Zhou Zhengcheng was anxious like a monkey scratching his heart at this time, and he was very curious.

Why is it so good, suddenly it has something to do with Xindong takeaway?

"After the person was lost, we re-monitored the elevator and found an abnormality in the past two days.

There was a delivery person, when he went to other floors to deliver takeaway, before leaving, he deliberately pressed the elevator button on the 5th floor and went out to watch for two minutes before leaving.

If it's when it's a takeaway, I can still understand that he pressed the wrong floor, but if he presses it again after the delivery, there is obviously a problem.

And he didn't press the 4th floor, he didn't press the 6th floor, but he pressed it to the 5th floor! ”

After listening to Wen Ce's explanation, Zhou Zhengcheng also felt that there was something wrong with this delivery man!

"Looks like we're going to take a good look at this delivery man!"

"What delivery man?"

Zuo Xu, who sent the backpack to the laboratory department, just walked to the door of the office when he heard Zhou Zhengcheng's words, and immediately asked curiously.

You know, according to the original plan, he ...... today No, it was already yesterday, and he was going to find a delivery man, but he was delayed by the sudden case.

Therefore, when he heard the three words of the delivery man, Zuo Xu paid special attention.

"It's nothing, it's not too early, let's deal with it in the office for one night first, and you have to go to the headquarters of Xindong Takeaway early tomorrow morning."

After Wen Ce saw Zuo Xu come back, he glanced at the time and found that it was almost three o'clock in the morning, so he said to everyone.

If you don't take a break, it's dawn.

After all, people are not iron-beaten, and after a busy day, they don't have a good rest, and if they don't hurry up and sleep for a few hours, how can they eat the next day?

"Hah~"

Zhou Zhengcheng yawned and said: "I'm really sleepy, if I sleep now, I can sleep for 4 hours, Xiao Zuo, you can also sleep for a while, or you won't be energetic tomorrow." ”

"Uh~"

Don't sleep,

You haven't talked about the delivery guy yet!

Also, why are you going to the headquarters of XD Takeaway tomorrow?

What do they have to do with this case?

Seeing Wen Ce and Zhou Zhengcheng, they all walked back to their fixed sleeping positions in the office and rested, Zuo Xu couldn't sleep at all, and could only listen to the sound of the rain beating the pipa outside the window.

How can you do this!

……

"Morning, Xiao Zuo, you woke up so early!"

Zuo Xu yawned: "Brother Zhou, early, I just went out to buy you breakfast!" ”

"Didn't sleep well last night? Also, it's your first time working overtime, and you definitely haven't gotten used to it yet. ”

After speaking, he picked up a bun that Zuo Xu bought and stuffed it into his mouth, without seeing anyone rolling his eyes at him at this time!

Didn't he sleep well?

He didn't sleep at all last night!

I don't have such an appetizing feeling, my brain thinks about things, and my ears are full of the sound of rain, so it's strange that I can sleep!

Even when the rain stopped, he knew.

"Where's Wen Tou'er?"

When Zhou Zhengcheng was about to get a bun for Wen Ce, he found that the person was missing.

"Wash your face in the bathroom!"

Zuo Xu also served them, these people toothpaste, toothbrushes, and face towels, that is a lot, and they really take the office as their home!

I had nothing but myself, so I went to the bathroom to rinse my mouth, and then rinsed my face with cold water to refresh myself.

Prepare your own toothpaste and toothbrush as soon as possible.

After breakfast, Wen Ce let him and Zhou Zhengcheng set off.

In the car, after Zhou Zhengcheng's explanation, Zuo Xu finally knew this problem that made him not sleep all night!

"This time, we will investigate all the delivery workers, and collect their fingerprints and footprints and other biological information at the same time.

Hearing this, Zuo Xu was also very happy, he finally didn't have to investigate the other party alone, as long as he followed the murder department, he could do his own things by the way!

That's nice!

The headquarters of XD Takeaway is located in the north of the city, about 30 minutes' drive from the Public Security Bureau.

When they arrived, the delivery workers happened to be on the morning shift, and when they saw the police car outside, everyone was a little curious, and they didn't know what the police car was doing early in the morning.

"We're from the Sheriff's Department, isn't your boss there?"

After Zhou Zhengcheng got out of the car, he pulled the electric car of a delivery man and asked.

"I don't know, you can call the boss."

"What's your boss's phone number?"

The man pointed to the car that had just arrived behind Zhou Zhengcheng and said, "Our boss is here." ”

After the boss of the heart-warming takeaway got out of the car, he saw a police car parked at the entrance of the company at a glance, and two uniformed detectives standing next to him, and immediately sped up his pace:

"Hello sheriffs, ...... you guys?"

"You're the owner of Heartbeat Takeaway? Name? ”

"Exempt, surnamed Yang, Yang Jianmin."

Yang Jianmin heard the other party mention Xinding takeaway, and knew that they were really looking for him, and after looking at the curious eyes of the delivery people around him, he proposed: "Come in and have a cup of tea, standing at the door is not hospitality." ”

Zuo Xu and the others did have something to cooperate with Yang Jianmin, so they did not refuse, and readily agreed.

When the group came to the office, Yang Jianmin poured the tea himself: "It's not a good tea, don't dislike it, which department are you?" ”

"Mr. Yang, don't be polite, we are from the homicide department, and this time we came here, there is one thing that requires your cooperation."

Homicide?

Hearing the other party's origin, Yang Jianmin was obviously stunned, this murder place, just by hearing the name, you know what's going on.

Getting involved with them isn't a good thing, is it?

Thinking of this, Yang Jianmin asked a little nervously, "How do you need me to cooperate?" ”

"Recently we are investigating a homicide case, and there are clues pointing to the delivery people of your company, in order to rule out suspicion, we need you to gather them so that we can collect fingerprints and other information.

Of course, in order to prevent the grass from startling the snakes, this time they were summoned to collect fingerprints and other information, which can only be requested in the name of public security management. ”

Sure enough, hearing Zhou Zhengcheng's request, Yang Jianmin knew that he had guessed correctly, it was likely that his employees had committed the crime, and the detective came to the door.

"I understand that it is the duty of every citizen to cooperate with the management of public security, so when will we start?"

"The sooner the better, I have only one request, since September, all delivery workers in your company must collect biological information, and if there are people who have left the company, you also need to submit a list to me."

"Understood, then I'll make arrangements, I'll call all the people in the middle class first, and then replace the people in the morning shift when they're done, what do you think?"

In order not to affect the city's takeaway delivery, Yang Jianmin's method is the most suitable.

"You can arrange it, the security team will come over immediately, and you can arrange a conference room for them to collect."

"Okay, you guys have some tea first, and I'll arrange it."

After another half an hour, the people from the security team had already come over with the collection equipment and put them in the conference room arranged by Yang Jianmin.

After receiving the notice, a succession of delivery people rushed over.

In the conference room, they collected a series of biometric information, such as fingerprints and footprints, at the request of the sheriff.

And Zuo Xu was not idle, every time he went in, he would take a closer look at whether there was the person he met the day before yesterday.
