Wu Cuo didn't want to disturb him, so he turned to Bai Yun and said, "Sister, then next, let's start by investigating Tang Lipei's interpersonal relationships?"

If nothing else, just the nature of this guy's work...... I guess a lot of people would love him to die...... Relationship research will take some time. ”

Bai Yun thought so, nodded and said, "Anyway, the people of our branch are at your disposal." As for me...... I have been following up on Wu Qiong's interrogation, and I can't let go of it here...... It feels like a breakthrough is about to happen......"

"Wu Qiong? Or forget it, right? Yan Ruyu shook her head, "Her suspicion is not as big as she imagined. ”

Bai Yun was a little displeased, "It's too early to say this now, don't forget the fingerprint on the steering wheel as a key evidence." ”

Yan Ruyu said: "No matter if there is any little fresh meat involved, it cannot be denied that Wu Qiong and Tang Lipei are boyfriend and girlfriend.

Since there is such a relationship, it is not surprising that Wu Qiong's fingerprints were found on anything from the deceased Tang Lipei.

There are Wu Qiong's fingerprints, maybe ...... On the contrary, it shows that the murderer knows the relationship between Tang Lipei and Wu Qiong very well, and uses or even deliberately blames Wu Qiong. ”

"What do you mean...... The murderer is an acquaintance of the two? Wu Cuo asked.

Yan Ruyu shook his head, "Let's ignore this first, this conjecture is too immature."

Again, we're focusing on the modus operandi, the modus operandi...... How so? With such a science and engineering style.

The murderer's behavior was logical, and he even arranged such a secret room that could not be seen for the time being...... As for Wu Qiong's ......" Yan Ruyu said while checking Wu Qiong's information on her mobile phone: "I dropped out of school early, messed around in the entertainment industry, and played tricks, until I met Tang Lipei, I started to have a serious career, and I also got on several hot searches under Tang Lipei's planning."

What do you think...... How could she use such a murderous modus operandi? ”

"Doesn't she have a helper? That little fresh meat. ”

"Little fresh meat? As long as you are not crazy, there must be a motive for killing.

Color, he has been deceived.

Money and fame, can he get these by killing Tang Lipei? Don't talk nonsense, Wu Qiong himself is not in the stream, even if he helps him with all his might, how much can he play?

As for love, these two people who use their feelings as bargaining chips get together, can they drive out and kill people for love? …… Hehe, don't talk nonsense. Yan Ruyu didn't want to continue to dwell on this issue, "Let's screen interpersonal relationships, Lao Wu is right, there is a long queue of people who want to kill Tang Lipei?" Think about the first-line stars who ruined their careers by him and are now like rats crossing the street, Wu Qiong's motive for killing...... How old is the tender chops? ”

Bai Yun was a little unconvinced, "I didn't say that the murderer must be her, it's just that she is the most suspicious, and now she is trying to find a way to eliminate her suspicion...... Besides, after talking for a long time, the suspicion of suicide and accident has not been ruled out. ”

"Okay, there are no absolutes in everything, I won't say anything to death," Yan Ruyu no longer retorted, "The most important task at the moment is to solve the problem of the secret room first." ”

As he spoke, Yan Ruyu's gaze was already fixed on a vent in the garage.

The vents are small and look only the size of a palm.

Estimated to the naked eye, ironclad cannot accommodate a single person to pass.

"Can this get to the outside?" Yan Ruyu asked.

As he spoke, he had already walked up to him, craned his neck to look at the barbed wire fence at the vent.

Bai Yun said: "It's too small, it's almost the same as drilling a kitten, people have to talk...... It can't have escaped from there. ”

"I'm just thinking that since there is a vent, Tang Lipei is not so easy to suffocate to death.

This is a planned and prepared crime, and the murderer will block the vents in advance. So, Lao Wu, go up carefully and see if there are any traces. ”

Wu Cuo understood, and the criminal police who moved from the door of the garage to the scene of the investigation of the sub-bureau left a spare herringbone ladder and quickly climbed up.

"Yikes!"

Wu Cuo reached out and tugged at the barbed wire of the vent, which looked like it should have been nailed to the wall by screws, but it was directly pulled off.

Wu Cuo took the barbed wire fence and made a gesture at the entrance of the cave, and said a little lost: "This thing...... That's how it seems to be designed...... Snap it up at the angle of the edge and drop it when you pull it. ”

"Haven't you done anything?" Yan Ruyu asked.

"Nope."

Wu Cuo took the flashlight handed over by Yan Ruyu with some excitement, and at the moment when he was about to turn on the flashlight and shine it in, a gray rat suddenly rushed out and went straight to Wu Cuo's door.

"Grass!"

Wu Cuo was frightened by this sudden change, his upper body suddenly dodged backwards, stepped on the ladder, and couldn't move under his feet, his center was unstable, and he fell down instantly.

Fortunately, Yan Ruyu and Bai Yunyan were quick to move, and they set him up one by one.

The big rat, apparently afraid of people, rushed out of the hole, scratched its paws several times in the air, and fell on the roof of the car with a thud.

It was not a light fall, but it had already identified its target, and its paws scratched the roof of the car a few more times, and then fell to the ground, rolling and crawling to the garage door.

In the blink of an eye, the rat was gone.

A false alarm.

Wu Cuo wiped the sweat from his forehead and climbed the ladder again. This time he turned on the flashlight at the beginning.

With one hand shining a flashlight in it, and the other hand in front of his face, he will not let any more living creatures living in the pipes escape.

This time, it's an unobstructed view.

After entering the entrance, the ventilation ducts have become noticeably wider, but they are still not large enough for people to pass through.

"How? Did you find anything? Yan Ruyu asked.

"The dust in there...... There are traces on it...... But ......" Wu Cuo organized the language, not knowing how to describe it.

"Doesn't look like it's left over from animal activity?" Yan Ruyu asked.

"Hmm."

"Come down and let me see."

Wu Cuo climbed down and instructed: "You slow down, be careful, if you can't jump down, I'll support you underneath." ”

Yan Ruyu glared at him, "Father Wu, don't be so nervous, I'm just worse than you, and I'm not paralyzed." ”

Yan Ruyu climbed up the ladder and first observed the hole, and there was indeed no trace of being pried, and there was no place to put on the screws.

He shone his flashlight again and observed the shape of the dust in the ventilation ducts.

With just one glance, he could see that it was a sign that someone had crawled.

Under the square ventilation duct, there are even traces of left and right open bows and crawling, rubbing the dust into a clear shade.

Yan Ruyu believed that with Wu Cuo's professional track examination, he must have instantly seen that this was a trace left by man.

What makes him uncertain is, who can crawl in such a narrow pipe?

Is it a child?

Yan Ruyu suddenly remembered the very famous "White Night Walking".

Was the murderer really a child?

He lowered his head to meet Wu Cuo's gaze and glanced at him.

Wu Cuo rarely saw such an expression on Yan Ruyu's face, hesitating, uneasy, and confused.

It seems that this time I really encountered an interesting case.
