The policeman was stunned for a moment. He was obviously frightened by the excited reaction of the captain. He quickly replied, "yes, but he just called Longteng security people to work well, and informed them that he would go to inspect in a few days. He didn't explain anything else."

The captain sighed. He thought he had got some useful clues, but he just arranged work.

"What about the other phone?" his face darkened.

"Another call was to call the 4S store and drag his smashed taxi away for repair."

"Well, what about the other groups? The captain continued with a frown."

"There are no problems in Times Square. The monitoring shows that Su fan spent the afternoon in the mall after buying his mobile phone that day, and then went to the wine shop to drink. The time and schedule are right, there is no problem."

"We investigated the monitoring of Su fan's residential area and found nothing. As he said, we went home once on the way, and then didn't go back until we finished drinking in the evening. We never came out again."

"Have you seen the monitoring around the villa where Su fan lives? And the monitoring of several other doors in the community?" the captain still doesn't give up. Does Su fan really have no flaws?

"I've seen it all, and I didn't find anything unusual."

They have now fully mastered Su fan's whereabouts that day, and there is really no time to kill.

The meeting room fell into silence again.

Everyone's face was full of sadness. Looking at the results of investigation and evidence collection, they had no clue.

A crisp knock on the door broke the silence in the conference room.

"Come in." the captain's voice was a little hoarse.

"Captain, this is the autopsy report just delivered." a policeman handed over a brown paper file bag.

The captain took the report, took out the documents and looked at them carefully.

The players' eyes turned to him, eager to know if there would be any new findings in the autopsy report, which could help them break the current deadlock.

At that time, the forensic medicine came to the scene of the crime, preliminarily examined the body, determined the time of death, and analyzed that the cause of death may have been hit on the head by a blunt instrument.

Then the body was transported back to the examination center. The forensic medical examiner further examined the deceased and found that the wound on the back of the head was not a knife wound, nor did he find debris such as glass slag. Therefore, it is very likely that he was killed by blunt metal instrument, and he was killed by one blow.

In addition to the fatal injury in the back of the head, there are many marks of being hit on the body, which may be the same blunt instrument as the fatal injury in the back of the head.

In addition, there are broken skin and medicine rubbed on the throat, such as pinched marks, and there are many scuffle marks on the upper body, but the time of the wound is relatively early.

The clothes, skin, hair and other parts of the deceased were not found to belong to the trace of the deceased himself.

The autopsy report also verified Su fan's testimony. He had a fight with the dead in the morning. Presumably, the earlier wound should have been left at that time.

"But the murderer did it cleanly, leaving no trace." a small policeman sighed silently, which added a lot of difficulty to their investigation.

"But we haven't even found the murder weapon yet." maybe we can find the murder weapon. After all, it's something the murderer has touched. If the fingerprints are left and haven't been cleaned up, the case will be solved.

"We have to search carefully around the crime scene to expand the scope, at least find the murder weapon first."

"I think it's possible that the murder weapon has been taken away by the murderer." another policeman immediately pierced his delusion. If it had been left at the scene, it should have been found long ago.

"Yes, he didn't leave us a clue at the scene. I'm sure he won't leave the murder weapon at the scene for us to find. Even if he finds the murder weapon, there will be no useful clues such as fingerprints."

There was a heated discussion in the conference room. Everyone was a little depressed about the case, and the results provided by the autopsy report were not very helpful to the progress of the case.

What should I do now?

The captain held the autopsy report in his hand, thought about it, and said, "divided into two teams. One team continued to investigate the scene, expanded the search scope, and searched the surrounding area and the lower reaches of the lake to see if there was any hope of finding the murder weapon or other clues."

"The other team, starting from Su fan's interpersonal relationship, checked all the people related to him, and carefully screened the dead and other enemies."

"Move!" after the assignment, the captain gave an order, all the police shouted "yes", and ran out of the conference room.

As long as the murderer is still at large, the people's police will race against time to find out the real murderer.

"If what Su Fan said is true, he saw the dead for the first time yesterday morning, then check the people Su fan contacted after that." the captain thought for a moment and continued: "you go and make a list of the people he may contact and investigate them one by one."

"Yes." the policeman took the order and hurried back to work.

Su fan only has close contact with his didi driver brother.

The two police officers came to the old house again and asked the boss to retrieve the surveillance video of the store that day. They found out all the didi drivers who drank with Su fan last night and investigated them one by one.

The result is still nothing.

"There were five people drinking together, all men, who had the strength to hit the dead with a blunt instrument to death. But they didn't have time to commit the crime. Three of them left and drank in a bar until the early morning. Two of them were drunk and were picked up by their wives. They had witnesses and were monitored by the community."

The captain listened to the police report and fell into meditation again.

After a while, he said, "has Su fan checked the communication on his mobile phone number?"

"Yes, there's no problem. I didn't call, send text messages and emails, use social platform software, and check the accepted addresses. There's nothing suspicious."

"Has the deceased made any other enemies recently?" the captain fell into a deep thought. Does this case really have nothing to do with Su fan? Who is the murderer?

"Yes, Zhao Ba has been living in seclusion these days, and his neighbors haven't seen any enemies come to him. I found a pile of information about Su fan in his home. I should really want to find him for revenge." the police officer has some helplessness. If Zhao Ba wasn't killed, I'm afraid he would have to stay in the Bureau for two days.

The captain turned his pen in his hand, his eyebrows locked, and his dark circles became deeper and deeper. He suddenly said, "there's Longteng security company... Have you confirmed it?"

"Captain, do you doubt Longteng security?" the police officers were really shocked when they heard about Longteng security. They are known in the industry for their strict discipline and their strength can not be underestimated. Such a company with deep foundation should not do such illegal things.

The captain sighed and made a phone call in person to negotiate with Longteng security. The result was expected. Su fan really just arranged his daily work.
