"President Pang, don't worry," Zhao Yu said to Pang Zhihui with a dignified face in the interrogation room, "Without solid evidence, we will never wronged you! So, I hope you can cooperate with us well, if you can help us find out the real culprit, can't we return your innocence?"

"Detective Zhao, I know that you have solved so many big and important cases, and you are very famous......" Pang Zhihui was about to cry, and hurriedly said to Zhao Yuzuo, "I really haven't killed anyone, don't worry, as long as I know, I will definitely say, I will definitely say!"

"Well, that's ......good," Zhao Yu nodded with satisfaction and said, "President Pang, I would like to focus on asking, what was the situation when the hanging coffin was excavated in 85?

"Hmm...... Hey......" Pang Zhihui scratched his head and recalled for a long time, and then replied seriously, "That's a lot, provincial and municipal cultural relics bureaus, museums, construction personnel, and some experts and scholars from other regions, media reporters, etc., can't there be two or three hundred people?"

"Oh......" Zhao Yu thought for a moment and asked again, "If I want to know the exact list of these people, can you help me find them?"

"It should ...... It shouldn't be possible, right?" Pang Zhihui said, "At that time, the management was not as strict as it is now, and there seemed to be no list or anything like that. Oh...... Our level is the lowest, if you want to know, I'm afraid you have to ask the provincial unit!

"However, as far as I know, the initiator of the year is no longer alive ......."

"It's okay, this is not the point!" Zhao Yu waved his hand and asked again, "I just want to know, can you still remember the personnel who participated in your county-level units?"

"Hmm...... I was in my 20s at the time...... Pang Zhihui replied, "I can barely remember a few from our unit, but it's hard to say from other units!"

"Okay!" Zhao Yu said, "Later, you can write down all the people you remember for me, and the more detailed the writing, the better!"

"Oh...... Okay!hmm......" Pang Zhihui was a good thinker, and immediately couldn't help asking, "Detective Zhao, how can I listen to you...... Is the murderer in that expedition?"

"That's right!" Zhao Yu nodded bluntly and said, "If the fresh pry marks on the hanging coffin are removed, the old traces of the 7 coffins are completely consistent, which means that the person who placed the No. 7 female corpse is likely to take advantage of that scientific expedition!"

"But Detective Zhao, everything else is easy to explain, but we are engaged in scientific research, and the corpse ...... How can it not be corrupted? If it was put in 85 years, will it still be vivid in 33 years?" Pang Zhihui still refused to believe it.

"You don't have to worry about this!" Zhao Yu said, "It's because the corpse didn't decompose that my previous judgment was shattered!, so you just need to help me recall if there were any suspicious characters in the scientific expedition team that excavated the hanging coffin!"

"Suspicious person...... What is this......" Pang Zhihui began to recall carefully, "At the excavation site back then, there was a lot of thunder and little rain, especially when people found that the seven hanging coffins were all empty, and many people dispersed on the spot......

"At that time...... "At that time...... he scratched his head vigorously, bitterly recalled, "we did some simple collection work, and then we closed the coffin board......

"yes...... I still have a vague impression that when the coffin was built, all the people from the provincial and municipal units left, and only a few of our county and unit staff were left, as well as a few construction personnel......

"If there is a problem, then it can only emerge from these people......"

"So, when the coffin was covered, you were at least present?" Zhao Yu asked.

"Yes, that's a good memory!" Pang Zhihui said, "I'll go down and help myself!"

"Hmm...... Merely...... The No. 7 hanging coffin doesn't seem to be the coffin I built, but when every coffin is closed, someone makes a record, and in front of so many people, it shouldn't be possible for someone to do anything, right?"

"If someone takes the opportunity to place the body in the No. 7 hanging coffin, they will definitely not act during the day......," Zhao Yu analyzed, "only at night! Moreover, only after the coffin was closed!

"Oops, oops!" Who knows, when Zhao Yu mentioned this link, Pang Zhihui suddenly straightened his neck like a cockfight, and said with wide eyes, "Officer Zhao, Officer Zhao...... I seem to ...... I seem to know who the suspect is!"

"Oh, who is it?" Zhao Yu was surprised, and the other police officers were also very excited.

"No...... It can't be Jiang Yong's kid who did it, right?" Pang Zhihui said this detail, and his head suddenly lowered again.

"Jiang Yong?" Zhao Yu asked, "Who is this person?"

"It's a relative of mine who doesn't pay five suits, and we are all descendants of the Pang family!" Pang Zhihui said, "When excavating the hanging coffin, there were several experienced construction personnel, and Jiang Yong was one of them."

"Because of his kinship, I have some impressions of him.

"Hmm...... Jiang Yong is one year or two years younger than me, after dropping out of high school, he has been working on a construction site, I don't know why, that excavation of hanging coffins, he also participated!

"The most important thing is ......," Pang Zhihui said, "because he has the strength and is young, he has always been the main member of the construction team, from building scaffolding, to taking the cable car to rappelling, to opening the coffin and covering the coffin!"

"I only remembered when you mentioned the scaffolding just now......," Pang Zhihui said, "At the beginning, because there was nothing in the seven hanging coffins, our scientific expedition task could only be completed ahead of schedule, and on the day the coffin was closed, it was not early......

"I don't remember that the scaffolding was not immediately dismantled on the spot, it seemed like it was a day or two...... The specific impression is already unclear, and I did not participate in the sweeping work after the coffin was covered!

"But...... Jiang Yong and his co-workers should have been staring at it until the end!"

"Jiang Yong......" Zhao Yu touched the name and asked, "President Pang, this person, do you still have contact now?"

"Yes, ......yes," Pang Zhihui said, "Now I work as a security guard in the Water Conservancy Bureau! I saw it at the wedding banquet a few days ago!"

Hearing this, Zhao Yu hurriedly made a gesture at the one-sided glass, Ran Tao suddenly understood, and immediately pulled Captain Xiong Wendong to arrest someone......

"President Pang, you just said that in addition to Pang Yong, he also has a worker," Zhao Yu asked again, "How many are there, and are there any other people you know?"

"I don't know each other, there are six or seven of them, they were all quite young at the time!" Pang Zhihui said, "It's okay, you bring Jiang Yong here and ask, he should know!"

"Oh...... "I hope worried, "I hope ...... Jiang Yong is quite an honest person, he doesn't usually like to talk much, so he shouldn't do anything to kill people......, right?"

"That'...... What is his current family situation?" Zhao Yu asked again.

"It's because I don't like to talk, I used to be very strong and good, but now I'm still an old bachelor! When I was young, I seemed to talk a few times, but none of them came to ...... It should be that the other party thinks he is too boring, right?"

"Oh...... I haven't been married......" Zhao Yu pondered for a while, feeling more and more that this Jiang Yong was even more suspicious......
