When Liu Dayu showed the lighter to Yin Xiuxiu, the wife of Jin Yougui's neighbor Cui Da'an, she said that Yu Changsong's lighter was about the same size and shape as the lighter in Liu Dayu's hand, because he had borrowed Yu Changsong's lighter to light candles more than once. But Yin Xiuxiu can't be sure that the lighter in the photo is Yu Changsong's lighter, in Yin Xiuxiu's impression, Yu Changsong's lighter has a round trademark, but the lighter in Liu Dayu's hand does not have this round trademark. The reason why Gan Dejun and his wife didn't recognize the real thing is probably because of this!

The most important thing is that the time when Yu Changsong left the Jin family and the time when the deceased was killed also coincided. Yin Xiuxiu also remembered one thing: when Teacher Zhao was sick and hospitalized, Yin Xiuxiu and Jin Xianju went to the hospital to visit Teacher Zhao - the children of both of them had read in Teacher Zhao's hands - or asked Teacher Zhao for advice on learning problems, and the relationship has always been very good. On the way to the hospital, Jin Xianju mentioned the divorce. According to Gan Dejun and his wife, it was at this time that the deceased had an accident.

Strangely, when Liu Dayu showed the simulated portraits of the deceased to the interviewees, they all said that they didn't look much like Yu Changsong. Although both of them had long faces, the deceased's chin was more pointed, while Yu Changsong's chin was wider. The cheekbones of the deceased were relatively high, while the cheekbones of Yu Changsong were relatively flat.

Not only that, but the people in the Cui family compound, including the people near the Chen family compound, don't think the people on the simulated portrait are familiar, what's going on? Ouyang Ping was puzzled, Mr. and Mrs. Zhao and Mr. and Mrs. Gan Dejun both said that they had seen this person, while the others in Xie Juren Lane said that they had not seen this person, could it be that the deceased only appeared in such a specific environment as the Chen family compound before he was killed, if this is the case, Mr. and Mrs. Zhao and Mr. and Mrs. Gan Dejun should be able to search for this person from their memory. There are also two families in the Chen family compound, and if the deceased has ever appeared in the Chen family compound, the other two families should also have some impressions.

Thinking of this, Ouyang Ping made a memo in his notebook: On the morning of August 4th, I asked the third man and Zhang Bingkun to understand the situation.

Everyone fell asleep with all kinds of doubts.

At half past six o'clock the next morning, everyone gathered in the criminal investigation team, and after discussion, Ouyang Ping, Chen Jie, Yan Jianhua and Han Lingling stayed in the criminal investigation team to wait for Zhao Qianqian's arrival; Liu Dayu, Li Wenhuazuo, Xiangdong and Liu Wenbin went to the scene of the crime to meet Gan Dejun, and then contacted the Jin family.

Let's first talk about the situation on Ouyang Ping's side:

At 7:05, a woman jumped off her bicycle at the gate of the Municipal Public Security Bureau, he was Zhao Qianqian, and a red leather bag was hanging on the head of the bicycle. Zhao Qianqian wore a knitted short-sleeved flesh-colored T-shirt on her upper body, a pair of purple wide-hip trousers on her lower body, and a pair of blue semi-high-heeled leather shoes on her feet.

The doorman walked out of the communication room and said through the small door: "Comrade, do you have something?" ”

"Comrade, I'm looking for Captain Ouyang of the criminal investigation team, and he made an appointment with me."

"Please come with me." The master janitor opened the small iron door.

The doorman walked to a three-story brick and wood structure in front of the ancient building: "Comrade, Captain Ouyang's office is on the second floor. ”

After Zhao Qianqian thanked the doorman, she parked the bicycle on the side of the road, locked it, pulled out the key, and went straight up the stairs.

Ouyang Ping had already seen Zhao Qianqian, and he was standing at the door of the office waiting for her?

Zhao Qianqian sat on the sofa on the right side of the desk, Ouyang Ping sat on the sofa opposite her, Han Lingling sat on the desk, there was a conversation record book on the desk, a pen was pressed on the record book, and Chen Jie and Yan Jianhua sat on the left and right of Han Lingling.

Zhao Qianqian put her knees together, put her two hands together on her right knee - her left hand on her right hand, leaning sideways, sitting on the sofa, with a ladylike demeanor.

When Zhao Qianqian sat down, Ouyang Ping noticed a detail: Zhao Qianqian had a yellow spot on the index and middle fingers of her right hand, which should be caused by long-term smoking.

From the moment she sat down to the beginning of the conversation, Zhao Qianqian's eyes only stayed on Han Lingling's face—or body, so to speak, she and Ouyang Ping sat opposite each other, but there was no eye contact with Ouyang Ping. The three men in the office were like non-existent objects.

Ouyang Ping also noticed: Zhao Qianqian's teeth are very white, and it is impossible for long-term smokers to have such white teeth.

"Captain Ouyang, you can ask whatever you want!" Zhao Qianqian said while looking at her watch, "I go to work at eight o'clock, there is only one hour, I work in the reading room of the city library, as long as the library opens, I can't rest." Zhao Qianqian spoke unhurriedly and spoke softly.

"Since the well in the Chen family's compound was sealed, have you noticed anyone wandering around the pile of broken bricks and tiles? Or what do you hear in the night? ”

"No, Captain Ouyang, I often live in the dormitory of the unit - I rarely live at home, my parents have not been settled because of my personal problems, and their faces are gloomy all day long, after I read it, I feel very uncomfortable, so I don't often live at home."

"Please look at this mock-up portrait - do you have any impression of this person?"

Yan Jianhua stood up and put the simulated portrait on the coffee table in front of Zhao Qianqian.

Zhao Qianqian leaned forward and looked carefully. But she kept a certain distance from the coffee table, and her hands were tightly clasped together.

"How?"

Zhao Qianqian raised her head, her eyes swept over Ouyang Ping's face, and then shook her head - this was the first time Zhao Qianqian looked at Ouyang Ping's face.

"Your parents and the couple next door, Gan Dejun, have seen this person."

"Who is this person?"

"They said in unison that their eyebrows were familiar, but they couldn't remember who it was for a while."

"I usually go to work and don't spend much time at home. This person's hair is very short, a bit like Jin Xianju's man Yu Changsong, but his face is not very similar. If the deceased did look like this, then it was unlikely that this person was Yu Changsong. Zhao Qianqian thought slightly. Her implication was: Can you be sure that this simulated portrait is what the deceased looked like when he was alive?

Zhao Qianqian's doubts are not unreasonable, to be honest, Ouyang Ping is also a little worried that there is a gap between the simulated portrait and the real person - the gap exists objectively. This simulated portrait was drawn by a computer, and this new technology has just been applied to criminal investigation work, and Ouyang Ping does not know much about this new technology.

Regarding the reason why Zhao Qianqian's boss is unmarried, Ouyang Ping wants to know the answer, but this is a very sensitive question that has nothing to do with the case, so where to start is a headache for Ouyang Ping.

"Yesterday, we talked with your parents for a long time, and although Mr. Zhao's health is not very good, his spirit is very strong."

"If it weren't for the fact that I wasn't settled in my marriage, my parents would be in a better spirit."

Zhao Qianqian herself mentioned the issue of marriage - and mentioned it twice, which is exactly what Ouyang Ping wants, so take advantage of this topic to jump forward!
