Chapter 224: The Truth Is Getting Closer

When Xiao Hai described the situation that night, he thought that the letter should be written with Peyote extract, and after being torn to pieces by Lou Zhen, Zhang Zhiyuan would naturally clean it up thoroughly for fear of being discovered!

Judging from Zhang Zhiyuan's performance in plotting to kill Lou Zhen, he was a very meticulous and cautious person. After he collected the letter torn by Lou Zhen, he probably wouldn't throw it away casually. To prevent the police from discovering it, he should hide it in a place he considered safe!

Then, in Zhang Zhiyuan's heart, where was the safest? Under normal circumstances, most people would think their home was the safest place, but for someone like Zhang Zhiyuan, who had other women outside, he probably couldn't trust his wife, and he wouldn't choose to put it with his lover Huang Li. So, the safest place in his eyes, which he could see every day—naturally, it was his office!

Gu Changzheng tried his best to think about this matter from Zhang Zhiyuan's perspective and situation, feeling that he wouldn't easily trust others, and only he could make himself feel at ease.

So he thought of searching Zhang Zhiyuan's office immediately! The torn letter probably didn't exist anymore, but the "special" material Peyote used for writing was likely hidden by him.

Zhang Zhiyuan's office was different from other ordinary offices. It was simple and atmospheric, and there were no special bookshelves to decorate the facade. On the antique shelf behind the desk, except for the bottom row where some professional books were placed, other positions were placed with some ornaments like vases. Gu Changzheng touched them at will, but found that a cyan garlic-head bottle was heavier than other bottles!

This aroused his attention. He held the bottle in his hand and shook it a few times. The sound of objects colliding came from inside. Gu Changzheng leaned in front of his eyes and squinted to look. It was blurry, and there seemed to be quite a few things inside.

He called out softly: "Xiao Gao! Come here!"

Hearing this, Gao Ye walked over. Gu Changzheng said: "Find a container, there is something inside!" Gao Ye took a cup from the coffee table. Gu Changzheng turned the bottle mouth down, and only saw white small stones falling out of it, the size of grapes. Gu Changzheng continued to pour until all the stones inside were poured out. Gao Ye saw this and said: "Captain Gu, it's a pile of stones!"

"What is this thing?" Gu Changzheng suddenly pinched one of the stones with his fingers and said. Seeing this, Gao Ye took it, but it didn't feel cold and hard like a stone, but soft instead. When he pinched it with his hand, there seemed to be liquid inside.

"Look for it again, there should be the same fake stones here!" Gu Changzheng said.

Sure enough, 10 soft fake stones were mixed into this pile of stones!

"Take it back for testing. If I'm not wrong, this should be the thing that prompted Lou Zhen to jump off the building!" Gu Changzheng said indifferently.

———

"The test results show that the liquid in those plastic beads is indeed the extract of Peyote!" Old Zheng informed Gu Changzheng as soon as the results came out.

Gu Changzheng smiled slightly. It was indeed as he expected. The Peyote was in Zhang Zhiyuan's hands. Now all the people and clues that entered the police's line of sight after Lou Zhen fell were completely connected. Only the last node was missing, and it was also the most important one: how to prove that the forged suicide note was written by Zhang Zhiyuan, so that Zhang Zhiyuan would not be able to escape the crime of murder!

He was a bit unsure of Xiao Hai's true thoughts now. If it was said that his first confession was to cooperate with Zhang Zhiyuan and lead the disaster to Chen Junyang, why did he not mention the suicide note again this time? What was he hiding? But that "suicide note" was now locked in the evidence room of the bureau!

He shook his head, thinking not to think about this matter for the time being. As long as Zhang Zhiyuan confessed, these would be solved!

———

In the interrogation room, when facing Gu Changzheng again, especially when Gu Changzheng took out the white small balls filled with Peyote extract, Zhang Zhiyuan's face suddenly turned pale!

He knew clearly in his heart that although he had always claimed that Lou Zhen deserved to die, he didn't admit that he killed her. But now the police found the Peyote he hid, and he was indeed extremely passive. He originally wanted to guide the police to think that Lou Zhen jumped off the building after arguing with him, but now, I'm afraid his crime of intentional murder was inescapable!

Gu Changzheng looked at him quietly, seeing his face changing, knowing that he was still thinking about how to get through this hurdle. He didn't wait for Zhang Zhiyuan to think more and said: "Zhang Zhiyuan, this is the Peyote extract found in your office, a drug that will cause strong hallucinations after inhalation, right?"

Zhang Zhiyuan lowered his head and remained silent. Gu Changzheng knew he was testing how much he knew. He laughed softly: "Heh heh! You used this drug to write a letter, and it was in the name of your father! Because you know that although Lou Zhen is dissolute, she has a sense of gratitude to your father, so Lou Zhen will definitely read his letter."

Gu Changzheng saw that when he mentioned Zhang Zhiyuan's father, his body trembled slightly. Gu Changzheng continued: "But your handwriting imitation ability is too poor, or it may be that Lou Zhen is too familiar with your father. In short, Lou Zhen saw that there was a problem with your letter at a glance, so she tore that letter to pieces in a rage. But this mistake actually catalyzed the volatilization of the drug. Lou Zhen, as you wished, inhaled a large amount of the drug in a rage. Under the guidance of your deliberate guidance, she climbed onto the wall of the rooftop and jumped down!"

"Hmph hmph!" Zhang Zhiyuan sneered: "I don't know why your imagination is so rich. She jumped off the building herself because she felt sorry for our family, sorry for my father! Sorry for my mother! She was full of guilt, so she jumped off the building in a moment of impulse! What does it have to do with me?"

"You are still harboring illusions!" Gu Changzheng suddenly shouted, like a thunderbolt, shaking Zhang Zhiyuan's ears with a buzzing sound: "You think that because you didn't push Lou Zhen down with your own hands, her death has nothing to do with you? You have racked your brains, first letting Chen Junyang take the blame for the murder, and after the conspiracy was recognized by us, you wanted to mislead us into thinking that Lou Zhen jumped off the building herself out of guilt for your father. It's just that you have calculated everything, but you didn't expect that you left an important piece of evidence at the scene!"

Zhang Zhiyuan was shocked when he heard this and looked at Gu Changzheng. He saw the latter take out a transparent plastic bag from the folder beside him, which contained a piece of paper fragment with words written on it.

Gu Changzheng said: "Although you were very careful, you still left this fragment on the rooftop, and it just happened to leave one of your fingerprints! And the words on this, it was written with the things found in your office!"

This shocked Zhang Zhiyuan so much that he trembled, and he blurted out: "Impossible! I wore gloves to write it! How could I leave fingerprints!"
