Xu Dayuan didn't pick up, glanced at the time on his phone, the time had jumped to 23:27, and at this time he also felt that Wang Hongzhan was powerful, and raised his hand towards Wang Hongzhan.

"Yu Fei poured a glass of water for Wang Hongzhan, I'll make a call, there should be news from the city bureau."

With the sound of the door closing and opening, Xu Dayuan walked in quickly, grabbed the mineral water in front of Zhou Ning, and opened it for a while, Xiaoqu subconsciously moved a distance of one meter to the side.

"This kid is a crazy person, I talk to him specially, I feel that the tail bone is cool, the more I say it, the more awkward I feel, I always feel that he controls the rhythm, Xiaoqu checks, in addition to flights and trains, such as driving or long-distance buses, can you find out the information of last August?"

Koji spreads out her hands.

"Director Zhou asked me to check it just now, high-speed records, only kept for a month, if it was a eucalyptus at the time of our investigation, we might be able to find the information, but now we can't find it."

Speaking of which, Xiaoqu peeked at Zhou Ning and then at Xu Dayuan.

"It turns out that Xu Ju and Director Zhou are suspicious of Wang Hongzhan?"

Xu Dayuan snorted twice and sat beside Zhou Ning.

"This man has an extraordinary brain."

Xiaoqu leaned over.

"Director Zhou said just now that he didn't say a word about He Dongmei, but all the descriptions and the possibility of getting the password key fell on He Dongmei, plus the child was not his, so all the evidence was directed to the man related to He Dongmei.

But I don't understand a little, I just wanted to ask Director Zhou, looking at his eyes, I didn't dare to ask, you said that if according to what Wang Hongzhan said, the person who had an affair with He Dongmei was a murderer, why did he kill the child? Isn't this kid his? ”

Xu Dayuan glanced at the conversation room and rubbed his chin.

"Don't interrupt, I won't come out if I understand, I just interrogated Wang Hongwen, I think when he heard that the child was not Wang Hongzhan, he was very obviously stunned, okay Zhou Xiaozhou hurriedly called and asked Sister Cui there, is this report coming out?"

Zhou Ning took out his mobile phone, and before he could make a call, the mobile phone rang, Cui Lili's name flashed on it, and Zhou Ning connected in seconds.

"Big sister."

"The report is out, it has been sent to your mailbox, the male DNA sample you sent for testing is consistent with the DNA remaining in the gloves, and Wang Jiahan belongs to the genetic father-son relationship, and the last Wang Jiahan nail collection was only found in He Dongmei's bloodstains in the first extraction.

I didn't give up on changing the collection method, this time I was lucky, I found Wang Hongwen's DNA in it, and out of twenty samples, only one was collected, I think I still have to call you to talk about it. ”

"Okay, I'll take a closer look, you can rest quickly, and we'll talk about it tomorrow."

Sister Cui probably didn't have the strength to scold, hung up the phone, Zhou Ning asked Xiaoqu to log in to the mailbox, and took a look at the report, the first conclusion showed that Wang Hongwen's DNA was consistent with the male DNA residue in the glove.

Dirt, metal chips, petroleum jelly lubricants, and some basic copper carbonate were detected on the outside of the gloves, which were compared to the rust on the safe combination lock, and as for the petroleum jelly lubricant, it was consistent with the residue on the dagger gauntlet.

In the latter part, Sister Cui marked that if Wang Hongwen had been in Wang's house, or that Wang Hongwen had contact with the corpse after Wang Jiahan's death, this residue was possible, but now it is necessary to verify with Bai Forensic Doctor, after Wang Jiahan's death, whether anyone has seen the corpse.

Xu Dayuan also frowned, looking at these two reports.

"I'm so damned, this report can prove that Wang Hongwen is the murderer of He Dongmei and Wang Jiahan, right?"

Zhou Ning nodded.

"Coupled with surveillance, it can indeed be determined that Wang Hongwen has a major suspicion, but I think it depends on whether the gold bars can be found, or the evidence of selling the stolen goods, after all, this is the purpose of the murderer's murder, if Wang Hongwen did not sell the stolen goods, then the problem here is interesting."

......

Da Zhao glanced at the time, and it was already 21:17 at this time.

Several leaders of the Sixth Primary School in Hai'an City walked over quickly, and after a few polite words with a few local scouts, they opened the office where Wang Hongwen was.

Yang Xuetong took Sun Gaotie to Wang Hongwen's house, and of course there were local scouts, Zhu Xingxing followed behind Da Zhao, and seeing that the office and others were all lit up, Zhu Xingxing asked.

"If you are in trouble, you can come out and say, which table and cabinet belong to Wang Hongwen, and where are the other keys opened? Who knows, please put on gloves and help us open it. ”

The head of the English teaching and research group just introduced hurriedly stepped forward and took Zhu Xingxing's gloves, his hands were trembling at the moment, so many policemen, and two people dressed like this, knew that the matter was not small at a glance, but what was the specific matter, the police didn't say a word, the more it was so that it made people nervous.

"Wait a minute, I'll try!"

The man pulled his hair and rubbed for a long time before putting on his gloves, and Zhu Xingxing kindly reminded:

"Teacher, don't touch yourself, especially your hair, when you wear gloves, or your dander will remain."

The man nodded, walked towards a table in the window, and pointed:

"This table is Wang Hongwen's, do you want to open the drawer?"

Da Zhao waved his hand and pointed to the row of cloakrooms against the wall behind him.

"Is there Wang Hongwen's cabinet in here?"

The teacher fiddled with the key for a long time, and dropped it on the ground once in the middle, and finally opened the cloakroom, Da Zhao stepped forward, Zhu Xingxing had already asked everyone to withdraw, signaled the investigator to talk to the director of the teaching and research department, and then returned to Da Zhao's side.

Da Zhao held the purple lamp, looked up and down carefully, the cabinet was not big, the top was the place where the clothes were hung, the two drawers in the middle, and the two layers below were shoes, just when he saw the last layer, a very shallow brown trace attracted Da Zhao's attention.

"Give me luminol spray."

Zhu Xingxing hurriedly handed it to Da Zhao, and Da Zhao sprayed it evenly in the lowest compartment, and sure enough, the very shallow brown trace flashed fluorescence, and a fluorescent shoe print appeared below, which made Zhu Xingxing and Da Zhao a little excited.

"Bloodstains!"

Da Zhao nodded, his eyes stopped Zhu Xingxing's excitement, and he took out the photo of the footprints on the scene and compared it, the size of the pattern was exactly the same, and Da Zhao breathed a sigh of relief.

"What are you excited about, I'll take samples first and give me a physical evidence bag."

Da Zhao took out the two pairs of shoes below and placed them on the physical evidence bag, Zhu Xingxing came closer, helped Da Zhao, and sprayed the shoes with luminol up and down, but this time he was not so lucky, he picked it up and looked at it carefully, there was no fluorescent reaction.

"Huh? There's no blood on your shoes? ”

"Are you stupid, inside the surveillance, he knows that he will take off the blood-stained T-shirt as a mask to cover his face, and he will never keep his shoes, although it is expensive to destroy these things to save his life, you see these blood stains, they are on the top of the partition, and when he put his shoes in, he accidentally rubbed them.

Although I wiped the bottom of the compartment and disposed of the shoes, the blood still remained, such a shallow trace, if it was not easy to find at the time, I looked at the drawer above. ”

Saying that, Da Zhao stood up, pulled out the key on the cabinet door, tried a few times, and finally found the key to the drawer, opened it and found that it was full of certificates, teacher qualification certificates and certificates of various exams.

And in the other, there were some miscellaneous things, such as chargers and fans, as well as two envelopes, Da Zhao pinched the envelopes, one contained three thousand cash, and the other contained four or five supermarket shopping cards, one thousand face value.

Da Zhao turned his head, looked in the direction of the door, and asked in a loud voice:

"Call the director of the teaching and research department, and ask him whether the shopping card issued by the school for the New Year is still a gift, and there is a cash bonus?"

The director looked at Da Zhao and waved his hand busily.

"No, our school is short of funds, and we have been given rice and flour oil during the Chinese New Year, and there is never a shopping card or bonus, but ...... However, some teachers will take the initiative to tutor some children who do not study well, and many parents will say that we just don't advocate this, and the Education Commission does not explicitly prohibit it. ”

Da Zhao nodded, took pictures everywhere for evidence, and then checked the drawer of the desk, which was even more clear at a glance, and the things inside didn't seem to move very often, and he didn't find gold bars or large amounts of cash, bank cards or anything like that after cleaning it up.

Zhu Xingxing was behind, helping Da Zhao restore everything, and the two of them finished tidying up and left the office.

"Thank you for your cooperation, let's leave first."

The director stretched out his hand towards Da Zhao Yi, stopped their movements, folded his hands and asked with an embarrassed smile:

"That police comrade, I want to ask, what happened to Teacher Wang Hongwen?"

Da Zhao shook his head.

"Don't overthink it, we're just doing a routine investigation."

Speaking of this, Da Zhao paused, those few local scouts, one did not take the initiative to ask, Da Zhao also scratched his head a little, Zhang Chunbo looked at the ability to pull his hips, but the people who could be brought out, why didn't he take the initiative like this?

"I want to ask, Teacher He Dongmei, is she also from the English teaching and research group?"

The director nodded.

"Yes, it's also from our office, just like Teacher Wang Hongwen, who teaches English for the fourth and fifth grades."

"Please let the director recall, in the previous work, what was the relationship between Teacher He and Wang Hongwen, such as helping each other to substitute for each other, or carrying them home, eating together, etc., did they get closer?"

When the director heard this, he subconsciously glanced at the vice principal behind him, Da Zhao coughed, pulled off his mask, and smiled at the director and the vice principal.

"A few people, it's already past eleven o'clock in the middle of the night, and we don't want to delay too much of everyone's time, we just want to know the truth, do we still need to ask the leader for this?"

The director's cheeks trembled in embarrassment, as if he wanted to smile, but he really couldn't laugh, gritted his teeth and said very quickly:

"Let's put it this way, I was transferred from the third middle school at the beginning of 2009, and when I first came, I thought that these two people were two people, and they came to go together, and they ate lunch together.

I later learned that Mr. He was married, and her husband was not in the local area, and Mr. He told us that Mr. Wang was her husband's cousin, and they were working for another day, so we got closer, and we didn't think much about it, after all, our husband asked Mr. Wang to take care of him. ”

Da Zhao raised his eyebrows, this explanation made Da Zhao unable to say anything for a while, but why didn't he say anything when he found Wang Hongwen before?

After a few polite words, Da Zhao and Zhu Xingxing went downstairs and were about to leave, when Xu Dayuan's call came.

"Leader, you can't see it for a while, and you're worried about me!"

"Less poor, how about the on-site investigation?"
