After Yue Xingwen returned to Xinghai Building, from the first floor to the 40th floor, he carefully checked all the monitoring cameras inside the building.

The interior of the building was a zigzag structure with the elevator in the middle and corridors in the East, South, West and North directions that were connected to each other and all had large floor-to-ceiling windows overlooking the surrounding scenery.

Some floors had different small studios in each of the four directional corridors, while some large companies would take over the entire floor.

The Minghui Law Firms was so wealthy that it had rented a whole floor on the 40th floor, and each lawyer had a separate office with luxurious decoration, even the elevator had a sign saying ‘40F – Minghui Law Firm’.

The Moonlight Design Studio on the 39th floor was apparently not that rich and only rented rooms in the East corridor. To the West was a private ‘Accounting Firm’, to the South and North was the stylish decoration of ‘Yiren Beauty Club’. The Accounting Firm and the Beauty Club all left work before 10 pm last night, and no personnel stayed in Xinghai Building.

Yue Xingwen found that there were monitoring cameras on the left and right sides of the hall on each floor, and there were also cameras at the corners of the corridor and inside the elevator. The stairwells were on the South side of the building, with one camera on each floor.

On the surface, the building’s interior did not have a monitoring dead zone.

Whether you took the elevator upstairs, or climbed the stairs upstairs, you would be captured by the monitoring in all corners.

There was also monitoring in the stairwell from the 40th floor to the rooftop. As long as they checked the monitoring, they could prove whether what Chen Yueqin and Qi Zhao said was true or false.

Due to the fact that there were too many monitoring videos inside the Xinghai Building last night. All the monitoring information of the entire 40th floors was copied by Captain Lin. The police force had a person responsible for viewing the monitoring, and Ke Shaobin was in the follow-up of this matter.

They pulled out the 39th and 40th floor monitoring highlights to check and found several useful clues——

First, the monitoring of the corridor on the 40th floor showed that at about 8:00 pm in the evening, a takeaway brother delivered takeout to the 40th floor of the Xinghai Building, Qi Zhao went out, took delivery at the reception desk on the 40th floor, turned around and returned to the office, and had not come out since.

Second, in the monitoring of the 39th floor, between 9:00 pm and 9:30 pm, Chen Yueqin went out to get takeout twice, the first time, the takeaway brother carried a cake box, and the second time was the Western food she ordered, which was consistent with her description of ‘inviting Zhou Ziyang to come to Xinghai Building to celebrate her birthday together’.

Third, the monitoring of the lobby on the 1st floor captured the scene of Zhou Ziyang walking quickly into the building with his suitcase at 9:50 at night, and he took the no. 1 elevator to the 40th floor. After 20 minutes, at 10:10 pm, Chen Yueqin carried the cake and the take-out, took the elevator to the 40th floor, and sneakily pushed open the glass door of Minghui Law Firm.

No one knew the internal work field inside the office, and no one knew what happened after that, but it was conceivable that the two should have eaten birthday cake and Western food together, had a sweet birthday, and then sneaked into the restroom to make out. During which Qi Zhao. who was working overtime in the office, heard the movement, and witnessed his crush had an affair with someone in the toilet, and his three views were shattered.

Fourth, at 11:15 pm, Chen Yueqin appeared in the elevator hall again, returned to the 39th floor with an empty cake box and takeaway boxes, threw garbage into public garbage cans, and then turned around to walk into the ‘Moonlight Design Studio’.

She did not come again.

This monitoring could rule out Chen Yueqin’s suspicions. She took the elevator back to the 39th floor at 11:15 pm, consistent with her confession ‘go back to sleep after about 11 o’clock’, and Zhou Ziyang’s death time was at 00:00 am at night. She had an alibi.

Although Qi Zhao had never come out of the office or taken the elevator, there was no need to take an elevator from the 40th floor to the rooftop on the top floor, it must be reached by stairs.

Ke Shaobin and his colleagues pulled out the monitoring of the 40th floor’s staircase as well, and stared intently at the monitoring videos.

There was no light in the stairwell at night, but infrared monitoring could still capture people. This stairwell had not been passed by last night, they played at four times the speed until 11:50 pm, a black shadow appeared in the monitoring video.

Ke Shaobin immediately paused the video and enlarged——

The tall man was wearing black sportswear, it was Zhou Ziyang!

He should be drunk, his steps were a little shaky when he walked, and he climbed all the way to the rooftop, never coming down again.

Ke Shaobin adjusted his glasses, looked back at them carefully, and said suspiciously, “He went to the rooftop alone?”

A colleague next to him said, “It is true that no one else went to the rooftop during last night’s monitoring. If you go to the rooftop, you have to climb up the stairwell on the 40th floor, and this section of the stairs is monitored, so anyone who appears will be captured.”

At this time, Jiang Pingce came over and asked everyone to see the results of the monitoring.

Ke Shaobin cut out these five sections of the monitoring videos related to the suspect and the deceased separately. Jiang Pingce looked at it closely, and his brows couldn’t help but wrinkle slightly, “Chen Yueqin and Qi Zhao’s suspicions all ruled out?”

“Judging from the monitoring, it’s true that Zhou Ziyang went to the rooftop alone.” Ke Shaobin said, “Chen Yueqin returned to the Moonlight Design Studio on the 39th floor at 11:15 pm at night, and never came out again. Qi Zhao took the takeaway at 8 pm in the evening, did not come out of the Law Firm, and did not go to the stairwell leading to the roof on the 40th floor.”

The stairwell on the 40th floor led to the rooftop, which was the most critical part of the case.

The monitoring captured the deceased appearing here and walking up to the rooftop, but did not capture anyone other than the deceased.

So, how did the murderer go? Leaping on roof and vaulting over walls, climbing up the window?

Jiang Pingce took out his mobile phone, typed quickly with his fingers, and sent a text message to Yue Xingwen: “Xingwen, the monitoring ruled out Cheng Yueqin’s suspicions, and found that the deceased went to the rooftop at 11:50 pm, but there was not race of the murderer. Can you see if the murderer can climb up to the rooftop from the 40th floor by flipping through the window?”

Yue Xingwen opened the window, and leaned out to look up—— From the 40th floor to the rooftop, the floor height was about 3 meters, and most of the four corridors in the southeast and northwest had falling windows, there was no borrowing point, and it was not good to climb. It was also difficult to climb from the corner of the building. Because the shape of this building was somewhat special, there was a structure similar to the ‘eaves’ on the top of the 40th floor.

The whole building was like wearing a ‘hat’, the width of the eaves was more than 1 meter, even from the window, stepping on the air conditioning unit installed outside to climb up, the top of the head was a meter wide eaves to block, it was impossible to turn over.

Unless the murderer was a special soldier with professional ropes, hooks and other climbing props.

Qi Zhao, a lawyer, should not have the physical conditions to ‘fly through the eaves and walk the wall’ from the window on the 40th floor.

Yue Xingwen took a few photos of the top floor, sent them to Jiang Pingce and concluded: “I saw it on the spot, and it’s almost impossible to climb from the 40th floor to the rooftop of the top floor.”

The investigation of the case fell into a bottleneck.

All suspects had alibi. In addition, their testimony was exactly the same as the video captured by the monitoring. Liu Lan and Liu Minghui went home and did not leave the residence, Qi Zhao had been in the office playing games, Chen Yueqing returned to the studio on the 39th floor at 11:15 pm, and Chen Xueqin played mahjong all night.

The monitoring clearly showed that Zhou Ziyang walked onto the rooftop alone.

Before and after him, no murderer went up to the rooftop.

How to explain his death?

Captain Lin came over with a cup of coffee, stood behind everyone, folding his arms, and analyzed, “The deceased Zhou Ziyang had a leisure to celebrate Chen Yueqin’s birthday last night, and he had an affair in the toilet, he was definitely not threatened. Normal people can’t behave so calmly when threatened.”

He paused and said, “The suspects who have contact with him have alibis. His death, must it have been murder?”

Jiang Pingce was stunned. “Captain Lin means… it isn’t murder?”

Captain Lin smiled and said, “What if after he made out with his mistress, the wine he drank began to go up. He was a little drunk, he was emotional, he climbed up the roof to see the scenery and as a result, he lost his footing and fell?”

Ke Shaobin thought about it carefully and said in a low voice, “In this case, can it explain the clues found so far? Because of drinking, after the passion with Chen Yueqin, Zhou Ziyang’s brain was not very clear. He made an inexplicable call to his wife, accidentally dropped the mobile phone in the toilet, and then climbed up the stairs next to the toilet to the roof, wanting to feel the wind, and fell?”

Captain Lin nodded and said, “En. At present, this explanation is the most reasonable. Because, in all the chain of evidence, no murderer was found and no one was captured on the rooftop.”

Jiang Pingce frowned and said, “What if the murderer had been waiting for him on the rooftop of the building long ago?”

Captain Lin looked back at him with a smile, “What weather was last night?”

“It rained heavily overnight.”

“So, do you think that the murderer flipped through the window in the rainstorm, flew off the wall and climbed up the roof? Or did the murderer go to the rooftop a long time ago and patiently wait for him for 3 hours in the rainstorm? Then how did the murderer know that Zhou Ziyang would definitely go to the rooftop?”

Captain Lin’s rhetorical question made everyone look at each other.

He continued, “Assuming the murderer sent a message or called Zhou Ziyang, asking him to meet and negotiate on the rooftop. Will Zhou Ziyang, a cautious lawyer, climb the rooftop directly to seek death? As you can see, in the monitoring video, he did not carry that suitcase, which means that the speculation that he was threatened by the murderer and made a secret deal with him, is wrong.”

Several colleagues next to him began to discuss, “Captain Lin has a point.”

“Zhou Ziyang climbed onto the roof by himself, and the possibility of losing his footing and falling is greater!”

“His suitcase money should not be used to deal with the murderer. Maybe he just hides it temporarily, thinking about dealing with it later?”

“If he was threatened, was he still in the mood to celebrate Chen Yueqin’s birthday?”

Jiang Pingce said, “But it was raining heavily outside, and he climbed up to the rooftop. Why didn’t he bring an umbrella?”

Captain Lin said, “This Lawyer Zhou may have a fetish for getting wet and wants to go to the rooftop to get wet to sober up. This is more proof that he climbed to the rooftop voluntarily. If the murderer asked him to negotiate, shouldn’t he bring an umbrella? On one hand, it can cover from the rain, and in case of conflict, the umbrella can also be used as a weapon to protect himself.”

Everyone: “…”

There was no murderer in all the evidence, and the suspects involved with the deceased also had alibi, and captain Lin’s analysis was indeed more rational. However Jiang Pingce and Ke Shaobin came to take the exam, and it was ridiculous if the answer was ‘drunk and fell to death’, they absolutely did not agree with this inference.

Seeing Jiang Pingce frowning and thinking, captain Lin patted him on the shoulder and said, “Xiao Jiang, if you think this conclusion is wrong, you can continue to investigate. However, the police have limited manpower and need to investigate other serial murder cases. The case of Zhou Ziyang’s fall from the building is temporarily put on hold. If you can’t find new evidence of murder within 5 days, the case will be closed as an accidental fall.”

Jiang Pingce and Ke Shaobin looked at each other.

All the previous evidence was the information given to them by the topic.

The real exam only officially began now.

The police force would no longer help them find any clues. How did Zhou Ziyang died? They needed to rely on their own to investigate!
