Cai Wei shook her head vigorously: "I don't know me, I really don't know ......"

Cai Wei said that she was out of the morning, and the people outside stood at her door for about half an hour, and her best friend Chen Xingxing drove back in a hurry from half past twelve, and went downstairs to her house three hours later, about four o'clock.

After four o'clock, accompanied by Chen Xingxing, the two went to the police together to report to the police.

According to Chen Xingxing's description, she parked her car downstairs at four o'clock, and when she went upstairs, she did not see any suspicious people or vehicles.

It's seven o'clock in the morning.

Between half past four and seven o'clock, it is very likely that someone broke open Cai Wei's door, or somehow sneaked into Cai Wei's home, opened Cai Wei's laptop, and deleted the call logs.

So, if the other party is in such a hurry to delete the record, will it be because he knows that Cai Wei reported the case.

I hurriedly asked Cai Wei: "Who knows that you went to the police?" ”

"Only...... It's only Chen Xingxing, and no one else knows......"

"Only her?"

I'm confused.

Chen Xingxing and Cai Wei have been together since they came into contact, and when they accompanied them to the police station to report the case, Chen Xingxing had no time to commit the crime at all, and she also had an alibi.

Compared to the previous cases, this case looks simply mysterious!

At least in all previous cases, we can either see the victim, even if it is a corpse, but if someone is killed, there must be a murderer, and if there is a murderer, we will definitely be able to locate the suspect.

But this time, it seems that everything is foggy! I can't get rid of it at all.

I called Tang Yu and asked her to operate an unfamiliar QQ account on the spot, and after a voice call, can she unilaterally delete the call record on the other party's computer.

Because I am not very familiar with this aspect, I usually don't use this instant messenger except WeChat.

Tang Yu quickly followed my thoughts.

The final result is: "The other party can delete Cai Wei's account, but in Cai Wei's computer QQ, there will be traces of call records, and the other party's chat window cannot be opened, but the other party's nickname, avatar, etc. can be seen on the message list page!" ”

I hurriedly asked Cai Wei, "Do you remember what the other party's avatar is?" What is a nickname? ”

Cai Wei shook her head: "Avatar...... It's like a V-shaped vendetta with a smiley mask, and I don't remember anything else......"

I sat down and carefully checked Cai Wei's QQ boy, rummaging through all the messages inside and out.

The final result of the verification was that between twelve and one o'clock in the morning last night, there was no call log!

Then, it can only be defined as being deleted.

Either the person behind it, sneaked into Cai Wei's room and deleted it personally.

Another possibility is hacker invasion, remotely operating Caiwei's computer and deleting it autonomously.

Our current detection direction is almost a black hole, and we can't even tell which clue is more valuable, or even no clue at all.

The comrades of the trace inspection team at the door were still continuing their work, sweating profusely in a hurry.

I checked around the ventilation windows, exhaust fans, and neighbors' balconies, bay windows, etc., and found that they did not have the external conditions to climb in from the outside.

Tang Yu frowned: "I haven't seen such a pending case." ”

A real **** who had just joined the police force whispered over and asked Tang Yu: "Team Tang, could there be a ghost?" ”

Tang Yu was stunned for a moment, and then scolded directly: "Shut your dog's mouth!" Get over there and get to work! ”

The guy shrank his head timidly, his old face flushed, and he quickly continued to find clues honestly.

At this time, Wang Jianfei had already conducted a strict investigation and inquiry of the other three owners, and walked over with the transcript and the video of the scene of the inquiry.

Tang Yu asked, "What was the result?" ”

Wang Jianfei said: "The neighbor has a major suspicion, so our inquiry and investigation are very careful and strict, but in the end, there is no result, a neighbor on the left, there is a pair of old men and old ladies, the old man used to be a soldier, has always maintained the routine of the army, went to bed at six o'clock in the evening, no suspicion of committing a crime, and did not hear any movement and unusual sound last night." ”

"The neighbor on the right, lives a small start-up company owner, female, named Zhao Yue, twenty-six years old, the company's business volume has been more recently, she worked overtime in the company last night until two o'clock in the morning before coming back, and fell asleep after coming back, I asked her in detail what she saw and heard last night, but Zhao Yue said that she did not see anything unusual, and it was the same, she did not hear any movement."

Wang Jianfei continued: "The neighbor at the farthest end of the corridor lives a pair of young people who have just gotten married, but last night on Halloween, both of them went out to hi and didn't come back all night. ”

At this time, Xia Xixi just came over and said to us: "There are already results, that pair of young people, didn't come back all night last night, first went to the Shaguotou restaurant to eat, and then went to the bar to jump, around the early morning in the KTV ghost crying wolf howl, drunk directly in the KTV slept all night, I have contacted the manager of the KTV side to investigate the monitoring, the two of them are still sleeping in the KTV box, and they have not been out of the box door all night." ”

One ladder and four households, and the suspicion of the other three neighbors is all ruled out.

And the clue that the murderer said: "borrowing a scrub machine from a neighbor to divide the body" makes us put the direction of detection on the "neighbor", which is obviously wrong.

And, so far, we have not received any reports of the discovery of corpses, the discovery of homicides, etc.

Everyone was in a hurry, and Cai Wei and Chen Xingxing urged us to solve the case quickly! Be sure to find out the murderer as soon as possible, eliminate the influence, and don't affect Caiwei's creation!

But we are also very helpless, the whole serious crime team is very anxious, but there is no way.

The final direction can only be placed on the trace inspection of the doorknob.

"The killer tried to pry my door open outside, but in the end it didn't work." This clue Cai Wei was very confirmed!

That's the only clue that leaves us.

Tang Yu said: "The trace test results are estimated quickly, if they have not been pried, the nature of the case can only be defined as a prank by a friend!" ”

When Cai Wei heard Tang Yu say this, she rushed over frantically, her eyes widened as if she was crazy, her eyes were full of helplessness and pity, and she begged: "Comrade policeman, it's definitely not a prank!" It's definitely not a prank on my friend's part, I don't have that many friends at all...... Please, don't leave me alone, that's a murderer...... If you ignore me, I'm really scared, so scared......"

I hurriedly held Cai Wei's shoulders and told her solemnly: "Miss Cai Wei, don't worry, we will definitely not leave you alone, but we also have to deploy police forces based on evidence and clues, can you understand?" ”

"At least so far, the killer doesn't seem to have left any trace......"

"My computer records have been deleted! Isn't that a clue? The murderer must have entered my house, and maybe he was hiding at the foot of some wall when I slept at night...... Comrade policeman, I beg you, help me, please save me......"

As she spoke, Cai Wei cried, her shoulders trembled from crying, it was so pitiful, all of us had no choice but to coax her slowly.

In desperation, Tang Yu had no choice but to ask Chen Xingxing, and after avoiding it, he asked, "Miss Chen, please tell me the truth, how is your good friend Cai Wei's mental state?" ”

Chen Xingxing paused for a moment and asked Tang Yu what he meant by this.

Tang Yu shook his head: "I don't think Miss Cai Wei is mentally ill, we rely on evidence to handle the case, I hope you can understand and cooperate." ”

Chen Xingxing said: "Weiwei...... I'm usually more homely, basically working from home, drawing comics, and we occasionally go out for dinner at night, just like that, there is absolutely no abnormality in the mental state! Moreover, she has a good habit of living, never drinks, she definitely goes home before ten o'clock in the evening, and she never spends the night outside......"

After hearing Chen Xingxing say this, this question became even more foggy.

For a woman whose social relationships and interpersonal background are almost like a blank slate, yesterday happened to be Halloween, and we don't have any other inferences other than to define it as a prank.

At this time, the colleagues of the trace inspection team, the trace inspection results have come out!

"How's it going?!"

I, Wang Jianfei, Tang Yu, and Xia Xixi, were so excited that I subconsciously rushed over directly.

After all, the results of the trace inspection are now related to the direction of the whole next step of detection.

A colleague from the trace inspection team said: "After our trace inspection, the door lock does have traces of being picked, and the lock cylinder has been damaged, from the outside to the inside. ”

"You see, there really are people! Comrade police, hurry up to the police! Be sure to keep Vivi safe......"

Chen Xingxing was excited when he heard this information.

Tang Yu frowned, motioned to Chen Xingxing to calm down first, and asked the trace inspection team: "Have you extracted fingerprints, or any valuable information?" ”

Unfortunately, the trace inspection team shook their heads: "There are no fingerprints, and there are no traces left, we can only be sure that the door lock has been damaged, and the rest, there is nothing." ”

"Alas!"

Tang Yu sighed: "What can I do about this......

"According to the normal procedure, we can hand it over to our colleague in charge of civil cases, but this is not a homicide, and there is no evidence pointing to a homicide...... In fact, it is not enough to take over the standard of the serious crime team. ”

"How is it not a homicide! The person in the call record said that he wanted to split the body, and he had already killed someone......" Chen Xingxing emphasized excitedly.

"Ms. Chen, that's just a call record, a rumor, that can't be used as evidence......"

"But the door lock has been broken, how do you explain it!?" Chen Xingxing fought back.

At the same time, the trace inspection team was helpless and speechless.

At this time, under a thick fog, I thought of a solution......
