The ten suspects who had been identified were all taken to the police station to record statements on the grounds that they had been present at the crime scene on the day the victim disappeared.

Calling so many people to record confessions at the same time made it clear that this was a routine inquiry, and no one had any doubts.

Zhang Xingjie entered the interrogation room and sat down. He Jiahui handed over a glass of water and said with a smile: "Mr. Zhang, are you thirsty after waiting for a long time? Our conditions here are simple and we only have plain water. Let's take a few sips to quench your thirst first."

"Thank you, sir." Zhang Xingjie took the paper cup and took a sip.

He Jiahui glanced at Ma Jun. Ma Jun understood and asked: "Mr. Zhang, we watched the video and found that you went to the building where the crime occurred at 3:20 last Saturday afternoon. May I ask?

What are you doing there?"

Zhang Xingjie thought for a while and replied: "I study computer science. A friend of mine always had inexplicable lags and freezes on his laptop, as if it was infected with a virus, so he asked me to come over and check it out.

We met at about 3:30 on Saturday afternoon in a seminar room on the fifth floor of that building. I arrived ten minutes early. After helping him solve the computer problem, he bought me a drink and we chatted again.

After a while, I left."

"How long have you been chatting, and what time did you leave?" Ma Jun then asked.

"I think we have been chatting for a long time. This friend of mine is an anime fan, and I usually like to watch some anime, so we have been chatting about anime."

Zhang Xingjie paused for a moment before continuing, "It must have been about half past four when I left! The elevator surveillance must have recorded my appearance when I left."

Zhang Xingjie's confession is consistent with the surveillance video in the elevator. The elevator surveillance showed that he left at 4:30.

Ma Jun continued to ask: "Who is that friend of yours?"

"His name is Yang Lixin, and he studies law." Zhang Xingjie replied.

Ma Jun looked at the information in his hand and found that Yang Lixin was also among the suspects who had taken statements this time, so he then asked: "Are you familiar with this classmate Yang Lixin?"

"Actually, we can't say we are very familiar with each other, we can only be regarded as ordinary friends. We will say hello when we meet, and we will chat a few words if we happen to meet each other." Zhang Xingjie said.

"Mr. Zhang is a warm-hearted person. If any ordinary friend asks for help, he is willing to go there personally."

Ma Jun smiled slightly and continued: "You can take your laptop with you. If I were to ask you for help, I would definitely come to your door with my laptop in hand."

Ma Jun has discovered doubts in Zhang Xingjie's confession.

A laptop is not a refrigerator or a large item such as an air conditioner. If you ask someone to help repair your laptop, you will definitely have to bring the computer to your door. How can you ask someone to help repair it and have them come to you on their own initiative?

What's more, the two of them are just ordinary friends.

The two of them have a good friendship, so it is reasonable for them to take the initiative to come to the house. If they are just being a licking dog, it is normal to take the initiative to come to the house to repair the computer. It is a bit strange for them to be ordinary friends who are just acquaintances.

Ma Jun had already begun to speculate that going to repair the computer was just an excuse designed by Zhang Xingjie for his appearance at the scene of the crime, in order to cover up his meeting with the deceased at the same place.

Zhang Xingjie explained: "Yang Lixin, who came to me to repair his computer, has very good grades and is among the best in the entire law school. I heard that the tutor at the law school also admires him. He will definitely be able to enter a famous law firm in the future. It's a big deal."

Probability of becoming a big law firm.

I think it would not be a bad thing if I could have a lawyer friend. Maybe I will need help from others in the future. So I also deliberately wanted to make friends with Yang Lixin."

Zhang Xingjie said it more euphemistically. In layman's terms, he wanted to be a barrister in the future and he wanted to curry favor with him in advance.

Ma Jun nodded silently. The confession given by Zhang Xingjie sounded reasonable, but the evidence available to the police could not prove that he was the murderer.

"Mr. Zhang, thank you for your cooperation. If necessary, we will ask you to assist in the investigation." Ma Jun said.

"No problem, I am willing to cooperate with the police. Sirs, then I will leave." Zhang Xingjie stood up, turned and left the room.

He Jiahui said, "Zhang Xingjie mentioned that Yang Lixin from the law department is waiting outside to take a confession. Let's ask him to come over and see if he can match Zhang Xingjie's confession."

"Okay." Ma Jun nodded, and then asked his men to bring Yang Lixin in.

"Mr. Yang, according to the surveillance video, you went to the building where the crime occurred at 1:30 pm last Saturday. What were you going to do?" Ma Jun asked.

"My laptop seemed to be infected with a virus, so I asked my friend to check it for me. We made an appointment to meet on the fifth floor," Yang Lixin replied.

"Who is the friend you are talking about?" Ma Jun asked next.

"His name is Zhang Xingjie, he studies computer science. Didn't you ask him just now?" Yang Lixin said.

"According to Mr. Zhang Xingjie, the time you agreed on was 3:30 in the afternoon. Why did you arrive at 1:30?" Ma Jun asked again.

Yang Lixin immediately replied: "We have a heavy workload when studying law. In addition to a large number of legal rules to recite, there are also many cases to analyze, so for me, there is no day off. As long as I have time, I will

Will learn.

After lunch on Saturday, I went directly to the agreed place, read a few case studies, and waited for Zhang Xingjie to come over. I didn’t mean to arrive early, I just didn’t want to waste time.”

"What happened after repairing the computer? What did you do again?" Ma Jun continued to ask.

"I went to the vending machine, bought a drink, and then chatted with Zhang Xingjie for a while." Yang Lixin replied.

"What did they talk about?" Ma Jun asked again.

"Let's talk about Naruto. This is a very popular Japanese anime. Sir, have you seen it?" Yang Lixin asked.

"I'm usually busy with work and don't have time to watch anime." Ma Jun replied.

"Oh, that's such a pity. If you have time, sir, you can take a look. It's very exciting!" Yang Lixin transformed into an animation salesman.

Ma Jun didn't want to talk about Naruto, so he asked: "About what time did Zhang Xingjie leave?"

Yang Lixin thought for a while and said, "It seems to be four o'clock!"

"Are you sure it's four o'clock?" Ma Jun asked immediately.

Yang Lixin hesitated for a few seconds, and then said: "I'm not sure. I didn't look at my watch at the time. But I think we didn't chat for a long time, probably less than twenty minutes. Counting the time he left, it was at most

It's four o'clock."

"What happened after that? When did you leave?" Ma Jun asked again.

"After Zhang Xingjie left, I continued to read the case analysis. Maybe I was too immersed in it. I didn't notice the time. It wasn't until I got hungry that I realized that it was already six o'clock in the afternoon. Then I left quickly and took the bus back.

Home." Yang Lixin replied.

Yang Lixin's confession is consistent with the surveillance video. He did enter the elevator from the fifth floor at six o'clock in the afternoon and then left.

After ending their questioning of Yang Lixin, He Jiahui and Ma Jun discussed the case again.

"Zhang Xingjie said that he left at 4:30, and the surveillance in the elevator said the same. But Yang Lixin said that Zhang Xingjie left at 4:00. There is a half-hour gap between the two people's confessions. Is this possible?

When did Zhang Xingjie commit the crime?" Ma Jun asked.

"It's very possible!" He Jiahui nodded: "But Yang Lixin also said that when Zhang Xingjie left, he didn't look at his watch, and he couldn't determine the specific time. Zhang Xingjie can definitely say that Yang Lixin remembered it wrong."

"Yes, the evidence we have so far can only show that Zhang Xingjie is suspected, but we have no evidence." Ma Jun frowned.

"If there is no evidence, look for evidence!" He Jiahui continued: "Let's start with Zhang Xingjie's interpersonal relationships. If he is the murderer and kills three people in a row, I don't believe there is no trace left!"

…

The next day, the identity of the suspect wearing the peaked cap and the two masks were also determined, and the three people were called to take statements.

Ma Jun took the information bag containing the confessions, came to He Jiahui's office, and asked: "All the confessions of the fourteen suspects have been recorded. Do you want to read it again?"

"I'll read it later and send it back to you after I finish it." He Jiahui then asked, "Tell me the results first."

"Through the transcripts, six more people can be temporarily excluded." Ma Jun took out the confessions of three people and continued: "These three people made an appointment to meet on the sixth floor at 2:30, and two of them came together.

, they can testify to each other.

Although the other person came alone, the three of them had not separated since they met at 2:30, and they also left together. The deceased arrived at 2:50, so their time was the same as that of the deceased.

It got sidetracked."

Ma Jun produced three more confessions: "These two people came together and left together. They can prove each other. So I have temporarily ruled out their suspicions.

As for the last one, he is the one wearing a peaked cap. The reason why he wears a peaked cap is because he had a car accident before and had more than a dozen stitches on his head, so he wore a peaked cap to cover it up.

Moreover, during the car accident, his arms and legs were injured. One hand was fractured and he could not hold things, and one leg had a strained ligament. Although he could walk, it was difficult for him to exert strength to climb stairs.

Based on his physical condition, it was impossible to move the deceased from the eighth floor to the rooftop, so I eliminated his suspicion."

"Fourteen minus six, there are still eight suspects left! The one with the biggest suspicion should be Zhang Xingjie, right?" He Jiahui asked.

"Yes, I have asked Uncle Hua to investigate his interpersonal relationships." Ma Jun replied.

At this time, Yang Zai hurried over.

"Sir Ma, good news, the technical department just called. They have been monitoring the mobile phone of the deceased Liu Baorui, and they just found that the mobile phone is turned on, and the location is in Tai Kok Tsui!" Yang Zai said.

At the crime scene, only the wallet and keys of the deceased were found, but no mobile phone was found. Obviously, the mobile phone should have been taken away by the murderer, and the police's technical department has also been tracking the deceased's mobile phone.

These days, mobile phones have positioning functions, and many brands of mobile phones have location tracking settings. As long as the mobile phone is turned on, the police can easily lock the position of the hand through technical means.

Now that the deceased's mobile phone has been located, it is obviously a major breakthrough in the case.

Ma Jun immediately said: "Ask the technical department for detailed positioning, we will go to Tai Kok Tsui immediately!"

…

The final location sent by the technical department was a shop selling second-hand electronic products in Tai Kok Tsui.

Looking at the second-hand electronics store in front of him, Ma Jun snorted coldly.

"Sir Ma, do you know this store?" He Jiahui asked.

"Old acquaintance! The owner of this shop not only collects stolen goods, but also sells parallel imports! I have arrested him many times." Ma Jun said, striding in.

"I must have beaten him many times!" He Jiahui thought to himself, and then followed him.
