veneno Gu - Capítulo 41
Mr. Yang was taken to the Criminal Investigation Brigade.
Qu Baoyuan was among the 14 suspects. Detective Li was the first one he approached. When Qu Baoyuan arrived at the Criminal Investigation Brigade, the other 13 suspects hadn't shown up yet. He waited until the next morning before all 13 of them arrived. Qu Baoyuan sat in the Criminal Investigation Brigade all night.
The next day, Xiao Li was shocked to see Qu Baoyuan's face so swollen, it looked like an inverted triangle. He wondered if someone had beaten him up.
The criminal investigation team was poor and lacked the kind of two rooms and equipment seen in TV dramas, where witnesses could see the suspects and the suspects couldn't see the witnesses. They had to go to the lobby of the municipal public security bureau to identify the suspects. In order to protect the witnesses, they had to ask Boss Yang and a group of plainclothes police officers to sit together and have the suspects line up for identification.
Mr. Yang recognized a man surnamed Meng.
The police officers present tried their best to control their joy.
After identification by witnesses Zhao Yajuan and Tang Baoming from the May 31 burglary case, as well as Zhao Yajuan's neighbor and witness Yao Yulan from the June 14 burglary case, they all said that Meng did not resemble the perpetrator.
Further investigation revealed that this man surnamed Meng had just returned from out of town a few days prior, and was not even in the city when the four cases occurred. He also had no access to the victims' old cell phones.
I thought the case was finally solved, but it turned out to be another disappointment.
It was now July 23, four days after the Saturday of his death.
Wang Liguo recalled that day and told me that he just wanted to forget Saturday, July 19th. The only way to do this was to work like crazy, working until he couldn't sleep anymore, and then collapsing. In this way, he finally worked until the night of July 23rd, and still no one reported the incident. He concluded that this Saturday was probably truly peaceful.
He later said that no crimes happened that Saturday, and I was so excited I couldn't sleep. This was our first victory; we were on the right track. We were close to him, even touching him, which is why he didn't dare to commit a crime, or couldn't. This tells us that he is among those 260 people, among those 14. This means that no more young women will be murdered by him in this city.
This was later confirmed. After being arrested, the murderer confessed that he had chosen two more rooftop locations for the crime, not in the Gujing District, but he no longer had the opportunity to commit them and had to wait.
Wang Liguo said that he was so excited that he couldn't sleep that night, and kept thinking, since the murderer was among these 14 people, why didn't Boss Yang recognize him?
We selected these 14 individuals based on the suspect's physical characteristics. They are all around forty years old, roughly the same height and build, and their appearances are quite similar. Mr. Yang, on the other hand, was someone we knew from his own shop; his physical characteristics were unique, making him easy to identify. Now, however, Mr. Yang is facing 14 people who look almost identical. The one and only person he knew from his shop is gone. Undoubtedly, he will be under immense psychological pressure. He must choose one from so many similar people, something he never expected, which cannot help but cause him panic.
He originally intended to identify one person, but instead he's identifying 14 similar-looking people. How could he not be nervous? No wonder he made a mistake.
What do we do now? We must weed him out from these 14 people as soon as possible. How do we do that?
As dawn approached, he couldn't resist calling the bureau chief to request permission to conduct polygraph tests on the 14 individuals who matched the characteristics of criminal suspects.
The director said it's perfectly fine! I'll find you some psychological testing technicians right away, and we'll start tomorrow morning. But you must get the test subjects' consent beforehand; you can't just do whatever you want.
The testing experts worked with Wang Liguo to develop a lie detector test for 14 people.
The 10th person tested had no abnormal reaction. That makes sense, shouldn't only one person be able to have an abnormal reaction?
The 12th person tested, Qu Baoyuan, responded to all the test questions related to the four crime scenes.
Wang Liguo suppressed his excitement and asked the testing experts what they thought of Qu Baoyuan's reaction.
The testing expert said, "You know, psychological tests can only give a 100% negative result, but not a 100% positive one. I asked Qu Baoyuan carefully; he has tuberculosis and takes medication daily. I don't know what effect his medication might have on the test. Since I don't know what the effect might be, I can't say for sure that it has no effect. Therefore, I cannot evaluate the current test results."
Wang Liguo felt a chill in his heart again.
He thought for a while and said, "What you said makes a lot of sense! How about this: we'll let him stop taking his medication for three days, make sure he eats and sleeps well, and let him be full of energy before taking the test again."
The experts said that of course there would be no problem.
When asked what he wanted to eat, Qu Baoyuan tilted his head and said, "I want braised pork. Can you buy it for me?" Unexpectedly, braised pork was actually placed in front of him. He looked at the braised pork in the lunchbox for a while, then finally looked up and said, "You're a true friend! You're a true friend! Thank you, thank you!"
Three days later, the testing resumed in a quiet room, with only the testing expert and his assistant standing in front of the psychological testing equipment.
The testing expert told Qu Baoyuan again, "Today we are conducting a psychological test on you, specifically testing your true psychological reactions. For the questions we ask, you can answer 'yes' or 'I know,' or you can answer 'no' or 'I don't know,' depending on your own situation. If you don't want to answer, you can remain silent. How you choose to answer is your right."
Qu Baoyuan nodded dismissively.
The tester's wires were connected to his body.
The testing expert asked questions calmly, and Qu Baoyuan answered each question slowly, seemingly somewhat slow to react.
