Chapter 166 Double Clues: Key Evidence

"We have conducted a large-scale search of the parking lot. We searched all the trash cans and every corner of the parking lot, but there was nothing there! We also asked the cleaners and security guards, and they all said they had never seen this thing." Xiao Zhang complained.

"There are still places we haven't searched." Fang Rui said, "We didn't search those cars."

"But those cars were locked, how could he put it in the car? Anyway, we have checked under every car, and there is nothing hidden."

"Ding Zhuangzhuang used to work in a repair shop. Is he good at picking locks?"

Xiao Zhang and his friends took the photo of the refrigerator and searched the cars in the parking lot one by one, and even the car that drove out after the incident was screened again.

After a day, they finally found a suspicious vehicle. Through the car window, you can see something wrapped in a black plastic bag in the trunk of the car. It is square in shape and small in size.

There is no sign of the trunk lock being pried open.

According to the vehicle entry and exit records, they found the owner of the car. After contacting the owner, he said that he was one of the shop owners in the mall. He went out to travel recently, so the car was parked there. He has a spare key in his store. After

opening the trunk, they opened the plastic bag and found a small pink refrigerator inside, which was the refrigerator that was missing in Sun Xiaoning's car.

Everyone was happy, and finally found evidence to identify Ding Zhuangzhuang.

Xiao Wang carried a toolbox and excitedly surrounded the refrigerator, "Don't move, don't move! Let me check for fingerprints first."

"He must have worn gloves when he killed someone, how could he leave fingerprint evidence?" Xiao Zhang retorted.

"There are quite a lot of fingerprints on it." Xiao Wang detected a lot of fingerprints on the refrigerator.

"This can only prove that this refrigerator has not been wiped for a long time."

"..."

After taking the refrigerator back, Mu Mian sprayed luminol reagent on the outside and inside of the refrigerator. Soon, several fluorescent reactions appeared on the outside of the refrigerator. The area of ​​fluorescence was very small and in the form of drops. It should be a splash-type bloodstain.

"There are bloodstains." Chen Xue said excitedly.

Mu Mian was not as optimistic as she was. "Chen Xue, do you remember how Wang Yonghua died?"

"He was hit on the head by a wrench."

"This is a splash-type bloodstain." Mu Mian reminded.

"Yes, this could also be Wang Yonghua's bloodstain. That's right, the murderer couldn't be so careless and hurt himself when committing the crime, leaving his DNA evidence at the scene."

Xiao Wang detected a lot of fingerprints, and those fingerprints belonged to eleven people, but none of them could match Ding Zhuangzhuang's fingerprints, nor did they match Chen Yuankun's fingerprints.

"Xiao Wang, I said it a long time ago, the murderer couldn't leave fingerprint evidence. Wearing gloves when committing a crime has become criminal common sense." Xiao Zhang sighed.

Xiao Wang rolled his eyes at him, "So, you think my work is meaningless?"

"Of course not. There are also many criminals who are stupid and have no common sense."

"..."

The blood test results came out quickly. As Mu Mian expected, the bloodstains on the outside of the refrigerator belonged to the same person, Wang Yonghua.

"There is no evidence on the refrigerator, so why did Ding Zhuangzhuang hide it?" Xiao Zhang complained.

"Besides fingerprints and DNA samples, what other evidence can prove his identity? And this evidence is not easy to be destroyed. It is closely connected with the entire refrigerator."

Everyone was disappointed. They thought that finding the refrigerator would give them evidence to convict Ding Zhuangzhuang, but they still found nothing.

"We only checked the outside of the refrigerator, and we haven't checked the inside." Fang Rui said.

"We checked inside as well... Wait, you mean, take the refrigerator apart and have a look?"

Fang Rui handed the refrigerator to the technical department and asked them to take it apart to see if there were any clues.

There were some clues in the case of Chen's father falling to his death from the ladder. The shopkeepers near the supermarket said that they heard the sound of welding the morning before Chen's father's accident. That morning, Chen's father went out to buy goods, and Chen Yuankun did not go to the supermarket. Only Chen's mother was in the supermarket.

The answer was obvious. The person who destroyed the ladder was most likely Chen's mother. But now that the body was gone, there was no way to do an autopsy, and there was no key evidence to prove that Chen's mother deliberately destroyed the ladder.

The next day, the technical department completed the inspection of the refrigerator and issued a report.

"The parts inside the refrigerator were soaked with water, causing a short circuit, which completely destroyed the refrigerator."

No fingerprints or blood were detected inside the refrigerator. But they found that one of the parts was wrong.

"This... seems to be a monitor. It can record sounds and transmit them to other devices through the cloud. At the same time, it also records sounds. But its circuit is connected to the refrigerator, and when it short-circuited, it was burned."

"Can it be repaired?"

"Let's try."

After the efforts of the technical department, the monitor was quickly repaired. They played a recent recording:

"Chen Yuankun, I have been kind to you. I trained you as my successor. Why do you want to kill me?" Wang Yonghua said weakly with heavy breathing.

"Because I'm not Chen Yuankun yet. After you die, I can be Chen Yuankun forever." Another person's voice was very proud.

"You are not Chen Yuankun? Who are you?"

"You are going to die soon, I will let you die knowingly. My name is Ding Zhuangzhuang, I slept with your wife, oh, I also slept with Sun Xiaoning and didn't want her anymore... The low-level trash you despise the most now controls your fate."

"Please, don't kill me... Don't kill me!"

The voice suddenly stopped, and after a long time, a voice said: "I almost forgot, there is a monitor here!"

The recording stopped abruptly. It should be that Ding Zhuangzhuang poured water into the refrigerator, causing a short circuit, and the monitor stopped recording.

The technicians tracked the terminal device based on the monitor, which was a laptop. After further verification, the computer was the laptop that Ding Zhuangzhuang used for work.

They got Ding Zhuangzhuang's laptop, and he had deleted all the recordings long ago, but the technical department restored his browser history and found the platform and account where he received the recordings.

The recordings are stored in the cloud, and they can be downloaded again as long as they log in to the account.

The account usage records showed that Ding Zhuangzhuang had been monitoring Sun Xiaoning and Wang Yonghua since three months ago. There were many recordings and they were very complicated. Fang Rui and his friends listened to a few of them at random.

One of the recordings was from half a year ago. In it, Sun Xiaoning and Wang Yonghua were actually plotting to find someone to murder Li Meijia.

Xiao Zhang wondered, "Why did Ding Zhuangzhuang kill people? It wasn't for Li Meijia, was it? But he doesn't look like a love-minded person."

Xiao Wang said excitedly, "Why don't we talk to him and find out?"
