Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 703 Lu Chuan’s bold guess

Lu Chuan had already stood up and walked to the projector screen.

"And we conducted identification and analysis on these fingerprints and found that some belonged to the deceased Wang Chuanzhi himself, his wife and son, and some people from Wang Chuanzhi's company also had fingerprints left on them."

"Fingerprints are superimposed, and the most common place is the right rear door. We extracted seven fingerprints."

"However, we did not extract any fingerprints on the passenger door handle and trunk lock."

"What does this mean?"

The people present were all veteran detectives, and they still didn't understand what Lu Chuan meant.

There are 4 door handles in total. Fingerprints were found on the driver's door handle and the two rear door handles.

This shows that the vehicle has not been cleaned in a short period of time, and when multiple people get on and off the vehicle, when the door is pulled, fingerprints will naturally be left on the door handle.

When inspecting the vehicle involved in the case, if fingerprints need to be extracted, the steering wheel, door handles, armrests, etc. are all important parts for fingerprint extraction.

Why erase it deliberately?

"Killing for money?"

Zhang Hui shook his head affirmatively: "If the other party is really after money, and he knows that Wang Chuanzhi will put the money in the glove box, then just break the glass window when the other party is not around and just take out the money."

"Although we did not collect the fingerprints of the suspected suspect at the scene, the murderer touched the passenger door handle and the trunk lock. Why?"

"The passenger seat was occupied by the deceased Zhang Cuilian. When we found her body, there was no seat belt on her body, which means that the car probably did not drive past her after she got in."

"Compared to murder, robbery or theft is definitely a much smaller crime."

This shows that someone deliberately erased the fingerprints in these two locations.

Who wiped it off?

Someone raised doubts.

"Glovebox?!"

What does the co-pilot have?
Except for the victim...

Zhang Hui suddenly shouted, and everyone reacted.

Lu Chuan looked at Zhang Hui and nodded: "After thinking about the glove box, we have checked it and there is no cash in it."

"But why did the murderer open the passenger door?"

"The current investigation has carried out a careful inspection of the inside of the car, and there is no cash anywhere."

"By the way, when I asked Wang Chuanzhi's wife this afternoon, she said that Wang Chuanzhi had the habit of putting cash in the car..."

However, no fingerprints were found on the passenger door handle and trunk lock.

Lu Chuan flipped the projection and continued to report on the findings of the current survey.

In addition to the vanity mirror on the forehead, the co-pilot's position is the glove box below.

It goes without saying that it must be the murderer.

"wrong!"

"What's more, the murderer faked carbon monoxide poisoning at the scene. Wasn't it just to confuse our eyes and make us think that the two died in an accident?"

"I can't say that there is absolutely no possibility of murder for money, but I think the possibility is extremely small."

Lu Chuan nodded: "I agree with Zhang Hui's judgment."

"The main reason was what was found in the trunk."

Lu Chuan switched the projection, and what appeared in front of everyone was a photo of the interior of the vehicle trunk.

"Judging from the situation at the scene, the murderer opened the passenger door and also opened the trunk."

This can basically be confirmed at present, because the fingerprints in these two places have been erased, indicating that the murderer left traces on them and cleaned them.

"Look, there are three bottles of Maotai, two bottles of Wuliangye, and two strips of Zhonghua Cigarettes in the trunk."

"If the murderer is really here for money, there is no reason not to take away the valuable tobacco and alcohol after opening the trunk." Three bottles of Maotai, two bottles of Wuliangye, and two strips of Chinese cigarettes are worth a lot of money, totaling tens of thousands. Dollars.

If the murderer really came here for money, then it really doesn't make sense to leave so many valuable things without taking them.

"But if he wasn't here for money and he didn't take anything valuable in the trunk, why would the other party open the trunk?"

Some people continued to ask questions.

Many people also nodded.

This is true.

The murderer was not after money, but took cash from the passenger glove box.

The murderer wanted money, but did not take the cigarettes or alcohol inside after opening the trunk.

The question is, why did the murderer open the trunk?

This is a good question.

After Lu Chuan discovered this situation, he studied it with several people in the current survey office for a whole night.

"We don't know exactly why the murderer opened the trunk."

"After careful inspection of the vehicle, the current survey office came up with several hypotheses."

"First of all, the murderer opened the trunk. It couldn't have been for no reason. He must have performed some kind of operation, such as taking things and putting things away."

"It's just that we don't know what he took away or what he added to it."

"The current investigation found something here, which may be related to the murderer's behavior of opening the trunk."

Lu Chuan switched the projection again, and what appeared on it was a photo on the back seat of the vehicle.

"We found this mark in the middle of the back seat of the vehicle, where the rear armrest is."

This location is very hidden, and is a passage that can lead to the trunk after the rear center seat is opened.

There are clear scratches on it.

"We found very clear scratches on the edge of the channel, and the scratches were very short and very fresh."

"We made a bold assumption here."

"It is a certain fact that the two deceased died of carbon monoxide poisoning, but through testing, it has been determined that the gas that caused the death of the deceased did not come from car exhaust."

"So, where did the gas that the murderer used to kill the two victims come from?"

Lu Chuan pointed to the back seat: "We suspect that the murderer probably hid the gas generating device in the trunk and then released the gas into the car through this channel."

"The reason why the murderer opened the trunk was to take away the gas-generating device after the crime was completed."

This guess...

Quite interesting.

"Is there any evidence?"

Qin Yong also found this speculation quite interesting, so he immediately asked for evidence.

Unfortunately, Lu Chuan quickly shook his head.

"The current survey office made such a guess mainly based on two reasons."

"First, the carbon monoxide poisoning gas of the deceased did not come from car exhaust, so where was the source of the gas?"

"Second, the murderer placed this device that generates carbon monoxide gas in Wang Chuanzhi's car. It must be relatively secretive. It can be easily discovered if it is placed in other locations."

"So if you put it in the trunk, the gas can be secretly released into the cabin through the hole in the middle of the rear seat."

"As for the evidence, we can only say that the scratches we found on the holes were probably left by the murderer, so we have such a guess."
