Chapter 82 Couple Butcher: Couple?

In the interrogation room, sanitation worker Zhang Guofeng sat nervously on a chair, his eyes glancing around, as if he had done something wrong.

Sun Guangtian frowned when he saw him.

He and Fang Rui looked at each other, and they both had the same idea: this man should not be the murderer. The psychological quality of a serial killer cannot be so bad!

"Where were you from six to eight o'clock in the evening of the 28th?" Sun Guangtian asked.

"I was resting at home that day."

"Are you sure?"

"Ah, no, I didn't have a day off that day, I was on duty. I went to the gate of Jiangzhou University to clean the sanitation."

"You'd better tell the truth." Sun Guangtian's tone was a little impatient.

Zhang Guofeng looked aggrieved: "I told the truth. I am an honest man, why would I lie? I haven't done anything wrong!"

"Your car arrived near the school at around six o'clock, but you didn't go to the school gate to clean until around eight o'clock. What did you do during this time?"

"I..." Zhang Guofeng hesitated for a long time and finally came up with a reason, "I went to the toilet. I had diarrhea that day and took it out in the woods."

"Where did you take it out? Take us there now."

"I... I forgot."

Sun Guangtian saw that his face was flushed, "Tell me the truth, did you go to gamble or to whore you."

Zhang Guofeng's voice rose a few centimeters: "What do you mean by whore you? Can it be called whore you if I go to see my old lover?"

"Seek my old lover?"

"The tigress in my family is very strict, so I can only see my old lover under the pretext of going out to sweep the land, otherwise she will beat me to death."

Zhang Guofeng shrank his neck, "I usually drive the garbage truck out early, and then park the car next to the grove. I then go through the woods and take a shortcut to my lover's house. I dare not drive to her house directly, for fear that others will see my car parked downstairs of her building and tell my wife. I went to her house that day, and she can testify for me."

"Who else has the key to the tricycle?" Sun Guangtian asked.

"I am the only one who has the key."

"Do you often have affairs like this?"

"What do you mean by having an affair? I just go to her for a massage. I go there about two or three times a month. Sometimes five or six times."

"Does anyone know about this habit of yours?"

"No one knows! Otherwise, my wife would beat me to death. I always go to see her secretly."

Captain Sun contacted Zhang Guofeng's affair partner, who confirmed that Zhang Guofeng was fooling around with her during that period.

The surveillance near her home also proved that Zhang Guofeng was jogging all the way to her home. So he didn't have time to dig a hole to bury the body.

His suspicion was temporarily cleared.

After the interrogation, it was already past eleven o'clock in the evening.

Song Haiyang and his team were suddenly a little annoyed when they saw that the suspect they had finally found was not the murderer. They checked the surveillance day and night, but they made an oolong.

Someone complained, "I haven't slept for several days. I'm exhausted, but I didn't find anything."

"That's right. We are human beings, not machines. We need to rest!"

Sun Guangtian's face turned pale. He said to everyone, "Everyone go back and rest."

Everyone packed up and went back.

Only Sun Guangtian and Fang Rui were left in the office. He leaned against the window and started smoking again.

Fang Rui saw his look and wanted to comfort him, but was interrupted by him: "Fang Rui, you don't want to stay and watch me laugh, do you?"

"How could that be possible. That's how investigating a case works. Often you may investigate for half a month and find nothing. It's also possible that you suddenly find a clue and catch the criminal."

Fang Rui felt that Sun Guangtian was under a lot of pressure, probably because the case had been under pressure for more than half a year and the murderer had not been found, so Captain Sun was anxious to catch the murderer.

"I don't need your comfort yet!" Sun Guangtian interrupted Fang Rui, "Do you think this clue is gone? No, I think there must be something wrong with the car. I suspect that person is using Zhang Guofeng to avoid surveillance, and he should know Zhang Guofeng. As long as we continue to investigate, we will definitely find clues!"

"..."

The next day, Sun Guangtian checked all the surveillance about Zhang Guofeng that day, including the surveillance near his home.

He found that after Zhang Guofeng left home, a man wearing a helmet followed him on an electric scooter. The man was young, wearing sportswear, and looked like a college student. When he arrived near the school, he took off his helmet, and the surveillance captured his face.

There are often college students driving electric cars around the school, so when Sun Guangtian first started to investigate, he did not find anything abnormal about this man.

This man is Zhang Guofeng's son, Zhang Ming, 31 years old, who works as an animal trainer in a nearby zoo.

He originally worked in a zoo in Linzhou, but a year ago, he suddenly resigned and returned to Jiangzhou. The zoo where he worked in Linzhou is also very close to the wasteland where the body was buried.

Sun Guangtian thinks this man should be the murderer.

However, he has not found any evidence that Zhang Ming committed the crime, so he did not invite him to the police station for interrogation, but instead sent an experienced criminal policeman to follow him to prevent him from committing crimes again.

Sun Guangtian sent people to the zoo in Linzhou to investigate and see if they could find any clues. He himself went to Zhang Guofeng's house while Zhang Ming was at work and searched his house.

He checked Zhang Ming's shoes one by one and found a light purple mark on the white sole of one of his sneakers. The shoes were washed very clean and no dirt could be seen, which highlighted the light purple mark.

This was most likely the color he got when he stepped on the purple fruit in the forest.

"Boss, Captain Sun has found another murderer," Xiao Zhang updated the latest intelligence, "He is Zhang Ming, the son of the sanitation worker. Captain Sun suspected that his son used his father to transport corpses, and then secretly drove the car to bury the bodies when his father went out to have an affair."

Fang Rui asked Song Haiyang about the situation again. Fang Rui felt that although Zhang Ming was suspicious, he had a low level of education. How could he design an experiment to collect EEG data? And how did he get the EEG equipment?

"It seems that Zhou Junwei should not be the murderer!" Xiao Zhang sighed, "Can our investigative ideas be wrong?"

Mu Mian said, "Maybe the person who designed the experiment and the person who conducted it are not the same person? We need assistants when we do experiments. It is difficult for one person to complete a complex experiment."

"Forensic Mu, since the murderer targeted couples, he should be alone. Otherwise, how could he be mentally twisted because of hatred for couples?"

Xiao Li also chimed in, "Yes, if he had a partner, he shouldn't be a psychopath."

"Could it be that we have fallen into a psychological blind spot? Xiao Zhang, do you remember that you once said that Zhou Junwei might be a homosexual. He and Zhang Ming left Linzhou and returned to Jiangzhou City almost at the same time. Could they be a couple?"

If a couple committed the crime, then everything could be explained.

"Boss, but Zhang Ming works in a zoo, and Zhou Junwei is a university teacher. How can these two people who have nothing in common be a couple? The gap between the rich and the poor is too big."

Fang Rui thought for a while and said, "They are about the same age. Could they be classmates in junior high school or high school?"

Fang Rui and Xiao Zhang went to Zhou Junwei's high school to investigate. Zhou Junwei was in the first and second year of high school at Jiangzhou No. 11 Middle School. Coincidentally, Zhang Ming was also in this high school, but they were in the same year but different classes. Fang Rui found Zhou Junwei's second-year class teacher, Mr. Chen.

Mr. Chen was a middle-aged man in his fifties. He looked very old-fashioned and serious. When he mentioned Zhou Junwei, a disgusted expression appeared on his face.

"I was deeply impressed by Zhou Junwei. He had good academic performance, but he had psychological problems and was a bit perverted. He often harassed the monitor of their class, Chen Yuanan, and even tried to molest him."
