of course not.
Just to investigate these clues and evidence, the police spent three or four days.
During this period, a large number of police forces were mobilized.
If it is another suspect and all the witnesses and physical evidence are available, the detection of the case is basically considered successful. Next, we only need to supplement and complete the evidence chain, and then hand it over to the prosecutor.
But the problem is that the suspect is Xu Mo.
Detective Xu Mo's identity and the police officer's impression of him are on the one hand.
The most important thing is that Xu Mo has a high IQ and a strong sense of anti-reconnaissance.
If Xu Mo really wanted to kill someone, would he have left so many clues and witnesses?
Liu Tao looked at Fang Mu and asked, "You have dealt with Xu Mo a lot. Based on your understanding of him, would he be so careless?"
Fang Mu frowned, thought for a while and said, "It stands to reason that with his IQ and anti-reconnaissance ability, it is impossible for him to make such a low-level mistake."
Liu Tao nodded.
"There is another possibility."
When Liu Tao heard this, he narrowed his eyes and said, "He deliberately left so many loopholes."
"After all, except for someone from the school who saw Xu Mo following Chen Xuefeng before, none of the remaining witnesses could see his face clearly, including the taxi driver and the security guard of the community."
Fang Mu nodded.
After so many days of hard work, the police have a lot of evidence.
But the problem was that they couldn't be sure whether it was Xu Mo who appeared that night.
First, all witnesses gave almost the same description of the boy they saw.
He is about 1.85 meters tall, with a slim build. He is wearing a black peaked cap and a black mask. His appearance cannot be seen clearly. He is wearing a black sweatshirt and carrying a black travel bag.
To be honest, if you were dressed like this at night, if you weren't familiar with Xu Mo, you wouldn't be able to recognize him at all.
Secondly, there is the issue of time.
When they investigated Song Jiajia, they found that on the 3rd, Xu Mo did not go to school, but took care of Song Jiajia in the hospital. Xu Mo did not leave until the door of the inpatient department was closed at night and the nurse on duty made her first round.
Hospital surveillance also proves this.
In other words, Xu Mo was in the hospital before ten o'clock in the evening on the 3rd.
But after school, self-study is at 9:55 pm.
According to eyewitnesses, Shen Jiayi left the school after class, and the time of departure was about ten past ten.
The surveillance at the school gate also proves this.
If it was Xu Mo who appeared at the school gate, he must rush to school from the hospital within fifteen minutes.
But the problem is that the hospital where Song Jiajia is located is half an hour's drive from Baiyin University, and that's without traffic jams.
So how did Xu Mo get to school in fifteen minutes after the nurse's ward rounds, avoiding the other party's sight, evading the guards and surveillance cameras?
The nurse on duty did not see Xu Mo in the ward during her second ward round at twelve o'clock in the evening.
The corridor surveillance did not capture Xu Mo leaving the ward or the hospital, so where did Xu Mo go?
Of course, we all know the result, Xu Mo appeared at the scene of the crime.
The question is, how did Xu Mo leave the hospital without leaving the ward?
The police launched a heated discussion on this issue.
Their first thought was that Xu Mo might have left through the window.
But the ward where Song Jiajia was located was on the sixth floor of the inpatient department.
The windows in the ward were still half-open, so it was difficult to even peek in, let alone get out of the window.
There are no signs of the windows being dismantled.
The possibility of Xu Mo leaving the hospital through the window is basically ruled out.
Secondly, they felt that the nurse on duty that night might have made a mistake during her first ward round.
But after many inquiries, the nurse on duty was sure that she was right.
She did see Xu Mo in the ward and talked to Xu Mo, asking why Xu Mo didn't go home.
Xu Mo said it was too late and would not go back. At that time, she thought it was a pity that Xu Mo was so kind to his girlfriend.
This shows that Xu Mo was indeed in the ward at that time.
After thinking about it, they thought of another possibility.
Xu Mo used some means to tamper with the hospital monitoring.
Others may not be able to do it, but Xu Mo can.
However, to do this, Xu Mo first had to enter the control room, and secondly, he had to remove the security guards on duty.
But the hospital's monitoring room is on the underground floor and cannot be found by ordinary people.
Even if it were found, it would be impossible to enter.
Although Xu Mo may have used his identity as a detective to enter, according to the security guard on duty that night, Xu Mo did not enter the monitoring room that night, nor did he appear near the monitoring room.
As for evacuating the security guards, it would be impossible to sneak into the control room using the time difference.
There are two security guards in the control room.
The most important point is that there are two monitoring points in the inpatient department, one on the underground floor and one in the dean's office.
Even if Xu Mo could enter the monitoring room on the basement floor to modify the monitoring, he would not be able to enter the dean's office.
When the discussion and analysis reaches this point, things reach an impasse.
Liu Tao scratched his head and said helplessly: "It seems that it was not Xu Mo who followed Chen Xuefeng and the two that night, but someone else. Otherwise, it doesn't make sense."
Hearing this, the others nodded.
Fang Mu said at this time: "There is another possibility."
"What?"
"The person who stayed in the inpatient ward that night was not Xu Mo himself, but someone else."
"other people?"
As soon as these words came out, everyone was stunned.
Liu Tao even asked directly: "You mean, Xu Mo found someone else to put on his own clothes and stay in the ward to take care of Song Jiajia on the night of the 3rd?"
Fang Mu nodded.
Liu Tao thought for a while and then asked: "If your hypothesis is true and someone is indeed pretending to be Xu Mo, how do you explain the conversation with the nurse on duty at that time?"
"This is easy to do, such as imitating Xu Mo's speech, or using a recording. Anyway, the nurse on duty didn't see his face." Fang Mu said.
Liu Tao thought for a while and felt that this was possible.
But there are still problems that cannot be explained.
"It can be explained by talking, but how can we explain the disappearance of the impostor?"
"According to what you said, Xu Mo hired someone to impersonate himself in order to kill people and leave evidence of alibi. In this case, the impersonator must have stayed in the ward all night, at least during several ward rounds by the nurse. You must be there during the period.”
"The nurse's ward rounding time is basically fixed. Knowing that twelve o'clock is the second ward rounding time, why is the impostor not there?"
"Most importantly, how did the imposter leave the ward?"
Fang Mu fell silent in response to Liu Tao's series of questions.
This was also what he couldn't figure out the most.
While the two captains were deep in thought, a police officer couldn't help but said: "Is there a possibility that the nurse on duty lied and Xu Mo was not in the ward that night."
