Return to 1983 and be a detective

Zhang Chengan was still disdainful at first, but now he couldn't help but nod. It's just that knowing is one thing, and doing it sincerely is another thing. The specific kind of growth he can have depends on his future work. My own understanding.

After Xu Shan completed the autopsy, he walked around the scene again, checking the windows, desk, drawers, etc., and finally focused on the book clips on the desk.

There was a pair of these book clips in Mao Dazhuang's dormitory before, but this pair was green and that pair was black.

There are several books in the bookcase, the number is obviously not as many as Mao Dazhuang's, and they are basically novels. These books were all brought back from the library, with the exception of one, which is a book about flowers.

"Lan Qingping doesn't seem to grow flowers." Xu Shan turned around and asked Zhang Chengan.

"This...I never asked."

"She probably doesn't grow. A young and artistic young woman like her is considered industrious and doesn't distinguish between grains and grains. She probably doesn't have the habit of growing flowers..." Xu Shan said and picked up the book on flower farming. After flipping through it, a pine leaf bookmark fell off.

This pine leaf bookmark is very beautifully made. It is a leaf of a five-needle pine. It is pressed on a piece of cardboard and fixed with tape. On the edge of the pine leaf is a poem: "I will never let go of the green mountains."

This character is written extremely beautifully, with an iron hook and a silver hook. Without 20 years of skill, it would be impossible to write such a character.

And this calligraphy was obviously not written by Lan Qingping. Although Lan Qingping's calligraphy is beautiful, his skills are still lacking.

Who specifically sent a bookmark to Lan Qingping?Or this person gave this book to Lan Qingping.Although I don’t know what the special meaning of this book is, it is quite strange to give a book about growing flowers to a person who does not grow flowers.

Xu Shan took the book and checked it over and over again. He found a fingerprint on the cover of the book. He used the tape he brought to extract the fingerprint. Then he searched for it on other things, and finally found it on a desk lamp. A fingerprint was also extracted.

This fingerprint is printed on the lampshade of the desk lamp. It seems that the position of the lampshade is difficult to reach, and most people will not touch it specifically.

With a thought, Xu Shan pressed the button of the lamp and found that the lamp was broken.I checked the light bulb and found that the filament was intact. The faulty part was the wire of the lamp. There were signs of being pulled on the wire, and there was blood on a section of the wire.

It seems that the murder weapon was this wire.The murderer didn't seem to be very tall, which can be seen from the strangulation marks. The murderer was facing the deceased and strangled her with a wire.

If you want to strangle the victim to death without much resistance, you must be an acquaintance, or you must have drugged the food, but this also requires the deceased to trust the murderer enough to eat the food provided by the murderer. OK.

Xu Shan thought about it. Generally speaking, the first person to be discovered can easily be the murderer. Especially in this situation, since Lan Qingping's death time can be very accurately inferred, there are very few acquaintances who have the time to commit the crime. , so Xu Shan asked people to find Teng Juan, who was the first to discover the deceased, for questioning.

Teng Juan looked shocked, her eyes kept looking around, but deep in her eyes, there was a trace of unconcealable sadness.Xu Shan politely poured her a glass of water and said in a gentle tone: "Thank you for always tormenting you."

After Teng Juan took a sip of water, her mood stabilized.

"Comrade Teng Juan, don't be nervous. I called you here to go through a routine procedure. After all, you are the first person to discover the crime. You should know the situation of the crime scene best."

"Actually, I'm not sure. I met him accidentally when I was looking for someone."

"Is that so? Did Lan Qing ever have a boyfriend during her lifetime?" Xu Shan put the logical emphasis on the word "male".

Teng Juan answered unconsciously, but also put the logical emphasis on the word "male": "Her style has always been very decent. I have never heard of her having a boyfriend."

"This is a bit strange. If she didn't have a boyfriend, how could she be pregnant with a child?"

"She's pregnant? How is that possible?"

Teng Juan seemed surprised, and then a trace of anger appeared on her face, uncontrollable anger.

"There's no need to be so surprised... By the way, who do you think is the most likely father of this child?"

Teng Juan shook her head: "I don't know, I just think it's unlikely. She is also a clean girl and is not married yet. How could she be pregnant with a child?"

"Is it possible that it belongs to Dong Damao?"

"Him? You said it's Dong Damao's?" Although Teng Juan raised her voice, she didn't seem too surprised.

"I think it should be him. You know, Lan Qingping rejected Mao Dazhuang before and wrote a poem to him, which made Huanjun Mingzhu shed tears. Do you know what the last sentence is?"

"Don't you wish we had met before we were married? Are you saying that Lan Qingping is actually interested in Mao Dazhuang?" Teng Juan's voice turned cold.

There was also a ferocious look on his face.

Xu Shan did not ask any more questions, but took out a piece of paper and said, "Okay, I'm done asking. Sign under here and you can go."

Teng Juan also seemed anxious. When she heard that Xu Shan had asked her to leave, she immediately picked up a pen and signed. However, she used her left hand to write the words, which were consistent with the handwriting on the library's previous borrowing records. It's crooked and looks very ugly.

After she finished writing, she returned the pen to Xu Shan. Xu Shan paid special attention to her hands and found that her left hand and right hand had calluses left by holding the pen when writing, so it is very likely that this woman also uses her right hand to write. It is even possible that she is actually right-handed, but deliberately uses her left hand to write in front of others to cover up something.

In fact, writing with different hands can make ordinary people think that these are words written by different people. However, a person's writing habits often do not change due to the difference between the left and right hands. Words written by the same person with his left and right hands will be placed in the handwriting In the eyes of experts, the handwriting is actually consistent.

It's a pity that Xu Shan is not a handwriting expert, but he does know that in Shanghai at this time, there was a handwriting expert named Wu, who was also the No. 1 handwriting expert in the country. If it was really necessary, he could ask that expert for advice.

As soon as she left, Xu Shan took fingerprints from the cup she took. This was the purpose of giving her water.

Otherwise, according to the detailed principles of interrogation, she would not be given water before she spits.

The fingerprints on the glass cup were very easy to extract. Soon Xu Shan obtained the fingerprints on the cup and compared them with the fingerprints extracted from books and table lamps. After comparison, Xu Shan immediately came to a conclusion. , Teng Juan was the murderer of Lan Qingping.
