In order to prove that such a man appeared in Xiao Aiqin's life, Han Cheng decided to start with Xiao Aiqin's relics.
He first looked at the diary written by Xiao Aiqin after she went to college.
There are 56 entries in the diary.
Most people of that era, especially students, liked to record their thoughts in diaries, so every sentence in the diary might contain a secret.
Han Cheng carefully read every diary entry written by Xiao Aiqin.
He found that in the first 40 diaries, Xiao Aiqin mostly recorded some feelings after going to college and new things he encountered.
In the last 16 entries in the diary, Xiao Aiqin's mood seemed to have completely changed. Although her words were very cryptic, Han Cheng, who was knowledgeable as an Internet writer in his previous life, could still see Xiao Aiqin's young girl Huaichun's mentality.
For example, Xiao Aiqin once wrote in a diary, "I don't like mountains very much. I like vast fields, woods and rivers."
In fact, the original sentence is: "I don't like mountains very much. I like vast fields, woods and rivers. Let's go together!"
This is a courtship letter written by a well-known writer to his crush.
From Xiao Aiqin's later diary, Han Cheng could read that such a man lived in her heart and took root in her heart.
Who is this man hiding behind the scenes?
Why didn't he dare to come forward and provide clues after Xiao Aiqin's accident?
Could he be the last person Xiao Aiqin is looking for?
Could he be the murderer?
In order to learn more about some details of Xiao Aiqin’s life in college.
Han Cheng and Yu Shan found Qu Xiao, a classmate in the same dormitory as Xiao Aiqin.
Qu Xiao is the same Qu Xiao who was fined by the teacher for using high-power electrical appliances in the dormitory, and Xiao Aiqin was also fined.
Qu Xiao is now in her early fifties and is a fat, middle-aged woman.
"I have always felt guilty about Aiqin's murder. If I had not used high-power electrical appliances to cook and eat, Aiqin would not have been fined. If she had not been fined, she would not have left alone. If you go to school to relax, you won't be targeted by the murderer..."
After Han Cheng and Yu Shan explained their intention, Qu Xiao said reproachfully.
"What is Xiao Aiqin's usual personality like?" Yu Shan asked.
"She is a quiet and introverted person, a bit withdrawn, and very defensive about strangers! But she is still very talkative with familiar people!" Qu Xiao replied.
Qu Xiao's evaluation of Xiao Aiqin is similar to Han Cheng's judgment of Xiao Aiqin's character from the diary.
"What are her usual hobbies?" Han Cheng asked.
"She usually likes to read and listen to pop music. When she goes shopping, she usually goes to bookstores and video stores!"
"Does Xiao Aiqin have a boyfriend?"
Qu Xiao shook his head, "No, at least we haven't heard her say it, and we haven't seen her getting closer to any man!"
"Before Xiao Aiqin was killed, was there anything unusual? For example, did she often go out alone?"
Qu Xiao tried his best to recall and said: "Officer, after you said that, I remembered that during the period before Aiqin was murdered, she did often go out alone, and the number of times was quite frequent. Sometimes she even skipped school to go out. She would never skip class in the past!”
A usually well-behaved, introverted and quiet girl suddenly went out alone frequently and even skipped school.
Could it be that she was going to see that man?
How did Xiao Aiqin know that man?
She enjoys visiting bookstores and video stores.
Most likely we met in these two places.
Han Cheng thought about it in his heart.
Two days after questioning Qu Xiao, Han Cheng held a case meeting in the conference room of the backlog team to prepare to re-adjust the investigation direction of the NTU corpse case.
"According to Professor Hu Yada's psychological analysis of the murderer, he is inclined to believe that the murderer is a highly intellectual person, and I agree with his view, so I decided to suspend the investigation of the deli owner and chef!"
"After interpreting Xiao Aiqin's diary and asking Xiao Aiqin's classmate Qu Xiao, I feel that there is most likely a mysterious man in Xiao Aiqin's life!"
"The focus of our current investigation is to find this mysterious man!"
After Han Cheng finished speaking, everyone nodded in agreement.
"Han Group, this is amazing, you just said there is a mysterious man behind Xiao Aiqin! Today there was a viral post on the Internet saying that the real culprit in the NTU corpse dismemberment case was Xiao Aiqin's mysterious boyfriend!" Computer genius Shen Mao He said in surprise while looking at the tablet.
"Put that post on the big screen!" Han Cheng said immediately.
He was also puzzled. By chance, someone knew about the clues he had just discovered?
"Okay, Korean team!"
Shen Mao projected the content of the post titled "Major progress in NTU corpse dismemberment case, the real culprit is Xiao Aiqin's mysterious boyfriend!" onto the large LCD screen.
Everyone looked at the screen.
The general content of that post is this.
The author of the post, "Seven of Spades", first briefly reviewed the NTU body dismemberment case, and then changed the topic and expressed his guess about the real culprit.
"Seven of Spades" believes that Xiao Aiqin is not an innocent college student as said in the news. She has a boyfriend, and her boyfriend is a married man.
Xiao Aiqin, who was deeply in love, forced her boyfriend to divorce in order to stay together.
His boyfriend couldn't bear the harassment, so he became murderous.
"Seven of Spades" guessed that Xiao Aiqin's boyfriend was a surgeon. After killing Xiao Aiqin, he used a sharp scalpel to cut up Xiao Aiqin's body into slices...
The post’s analysis of the NTU corpse dismemberment case was so thorough that many people felt that the poster, “Seven of Spades,” was either an eyewitness or the murderer himself.
Someone commented directly under the post: "You are not the murderer, are you? You know so much!"
"Seven of Spades" replied to this comment: "Haha! Guess?"
"Shen Mao, can you find this Seven of Spades?" Han Cheng said with a frown.
Although I don’t know who this “Seven of Spades” is, is he the murderer? But he knew so much inside information, some details that the police had not even released to the public.
Even if he is not the murderer, he should be an insider.
Gotta get him out!
"Team Han, little CaSS, give me two minutes, and I will find the IP address of the Seven of Spades right away!" Shen Mao said confidently, snapping his fingers.
Shen Mao, a computer geek, had to be a policeman. If he had become a hacker, all the network elites in the world combined would be no match for him!
