Romon already knew it was a murder. The deformed steering wheel, the dents around the interior of the car, and the smell of nitroglycerin in the air are all evidence. But this evidence is still not convincing, how did the criminal kill Zhao Zhicheng, and what motive did he have? Romon also needs some evidence.

Romon continued to look for suspicious spots, and the other police officers focused on the deceased's relics. For example, charred mobile phones, credit cards, watches, and various items in the car.

The seat cushion of the car was burned to the ground, but there was a small piece of unburned sponge on the seat cushion that attracted Romong's attention, the surface of the sponge was blackened, only four centimeters in size, this charred material had no value, and the police did not treat the sponge as a suspicious object.

Luo Meng felt a little strange, curiously took the sponge, pinched it gently, and some water droplets fell down in the sponge, and the sponge was filled with water, no wonder it was not burned out.

"This sponge is inside the seat cushion of the car, and the seat cushion of the car is covered with skin, how can it get water?

Romon carefully peeled off the blackened part of the sponge, revealing the yellow sponge.

In the sponge, a crack caught Romong's attention, and this crack was neatly broken, apparently cut with a blade. Obviously, this criminal element cut it, and Zhao Zhicheng will not be bored enough to cut his own cushion with a knife.

Romon fell into confusion for a moment: "Why did the criminal cut the seat cushion?" Could it be that he did something on Zhao Zhicheng's seat cushion? ”

After taking a bunch of photos of the sponge, Romon gently peeled off the sponge, and a piece of ice the size of a needle tip that had not yet completely melted caught Romong's attention, and the camera snapped wildly.

"Why would a criminal put ice cubes in the sponge of the seat cushion?" Another mystery confuses Romong.

Putting away the sponge block, Romon continued to look for evidence.

On the brake side of the car, another object caught Rommon's attention, and that thing was actually a needle. There were still some remnants of the blood stains on the tip of the needle that had been burned dry.

This suspicious rusty needle made Romon concentrate.

"How can there be needles in a car? Zhao Zhicheng is a big man, a famous rich man, time is very precious to him, he will never be bored to have nothing to rust and play embroidery. This needle is definitely not a remnant of Zhao Zhicheng. ”

"If this needle is not a remnant of Zhao Zhicheng, there are only two possibilities, one, it may be left by the criminal. Second, it is possible that Zhao Zhicheng's family accidentally left it in the car. No, the second hypothesis is not true, and Zhao Zhicheng's family cannot be bored enough to play with needles. This is definitely left by the criminals. ”

Romon put on his gloves and carefully clamped the needle with tweezers and put it in a plastic bag, adding another piece of physical evidence.

Romon continued to search, but there were no other objects, most of the things had been collected by other police officers as evidence.

"It's murder, 100 percent murder. Sponges, ice cubes, sweet nitrate oil, needles, if I am a criminal and I want to kill Zhao Zhicheng, what should I do? Luo Meng used these evidences as a tool to kill people, and substituted himself as a criminal, imagining how he used these things to kill Zhao Zhicheng.

In less than a minute, Luo Meng smiled, about how the criminal killed Zhao Zhicheng, Luo Meng already knew that as a genius criminal, in terms of killing, Luo Meng had many ways, this criminal was completely an axe, and he met Luo Meng, the ancestor of the criminal.

But who are the criminals? What was his motive for killing? Romon doesn't know yet.

But Romon can already be sure of something, this criminal is a high-IQ criminal who is careful and has some knowledge of chemistry. Because Romon had already judged from the smell in the air that these 'nitroglycerin' bombs were different from those used by the military, these liquid bombs were made by themselves.

In fact, it is not difficult to make nitroglycerin bombs, some soap, shampoo, and some chemicals can make powerful liquid bombs, but this requires some knowledge. Because the principle of making this kind of bomb is not very difficult, but in the real manufacturing process, there is still a certain degree of difficulty, if you are not careful, the loud noise caused by the explosion can alarm many people, or hurt yourself.

In addition, this criminal is very familiar with Zhao Zhicheng, and it cannot be ruled out that some close people around Zhao Zhicheng have contact with this criminal. There are actually some difficulties in unknowingly placing the liquid bomb on Zhao Zhicheng's car. And to calculate accurately, Zhao Zhicheng had an accident on the overpass, and killed Zhao Zhicheng seamlessly, this person is definitely not simple.

Romon fell into deep thought. In the distance, several police officers, who had been away for an hour and a half, had already returned to the scene.

After Wang Lin asked the police around him to analyze the physical evidence, he began to ask several police officers about the investigation.

"Xiao Li, how about the call records I asked you to check in the mobile department."

"Captain, this is Zhao Zhicheng's call record for the last month, you can take a look." Xiao Li handed over a stack of printed call records to Wang Lin.

The policeman surnamed Li continued: "Captain, according to my investigation, Zhao Zhicheng is rushing to celebrate the birth of his youngest daughter today, and when he left Zhao's house, he talked to a woman for five minutes. ”

"Hmm."

"Xiao Zhang, I asked you to investigate Zhao Zhicheng's medical records, is the investigation good?"

"Back to Captain, this is Zhao Zhicheng's medical record, from the medical record last year, Zhao Zhicheng was guilty of a spasmodic disease, and sometimes he had cramps."

Wang Lin nodded: "It seems that this is really an accident, when Zhao Zhicheng drove the car at the turn of the overpass, he may have had a spasmodic attack, resulting in cramps, and he did not grasp the steering wheel of the car, and after skidding, he hit the guardrail, and the car body was across the overpass, and the traffic behind him could not stop the car, and hit the fuel tank, resulting in a big explosion, and Mr. Zhao Zhicheng died in this accident." ”

"Captain, that's a possibility."

"Xiao Wang, I asked you to go to the traffic department to investigate the status of Zhao Zhicheng's Mercedes-Benz S600 and what the situation is."

"Report to the captain, Zhao Zhicheng has twelve years of driving experience, there has not been a violation in the last three years, his driving skills should be passed, all rich people are afraid of death, this car has only been bought back for a year and a half, and it has not been repaired. The car is in good condition. He washed the car once today and here's the invoice. ”

"Well, it seems, it can be ruled out that he killed. There is no problem with the car, it is impossible for someone to do it secretly. ”

"Xiao Huang, I asked you to investigate the owner of Zhao Zhicheng's car in the back, is there a problem?"

"Captain Hui, the owner of the car is from Jiangnan City, engaged in transportation, a big old man, and he can't even speak Mandarin completely. Through contact with the local police, the owner of the car is an honest man, engaged in transportation, in his fifties, with a good family background, and should have no motive to commit the crime. ”

"Well, well done. The owner of the car had to be interrogated carefully. ”

"Yes, Captain."

"Xiao Zheng, the forensic doctor at the hospital has identified the cause of Zhao Zhicheng's death, is there anything abnormal?"

"Back to the director, Zhao Zhicheng's buttocks were seriously injured, his bone pelvis was completely cracked, and he was seriously burned all over the body, and there were traces of injuries from the impact of the explosion on Zhou's body, and there were many pieces of broken glass in his body. The forensic examination, Mr. Zhao Zhicheng, should have died from the explosion and impact. ”

Wang Lin sighed lightly: "Judging from these evidences, Mr. Zhao Zhicheng died accidentally. This case was decided. Let's report to the above, and then report to the Zhao family. ”

"Yes, Captain."

Luo Meng shook his head secretly: "Damn, this kind of pig's head can also be the captain, this is obviously murder, you can't see it so simple." The police of the 21st century are really mentally retarded. ”

Luo Meng had the heart to go up and tell Wang Lin that this was a murder, but the pig-headed captain would definitely not believe him. He wanted to find an opportunity to kick himself out of the police force, and now was not the time to tell the truth.

Wang Lin is very relaxed, the faster this case is solved, the more the efficiency of the police can be shown, and all evidence proves that Zhao Zhicheng died in a traffic accident because of a spasmodic attack. Solve this case, what's the matter, the police force has to give themselves a credit.

In less than ten hours, he solved this big case that shocked Tiannan City, and his squadron leader made a meritorious record, and it was much easier to climb to the position of captain in the future.

"Let's go back to the police station, everyone writes an investigation report, and I am ready to close the case like this and hand it over to the captain and the director."

"Yes, Captain."

A group of policemen followed Wang Lin and walked towards the police car in the distance.

After groups of media reporters saw Wang Lin and others coming out of the scene, they began to rush over frantically, wanting to interview the police about their views on the case.

Wang Lin straightened his police uniform, straightened his spine, and waved to reporters with a smile, apparently wanting to use the media to show his face, show his ability, gain some fame, and accumulate some political capital.
