Chapter 1829 (1/2)

According to the footprints left at the scene, the police can judge the location of the suspect in and out of the sanatorium. However, these are the internal data of the police and outsiders should not know.

Therefore, since the patient named Liu Cheng can tell the exact location, it shows that he may have really seen the suspect that night.

Unfortunately, Liu Cheng was a mental patient. If he found that the suspect followed the female employee into the toilet, he only needed to shout loudly to save the female employee's life.

However, Liu Cheng is mentally abnormal and has serious communication barriers. He is silent and seldom speaks. Otherwise, he would not have been sent to a nursing home by his family since he was very young.

However, in any case, Liu Cheng was still an important witness who witnessed the case. The police immediately sent the best psychological experts to communicate with him, and finally obtained a relatively complete confession and a portrait of the suspect!

However, despite the portrait, the suspect was still like a stone in the sea. Although the police never gave up the investigation, they still didn't find the real murderer in the end.

Now, when Wang can finds that this case is the case in the Memoirs of murder, he immediately obtains the police data of that year and begins to compare.

The first is the shoe print of that year. The technicians confirmed that it was a pair of common cloth shoes of size 42. The height of the murderer should be about 1.72 meters.

The height of nongzhifa is 1.73 meters, just wearing size 42 shoes.

Subsequently, Wang can compares the wanted portrait of the suspect with Nong Zhifa. However, the comparison result is somewhat unexpected.

According to the comparison of experts, it is proved that the similarity between nongzhifa himself and the wanted portrait is only 61%, which can not meet the standard of agreement.

However, such a proportion can not completely rule out the suspicion of nongzhifa.

Because, after all, this is drawn through the dictation of witnesses, and it is normal to have a certain deviation.

However, now that we have Nong Zhifa's memoirs on murder, the situation is obviously different.

Zhao Yu thought that as long as he took the photos sent by Nongzhi and asked Liu Cheng, the answer would be clear.

Unfortunately, although Liu Cheng is still alive, his condition has already deteriorated seriously.

Now he lives in Chaohai Sheng'an psychological hospital. In addition to eating, drinking and Lasa every day, he goes to the park of the sanatorium and dazes at the flowers in the park for a whole day.

Sometimes, even when it rains on a cloudy day, he will go out with an umbrella. His behavior is quite different.

Previously, Wang can had sent someone to visit him with the photos of Nong Zhifa, but Liu Cheng didn't say a word, as if he had completely lost his communication ability.

According to the hospital nurse, Liu Cheng is not unable to speak, but can't communicate with people normally and falls into a self closed world.

Therefore, the police officers had to return in vain.

Without Liu Cheng's confession, it is impossible to determine whether the real murderer of the case is nongzhifa himself?

Therefore, Zhao Yu felt that it was necessary for him to work hard on Liu Cheng to see if he could provide new clues to the case?

So, he dressed up as a mental patient, lived in a mental hospital, and tried to approach Liu Cheng as a patient to explore his voice.

Speaking of, this kind of task is also very wonderful.

If you change to a prisoner, Zhao Yu has some means to let him speak, but in the face of mental patients, he doesn't know how to start?

Since entering the mental hospital, Zhao Yu has been trying to get close to Liu Cheng all the time, but as the data show, Liu Cheng seems to be just air and completely turns a blind eye to Zhao Yu.

Even if Zhao Yu took the initiative to pick on him, he didn't feel it and didn't respond.
