Don't take the bean bag as a police dog

Chapter 88
Under the bright sun outdoors, the women took up umbrellas to shade them one after another.

Zuo Dongliang watched the surveillance footage coming and going in the command center. It was indeed difficult to recognize the facial features of women outdoors. In addition to the protection of umbrellas, many women began to wear sunscreen masks.

As mentioned in the case analysis of the criminal investigation team before, because Diandong City is located on a plateau and the intensity of ultraviolet rays is high, most of the women in Diandong City have the habit of holding umbrellas. It is very difficult for girls, and the parents of the missing girl also said that the girl took good care of her skin, and even had the habit of holding an umbrella on cloudy days.

This also caused the video tracking to be unable to track the girl, which made it difficult to obtain evidence.

The umbrella seems to be an obstacle.

Judging from the physical evidence collected by Zuo Dongliang, there was an umbrella in the dormitory of the missing girl, which seemed to be heavily used, and the mask seemed to be used frequently.

Logically speaking, the missing girl must have traveled with another umbrella until she disappeared, and it is very likely that she also wore a sunscreen mask.

Therefore, finding that umbrella has become the key. According to the description of the parents of the missing girl, their daughter is very frugal and reluctant to spend money on a new umbrella, so if they can find another umbrella, the parents of the missing girl can still recognize it. .

From this point of view, the umbrella may be the key breakthrough.

In addition, the cosmetics left on the sunscreen mask may also be a key breakthrough.

But the crux of the problem is how to find the umbrella and mask used by the missing girl. To find these two things in the crowded city of Diandong with a population of 900 million, we can only rely on police dogs.

After Zuo Dongliang reported his conjecture to the criminal investigation team, Li Lei agreed to the direction of the investigation, but he had no manpower, so Zuo Dongliang could only call out the auxiliary policeman Liu Xiaoshuai who was still resting, and Zuo Dongliang promised to ask him Eat, and give him a disc of the latest PS5 game.

Originally, the police dog team was going to send another physical evidence search dog to carry out the investigation and search together, but now another murder case occurred in the township, and the search dog could only participate in the handling of this murder case.

As Yang Yong said, with the arrival of summer, criminal cases will also be on the rise. Fortunately, three new auxiliary police comrades have come, otherwise, it is estimated that this time next year will be severely understaffed.

So the task of searching for the missing girl's umbrella and mask fell on Zuo Dongliang and Dou Baotou.

Shen Jing has always been very concerned about the progress of Zuo Dongliang's case investigation. However, in terms of work discipline, at this time, he can't disclose the case to irrelevant personnel. Zuo Dongliang directly told Shen Jing about this, Shen Jing complained a few words, but kept silent Don't ask.

The first thing to do is to make his guess valid. Zuo Dongliang guessed that there must be sunscreen, hand cream and other cosmetics left on the umbrellas and masks.

If this conjecture is verified, then you can continue to investigate and let Doubao use these cosmetics as the source of smell to start tracking.

Zuo Dongliang first used hand cream and facial skin care products as sources of smell for Doubao to sniff, and then used the umbrella and mask that the missing girl kept in the dormitory as search objects to track down. He asked his assistant Liu Xiaoshuai to wear gloves and foot covers Umbrellas and sunscreen masks were hidden in places unknown to Doubao and Zuo Dongliang, to simulate a real search situation.

The reason for wearing gloves and foot covers is that Doubao is not allowed to find the above two items based on the smell of the soles of Liu Xiaoshuai's feet, but to let Doubao find the above two items based on hand cream, facial skin care products, sunscreen, etc., then the verification is considered successful.

The entire verification process needs to be carried out separately. First, search and verify the umbrella. The source of smell is the hand cream and sunscreen left on the umbrella, and then search and verify the sunscreen mask. The source of smell is various skin care products and other products left on the mask. cosmetic.

This process was carried out on the campus of Diandong University, where the missing girls often come and go, and there is a faint smell left.

Liu Xiaoshuai shouted on the intercom: "Brother Liang, I've already hidden in the campus, am I here to look for you or what?"

Zuo Dongliang was just about to say it, but he suddenly thought of an idea of ​​his own. He pressed the intercom and said, "Don't come back now, your gloves also smell like the umbrella handle. You hide the gloves too. See if Beanbag can find your gloves."

"Got it! Brother Liang!" Liu Xiaoshuai happily replied on the intercom.

Liu Xiaoshuai is now more active at work than when he was at work, probably because Zuo Dongliang promised to lend him the latest PS5 game disc and treat him to dinner.

In fact, Zuo Dongliang stopped playing that stuff a long time ago, and his console game career ended at the PS4. The so-called lending him a game disk was actually just buying it now.

In order to trick colleagues into helping, there is no other way. Now that the police force is tight, there is no way to spare manpower.

Liu Xiaoshuai likes to play all kinds of games. Recently he bought a PS5. Although he is taking the exam, this kid is reluctant to give up games that are not helpful for the exam. Although Zuo Dongliang reminded him, it seems to be of no use.

After Liu Xiaoshuai came back, Zuo Dongliang asked Doubao to smell the missing girl's sunscreen, and the search to verify the speculation officially began.

Since the last time he searched for fleeing oil rats in the mountains, Zuo Dongliang now pays attention to the wind direction to search. This faint smell and wind direction have a great impact on the police dog's search. If it is a downwind search, it is very likely. You will miss it, so Zuo Dongliang now has a small wind vane purchased online to monitor the wind direction.

Interestingly, on philosophical issues, headwinds are a disadvantage, but tailwinds are. At this time, headwinds become favorable conditions for the search for beanbags, and tailwinds are not good.

against the wind……

Tailwind...

against the wind……

In summer, the change of wind direction is a bit complicated. In addition, there are many buildings on the university campus and there are certain disturbances, so the direction can only be seen roughly. At this time, Doubao does not seem to have a clear direction, but is searching randomly. Liu Xiaoshuai, who was beside Zuo Dongliang, asked if the smell was too weak, and the wind direction was complicated, which was difficult for a strong dog.

Zuo Dongliang remained silent. He believed that the previous hard training would be useful. Doubao's current search and tracking ability has even surpassed its guarding ability. The strong performance in the search event in the International Working Dog Competition was not a flash in the pan. .

Zuo Dongliang thought, is it because when he smelled the hand cream and sunscreen for Doubao, he just smelled the mouth of the bottle, and the source of smell was not stimulating enough, so stop and squeeze the hand cream and sunscreen on the ground, let it smell Anyway, it is important to find someone now, and it is worth wasting these insignificant things. As long as you can find clues, or even find the missing girl, at worst, you can buy a set for the missing girl yourself.

After smelling this large area of ​​smell source, Doubao seemed to have an inspiration in an instant, and started to rush forward.

"I'll go, Doubao has found its status." Liu Xiaoshuai sighed behind Zuo Dongliang.
