The yawning Mo also rushed back: "What he said is basically true. As for the connection with the deceased, it is nothing more than that he mainly delivers food here, and the deceased often orders food, so he has delivered it to the deceased. Oh yes, and one more thing, this guy was diagnosed with cancer a year ago. ”

The delivery man, who had been removed from the suspicion list, was pulled back again.

"I remember when you asked him before, he didn't say anything about the key." Zhang Yichi reminded the Iraqi team, "It is possible that this detail was deliberately concealed." ”

"Then why did he hide it, if he was a murderer, would he be stupid enough to leave fingerprints on the key?" Team Yi had a bigger question, "Get him here, there should be some bigger secrets here." ”

Early the next morning

The man, Wen Shaobei, was summoned to the police station.

"Did you hide something from us yesterday?" This matter is very suspicious, and the Iraqi team, which has been working all night, did not sleep long before getting up again to inquire in person.

Wen Shaobei deliberately recalled for a moment before saying: "No, I'll just deliver a meal, and I've said everything I need to say." ”

"Are you sure you just delivered a meal and didn't do anything else?" Team Yi squinted and stared at Wen Shaobei tightly.

"What can I do, what the hell is going on?" Wen Shaobei's sad face.

Zhang Yichi on the side said: "After the deceased died yesterday, the murderer locked the door from the outside with a key, and then left the key on the door. After our identification in the evening, we found that the fingerprints on the keys matched yours. Can you explain why your fingerprints are on the key? ”

"This ...... I don't know, I just delivered a meal, I didn't touch his things, at most I touched the doorknob. Wen Shaobei was greatly wronged, and his voice suddenly rose to a higher tone, and his tone was a lot faster, "Everything I said is true, there is no deception!" ”

"Don't worry, we didn't say that you were the murderer, but because there were your fingerprints on the key, so there must be some connection here, we want to find out about it." Zhang Yichi comforted the emotional Wen Shaobei.

Mo Xuele pulled out a cigarette for Wen Shaobei: "Don't worry, the more anxious you are, the more you can't get things done." ”

"This isn't the first time you've delivered him food." Team Iraq asked again.

"Yes, this person basically orders two or three times a day, and sometimes I deliver it." Wen Shaobei gradually calmed down and replied.

"You didn't mention that before."

"You didn't ask, I didn't think it was anything, so I didn't say it." Wen Shaobei replied.

Team Yi was expressionless: "Did you find anything wrong with him when you contacted him before?" ”

"No, I'm just delivering a meal and taking a picture, and it's been so long, so many meals are delivered every day, I really don't know, and even if there is, I've long forgotten."

"Have you ever touched anything from him?"

"Not impressed."

Wen Shaobei's words are not flawed.

There is no obvious connection between his cancer and Meng Xiaoyang's case, and there is no way to draw any inferences from this point, so the Yi team did not mention it.

And the fingerprints on the keys are now almost incomprehensible.

If Wen Shaobei was the murderer of Meng Xiaoyang, there was no need to deliberately insert the key outside the door and leave fingerprints. This is not the same logic as a perfect crime, which is completely unmotivated.

However, the key was left outside the door, and there were Wen Shaobei's fingerprints on the key.

This is an indisputable fact, that is to say, Wen Shaobei is not only in terms of food delivery, but also in another unknown place and the case has a connection.

If Wen Shaobei is really innocent, then there is only one possibility.

The murderer deliberately left Wen Shaobei's fingerprints, so that the police suspected Wen Shaobei's head.

If this is the case, if the murderer wants to leave Wen Shaobei's fingerprints, he must first have contact with him.

"Have you been in contact with any strange people during this time? We suspect that the murderer may have somehow left your fingerprints on the door key of Meng Xiaoyang's house, transferring the murder suspicion to you. The Yi team deliberately talked about the idea, hoping that Wen Shaobei could recall it through this idea.

Wen Shaobei frowned and recalled, and after a while, he shook his head helplessly: "I really didn't pay attention to this, I didn't remember touching any keys at all." ”

"Have you been in contact with any of the other residents in that building?" Team Yi said.

"Uh......"

"Xiao Mo, take the information of those two key suspects." Team Yi beckoned and asked Mo Xuegang to take the high school students and middle-aged disabled people who lived in the same building as Meng Xiaoyang who were included in the key suspicions.

"Okay Team Yi." Unpredictable farts to get information.

After getting the information, the Yi team showed the photos of the two to Wen Shaobei: "This is a resident living in 120100, a middle-aged disabled person with a broken arm. This is a resident of 1602, a high school student. ”

"Uh...... Should it have been delivered? I don't remember, I've been a delivery boy for so long, and I really can't remember how many orders I deliver every day. Wen Shaobei looked apologetic.

After asking to no avail, he had to let Wen Shaobei leave again.

But this time it wasn't without results.

After Wen Shaobei left, the Yi team arranged for several people: "If the murderer deliberately framed Wen Shaobei, then the murderer must have been in contact with Meng Xiaoyang and Wen Shaobei." The high school student who focused on the investigation, as well as the middle-aged disabled person, should focus on investigating their contact circles, if they have contacted Meng Xiaoyang and Wen Shaobei, the suspicion will be much greater. ”

"Understood." Zhang Yichi and Mo Tu said in unison.

The easiest way to do this is to check through the order history of the food delivery app.

The middle-aged disabled man does not have a record on his mobile phone, and he does not even know how to operate the phone. Among the takeaway orders of high school students, one time was indeed delivered by Wen Shaobei, but that was four months ago.

Whether it is Wen Shaobei or the family of high school students, they can't remember the experience of having a photo shoot four months ago. After all, it's just a face-to-face delivery, and there's really nothing worth remembering for four months.

The trail in this regard was temporarily interrupted.

The Iraqi team began a survey of the residents of the two same buildings.

The high school student's name is Ge Jun. Usually studying, family pressure, world-weary, usually the only hobby is to watch reasoning, crime movies. After being investigated by the police and not having to go to class, he actually smiled happily and behaved extremely relaxed in the face of the serious police.

Cheng Zhiyong, a middle-aged disabled man, usually works in a relative's car repair shop, and the money is basically used to buy alcohol and drink. The house has not paid the electricity bill for two months, so it has been very dark. When questioned by the police, the drunken Cheng Zhiyong ignored the police and had an extremely bad attitude.
