Chapter 448 - 448 413 Cracking the Case_2

448: Chapter 413: Cracking the Case_2 448: Chapter 413: Cracking the Case_2 This is the trouble with not having enough hard power; you have to find an alternative path.

Zhang Qi asked Qian Mingyu and the other two trace examiners, and naturally, they all supported Jiang Yuan’s judgment.

Unwilling to concede, Zhang Qi asked, “Is it possible that someone was carrying a dog or encountered a dog and took it away?”

If this case didn’t involve a death, at most it would be a case of serious assault.

If they could also eliminate the K9 unit’s work, that would be great.

Jiang Yuan shook his head slightly: “There are no signs of a dog at the scene, no paw prints, no fur, and the footprints that come and go do not support carrying anything in one’s arms.

When we catch the person, we can ask and see.”

“Are we going to make the arrest?” Zhang Qi hesitated a bit.

“You discuss it with your squadron leader.” Jiang Yuan didn’t care who made the arrest.

But arresting someone was still necessary.

The standard for minor scuffles at the police station was minor injury, that is, injuries below the level of serious injury class II.

Once someone was beaten to the point of sustaining serious injury class II, they would have to be placed in detention.

As for claims of self-defense, the standard for judgment was so strict that the average person couldn’t meet it.

In any case, not fighting was the most sensible way to communicate.

If you must fight, picking them up and spanking them was the safest way.

Zhang Qi made an “Eh” sound and turned to make a phone call.

Inside, he felt indescribably uncomfortable.

The dog hadn’t even been seen yet, and here was another case of serious assault.

If it weren’t for the fact that interrogation by torture was frowned upon, all the dogs in Miao He County would have to be renamed Guihua!

The squadron leader was already on his way when he received the call, and he hurried over quickly.

“How is it going?” The squadron leader, Xu Xuewu, asked in a loud voice, sounding very positive.

Just in terms of personal image and charisma, Xu Xuewu was surely at the LV3.9 level.

Jiang Yuan nodded to Xu Xuewu and the accompanying officers: “Currently, our preliminary judgment is that this is a scene where two people engaged in a fight.”

“How do you determine that it’s a fight scene between two people?” Xu Xuewu asked.

“The bloodstain analysis clearly shows,” Jiang Yuan gave Xu Xuewu a polite smile.

Besides that, he didn’t offer the muggles any further explanation on the application of forensic magic in an opulent, open-style building with clear skies.

Xu Xuewu made a sound of understanding, much like seeing a computer for the first time, and immediately began studying its working principle, trying to find a person or a mysterious crystal inside the machine case.

By this time, Qian Mingyu had already collected a dozen cotton swabs, straightened his back, stuck out his buttocks, reminiscing about the girls he had chased in high school and said, “What Captain Jiang is talking about is bloodstain analysis.

When I was studying, several teachers talked about cases they had solved, and it was thrilling.

I couldn’t wait to graduate and start working to clean up the world.”

“What happened afterward?” Xu Xuewu loved to hear stories.

Qian Mingyu sighed and said, “After that, the teachers introduced us to the fact that the density of human blood is 1.050 to 1.060, the pH value is 7.3 to 7.4, and the osmotic pressure is 303.7 millimoles per liter.

Look how clearly I remember it.

I even looked it up in a book to check, and the teacher was right.

However, because I went to look it up, I didn’t hear the rest, and when I listened again, I couldn’t understand.”

“Same here.”

“Pretty much.”

The two trace examiners expressed that they had similar experiences.

Xu Xuewu nodded absent-mindedly, recalling the courses he had taken in college which seemed to follow the same format.

Well, that’s fine; it seems most people are the same.

By this time, Jiang Yuan had already finished a careful survey of the surroundings and slowly said, “Based on the blood, the incident should have occurred about seven days ago.

I’m inclined to think it happened in the afternoon or evening, as can be seen from the coagulation state and the degree of separation of the blood.

Judging from the amount of bleeding and the footprints here, one probably ran first, and the other received support and then retreated.”

As he spoke, Jiang Yuan moved his hand through the air, tracing the scene.

Mu Zhiyang, holding the camera, busily noted down all the places Jiang Yuan pointed out.

Zhang Qi, just regaining his composure, widened his eyes, observing the surroundings as if he only saw one line of text—Answer: Omitted

Jiang Yuan, addressing the camera and Qian Mingyu, continued, “Both sides are likely not common folk.

One used a very sharp dagger, and the other fought barehanded and didn’t retreat, occasionally counterattacking and holding on until backup arrived before leaving.

Although they lost a lot of blood, I think neither of them died.

It’s very likely they both have priors.”

“A gang fight?”

“Something like that, it feels a notch higher in sophistication.

It was a fight with deadly weapons,” Jiang Yuan paused, then continued, “The total blood loss for both parties could be about 2000 milliliters, with one person contributing the majority of it.”

Ordinary people donate 400 milliliters of blood, and in special circumstances, up to 800 milliliters can be drawn—which is quite a lot—and this is under controlled quiet conditions.

If two people fighting lost more than 1000 milliliters of blood and didn’t faint, they both must be in excellent physical shape.

After looking for another minute or two, Jiang Yuan gestured with his arms in the air and said, “The person with the dagger, it’s very short.

They could use both hands, and there was a switch in use at some point.

The other person might have taken advantage of the dagger to injure the one holding it.

If we look at it this way, the attacker is slightly younger, 25 years old, 165 centimeters tall, 130 pounds.

This person must be self-conscious about their height, going so far as to wear height-increasing shoes when coming out to kill.”

“The attacked person, well, from the scene, it looks like they were ambushed.

The victim is 38 years old, 180 centimeters tall, 200 pounds, muscular, a weightlifter type, with shoe sizes 44 or 45, pretty big feet.”

“Check the DNA; you might match it.

Then look for hospitals.

With such serious injuries, one week to heal is not easy; they’ll need to recover for some days.

And since the injuries are from fighting, if the hospital didn’t report it, you’ll need to check the clinics.”

As Jiang Yuan spoke, Mu Zhiyang lifted the camera to record.

After he finished speaking, Zhang Qi, partly understanding and partly not, asked, “How do you figure that out?

Can you really determine height and age?”

He had asked similar questions all day long.

Jiang Yuan wasn’t surprised and casually explained, “I used the footprints to determine height and age.

The warehouse has a lot of accumulated dust; it’s quite clear to see.”

“I see…” Zhang Qi muttered to himself, then turned and said, “But about the injured person you mentioned, I think I might have a guess who it is.”

Zhang Qi was a local and deeply familiar with the situation in Song Alley.

He pondered and said, “There’s a small logistics center up ahead.

The largest fleet there is owned by Jia.

He often gets into fights and is a regular at the police station.

He’s usually a bit aggressive, and his height and weight match.”

The more Zhang Qi spoke, the more enthusiastic he became, suddenly finding the day’s weather quite nice and his mood very buoyant.
