today's island

If you don't have any clues, just look for it again. It's not like sitting in the special case team and reading mystery novels, but what Sun Yan can find out is not worth it.

In the afternoon, they drove the dilapidated van of the police station and left the task force collectively after a long absence.

Although half a month had passed since the first case, and even the most recent case had occurred for nearly three days, they still returned to the scene.To solve the case, it's not surprising that it's only been less than half a month when I returned to the scene after a year and a half and found new doubts.

"To be honest, these places are far away." Ding Chenyu drove, and Su Xiaozhi sat in the co-pilot and looked at the navigation, muttering.

It was seen on the map yesterday that the locations of the crimes were scattered, but it was too scattered. Lu Yuanzhe, a racing biker in an island city, might not be able to find these locations by the shortest route without relying on navigation.

"This is also an important doubt. He is a fugitive. Could it be that his usual hobby is traveling around island cities?" Lu Yuanzhe continued.

Wanghai Square has completely returned to normal. This is one of the landmark squares in the island city. It is so lively that it is absolutely impossible to block it.Everyone cannot be expected to pay attention to the news every day. Some people don't even know what happened here, and wantonly walk near the fountain where Zhao Pengcheng died.

After flipping through the photos, Cheng Mo stood at the position where Zhao Pengcheng exploded, raised his phone, and took a complete panoramic photo.

"What is this for?" Wan Yi leaned over to look.

"This kind of prisoner who pays attention to performance art likes to stay and watch the whole process of committing crimes." Cheng Mo flipped through the picture.

Half of Wanghai Square is facing the sea, and half is surrounded by buildings in the distance. It is a standard square structure.

"Only the media said it was a performance art, and he ran away after he caught fire on the surveillance footage, so he didn't have the heart to appreciate art." Wan Yi reminded.

"But the dance studio he chose can indeed see the square." Cheng Mo pointed to the dance studio.Although the distance is a bit far, it is not completely invisible.

There was nothing left in the square, they moved to the dance studio.It was still blocked here, and many footprints were circled. It can be seen that both the prisoner and the victim walked around the house several times.Judging from the shoes, the prisoner was about 1.8 meters tall, and he was indeed tall, similar in size to Yan Ye.

"The prisoner seems to have chatted with the deceased here for a while." Cheng Mo carefully walked around the footprints drawn on the ground and stood at the window.

"Then I should really look up." Lu Yuanzhe also noticed it, and stood with him at the window, looking at the fountain on the square, "I was standing on the other side of the fountain, and I happened to be able to see here."

"This is one-sided glass. If you hadn't turned on the light, you couldn't see the inside." Cheng Mo was just about to touch the glass, but was stunned for a moment, "This glass... seems a little clean."

"Huh?" Lu Yuanzhe was stunned for a moment, and then realized that there were no fingerprints or other stains on it. Compared with the traces left in other places, it was indeed ridiculously clean.

"Someone wiped it off." Ding Chenyu interjected, and the trace inspection team also noticed this. "It may be that the criminals stood here to exchange something on the night of the crime in order to eliminate the traces, and then touched the glass."

"The ground is like this, why are you so obsessed with cleaning the glass?" Wan Yi asked in surprise, "As you said, he would definitely wear gloves when committing crimes, and he wouldn't leave fingerprints."

"It's rare to see people who say something secret likes to stand at the window." Lu Yuanzhe also frowned, and casually mentioned something.Although he still can't figure out the reason for this for the time being, he silently made a note in his heart.

Moving to the second crime scene - Huashun Bay, the traces here are much clearer. It has not faded after a week, and it is estimated that it will take a long time to gradually fade away.That night, the prisoner violently poured gasoline from the second floor, splashing everywhere and even blackening the walls.

After being attacked, the deceased did not dare to run in, probably because he could hear the voices and music of the square dance, so he ran in the direction of the crowd.

You can't see the square from the stairs, you have to turn a corner to see it, so none of the square dancers saw any suspicious people.

After all, it is a residential area to be demolished, the properties are left unattended, the monitoring has been in disrepair for a long time, and many of them are not working.However, the surveillance at the gate of the community is still alive, and no images of the prisoners entering or leaving have been captured.

Except for a small number of houses rented to migrant workers, most of them are elderly residents.Judging from Sun Yan's transcript of the questioning, everyone only knew that a stranger had been here. As for who it was, everyone described it differently. There was only one sentence in common - it must be the prisoner who offered a reward, which shows the charm of offering a reward. .

After a field inspection, they found no noteworthy details. The wall was old and somewhat damaged. There were some passers-by taking shortcuts, so it was hard to say where the prisoner had gone.

If it was an ordinary prisoner, even if a lot of surveillance cameras were damaged, he shouldn't be able to hide so cleanly. But this is a felon who has been on the run for many years.

After turning around, they found nothing new, so they drove to the third crime scene.

This is an unusual crime location. As usual, this kind of indiscriminate crime always picks remote and uninhabited areas. Few people choose closed environments. Even if the surveillance fails, it is not easy to sneak in.

Because it happened in the stairwell, the residents basically took the elevator. This crime scene is the best preserved, and it was so intact that the residents panicked and almost dared not go out.

Shown through the door by the property owner, they checked the possible entrances and exits.The transom is too small, and even dwarves can’t squeeze in; you need to swipe your card to enter the door, and you need to swipe your card for the elevator door in the underground garage. Not only do you have to register at the gate of the community for takeaways and express delivery, you can’t enter the corridors, which is indeed very tight security.

Because it has just been built, the nearby commercial area has not been fully developed, and the occupancy rate here is very low. At night, only seven or eight households in the entire unit are lit.Because of this, the deceased ran wildly in the corridor with the fire all the way, wailing and hoping that someone could rescue him, but no one heard him at all.

Although it was not photographed, the traces on the scene showed that the prisoner stuck the elevator on the top floor with a cardboard box in advance.The deceased had no choice but to climb the stairs because he couldn't get an elevator. He was attacked on the third floor and stopped when he reached the sixth floor. Then he rolled down the stairs and landed on the fifth and a half floors.

The fifth floor was half unoccupied. The cleaning staff smelled a strange smell and opened the door of the stairwell to find the body.

"It's terrible." Su Xiaozhi looked at the traces in the corridor, and could imagine the scene of a fireball flying up and down that day, "This prisoner has a lot of mental problems. When it gets up and spreads on the Internet, it can really be called performance art.”

"Fortunately, the whole building didn't catch fire. This structure has siphon phenomenon. If you prepare enough fuel, it is easy to burn from the first floor to the top floor." Lu Yuanzhe commented.

"Yeah." Cheng Mo echoed, "The criminal's modus operandi was very rough in the past. If he had stronger knowledge of chemistry, he would cause even bigger troubles."

"That's not right." Wan Yi frowned and interjected, "The vest worn by the first deceased was full of metal powder that reacted violently with water, and there was an ingenious time-lapse design of water-soluble materials. Doesn't the prisoner understand chemistry?"

"Maybe it's where it came from. It was this that re-stimulated his desire to commit crimes, but he didn't systematically study this knowledge." Ding Chenyu speculated.

"Or there are two prisoners." Cheng Mo added.

"You started to suspect that there were two if one didn't catch you?" Wan Yi was quite nervous about this thought, "Don't scare me, Yan Ye spent a few years cultivating an apprentice?"

"That's not true. Maybe someone will give him some advice. It may not be a two-person crime. It takes courage to kill someone." Lu Yuanzhe shrugged and looked around the closed corridor, "No matter how many people there are, we must find a way to get in."

"There is no sign of violent door breaking, so it must be that the prisoner has a room card?" Ding Chenyu asked.

"But Team Sun has already asked. The residents and the front desk that temporarily issued the key cards have no conditions to commit crimes." Su Xiaozhi reminded.

"The ones that followed or were brought in?" Wan Yi asked.

"The front desk said that the person who didn't have the property borrowed the key card that night, and the residents all said that they were alone." Su Xiaozhi replied.

Wan Yi tilted his head and thought for a while, then suddenly thought of the scene in the movie, and covered his mouth in surprise: "I've been hiding in the corridor for three days, right?"

"Congratulations, the takeaways, express delivery, and cleaning that have been here within three days, as long as they have registered at the door, all suspects have been ruled out. We can only suspect that there is an accomplice, but no suspicious accomplice has been found." Su Xiaozhi spread her hands, " You can’t really wait for the enthusiastic people to report it, can you?”

As the captain, Sun Yan's investigation was hard enough and thorough enough, it would have been better if their eyes were not so teasing.

"That's absolutely terrifying." Thinking about Sun Yan's experience over the past two days, Lu Yuanzhe joked.

Taking the elevator back to the underground garage to drive, standing in front of the elevator door, Lu Yuanzhe looked at it for a while and frowned.

"What's wrong?" Ding Chenyu glanced at him, "It's unreliable to open the elevator door and climb up, we will find traces."

"Of course not." Lu Yuanzhe smiled, shrugged and got into the car.

The car drove out of this community where the security was really conscientious, and when it arrived at the gate, Lu Yuanzhe saw that the guard recorded their license plate numbers again, and it seemed that the police car did not charge them for parking.

"Has the license plate number been recorded for those who drive in and out?" He turned his head and asked Su Xiaozhi, "Has Sun Yan checked to see if there are any strange vehicles coming in and out recently? It may not be the day when the crime happened or the next day, in case the other party is hiding." How long is it?"

"Well, I've checked." Su Xiaozhi nodded, "The criminals' crime locations are so scattered, Team Sun also thinks that they may be driving, but they have seen the owner of the car, and no suspicious vehicles have been found."

People can sneak out, but cars really can't, and there is absolutely no way to smuggle them out.

"Got it." Lu Yuanzhe nodded.
