"In other words, this murderer does not enjoy the pleasure of the death of the deceased, he enjoys the blood."

Su Tian said slowly, she said very slowly, every bite was very clear, and it seemed that she wanted to say it while thinking.

"How can it be explained that it was a gang crime, not a copycat." Bai Qi asked.

"It's a murder weapon." Su Tian said lightly, "In the three cases, the murderer left the murder weapon at the scene. ”

"Three?" Su Tian's voice paused, and Liao Wei asked with some surprise, "In the second phase of the case, there is no cyanide in the deceased's home. ”

"It's apple seeds." Su Tian took out a photo of a forensic autopsy and put it in the center of the table, "There are at least three undigested apples in the stomach of the deceased, which were fed after death. ”

"Everyone knows that apple seeds have a certain amount of cyanide in them, and the apple seeds of three apples are enough to kill people."

"The cyanide that could not be found at the scene and the apples that were stuffed after death were linked, and it was a sufficient amount of apple seeds that caused the death."

"Since the apple is the murder weapon and it is in the stomach of the deceased, it is naturally at the scene." Su Qian pointed to the photo and explained.

Liao Wei suddenly nodded.

"Going back to what I just said, there are three reasons why I believe that the gang committed the crime, and the first one is the murder weapon."

"To be precise, the murder weapon that remained at the scene."

"If in the first two cases, the murderer left the murder weapon at the scene to hide people's eyes, then in the third case, if the murderer just imitated, why did he deliberately leave the murder weapon at the scene, and he didn't even wipe off the blood stains on the knife."

"The second is that the scene is too clean, and we explore the psychological causes of the imitation case, which are nothing more than three, one is to have a deep grudge with someone, the second is to have too many emotional fluctuations, and the third is to worship the imitated."

"But whatever the reason, it can only be regarded as a murder of passion."

"But the third crime scene was too clean to look like a novice or a murder of passion."

"The third, the so-called mark, at first we all thought that the mark of the murderer was the rose painted on the wall, and the corpse that was arranged in the shape of large letters."

"But in fact, the carrier is not important, what is important is that the black rose, that is to say, whether it is painted or folded, the focus is not on the form, but on the black rose itself."

"Even, if I'm not mistaken, the provincial bureau only released the details of the rose, and did not say the shape of the body."

"How did the killer find out?" Su Tian paused before continuing, "However, even if there is no this, I can prove that this is a gang crime." ”

As Su Tian's words ended, her fingers tapping on the table suddenly stopped.

It suddenly became clear that this person habitually knocked on the table when he was thinking.

A few people were a little flustered, and some didn't expect the legendary cold psychologist to have such a calculating side, which was quite novel and interesting.

Bai Qi obviously didn't expect it, he thought of the comments on this psychological expert in the data, and instantly felt a little disapproving, and sure enough, the rumors could not be believed.

reacted, and felt a little funny, and inexplicably felt that this person was a little cute.

Bai Qi coughed lightly, as if to hide something, then looked up at Su Tian and said, "If you leave the professor, can you draw a portrait of the murderer?" ”
