Chapter 3180

This case was also not solved and was also a cold case. Because there are still many differences between it and the serial murder case, Ren He Weidong could not rashly merge this case with those serial murder cases, but he also took this case out as a key investigation object.

Ren He Weidong always had a feeling that this seemingly ordinary attempted robbery and rape case, the gangster is likely to be the same person as that serial killer.

He found the female high school student at that time. She is now in her thirties, a wife and a mother. She works in the Agricultural Machinery Bureau of Baozhou District and is an ordinary cadre. When Ren He Weidong just found her, she was not very cooperative and even had some resistance.

Su Su Xinghui can understand her thoughts. She now has a normal life and does not want to be disturbed by the things of that year. That thing is a nightmare for her. It is normal that she does not want to recall it again.

And it is normal for her to have resentment against the public security department. After so many years, the case has not been solved. All this caused her resistance.

Ren He Weidong did a lot of work for her and promised her that it was a secret inquiry and not public, so she reluctantly agreed.

She recalled the things of that year. Some details were not in the case files of that year. The most valuable thing is that she provided some physical characteristics of the gangster, and from some behaviors of the gangster, it can be determined that the gangster is a left-handed person, and there is a possibility that his right foot is disabled.

The reason why it is said that there is a possibility of disability is because the gangster was limping when he hijacked her into the woods, and it was more obvious when he escaped, but it could not be determined whether he was newly injured or originally disabled, so she did not say it at that time, and the public security personnel at that time did not ask too carefully, so these details were ignored.

This is also because the public security in Baozhou City was too poor at that time, and too many malignant cases occurred, so this case was attempted, and the parties did not suffer any substantial harm, so it was not the focus of solving the case. In that situation at that time, the police force was seriously insufficient, which is reasonable.

But now Ren He Weidong asked about these details, but he was like a treasure. These details made his investigation scope greatly reduced.

He immediately ordered to focus on retired soldiers aged 40 to 50, 1.6 to 1.65 meters tall, strong body, left-handed, and right foot possibly disabled.

Such clear clues made the special case team quickly lock the target. This person is a worker in the original municipal thermos factory, named Zhang Erniu. He is 48 years old this year, from the countryside, was a soldier, was injured in a training, has a slight disability in his right foot, retired in the late 1970s, and became a worker in the thermos factory.

He has a strong body, practiced martial arts, and received strict military training in the army. His military quality is very high, and his various characteristics meet the standards.

However, the thermos factory has now been restructured and established as Baozhou Daily Necessities Factory. According to the leaders of the Daily Necessities Factory, Zhang Erniu is usually silent, but his performance is very good, his technology is learned well, and he is usually willing to help others. Everyone praises him, not like a criminal.

Ren He Weidong still let the leaders of the Daily Necessities Factory call Zhang Erniu to the factory office to interrogate him.

When Zhang Erniu received the notice and came to the factory office, he obviously had no psychological preparation. When he saw several fully armed police officers sitting in the factory office, he was stunned for a moment, and a look of precaution appeared on his face, but this look of precaution disappeared after only one second.

However, this detail did not escape Ren He Weidong's eyes. Ren He Weidong knew it in his heart. He said to Zhang Erniu, "You are Zhang Erniu, right?"

Zhang Erniu said, "Yes, I am Zhang Erniu."

Ren He Weidong said, "Sit down."

Zhang Erniu sat down on a chair opposite Ren He Weidong, his face was not uneasy at all, very calm.

Ren He Weidong said, "Zhang Erniu, do you know what we are doing?"

Zhang Erniu said, "You should be police, right?"

Ren He Weidong said, "Then you should know what we are here for this time, right?"

Zhang Erniu shook his head and said, "I don't know."

Zhang Erniu's demeanor was very calm, but it was precisely this calmness that made people more suspicious. Usually, when being approached by public security personnel, regardless of whether they have committed a crime or not, they should not be so calm.

Ren He Weidong said, "Zhang Erniu, you should know in your heart what you have committed. I hope you can recognize the situation. You should know our policy: leniency for confession, severity for resistance!"

Zhang Erniu said, "But I haven't committed anything, what do you want me to say?"

Zhang Erniu's performance let Ren He Weidong know that this is a difficult opponent. Although he felt that the murderer should be Zhang Erniu, Zhang Erniu's psychological quality is too good, and he has committed crimes many times without leaving any clues that can prove his identity, which brought huge difficulty to the interrogation.

Even if he knows it is him, but there is no evidence, no confession, this case cannot be said to be solved. After the detention period, he must be released if he is not released.

Ren He Weidong said, "Zhang Erniu, in May 1987, what were you doing at that time?"

As soon as this date was mentioned, Zhang Erniu's expression changed a little. Ren He Weidong could see that he seemed to have a feeling of relief. This was what Ren He Weidong expected. He deliberately mentioned only this date, just to make Zhang Erniu have a fluke mentality.

Because this date is the date when the female high school student was blocked and attempted to be raped. Zhang Erniu estimated that he was thinking that if the police only grasped this case, the problem would not be too big. Even if it was finally determined that it was his work, it was only an attempted case and could not be sentenced too heavily.

No matter how good Zhang Erniu's psychological quality is, this fluke mentality is what everyone has. No matter what, he will have some slack.

Zhang Erniu frowned and said, "1987, I was a worker in the thermos factory. What can I do? Isn't it just going to work and getting off work every day."

Ren He Weidong said, "What were you doing on the night of May 13th?"

This day is exactly the date when the attempted robbery and rape case occurred, but Zhang Erniu shook his head without thinking, "It's such a long thing, it's been 15 years, who still remembers?"

Such an answer is not unexpected by Ren He Weidong, but it is also true. It has been more than ten years, who still remembers so clearly.

Ren He Weidong is not in a hurry. He asks questions unhurriedly, and then announces that he will take summons measures against Zhang Erniu and bring him back to the public security bureau for interrogation.

While interrogating, Ren He Weidong sent people to search Zhang Erniu's residence.

Zhang Erniu's residence is in the staff dormitory of the thermos factory. He lives alone. He had a short marriage 13 years ago. At that time, he married a widow, but the widow soon divorced because of different living habits with him.

In Zhang Erniu's residence, nothing of value was found. He lived alone and kept his residence very clean. No clues related to the case were found.

And the interrogation work also fell into a stalemate. Zhang Erniu denied any questions, or said he didn't remember. In short, from the interrogation of him, no valuable clues could be obtained.

Just then, Ren He Weidong learned that Zhang Erniu had another residence, that is, his hometown. His hometown is in a countryside in the western suburbs of Baozhou City. There are three brick-tile houses and a courtyard, and the layout is similar to other farmers' houses.

Zhang Erniu's parents passed away 12 years ago. He only has two sisters, both of whom are married. He is the only male in the family, so this property became Zhang Erniu's.

Generally speaking, Zhang Erniu has a residence in the city, and keeping this property in his hometown is useless. Generally, he will sell it. However, Zhang Erniu still kept this property and sometimes went back to live for a few days.
