It didn't take long for a police officer to buy Zhao Yu and others delicious Western food, steaks, hamburgers, pizza, etc., all of which were Zhao Yu's favorite hard dishes.

Zhao Yu was starved in the past two days, and he didn't care about the doctor's advice, so he immediately ate a hearty meal.

However, due to the urgency of the case, he was not idle even during meal time, and took the opportunity to watch the video of Wu Xiumin's interrogation of Han Kuan last night.

It turned out that during the interrogation, Wu Xiumin had asked Han Kuan the names of his classmates who had moved north with him to work. Han Kuan replied that there were a total of 5 people who went north with him, 4 men and 1 woman, all of whom were personally selected by Teacher Lang.

However, because it had been too long and they were not familiar with each other, Han Kuan could no longer remember the specific names of those people.

Except for that teacher Lang, he only remembered a girl named Li Yan. Not long after they arrived in the north, the SARS epidemic broke out in full force, and Li Yan was afraid that she would be infected in the north, so she went home early.

And after he actually started working, the rest of the people were also assigned to different places, so there wasn't much communication with each other, and he couldn't remember their names anymore.

Zhao Yu carefully observed Han Kuan's reaction, and sure enough, as Wu Xiumin said, except for being a little sluggish, he didn't see any signs of nervousness or excitement, and when he spoke, it seemed that he was completely telling a very ordinary thing.

But...... Just like when dealing with Han Kuan's murder of his wife, the more normal Han Kuan behaved, the more Zhao Yu felt that there was a ghost in his heart. Especially recalling Han Kuan's amazing performance in the toilet, Zhao Yu concluded that he could never be an innocent person who was detached from the outside world.

Even if he is not the murderer of the demon case, he must know something!

Just as Zhao Yu was watching the video, Miao Ying investigated new information. Through the visit, it was learned that one of the deceased in the demon case, the teacher of the Guang'an School for the Deaf and Dumb, did have bad rumors of bullying students, not only bullying students, but even a scandal of assaulting female students......

In addition, the shop owner in Yingping was also rumored to force female employees to strip and drink N before his death!

Zhao Yu remembered that about this shop owner, Captain Jin's yellow notebook also mentioned it. However, because the persecuted female employee denied it, the result was not found in the end.

Now it seems that the rumors may be true, either the boss gave the female employee hush money before, or the female employee is afraid that the scandal will not be good for her and dare not admit it......

It's so similar!

After getting such news, Zhao Yu and Cui Lizhu felt more and more that there were striking similarities between the demon case and the headless female corpse case. The deceased in these demon cases may have oppressed and bullied others during their lifetimes, and the purpose of the murderers in the demon cases is to use such extreme means to punish these people's crimes......

So...... Is Han Kuan an a victim of oppression or a terrible murderer?

Gee......

Although Han Kuan's suspicion is very great, Zhao Yu still feels that Han Kuan and Li Fei are two completely different people, if Han Kuan is really the murderer of the demon case, he should not behave so normally......

The special investigation team did not slack off, and the Yaoming Police Station naturally went all out, and in just one morning, they found out the information of several classmates who went north with Han Kuan that year.

The news confirmed that what Han Kuan said was true. Those who went north with him were indeed 4 men and 1 woman, a total of 5 people. And the girl named Li Yan did return to her hometown because of the outbreak of the epidemic.

Therefore, the focus of the police's investigation quickly shifted to the remaining 3 boys. It is understood that these three boys, like Han Kuan, only worked in the north for half a year, earned a small amount of money with that teacher Lang, and then returned to their hometowns to work.

At present, the Yaoming police have contacted the local police station and are investigating the location of these three people to see if there have been cases similar to the demon case there. If there is, the real culprit of the demon case can naturally surface!

As the saying goes, once you have a goal, the investigation can be carried out continuously.

Since that Li Yan had already ruled out suspicion, Zhao Yu immediately asked Cui Lizhu to call this Li Yan and wanted to learn more about the situation back then.

But who knows, after the phone was connected, Li Yan refused to cooperate, not saying that Cui Lizhu was committing telecom fraud, and then hung up the phone.

In desperation, Zhao Yu and others had no choice but to contact the local police through the official again, and the local police informed Li Yan's leader that they came back in a big circle, and Li Yan believed it.

Of course, the name of the Criminal Department is not covered, Li Yan not only believed it, but was also so frightened that she couldn't even speak.

However, Li Yan has a good memory, and immediately said all the names of other people accurately, including Han Kuan.

Li Yan said that the reason why she followed Teacher Lang to the north to earn extra money was not only because she could get paid, but also because she was from Nanjiang and not far from moving north.

At that time, she was mainly responsible for clerical work such as shipping and bookkeeping, and she was not tired of working and earned a lot of money.

However, no amount of money is more important than life. Therefore, when the SARS epidemic broke out suddenly, she still chose to resign and go home. Although Mr. Lang was a little unhappy, he couldn't help it. She only went to Nanjiang for less than half a month before returning to her hometown in Nanjiang.

"That's a good ......" At Zhao Yu's suggestion, Cui Lizhu asked on the phone again, "You can tell me in detail about the situation of the other classmates!"

"The other few, good ......" Li Yan recalled a little and said, "Liu Haoran will ship with me, Sang Wenliang will transport the pipe, Li Qiang and Han Kuan are technicians, responsible for equipment installation and maintenance, ......"

Oh?

Hearing this, Zhao Yu's eyes lit up, and he hurriedly wrote down the name of this Li Qiang from the paper. Among the 3 people, only Li Qiang and Han Kuan are doing the same kind of work, so this Li Qiang is naturally the most suspicious!

"Oh...... That's right!" Li Yan thought for a while and said, "Among these boys, I am the only one who Han Kuan is not familiar with, and the other three male classmates are all in the same class as me! Teacher Lang is the head teacher of our class, and Han Kuan is in class 11, Teacher Lang has only brought lessons to their class, I don't understand, why did Teacher Lang come to him, I think...... Maybe he's technical, okay......"

Oh?

Not a class, nor their homeroom teacher......

Just as Zhao Yu noticed something, Wang Can gently pulled him and showed him a piece of information. But seeing that the information shows that Li Qiang is from Zhao County, and this Zhao County happens to be under the jurisdiction of Yingping.

In other words, Li Qiang's hometown is located within the scope of the northward migration. The northward migration is the most sensitive area for the demon case, and if Li Qiang is the murderer, then once there are similar cases in the future, it will inevitably attract the attention of the police. Therefore, this Li Qiang is not very suspicious.

That......

If Li Qiang is not suspicious, is it ......

At this time, Li Yan was still talking to herself on the phone, and Zhao Yu spread all the information he had obtained so far on his hospital bed.

Oh......

Suddenly, he found another problem: among the five classmates, only Han Kuan was from the Golden City, and he was far away from moving north. The other 4 people all live in the area near the north!

It's not the same class, and my hometown is not near the north......

In such a comparison, Han Kuan's move to the north to work undoubtedly seems very unreasonable...... Moreover, Lang Xiangyang is not Han Kuan's teacher at all...... That......

Suddenly, Zhao Yu finally thought of a key question, and goosebumps broke out on his body!

Lang Xiangyang, why did you choose Han Kuan!?

Don't...... It's not the students who really have the problem, it's the teachers!?
