() Major case series (4)

Everyone in the venue buzzed again.

"What makes me even more surprised is that when the technical team inspected the site, they found a broken plate fragment under a sofa. It was not big, only two fingers wide, and there were fresh oil stains on it."

"Just before the meeting just now, I inquired specifically, and after testing, those oil stains are consistent with the red oil used in the stewed vegetables of my brother's restaurant. I have to ask again, where did the broken plate go? Would it be difficult to walk out on its own? Besides, it couldn’t be found inside or outside the house. How to explain this? Therefore, my opinion is that there must have been a third person in the house at the time of the crime, otherwise, It is difficult to explain all the strange things I suspect above."

The venue was silent.

"Then, can you tell me what you need to do to further prove the existence of the 'third person' you mentioned?" Mei Haiyang asked calmly, suppressing the excitement in his heart.

"There is only one way to expand the radius of the survey and search, and conduct a comprehensive and carpet-like inspection of the scene. We must find out the whereabouts of the disposable lunch box and broken plates in the house."

……

In the early morning of the next day, twenty or so officers re-entered the chemical plant, and accompanied by the Dang Xiangjun and a small boss in the plant, they resumed the on-site inspection.

This time, the police cordon was widened, and there were police officers carefully inspecting along the perimeter of the factory.

More than two hours later, the inspection results of each team were summarized one after another. A person in charge of the team leader sighed and said to Dang Xiangjun who was following him: "Xiao Dang, the factory area and surrounding areas have been searched. From the point of view of reasoning, your analysis should be reasonable, but we have not found those physical evidences... It is even more regrettable that this also made us lose the only chance that we might be able to find clues."

Hearing this, Dang Xiangjun didn't know whether to be happy or worried, and he couldn't say anything for a while.It's just that I'm still thinking in my heart, if this "third person" wants to get out?Taking advantage of the fire in the dormitory, the doorman left when he left his post. It should be the best time.However, before that, where should he hide so that he can observe the guards without being easily seen?

While thinking, Dang Xiangjun accompanied the person in charge out of Zhao Xiaodong's dormitory, ready to send them away.

In the aisle on the second floor, the person in charge stopped in his tracks, smiled and asked the head of the factory, "Where is the toilet in the factory? It's convenient for me to go, so as not to be inconvenient if there is a traffic jam on the way back."

The little head pointed to a corner of the factory area and said, "Over there."

The factory is divided into two parts, the office area and the production area. Although both areas are within a wall, the two areas are roughly separated by a green belt. The toilet is built in a corner of the factory area.

Dang Xiangjun raised his head and measured it visually. The toilet is quite far away from this dormitory area, more than 300 meters away. Suddenly, he asked: "These comrades who live in this dormitory area usually run so old. Are you going to go to the bathroom?"

The little boss smiled awkwardly and said: "That's not true. Each of them has a key to the toilet on the first floor of the office building, and they usually use the toilet in the office building nearby. It's just that it's a holiday and the building is locked. I don't have the key to the building." .”

There is a side door on the side of the office building close to the dormitory area, which is usually a shortcut for people in the dormitory area to enter and exit the building.

"Oh, who has the key to the building? Does Zhao Xiaodong have it?" Dang Xiangjun asked.

"According to the regulations in the factory, there is no one except the doorman and logistics. When you need to use it, you must go to the doorman to get it. You know, the doorman is usually responsible for opening and locking the door on time. A door or something; logistics, mainly for the convenience of cleaning.”

"Section Chief Zhao Xiaodong, according to the regulations, he is not allowed to own the key of the building without permission, but I heard that he thinks it is troublesome to go to the guard every time to get the key, saying that he has a key for the side door, anyway, he is in charge of security. Well, no one pursued it."

This was later confirmed by security personnel.

Dang Xiangjun looked at the team leader guiltily and said, "We seem to have neglected the entire office building this morning."

It's no wonder that the factory employees are on vacation, and the office building is locked all the time. Who would think of going inside to search?

……

After further inspection, it turned out that a black garbage bag was found in the men's toilet on the first floor of the office building.As soon as I opened it, there were several neatly packed lunch boxes in the bottom of the bag. The four big characters of "Brothers Restaurant" were printed on the box, and there were all pieces of plates and discarded dishes inside.

Speaking of which, the recent holiday of the chemical plant really helped the task force a lot.First of all, the number of people entering and leaving has been greatly reduced. The entire factory area, especially the office area where the incident occurred, has not many people entering and exiting, so the on-site investigation will not be disturbed.Then the frequency of garbage removal was changed from once a day to every five days, which objectively preserved the evidence in the toilet.

The unexpected result is that during the detailed inspection of the office building, the technical team took several suspicious fingerprints from an old-fashioned door lock in the men's toilet on the first floor. After checking them one by one, only half of the fingerprints remained. Found the owner.

And among all the keys found in Zhao Xiaodong's belongings, none of them could open the side door of the office building, let alone the door lock of the toilet.

Where did Zhao Xiaodong's key go?

……

In Mei Haiyang's office, Dang Xiangjun further rationalized his analysis and judgment on Zhao Xiaodong's case according to the request of Mei's deputy detachment leader, and made a detailed report.

Before finishing the report, he said: "Now we can further prove that this 'third person' exists. The half of the fingerprints in the men's room and Zhao Xiaodong's missing key are all new evidence."

Mei Haiyang was noncommittal and asked, "Then, what direction do you think the investigation should take next?"

Dang Xiangjun rubbed his hands and said: "In addition to continuing to compare the half of the fingerprints, at present, we can only start with the people Zhao Xiaodong has been with recently."

Mei Haiyang handed a report to Dang Xiangjun, saying: "This is another case related to Zhao Xiaodong, the Gao Shulin case, that is, the "1.14" case, you should have heard about it. This latest report said that Gao Shulin's death The time is not when the crime happened, but more than 48 hours before the crime happened. What's more interesting is that the report said that Gao Shulin's body seemed to have been frozen. Interesting? I want you to help me untie it. Are you interested in this problem?"
