This point, if other forensic medicine is present.

It is estimated that they will subconsciously attribute the cause of the hyoid fracture to the victim, and the similar reason is attributed to sun Kehua.

But, although this second murderer's technique is very clever, but also can conceal most of the forensic medicine.

If you want to hide from him Zhang Xiaofan's brilliant eyes, this is obviously unrealistic!

But also because of this, it is more and more let Zhang Xiaofan feel concerned.

Who is the criminal suspect who strangled Wang Xiuli to death with rope? What is the relationship between him and sun Kehua?

What's more, if we simply look at the situation of strangling Wang Xiuli to death from this method, how can it be similar to that of strangling Li Changming.

However, because Wang Xiuli's body was five years ago, there was no injection of formalin on the body for body protection, and now it has become a white bone under the erosion of nature.

Zhang Xiaofan is not really an immortal. How can he judge whether the trace of Wang Xiuli's strangulation is really similar to that of Li Changming through a sentence of severely weathered bones?

Is it not sun Kehua who killed Li Changming, Li Changtian and Li wusheng in a series of murders, but someone else?!

Although at this time, there are still many mysteries to be solved.

However, Zhang Xiaofan has a kind of intuition in his heart.

There must be countless ties between the serial homicide case of Li's direct family and the 7.21 massacre five years ago.

At the same time, these two cases are not as simple as Zhang Xiaofan seems on the surface...

there must be a deeper conspiracy hidden in them!

"Zhang Xiaofan?"

In Zhang Xiaofan is wringing eyebrows, is thinking in the heart, but heard behind him suddenly came a weak female voice.

He followed the reputation, but saw Liu Shengyao did not know when he had stood behind him.

"Something?"

Zhang Xiaofan doubted and said.

"En..."

Liu Shengyao nodded. Just now he looked at Zhang Xiaofan, holding his chin and twisting his eyebrows.

Obviously, he was thinking about something.

Therefore, she did not dare to speak directly, for fear of interrupting a key thinking node of Zhang Xiaofan and affecting the follow-up case handling situation, it would be more than worth the loss.

Until Liu Shengyao saw Zhang Xiaofan's eyebrows spread out, she then pressed her voice and whispered to explore.

"What's the matter? There is no outsider to say it directly... "

looking at Liu Shengyao who has been waving his teeth and claws in front of him all the time, he even has such a weak and weak look. Zhang Xiaofan can't help shaking his hand and laughing.

"Well, what do you think are the causes of death of the other four victims except that Wang Xiuli was stunned with a blunt instrument and then strangled to death by rope?"

Zhang Xiaofan fumbled his chin and pondered in his heart.

"In addition to Wang Xiuli was strangled to death, among the remaining four victims, the No. 1 victim can see that there are multiple knife marks left on both sides of the ribs, and it is preliminarily judged that she was repeatedly stabbed to death by sharp weapons."

"The second victim, however, could see a sharp knife mark two inches in front of his cervical vertebrae..."
