"Thanks to book friend "Xiaojie Wuji" for the 2 monthly passes."

Xie Yu, who wanted to ask for proof, directly asked: "Senior Xiaonian, how do you know this? Is it just based on the footprints on the ground?"

"But I think the footprints are at least 44 yards. According to the footprint analysis, the murderer should be over 1.8 meters tall!"

Sean put his notebook and pen back in his pocket and said, "That's the theory, but this guy is pretty smart!"

"The murderer deliberately wore shoes that were a few sizes too big, but it was determined by his stride, shooting angle, and standing shooting posture."

"The actual situation tells me that the murderer is actually only 1.7 to 1.75 meters tall! He is about the same height as you."

After Xie Yu made some gestures, he felt that this was what happened, but then asked: "Well, senior Sean, it seems that you can judge the height by the distance between the footprints, but what is the shooting posture you mentioned?

!”

Sean shrugged and said, "I'll report the situation to Agent McCallion first."

After speaking, Sean grabbed the reinstalled communication device on his shoulder and said: "Police number pc26047, Sean and his partner Carl found a silver revolver at the skylight of the first three-story residential building on the west side of the warehouse.

Agent McCauley, please come up!"

Not long after, the communicator rang: "I am Agent McCallion, I will send someone over now, you guys stay there first!"

"Copy that!" Sean finished.

He looked at Xie Yu, pointed to the ground on the edge of the roof, and said: "Karl, I will give you a good one today. This is experience and cannot be learned in books."

"Karl, you see, although the murderer's footprints are very shallow, you can still see that the marks in the direction of the toes are darker than the marks in the direction of the heels. What does this mean?"

Seeing that Xie Yu didn't see anything yet, Sean could only continue: "This shows that the murderer once stood on his feet when shooting or observing the deceased."

"If you look at the height of the wall stacks at the edge of the building, combined with the angle of observation of the deceased, and the mark of the stride on it, you can get his height!"

Xie Yu thought for a while, simulated it in his mind, and said with gestures: "Senior, it seems to be true. In this way, I understand a little bit."

"By the way, senior, you said he is a soldier? What's going on?"

Sean said: "Hey, this is pure experience. Carl, you may not know that I have served in the Marine Corps."

"I know some of the behavioral habits of a soldier. I can tell from two points."

"First, the murderer used a Colt Python revolver. Although it is relatively powerful, it is generally kept as a collectible by enthusiasts."

"Being able to use this kind of gun to hit the target directly in the head thirty meters away shows that the murderer's marksmanship is very good, at least he has practiced it for a long time."

"Second point, the most obvious thing I noticed just now is that the murderer climbed up to the skylight through the rainwater pipe, shot the dead man, and then left quickly. This is a typical military style."

Xie Yu wanted to refute, saying that circus firefighters like climbing rain pipes could also do it, but she really felt that there was some truth in what Sean said, and it was a bit unreasonable to argue on his own.

Sean just wanted to continue talking to deepen his judgment on the murderer.

I just heard a noise behind me and turned around to see two agents in civilian clothes walking up from the stairwell.

The two detectives didn't say anything, they just flashed their police badges and walked up to Sean and Carl. They found the pistol on the dirty, broken glass and the ground.

"Okay! Thank you for your help, you two. The rest of the work will be left to us. You can go home from get off work," one of the agents said.

Xie Yu was about to speak when he was suddenly stopped by Sean, who then said, "You're welcome, this is our job too."

After getting off the residential building, Xie Yu quickly saw that the area had been cordoned off by the police. Many people rushed over one after another, including forensic experts, forensic doctors, police, etc., with police lights flashing.

Yes, it’s really like what’s shown on TV.

Xie Yu was about to take a look, but Sean immediately grabbed Xie Yu and said, "Karl, we are patrolmen, and the rest of the matter is not our responsibility."

Xie Yu: "But, but,..."

Sean: "I'm a little reluctant, Carl."

Xie Yu nodded fiercely, realizing that being a police officer was quite interesting.

Sean smiled proudly and said: "Little Carl, just don't give in. I like people who don't give in. By the way, Karl, do you want to be promoted?"

Xie Yu said unexpectedly:

"Promotion?"

"Of course I want to get promoted. Who doesn't like getting promoted!"

Sean: "That's good. I just wrote down the gun number."

Xie Yu: "Senior, this is to investigate the case privately. Doesn't this seem to be against the rules?"

Sean: "Is it against the rules?"

Soon the two reached a consensus.

…

According to Sean, the Silver Python series revolvers are still relatively niche in the pistol collection market and are generally sought after by some cowboy enthusiasts.

Especially after knowing the gun number, Sean quickly drove Xie Yu to the intersection of Bull Street and Sisko Street.

After parking the car, Sean led Xie Yu through a five-story department store and arrived at the warehouse area behind the department store.

After turning two more corners, Xie Yu immediately saw a red brick gun shop with steel guardrails on the windows. The signboard said "Dad Cowboy". Xie Yu felt that the name was a bit funny.

Xie Yu: "Senior Sean, is this right here?"

Sean smiled proudly: "Karl, don't underestimate this small gun shop. This old gun shop is very famous in Sacramento. It can be said that as long as you want the arms, even standard military equipment, Old

Dad can get it for you."

Xie Yu: "It's so awesome, why haven't I heard of it before?"

Sean: "Hey, this is what I found out when I was a private detective. Most people, even in the police station, don't know about it. Whatever you need in the future, Carl, you can come here. I will vouch for you in a moment."

By the way, sign up for a membership here.”

Xie Yu: "Get a membership? Senior Sean, why should I get a membership?"

Sean said awkwardly: "First of all, it's convenient. Carl, you can come here to buy any equipment in the future. The price is better than other supermarkets."

"Besides, aren't we investigating the case now? If you don't become a member, how can we investigate the case?"

Xie Yu: "Um, senior, can't we show our police badges?"

Sean looked at Xie Yu like a fool and said: "Karl, my little Karl, silly Karl, you don't think it's okay to show your police badge anywhere. If you show your police badge here, I guess you will be arrested."

type it out."

"Of course, if you become a member and show your police badge, there may be some discounts."
