Forensics

At ten o'clock in the evening, the villa in Zhengrong Fishing Farm was brightly lit up by the city police's car lights.

The people in the villa did not expect the police to come back and apply for a search warrant so quickly.

Gu Yanchen was still leading the team, but he ignored the politeness of the afternoon and directly asked the three of them to get into the police car.

Fang Jialiang was a little surprised: "Didn't you just ask us this afternoon?"

Lu Ying patted the door of the police car and signaled him to sit in: "Interrogation of witnesses is completely different from interrogation of suspects."

After all, Lan Jie is a famous lady, in order to avoid taboo, it was Bai Meng who brought her out.

Lan Jie raised her head and asked, "You mean my husband was murdered?"

Bai Meng didn't say much: "Please go to the interrogation room of the Municipal Bureau to clarify."

Among them, only Zhong Zhichun remained silent and followed the police out.

Gu Yanchen crossed his arms and leaned against the police car, watching him get into the car.

The rest of the people searched the inside and outside of the villa carefully, and even removed a U-shaped sewer pipe.

The city bureau in Penang has always been a city that never sleeps. Even at night, there are cases handling personnel coming in and out.

The three were quickly taken into the interrogation room and locked up separately.

Gu Yanchen deliberately left the three of them alone for a few minutes, checking everyone's reactions through the observation window.

This introspection link will aggravate the fear in the suspect's heart.

Then he personally interrogated Fang Jialiang, asked Bai Meng and Lu Ying to interrogate Lan Jie, and Zhong Zhichun also sent several police officers there.

The name, gender, age, place of origin, etc. were interrogated one by one, and then they were asked about the circumstances of the case in detail.

After a round of questioning, Gu Yanchen began to ask some important questions repeatedly, and if there was a slight flaw, he continued to ask.

The questions were asked very quickly, one after another with perfect logic, making Fang Jialiang unable to resist the questions. As the night deepened, he obviously felt more and more tired, and his brain began to slow down.

However, the more Gu Yanchen asked, the more energetic he was, and he continued to exert pressure.

Fang Jialiang is a pampered young master, he has never seen such a battle,

Gu Yanchen could feel that Fang Jialiang answered his question tensely all over his body, and saw the cold sweat dripping off his forehead.

In connection with the physical evidence and the results of the autopsy, Gu Yanchen has already deduced the truth to a great extent.

"Where were you that afternoon?"

"I'm in my study at home."

"What exactly did you do?"

"Use the computer in the study."

"The computer at home shows that there are only boot records after [-] pm."

Fang Jialiang paused for a moment, then whispered back: "I remember wrongly, maybe I read a book before that."

"Are you sure you haven't gone out this afternoon?"

"No." Fang Jialiang glanced aside.

"You haven't met Lan Jie?"

"No."

"Remind you again, don't lie." Gu Yanchen warned him.

When Fang Jialiang lies, his eyes will habitually look to the right.

When Gu Yanchen was chatting with Fang Jialiang in the afternoon, he didn't push him too hard. He tried his best to relax him, just to observe Fang Jialiang's normal state.

A man's normality is his baseline performance.Once the baseline performance is established by observation, it is very easy to determine which are abnormal reactions, and you can know whether the other party is lying.

Now, Gu Yanchen is making him nervous.

Under tension, people will reveal more flaws.Gu Yanchen can tell whether he has lied or not just by his demeanor.

One by one the lies were exposed mercilessly.Gu Yanchen showed Fang Jialiang a photo. Although he had turned off the surveillance at the entrance of the villa, a surveillance station upstream of the fishing ground still took pictures of his car. The photo was a bit blurry, and it was hard to see who was driving. The time of the photo was Three o'clock in the afternoon.

Fang Jialiang stammered and explained: "That was me driving to find my father..."

"Didn't you say you were at home all afternoon?" Gu Yanchen asked.

Fang Jialiang stammered even more: "No...no, I just went to find him, and then I didn't see him, so I came back by myself. It didn't take long, I forgot to mention it just now."

The time of death predicted by the forensic doctor was an hour after lunch.

According to the nanny's statement, that day was lunch at 11:30 noon, that is to say, the time Fang Zhengrong was killed should be before [-] pm.

Gu Yanchen deduced that that afternoon, Fang Jialiang drove to the river to dump the body, and the body in the trunk of the car should be Fang Zhengrong's body.In order to prevent suspicion from being seen, Fang Jialiang put on a fishing suit and stayed by the river for a while.

Someone saw a fisherman suspected of being Fang Zhengrong by the river, and it was probably Fang Jialiang in disguise.

But he just clicked on this question and didn't continue to ask.

In the absence of witnesses and conclusive physical evidence, he did not expect this question to overwhelm Fang Jialiang, as asking too detailed would risk inducing a confession.

He asked these questions now just to make Fang Jialiang feel guilty, and when his guilt and fear accumulated to the extreme, he would be able to overwhelm him by throwing out conclusive evidence.

After asking for another half an hour, Gu Yanchen faced him and filed charges: "According to the police investigation, you are the one who killed your father Fang Zhengrong."

After Fang Jialiang denied it, he produced evidence.

"After the night's search, physical evidence found fungoid foam from your father's mouth and nose on your clothes...How do you explain this?"

Fang Jialiang said with flustered eyes, "No...impossible." He has been extremely careful, changed all his clothes, and cleaned all the places.

Gu Yanchen's eyes locked on him, as if he had seen through all his lies.

Fang Jialiang's forehead was covered with cold sweat, and he hardly dared to look directly into Gu Yanchen's eyes.

After a stalemate for a while, Fang Jialiang gave up struggling, he stammered and asked, "Where is it stuck?"

Gu Yanchen solved the mystery: "It's the upper of your slippers." He already knew this, and it was only at this moment that he pointed it out leisurely.

Sure enough, the appearance of this physical evidence made Fang Jialiang's breath stop.

For a moment, he felt like a mouse being played with in a cat's claw.

All the roads around are dead ends.

"I... I don't know. Maybe someone else put it up on purpose, just to slander me."

Faced with the questioning, Fang Jialiang stopped cooperating, either saying he didn't know, or that he didn't remember, and even started talking nonsense.

Gu Yanchen, however, was very patient and continued to ask questions step by step.

In reality, there are not so many mentally strong people. Normal people who have killed people would feel guilty when they are interrogated repeatedly by the police. What's more, what he killed was his own father, and there is evidence in front of him.

After the murder, Fang Jialiang has passed the state of tension and numbness, and now only regret and fear remain.

His hands started shaking involuntarily.

Later, Fang Jialiang didn't say anything, but Gu Yanchen said for him: "The real place of your father's death was the bathroom of the guest bedroom on the first floor. The police found the most similar drowning in the sewer to Fang Zhengrong's death. That is also the evidence of the case. One. That afternoon, Fang Zhengrong suddenly returned to the villa while fishing, and ran into you and Lan Jie?"

The corner of Fang Jialiang's mouth twitched, and he was still resisting: "Officer Gu, these are just your guesses, I... I didn't kill anyone..."

Such an argument appears weak.

Gu Yanchen asked: "Is your father's death a careful plan or a whim?"

This is a multiple-choice question, but both ends of the question are dead ends.

Fang Jialiang's face was extremely pale, and his heart almost collapsed.

"Fang Jialiang, you should confess as soon as possible." Gu Yanchen threw another hole card, "If there is an accomplice, will she be able to withstand the pressure and not confess you?"

This is the classic prisoner's dilemma.

When the accomplices are interrogated separately and faced with different situations, their previous contract will be immediately broken.

Human nature cannot stand the test.

Fang Jialiang raised his head and asked, "Where is Captain Cao? Isn't he in charge of this case?"

Gu Yanchen: "The case has been transferred to the Municipal Bureau, and now our Special Criminal Division is in charge."

Fang Jialiang said again: "I want to see your leaders..."

Gu Yanchen chose to conduct a surprise interrogation at night because he was afraid that someone would do something bad: "Whoever comes tonight will not be able to protect you."

Fang Jialiang's body moved on the chair, as if he was fished out of the water, he murmured: "I want a lawyer."

Gu Yanchen: "Okay, I'll let you contact a lawyer. But if you make this request now, it sounds to me like a confession."

Fang Jialiang became a little irritable, stretched out his hands and hugged his head, in a standard surrender posture.

He said in a trembling voice, "I must kill him! I did it to protect myself, to...defense, justifiable self-defense. At that time, my father... wanted to get the gun in the storage room at the back. If he got it, I'm the one who died. I'm not lying, you should have found the gun."

Fang Jialiang held his head, remembering the panic when he pushed his father into the bathtub that afternoon.

Father's strength was great, and the body under his hands struggled unceasingly, reminding him of a fish that cannot breathe out of water.

The fish kept in the bathtub were all frightened, and kept swimming around in fright.

He was afraid of his father, and also of those slippery creatures.

He hesitated for a moment, but Lan Jie rushed in and pressed Fang Zhengrong together with him.

She screamed, "We've got to kill him! Otherwise we're both doomed."

Father reached out to grab something, but there was only the slippery bathtub around.

His body struggled up and down, and neither of them could hold him down.

Those were the most flustering minutes of Fang Jialiang's entire life.

By the time he realized it, his father had already crouched beside the bathtub and was motionless...

He waited for a while before mustering up the courage to turn his father over.

That was the first time he saw a drowned person. His father's skin was gray and white, and his body was wet. He was no longer a species like a living person.

Then, small white froth came out of my father's mouth and nose, piled up under his nose, and seemed to grow a white beard.Terrified, he tore off the paper and wiped it off, but more foam came out.

He became nauseous instantly, holding the sink and vomiting non-stop.

After a while, Lan Jie said: "There is no one else at home. He...he never came back. He drowned. He died in the fishing ground. No one will find out. He died at home..."

After the incident, he removed the body, left his father upstream on the fishing ground, cleaned the bathtub, washed the clothes, and discarded all evidence.

They thought it was perfect and there was no evidence left.

But it was still found by the police.

Twenty minutes later, Gu Yanchen came out of the interrogation room. Under great pressure, Fang Jialiang confessed everything.

After Fang Jialiang confessed, Lan Jie couldn't bear the pressure and recruited after a while.

She said that the water in the bathtub was the same as the water in the river, thinking that the forensic doctor would not be able to find out where Fang Zhengrong drowned.

Lan Jie's confession also revealed some secret things.

Before marrying Fang Zhengrong, she was originally Fang Jialiang's girlfriend.

Unexpectedly, Fang Zhengrong took a fancy to her and took her love with a knife.

Fang Zhengrong was extremely lustful, and he didn't restrain himself after marrying her. He looked for all kinds of beauties outside, and he didn't even let go of the female employees in the company.

Such behavior aroused Lan Jie's dissatisfaction, and the husband and wife often quarreled.

Once when she got drunk, Lan Jie started an affair with Fang Jialiang as if taking revenge.

The two originally planned that one was a wife and the other was a son. If Fang Zhengrong passed away, the inheritance would fall into their hands.

But just a few days ago, Fang Jialiang happened to pass by the study and heard the conversation between Fang Zhengrong and Zhong Zhichun. He thought about amending his will, and even thought about divorcing Lan Jie...

Coincidentally, two days later, Fang Jialiang was hanging out with Lan Jie, so Fang Zhengrong hurried home and caught the rape in bed.

An angry Fang Zhengrong quarreled with them.

Fang Jialiang was in the midst of the scuffle, and together with Lan Jie drowned Fang Zhengrong in the bathtub.

Later, they were afraid of being discovered, so they came up with the idea of ​​falling into the water when fishing, and threw the body in the fishing ground. They also pretended to be at odds in an attempt to hide their accomplice relationship.

The facts of the case soon came to light, and the police finished the confessions of the two and asked them to sign for confirmation.

Bai Meng turned around and asked Gu Yanchen: "It seems that Zhong Zhichun has nothing to do with this case. Shall we release him?"

Gu Yanchen said: "Let him go." He got up and took a coat, took out the lighter and said, "I'll go and release him myself."

Zhong Zhichun didn't seem to be surprised by the police's release. Gu Yanchen took Lu Ying and led him downstairs.The elevator stopped downstairs with a ding, and Zhong Zhichun stepped out.

It's just past midnight now, on a summer night, with the night wind blowing, there's still a hint of coolness.

Zhong Zhichun contacted the driver and stood at the side entrance of the Municipal Bureau, waiting for the car to pick him up, while Gu Yanchen was chatting with him.

Zhong Zhichun said: "I knew Captain Gu that you were able to discern every detail, and solved the case so quickly and cleared my innocence."

"This case is not complicated." Gu Yanchen looked at Zhong Zhichun and said, "Mr. Zhong, don't you care who killed Fang Zhengrong?"

Zhong Zhichun said: "Anyway, the person is dead now, I just need to know that I am innocent."

"Mr. Zhong is really kind-hearted. Someone died around him, someone killed someone, and he can still be so calm." Gu Yanchen slowed down his speech, "Besides, there are some things in this case that I haven't figured out yet... "
