"Why is there such a speculation? The murderer's method of killing Hong Yi and Li Lanke is so perfect, and his actions are fast and accurate, if it is the same person, why just use the skull to play a prank and not attack her?" Feng Lao asked.

"I don't know. Ye Fan shook her head, and she couldn't figure out this question.

"Oh, I didn't think of this earlier, otherwise I would have been able to find a way to see if there was a bite on his wrist. Ye Fan snapped and slapped his forehead with remorse.

Then he recalled the two times he had seen Xie Qi before, and said excitedly: "Although I don't know if he is left-handed, I remember that when I met him in the library, his watch was worn on his left wrist. ”

"Right hand. Ye Fan blurted out, his dark eyes flashed with a bright light, the stars flashed in his eyes, and he stroked his palm and said: "Most people's watches are worn on the left wrist, because the right hand is easy to bump and bump in life, and the arm is also pressed, unless it is left-handed." ”

"Wearing a watch, on which wrist?" Feng Lao keenly grasped the point.

It's not like when you want to kill someone, you still wear a bracelet, right?

"Not only that, I found a star-shaped shell pearl in Hong Yi's throat, coupled with the thin thread of blood between his teeth, I suspect that Hong Yi bit the murderer's hand, Xie Qi is wearing long sleeves and a watch, and I can't see if his wrist is injured, but I noticed that when I saw him the first few times, he didn't have a bracelet on his hand. ”

"But this Xie Qi didn't appear on the list of the Y family's plum blossoms?" Feng Lao immediately pointed out her hesitation about this object of suspicion.

"But ......" After saying Xie Qi's doubts, Ye Fan hesitated again.

She once watched a news, a girl studying medicine, her boyfriend split her legs, and showed off in front of her every day with a new love, and finally the girl couldn't stand it anymore, and stabbed the boy more than 20 times with a knife, and the knife avoided the vital point, and finally the boy was greatly traumatized but was still judged to be a minor injury.

"The murderer is obviously very familiar with the structure of the human body, and the techniques are also very skilled, and he is quick and accurate, ordinary people, even if their psychological quality is good, it is difficult to have such a technique, but if it is a doctor, it is completely possible, especially if he is a professor of clinical medicine. ”

"Another point, Li Lanke was hit by one hundred and eight knives, Hong Yi had two hundred and fifty knives, the knives and knives can avoid the vital points, and the proportions are very good, to ensure that they can survive the abuse of the whole scene alive, and will not lose their breath halfway, I carefully examined the knife cuts on the two corpses, and I can confirm that none of the knives were cut after death. ”

......

"The whole school knew that he was in love with Lin Yanyan, and in the days when she left school, he was even more sad, but I deceived him today and found that his feelings for Lin Yanyan were not like the rumored deep love, but he pretended to be in love, so I suspect that he deliberately approached Lin Yanyan for some purpose. ”

"Bai Xingyue is a top student of pharmacy, and Xie Qi, as a professor of clinical medicine, holds two pharmacy books like treasures and does not allow others to touch them......

"Xie Qi is a professor at University A, and he also participated in the Christmas party last month, and he has seen the murder sketches of our college, and he can completely replicate the murder scene. ”

"Hmm. Ye Fan nodded, "I have asked the Chang team to find out the identity of Xie Qi. ”

"Do you suspect that this Xie Qi is the boyfriend in Bai Xingyue's mouth?" Feng Lao looked at the drawing board next to Ye Fan analyzing the case, and his wise eyes also fell into deep thought.

Ye Fan groaned and said the strangeness of seeing Xie Qi several times, and then said: "I found out, a security guard once said that there was a medical school department flower who rejected Hong Yi and slapped him, and also claimed to have a boyfriend, if there is no accident, this department flower should be Bai Xingyue, if Bai Xingyue has a boyfriend......"

"Suspicious object?" As soon as Feng Lao saw Ye Fan's expression, he saw what she was thinking.

The remaining six people on this list are four men and two women, from all over the country, and none of them are from Lucheng, and none of them are ...... The name of the person she suspected—Xie Qi.

Speaking of this, Ye Fan picked up the list of the Y family and said: "Among them, there are seven people with flower nationality, and there are twenty-five people from the entire Asian nationality, excluding Hong Yi, there are six people with flower nationality, I have already given the list to the permanent team to carefully check the situation and whereabouts of these six people, and there is no news for the time being." ”

"In both cases, the murderer fell from the roof of the building with a climbing rope and entered the bathroom to kill people, using the 'plum blossom' equipment of Y's family......"

"Yes, master. Ye Fan also understood this truth, pulled back from the speculation and conjecture of Lin Yanyan, continued to analyze the scenes of the two murders and the clues of the investigation, and finally made a partial criminal profile.

"Whether Lin Yanyan's skull case is related to the murder case will not be mentioned for the time being, and in the absence of more evidence to support it, I will jump out first and continue to analyze the clues of the murderer in the murder case. Feng Lao saw that Ye Fan had been pondering, and his brows were getting tighter and tighter, so he asked her not to continue to think hard, without the support of evidence, it was easy to fall into the misunderstanding of self-perception in inference and deep thinking.

And Xie Qi, he also has a lot of strange things, what is the matter with him and Lin Yanyan?

It is precisely based on this that it doesn't make sense, and because Lin Yanyan's identity can't be investigated, she didn't tell the regular team, but she analyzed the case with her master, except for those supernatural things, she said it herself.

Heh, with Lin Yanyan's ruthlessness, where did the murderer have the opportunity to kill Li Lanke and Hong Yi, there was no scum left for a long time.

Ye Fan frowned thoughtfully, it's still not right, in the eyes of ordinary people, no matter how flamboyant Lin Yanyan is, she is just a weak woman who has no power to restrain her, if the murderer has not done anything to her, it is impossible to know her ability, but if she has done it......

Lin Yanyan is a cultivator, no matter how good the murderer is and how good her physical fitness is, he can't move her.

Is it because Lin Yanyan is not the main culprit who killed Bai Xingyue? Or is it because ...... Can't kill her.

If the murderer wanted to take revenge on the person who killed Bai Xingyue back then, why did he just play a prank on Lin Yanyan, instead of killing her like he killed Hong Yi and Li Lanke?

Originally, she just had a thought, but after seeing the Five Elements Spirit Refining Evil Array in the Eastern District, she became more and more sure that Lin Yanyan must have been involved in Bai Xingyue's death back then.

Ming Jiu, who had been silently by her side, serving tea and water to her, saw her for a long time, and was pouring her a glass of honey water, ready to drink it when she finished speaking, when she saw her patting her forehead, the crisp and loud voice, which made him distressed, appeared beside her with a water cup, and rubbed her smooth forehead for her.

As a result, he forgot that Ye Fan was watching a video with Feng Lao.
