing the junior brother next to him who was inspiring to become an excellent detective.

"Xiaohai, have you forgotten what our horse expert said?"

Hearing the words of the unreliable senior brother, Jiang Hai couldn't help but feel goosebumps all over his body, and asked in a trembling voice: "What are you talking about?"

Chen Chuan tilted his head slightly and said with a smile on his face: "The nature of the camouflaged shoe prints that appear indoors is that big feet are wearing small shoes. Look at this eldest sister's body shape. Does it look like someone with big feet?"

Jiang Hai was like a deflated rubber ball, suddenly sluggish.

Chen Chuan smiled happily. He liked to see Jiang Hai's ups and downs of emotions. He was so funny, just like Chen Shu when they were still studying in the police academy.

Expert Ma Rongcheng agreed with Chen Chuan's opinion, but what he was even more surprised and admired was that Chen Shu's unique investigative thinking could actually connect these two completely unrelated things.

He subconsciously glanced at the policeman from another province standing beside him. Under the incandescent light, Officer Chen's Chinese-character face was cold and serious.

Chen Shu did not pause the video to explain, but allowed the video to continue playing along the timeline until the deceased's door was opened.

Pressing the space bar with a "click" to pause, Chen Shu then cut the video into a specific timeline, that is, the scene from when Zheng Amei entered the corridor to opening the door, and played it repeatedly.

"Did you see anything?" Chen Shu knocked on the table and asked.

Everyone shook their heads.

After a while, Jiang Hai was the first to react: "It seems. It seems like this cleaning lady has been stalling for time?"

Chen Shu snapped his fingers and affirmed: "That's right! When I discovered this situation, I just thought she was waiting for time. Because during the on-site inquiry, the cleaning lady named Zheng Amei told me that the deceased asked her to I came to clean up early in the morning, so when I saw her grinding and chirping in the corridor, I wondered if she was waiting for the time requested by the deceased. "

"But" Jiang Hai followed Chen Shu's train of thought and explored step by step, "but there is absolutely no need to stand in the corridor and wait. Doesn't this affect the passage of guests? If it is just to wait for time, she can completely wait in the corner. Wait in the grass room, where you can play with your phone while hiding from the camera!”

Chen Shu nodded: "Correct. This is the first doubt. Continue."

Being affirmed by the person he admired, Jiang Hai naturally became more confident and continued to speculate on the reason: "But why is she waiting in the corridor?"

As he said that, Jiang Hai pointed to Zheng Amei's expression on the monitor looking towards the end of the corridor: "I found that she seemed to have been looking in that direction, well, several times."

"Very good." Chen Shu helped Jiang Hai and added, "That direction is where the hotel elevator is."

"Elevator." Jiang Hai murmured, as if there was a firefly floating in his mind. He wanted to catch it, but he couldn't catch it many times. The firefly was still flying everywhere slowly.

Then, Xiao Jianghai in his mind suddenly jumped up and reached out to grab it.

Snap, caught!

"Elevator!" Jiang Hai's eyes shone and he jumped up, "Brother Shu! I know! I know! She is waiting for someone to come! She is waiting for someone to come! This proves that she is just the first person to open the door and enter! Well someone else entered the room at about the same time as her!"

"This is the second point of suspicion." Chen Shu nodded happily, then canceled the repeat playback of the video, and the video started playing at the position where it was previously stopped.

In the video, Zheng Amei opened the room and entered the house with her right hand wearing a white glove, then let out a scream, and then Chen Shu led people into the crime scene.

Chen Shu took this paragraph as the standard and started playing it repeatedly.

"Is there a third doubt?" After the ecstasy, Jiang Hai calmed down instantly, and frowned as he stared at the second video captured by Chen Shu.

This is a scene of only five or six seconds. The content is that Zheng Amei opened the door and entered the room, and then suddenly screamed to attract the three people who came out of the elevator earlier.

By the way, these three people are Chen Shu, Chen Chuan and Jiang Hai who came back from eating mutton soup.

For a long time, no one found the problem.

"Hurry up, Shu, tell me!" Chen Chuan couldn't bear it and urged.

"Time, time is abnormal." Chen Shu paused the video, then pointed at the timeline and said, "When the person entered the room, it took five or six seconds before he screamed. This time is too long."

Jiang Hai, whose eyes were almost attached to the monitor, clasped his hands together and said, "I understand. The body is hanging beside the toilet door. Most people will see the body hanging on the door frame immediately after entering the door! It is impossible to pass six Scream in seconds!”

Ma Rongcheng asked: "Is it possible that after entering the house, the cleaner answered a phone call at the door, or did something similar that we couldn't see on the surveillance, so it was delayed."

Chen Shu finally smiled and said, "I just want to know what she did in these six seconds."
