Su Tian didn't answer immediately, but looked up at him, pondered for a while, and then said, "I can't draw a specific one, according to the clues that are currently available, if the murderer is still two people, I'm afraid there is no way to draw it completely for the time being." ”

"It is obvious that the murderers in the two cases are veterans, have a certain sense of anti-reconnaissance, and their actions are provocative."

"The murderers in the first two cases all took the form of enjoyable killing."

"In the first case, the other party was strangled with stockings, which is a typical way of killing people who enjoy the long flow,"

"In the second case, the murderer stuffed the murder weapon, the apple, into the deceased's mouth after the deceased's death, which is also a kind of enjoyment-type killing."

"It shows that the murderer is happy to commit a crime or kill someone."

"Judging from the way the murderer placed the deceased, he had a certain perfectionist tendency."

"You can see, the two black roses, both of which were painted by the murderer on the wall directly above the deceased's head, happened to be aimed at the tip of the deceased's nose."

"And the hands and feet are placed in perfect symmetry."

"Judging from the current clues, the murderer in the first two cases, male, is between 1.75 and 1.78 meters tall, has a certain education, is likely to have graduated from high school, is depressed in real life, is likely to do manual work, is arrogant, incompatible with the people around him, wears a metal watch, likes to watch detectives or TV, has had the experience of being fired once within a year or half a year, has a high IQ, has a certain perfectionist tendency, and is a typical antisocial personality."

Su Tian said this, paused, and then continued, "There is only so much I can see about the first murderer so far, and there will be some differences. ”

Liao Wei and Wu Hao had cooperated with Su Tian before, so they naturally had nothing to say about her ability.

But the others were in contact with Su Tian for the first time.

This will all look at Su Tian with an incredulous face.

"It's... How can it be! Xie Chen's eyes widened and he looked at Su Tian, the first time he had seen the power of a criminal psychology expert.

"After graduating from high school, watching and being dismissed, how can you tell it." Li Chen frowned and asked, this person is somewhat similar to Bai Qi's temperament, both are concise and clear.

Although Bai Qi didn't speak, he was obviously waiting for Su Tian's explanation.

"It's the apple core, this person left the murder weapon at the scene in a grand manner, and even deliberately faked the death scene into a secret room, which shows that he has a full grasp of his IQ, in short, this person is arrogant and shows off his skills."

"Such a person chooses to use apple cores, a simple and non-technical way to extract cyanide, which shows that his knowledge of cyanide is limited, and there is no way to obtain cyanide."

"Of course, it's also possible that he didn't study chemistry."

"But don't forget that this murderer has a tendency to perfectionism, and killing people is no longer a simple task for him, but a work of art."

"Any murderer with perfectionist tendencies would not allow his work to be left with flaws, but in fact, when he chose apple seeds as the murder weapon, he already had regrets in the second case."

"So, if he knew more about cyanide, he wouldn't choose apple seeds."
