In the interrogation room of the criminal investigation team, Guan Li and Zuo Ling were investigating Zuo Jiajia, while Zhao Yuean was standing in the observation room and looked at Zuo Jiajia intently.

"Where were you between 9 and 11 p.m. on Aug. 15?"

Guan Li glanced at the time of Guo Wenxin's death, and then asked.

Zuo Jiajia said without changing her face: "I study at home, and my parents can testify for me." ”

"Is it in your bedroom?"

Guan Li's sharp eyes looked directly at Zuo Jiajia and asked softly.

Zuo Jiajia's lips were tightly closed, her brows were slightly furrowed, and her voice was a little stiff and replied, "Yes." ”

"What is your relationship with the first deceased, Guo Wenxin?"

"Ordinary friends."

"Just ordinary friends?"

Zuo Jiajia said coldly: "I'm just a friend to him, and his thoughts have nothing to do with me." ”

Zhao Yuean looked at Zuo Jiajia, who was clenching her fists and her whole body in a defensive posture, and whispered: "It's quite clean." ”

Guan Li glanced at Zuo Jiajia and continued to ask, "What is your relationship with the second deceased?" ”

Saying that, Guan Li also intimately took out a photo of the rich second generation, which made Zuo Jiajia, who just wanted to deny it, shut up.

"He pursued me, I didn't agree, he kept harassing me."

"So, you're not close to the two deceased?"

"Yes."

Guan Li looked at her and took out the physical evidence bag containing the old ornament.

"What's going on here?"

Zuo Jiajia closed her eyes after a glance and bit her lower lip stubbornly.

"I picked it up."

"Does a family like yours still use you to pick up an ornament that is so badly damaged and put it in the bedroom?"

"I want to put on what I want, it has nothing to do with the case."

Zuo Jiajia said angrily.

Guan Li nodded and said: "What is your freedom, even if you picked it up, then why is there Guo Wenxin's fingerprint on it?"

Could it be that Guo Wenxin also picked up this thing? Or did you pick it up together? ”

Guan Li suddenly got up and leaned forward to look at Zuo Jiajia, which was a gesture of pressure.

Zuo Jiajia was silent, Zhao Yuean saw this scene in the observation room, and had once again confirmed the guess in his heart.

At this moment, Zuo Jiajia's father came to the criminal investigation team with a lawyer and asked Zuo Jiajia to exercise her right to silence and be represented by a lawyer. said that the criminal investigation team did not have any right to detain Zuo Jiajia.

At the same moment, the personnel of the Physical Evidence Section checked the physical evidence at the two crime scenes, and handed over the reports in duplicate to Guan Li in the interrogation room and Zhao Yuean in the observation room.

Zhao Yuean looked at Zuo Jiajia and listened to the excited roar of Zuo Jiajia's father in the hall.

said with a complicated expression: "Tell Guan Li that the case can be closed." Zuo Jiajia is the murderer, and the two cases are handled together. ”

Ten minutes later, Zuo Jiajia's father and lawyer were invited to the interrogation room, while Zhao Yuean and Guan Li were already waiting in the interrogation room.

Looking at Zuo Jiajia, who was crying with pear blossoms and rain, Zuo's father angrily controlled Guan Li, saying that he would sue Guan Li to intimidate his daughter.

Zhao Yuean looked at Zuo Jiajia directly on the side, and said slowly: "All the evidence is here, what else do you have to say?" ”

"I didn't! Dad, I didn't kill anyone... ”

Guan Li walked up to Zhao Yue'an and whispered, "Are you sure she will confess her guilt based on these alone?" ”

Zhao Yuean ignored him, walked up to Zuo Jiajia and said, "It's okay if you don't admit it, let's come little by little." ”

Saying that, Zhao Yuean put Guo Wenxin's related physical evidence bag on the table.

"A week ago, Guo Wenxin's body was dug up under the plane tree in the Baifeng community, and the body was dismembered in several pieces.

After forensic verification, the dismemberment was an afterhumous act, and it was mercury poisoning that really caused Guo Wenxin's death.

The medical examiner found an injection pinhole in Guo Wenxin's carotid artery and confirmed that he had been injected with mercury and died.

According to surveillance records, Huang Lin, the second deceased, had been near Guo Wenxin's house on the night of his death.

The police locked him up for the first time, and the day after Guo Wenxin's death, you met with Huang Lin, can you talk about something? ”

Zuo Jiajia didn't look at Zhao Yue'an with evasive eyes, and Zhao Yue'an didn't wait for her to answer and said directly: "If you don't say that I'll tell you for you, you used Guo Wenxin's death to threaten Huang Lin to give you hush money, but Huang Lin bit you back." ”

"What proof do you have...

Zhao Yuean opened a video in which Zuo Jiajia and Huang Lin were talking, and their conversation was also recorded.

"Huang Lin had a dashcam in his car, and you were talking at the front of the car, and the dashcam recorded your conversation and footage. Don't you admit it yet? ”

Zuo Jiajia closed her mouth with a pale face, and the father on the side was estimated to be choked by his daughter's anger, and his face was ugly.

However, Zuo's father still defended Zuo Jiajia and said: "That can only prove that An An found out that he killed that bastard, it was her friend, and it was normal for her to question." ”

Zhao Yuean sneered, at first tried his best to clear out that Zuo Jiajia and Guo Wenxin had a relationship, and then admitted that they were friends?

"Then how did your daughter Zuo Jiajia find out that Guo Wenxin was killed?"

"It's you who came to investigate...

"The police found Guo Wenxin's death at 3:17 p.m., and went to your house to do an investigation at 7 p.m.

And the video of Zuo Jiajia and Huang Lin was at 10:03 in the morning, before Guo Wenxin's body was dug up, how could she know that he was dead in advance?

And she knew in advance that Guo Wenxin was dead but did not call the police, she did not inform the police during the police investigation, and refused to admit that she had an intersection with Guo Wenxin.

What's going on? ”

Zhao Yue'an split his head and covered his face, and left his father speechless.

Zuo Jiajia's tears kept falling, biting her lip desperately.

Zhao Yuean saw that the fire was almost over, so he said softly: "Guo Wenxin committed suicide, right?" Or it can be said that you killed Guo Wenxin with Guo Wenxin. ”

Everyone present was stunned, and Guan Li asked puzzledly: "What do you mean that she is with Guo Wenxin... Killed Guo Wenxin? ”

Zhao Yuean picked up the syringe in the evidence bag and said: "This is the tool of the crime found in the garbage can in the alley, and there is only Guo Wenxin's fingerprint on it."

However, Guo Wenxin died from the carotid artery injection of mercury, and the angle of the pinhole was pierced from the top down, rather than flat or bottom-up.

It proves that Guo Wenxin was sitting in a chair at that time, and someone inserted a syringe into his carotid artery from above him.

There were only his fingerprints on the syringe, proving that it was he who was holding the syringe at the time.

On the whole, there is only one explanation, that is, Zuo Jiajia held Guo Wenxin's hand and injected mercury into it together. ”

Zhao Yuean asked Youjie and Jia Fan to do a simulation of the scene, and everyone looked at it stupidly.

Only Zuo Jiajia sat there with her head bowed, quiet and did not make any more sounds.

The original sound of sobbing gradually disappeared.
