He Jiahui handed a cup of coffee to director Xue Chaohui and said at the same time; "Mr. Xue, don't be nervous, about the case of Zheng Jiazhen's murder, do you know who the murderer is?"

"Yes, the murderer is Cai Mulin!" Xue Zhaohui said with an affirmative face.

"Cai Mulin, is that the cameraman of your crew?" He Jiahui then asked, "Why do you say that he is the murderer?" ”

"Because Cai Mulin has a motive to kill Zheng Jiazhen!" Xue Chaohui paused in his voice and continued; In addition to being a videographer, Cai Mulin is also a somewhat famous photographer.

But he is very lascivious, and often tricks girls to shoot some large-scale photos in the name of helping him shoot photos for free, and even tricks girls into having a relationship with him.

Zheng Jiazhen is one of the victims, more than three years ago, when Zheng Jiazhen was a part-time model, she was also deceived by Cai Mulin to take a photo, and she was also tricked into bed by Cai Mulin.

At that time, Cai Mulin said that he knew a lot of producers and had the resources to let Zheng Jiazhen act in movies, Zheng Jiazhen was not deeply involved in the world, so he believed it, and later Zheng Jiazhen learned that Cai Mulin had no resources at all, he was a liar. ”

"How do you know that?" He Jiahui asked.

Xue Zhaohui opened his mouth and replied, "It was Cai Mulin who told me personally. Before taking this advertisement, I had dinner with Cai Mulin, and I told him that I had found a model with a very hot body as the heroine this time, and he asked me who I was, and I told him that he was Zheng Jiazhen.

When he learned that the heroine of the advertisement was Zheng Jiazhen, he boasted to me that he had a relationship with Zheng Jiazhen, and then told me everything about three years ago.

It was also for this reason that I thought Zheng Jiazhen was a more casual model, so I drank too much that night, so I harassed Zheng Jiazhen with the strength of alcohol, and then I was slapped by her. ”

"According to what you say, it was Cai Mulin who deceived Zheng Jiazhen, and it was Zheng Jiazhen who suffered, then it must be Zheng Jiazhen who resents Cai Mulin, and it stands to reason that Zheng Jiazhen wants to seek revenge on Cai Mulin, right?"

He Jiahui continued: "Cai Mulin is the one who took advantage, since he took advantage, he should not have a grudge against Zheng Jiazhen, and it is unlikely that he will kill Zheng Jiazhen, right?" ”

Xue Zhaohui continued to explain: "This is because three years ago, when Cai Mulin took a photo of Zheng Jiazhen, he also persuaded her to take a set of photos with a very large scale, which was more than enough to be used as a cavalry cover.

After I was slapped by Zheng Jiazhen that day, Cai Mulin showed off those photos to me again, saying that as long as he had these photos in hand, he could let Zheng Jiazhen open a room with him at any time.

Later, on the first night we came to the island, Cai Mulin probably slept alone and was lonely, so he took those photo photos and went to find Zheng Jiazhen, and the two also had a quarrel, the sound was very loud, and the whole B&B could hear it. ”

"In other words, in addition to you, Chen Weiting, the assistant of the crew, also heard it?" He Jiahui asked.

Xue Zhaohui nodded: "We were all in our respective rooms at the time, if Chen Weiting was also in his room, he would definitely be able to hear it." ”

"What are Cai Mulin and Zheng Jiazhen arguing about, do you hear?" Ho Ka Fai then asked.

"I didn't listen carefully, probably Cai Mulin wanted to threaten Zheng Jiazhen with those large-scale photos, saying that if Zheng Jiazhen didn't spend the night with him, he would post the photos on the Internet. And Zheng Jiazhen asked Cai Mulin to hand over the negatives, otherwise he would call the police and shake out all the ugly things about Cai Mulin. Xue Chaohui replied.

"Ugly? What does that mean? He Jiahui asked again.

Xue Zhaohui shook his head: "I don't know exactly what it is, but Cai Mulin is lustful and has a poor character, so he should have done a lot of immoral things over the years."

There are rumors that he seduced underage girls, and there are also rumors that he drugged models, but these are all rumors, I just heard about it, and there is no evidence. Maybe Zheng Jiazhen knows something inside! ”

"Why didn't you say these things when you first recorded a confession?" Ho Ka Fai then asked.

"More is better than less!" Xue Chaohui continued with an innocent face: "And I was also worried at the time, the police found out that I stole money, so I wanted to leave as soon as possible after recording my confession." Later, I heard that your police said that it was an acquaintance who committed the crime, and after thinking about it carefully, I realized that Cai Mulin was the murderer! ”

Xue Chaohui was very sure that Cai Mulin was the murderer, but on the night of the deceased's murder, Cai Mulin had an alibi.

"Maybe it's time to re-examine Cai Mulin's alibi." He Jiahui said secretly in his heart.

……

Cai Mulin's camera is still in the police station, and Liang Bao will connect the camera to the computer again.

Ho Ka-fai sat down at the computer and began to check the time when the photos were created one by one.

Liang Bao said: "I have seen the creation time of these photos, and there is no problem. Between two in the morning and four in the morning, Cai Mulin has been taking pictures on the northeast shore, and he simply does not have time to go to the homestay to kill people. I think it was Xue Chaohui who deliberately said that Cai Mulin was the murderer in order to reduce his sentence! ”

Ho Ka Fai did not answer, but continued to check the creation time of each photo.

As Liang Bao said, between two o'clock in the morning and four o'clock in the morning, Cai Mulin took a lot of photos, which means that during this period, Cai Mulin did not leave the shooting location at all.

"This photo was created at 2:10, this one at 2:13, this one at 2:21, this one at 2:27...... Hey? ”

Suddenly, He Jiahui found a problem, multiple photos in a row, the creation time displayed has the same place, that is, the position of "seconds", and the display is "01".

For example, at 2:10, the creation time is 02:10:01, and at 2:13, the creation time is 02:13:01.

"No, there's something wrong with these photos!" Ho Ka-fai checked the photos taken after half past two, and the situation was the same.

Until 4:20, all photos created during this time period show the position of "seconds", which is "01".

He Jiahui looked at the number of the photo again, counted the numbers, and then showed an expression of sudden realization.

"I see! These photos were not taken by Cai Mulin himself, but with the camera's time-lapse shooting function! He Jiahui said.

"Time Lapse? How do you see that? Liang Bao asked.

He Jiahui explained: "If you look at the creation time of these photos, the second position is all 01 seconds, if you are a photographer, will you be stuck in the first second of every minute every time you press the shutter?"

If only two or three photos are like this, it can be explained by coincidence, but the dozens of photos here are like this, and it is certainly not a coincidence. Even if the photographer deliberately jams the time, it is impossible to accurately get each shot stuck at 01 second.

If you look at the number of these photos, the one at 2:10 is IMG-3402, and the next one at 2:13 is IMG-3405, and the number is three numbers different and the time is three minutes apart.

At 2:21 a.m., the number of the photo is IMG-3412, which is seven digits different from the previous one, and the shooting time is exactly seven minutes.

If I'm not mistaken, Cai Mulin has set up a one-minute automatic shooting function, and every minute apart, the camera will automatically take a photo.

And because the camera's imaging system has a delay, the generated image will be one second slower than the time to take the picture, and the position of each photo will appear in seconds, and it will show 01 second.

After that, Cai Mulin deleted some photos that he was not satisfied with, that is, those with missing photo numbers. The reason why he did this was to avoid being detected by us, and he was using a one-minute time-lapse shot. ”

Guan Gong also came over, and then pointed to the photos in the computer and said: "Jiahui, your speculation is wrong, if the person is not there, but sets up the camera and uses timed shooting, then the shooting angle of all the photos should be the same." But if you look at these photos, it's obvious that the angle has changed, and it's clear that someone is adjusting the angle of the camera, right? ”

Liang Bao next to him also said: "That's right, I just saw that the angle of each photo was different, so I didn't suspect Cai Mulin." ”

Ho Ka-fai replied; "There is a kind of photographic equipment, called an electric remote control stand, some can rotate 360 degrees, some can adjust the height of the upper and lower levels, and some can even set a track route in advance.

The electric slide rail and the 360-degree rotating bracket are enough to shoot different angles. In addition to being a videographer, Cai Mulin is also a photographer, he should be very familiar with this kind of professional equipment, and he can use this way to create an alibi!

Those photos deleted by Cai Mulin should still be able to recover, if we restore all the photos inside, and then arrange them according to the number, we will definitely be able to find the relevance of the photos. ”

"In other words, these photos of Cai Mulin were probably taken when no one was around, so Cai Mulin's alibi was forged by himself?" Seki asked.

"That's right, so we need to call Cai Mulin for re-questioning now, and we also have to search his luggage, and if we find something like an electric bracket or slide rail, we can find evidence that Cai Mulin deliberately forged an alibi!" He Jiahui replied.

……

He Jiahui, Du Xiaohe, and Taishan came to the homestay again, and this time he wanted to take Cai Mulin away for questioning.

"This is where Mr. Cai lives." Aunt Xian, the owner of the B&B, pointed to one of the rooms and said.

He Jiahui stepped forward, knocked on the door, and said at the same time, "Mr. Cai, are you there?" We are the police. “

However, there was no response in the room.

He Jiahui leaned on the door and listened, but did not hear the slightest sound, so he spoke; "Aunt Xian, open the door, let's go in and have a look."

Aunt Xian immediately took out the room card and opened the door of Cai Mulin's room.

Cai Mulin was not inside, and the room was empty.

Not only that, but in addition to the absence of people, even the luggage is gone.

"Aunt Xian, didn't Cai Mulin carry any luggage?" He Jiahui immediately asked.

Aunt Xian immediately replied: "Why didn't he bring any luggage, just count the luggage he brought, two big boxes, saying that there are shooting equipment inside." ”

Du Xiaohe looked at the empty room: "There is no suitcase in the room at all, so he moved all the luggage?" Could it be that Cai Mulin has already escaped? ”

Taishan opened his mouth and said: "It must be that we arrested director Xue Chaohui and scared the snake." This is terrible, as long as people leave Cheung Chau Island, it will be difficult to catch him again. ”

He Jiahui was very calm, he walked to the TV, reached out and touched the back of the TV, and then said: "The TV is still gentle, he shouldn't have gone far, we will go to the dock now, maybe we can intercept him!" ”

The crowd immediately rode their bikes to the pier, but the ferry had just left.

"It's still a step too late!" Du Xiaohe said with some frustration.

He Jiahui said calmly: "It doesn't matter, if you are on the sea and can't escape, call the marine police and ask them to send a speedboat to intercept it!" ”

……

How is it possible for a ferry to outrun a speedboat from the Marine Police?

Moreover, the police station on the outlying islands was originally under the jurisdiction of the Marine Police Region, and this murder case was also equivalent to the case of the Marine Police, so after receiving the notice, the Marine Police immediately sent a speedboat to intercept it without saying a word.

An hour later, the Marine Police sent the suspect Cai Mulin back to the Cheung Chau Island Police Station, along with Cai Mulin and his suitcase.

He Jiahui put on gloves and then opened Cai Mulin's suitcase.

The box was full of photography aids, and sure enough, I found a telescopic electric slide for shooting, as well as a 360-degree electric swivel stand.

With this set of equipment, coupled with the time-lapse shooting function, it is indeed possible to complete different angles of photography without people.

Immediately afterwards, Ho Ka-fai found a bundle of rope in the suitcase, the color, size and material of the rope were exactly the same as the rope that bound and hanged the deceased.

"Evidence bag." He Jiahui immediately opened his mouth and commanded.

Then he put the rope into the evidence bag, and then said: "The rope that hanged Zheng Jiazhen and tied Zheng Jiazhen's hands and feet is likely to come from this bundle." I'll contact the forensic authorities in a moment and send the bundle of rope for testing.

If the results of the forensic evidence show that the rope found in Cai Mulin's suitcase is consistent with the rope that hanged Zheng Jiazhen, then the chain of evidence is complete, and this bundle of rope can also be used as evidence to convict Cai Mulin. ”

Next, Liang Bao began to check Cai Mulin's computer again.

"Come here, there's something in the computer!" Liang Bao shouted, and everyone immediately came over.

Liang Bao clicked on a folder, which was full of large-scale photos of women, there were seven or eight hundred, which should be Cai Mulin's photographic works.

"Let's find out if there is any of the deceased Zheng Jiazhen." He Jiahui said.

"Okay." Liang Bao nodded, and began to take a quick look.

He Jiahui handed Liang Bao a tissue.

"What do you want to do with my tissues?" Liang Bao asked subconsciously.

"Young man with strong blood, look at this kind of thing, I'm afraid that you will have a nosebleed, so prepare in advance." He Jiahui teased.

"You're not a bloody guy? You're younger than me! Keep it for yourself. Liang Bao snorted coldly and continued his work.

Soon, Liang Bao really found a large-scale photo of the deceased Zheng Jiazhen in it.

In this set of photos, Zheng Jiazhen looks younger than now, and it shouldn't have been taken recently. Since Cai Mulin really has a large-scale photo of the deceased in his hand, it is not impossible for him to threaten the deceased with this. ”

He Jiahui paused, and then said: "Director Xue Chaohui is not lying, and the clues he provided are consistent with the evidence we found. There are all human and material evidence, plus Cai Mulin is in a hurry to escape, it seems that he is the murderer of the deceased! ”
