Evidence hunting forensic 4 unsolved case code

Not long after Lin Dong and the others returned to the office, Guo Haoxuan also came up.Obviously he didn't understand why Lu Yuanqiao suddenly changed his face, and went into the room to ask Wen Yingjie if he had violated the regulations by going to the forensic office. There was a police officer from the serious crime team there who seemed to have a strong opinion of him.But Wen Yingjie didn't know how Guo Haoxuan had offended Lu Yuanqiao, so he just told him to stay in the house obediently, and don't run around when he has nothing to do, as it won't make him look good if he disturbs people's work.

Guo Haoxuan was obedient, he was told to stay in the house obediently, so he obediently stayed there.Turn on the computer, connect to the hotspot of the mobile phone, plug in the earphones, and continue to use the computer to compose music.He Lan had learned the violin and watched him play with the music score. He leaned over to listen to it, and quickly gave him a thumbs up.

Yue Lin also wanted to join in the fun, but Lin Dong coughed and pushed him back to the chair, and asked cautiously, "Captain Lin, is there anything I can do?"

"Well, you and Yangzi help me find the landform map of this area around [-]." Lin Dong handed him a note with the address on it, "If the satellite map is hard to find, check the Bureau of Meteorology, Geology, and Water Affairs. Record."

Yue Lin took the note, dragged the swivel chair to Yang Kelin's side, and used his smart little brains to complete the tasks assigned by the leader.Tang Zhexue heard that Lin Dong wanted to check the records of the Water Affairs Bureau, so he turned his head and asked, "Why check the records of the Water Affairs Bureau?"

If you want to see the original appearance of the crime scene, generally speaking, the records of the Geological Bureau are almost enough. Of course, the aerial map of the Meteorological Bureau will be more comprehensive.When the time is closer, it is more convenient to find satellite images.

"Feng Bing's work log has a survey map, and there is a flood discharge channel passing through the village about [-] meters away from the location where the broken arm was found." Lin Dong pointed up the notebook at him, "It should have been filled in when the golf course was built. .”

Tang Zhexue glanced at the simple site survey map drawn in the notebook, and nodded: "Do you suspect that the corpse site is in the flood canal?"

"A dozen police dogs didn't find any blood stains. I guess they were washed away by the water."

"In that case, the other parts would have been discovered long ago."

"Yeah, so..." Lin Dong frowned, lowered his head and continued to look through his notes, "Feng Bing's work log is similar to what's recorded in the file, so there's nothing—"

Suddenly his voice paused, and after a few seconds of silence, he handed the notebook across the table to Tang Zhexue, took out a pen and pointed to a line of records: "Look here, a villager he visited said that someone would blow up a flood in the flood canal." fish."

Frying fish is a serious illegal act. The detonators/tubes and explosives used basically come from informal channels. If you catch them, you will be sentenced.But what does this have to do with Susahai's case?Tang Zhexue was slightly confused.

While he was studying the interview record, Lin Dong had already got up and walked to the whiteboard for case analysis, wiped off the traces left before, drew two circles on the left and right, drew a straight line in the middle, and marked the distance. Draw a parabola on it, and then write the equation in the blank space.

Lin Dong asked: "Yingjie, what is the weight of the severed arm in the autopsy records?"

Wen Yingjie opened the file and replied, "[-] kg."

After getting the data, Lin Dong began to fill in the formula.Tang Zhexue can probably see what he is counting - to find out how much initial velocity the object needs to reach the distance between two points of the parabola.Calculating data is generally a matter of criminal skills, but when Lin Dong took the college entrance examination when he was in the junior class, he got a full score in science and technology, and he had a solid grasp of mathematics, physics and chemistry.

Afterwards, Lin Dong wrote the formulas, even Yang Kelin, whose mind was full of known mathematical formulas, had never seen it before.He asked Lin Dong and was told it was about thermodynamics.This belongs to Lin Dong's former professional field. Before entering the police academy, he was admitted to aerodynamics. It is said that this major used to be called thermodynamics.

The whole room watched with bated breath the calculation process he had written on a whiteboard, and finally came to the conclusion that about [-] to [-] kilograms of earth-made explosives/powders could blow up an [-]-jin arm to a hundred meters away.

Now Tang Zhexue understands what Lin Dong is trying to prove: "Do you think the amputated arm was blown away by the fish bomb?"

Lin Dong put down his pen and turned to look at everyone: "If you think about it this way, only the discovery of the broken arm can explain it. The suspect who planted the explosives couldn't find Su Sahai's blown arm after the accident. Dealing with the remaining part, the penetrating wound on the severed arm was not left by a carnivore, but the fragments of rock that splashed during the explosion penetrated the skin and muscles, and the rough fracture was not caused by human beings, but was broken by an explosion, but It is a pity that no explosive/explosive residue test was done at that time, and my current assumption cannot be verified from a technical level."

Yue Lin raised his hand: "But Team Lin, according to what you said, what a big commotion that was, did no one in the village hear the explosion/explosion?"

Lin Dong lightly shrugged his shoulders: "On the night of return, I remember that fireworks were set off everywhere that night, let alone fried fish, and no one might pay attention to the movement of the mountain."

On the day of national celebration, the common people are keen to set off fireworks to express their joy, after all, there was no ban on the release at that time.Yue Lin didn't remember him anymore. He hadn't been to kindergarten yet when Hong Kong returned to China.

At present, although Lin Dong's inference cannot be demonstrated from the existing evidence, there is a general direction to continue the investigation.It's just that a new problem came up again. In the middle of the night, what kind of water did Su Sahai go to the flood discharge channel when he had nothing to do?Fell in after drinking too much?No, although alcohol was detected in the severed arm, the alcohol content per [-] milliliters of blood is only a dozen milligrams, which is not at all to the level of drunkenness.

Based on past experience in handling cases, Tang Zhexue put forward his own opinion: "Could it be that he hid some valuables in the flood discharge channel and went to fetch them in the dark, only to be blown up by a fish bomber?"

Lin Dong shook his head: "According to the testimony of the villagers, Su Sahai was willing to take the risk to smuggle out of the country because of his poor family. After he came back after getting rich, he wanted to show off all the valuable things on his body. The golden chain and watch, No one can pull it out, so the investigators at the time locked the motive of committing the crime on killing money and ignoring the possibility of accidents."

When the team members saw that the deputy team's proposal was rejected, they all pursed their lips and did not speak, and the room suddenly fell silent.At this time, Guo Haoxuan looked around, raised his hand like Yue Lin asked before, and tentatively said, "Captain Lin, can I have an idea?"

Lin Dong was slightly surprised, but still nodded.

"I think it's possible for Vice-team Tang to pick up things, but they don't necessarily have to be valuable things. Maybe they're time capsules buried in childhood. Oh, maybe it wasn't called that way before." Guo Haoxuan paused for a moment, weighed his words and continued: "My father buried an iron box under a tree in the back of the village when he was a child, and inside it were some of his special treasures, such as foreign paintings, iron soldiers, etc. , Later he took me to the mountain and dug it out, and kept it at home until he was buried together.”

This opinion is worthy of reference. Although no one here has buried the "Time Capsule", it does not mean that Su Sahai has not buried it.If you think about it in this way, his move to go to the flood canal in the middle of the night is also logical-it’s not good for a dignified big boss to go to the ditches to dig the old things he buried when he was a child in broad daylight. So when you have money, you still miss those worthless things.

However, memories are priceless, and this kind of emotion can only be experienced by people who have been away from their homeland for many years.Lin Dong could understand. Lin Yang had said before that when he returned to this city after leaving his hometown for more than ten years, he could hardly find anything familiar.

Glancing at his watch, Lin Dong began to assign tasks: "Okay, first search according to the existing thinking, Yangzi and Yue Lin, look for the old people in the village in the system, and after you find them, Erji, you take them to ask them one by one. , Ask everyone who has fried fish, Yingjie, contact Su Sahai’s family and make an appointment to visit, Lan Lan, write a report on the resumption of the investigation of the case, and report to the Fang Bureau tomorrow morning.”

Everyone responded separately and acted separately.While they were busy, there was a knock on the office door.Gao Ren came and asked Guo Haoxuan to go out and talk.Seeing his aggrieved expression, Guo Haoxuan hurriedly took off his earphones and got up to leave the house.

After a while, Tang Zhe went out to smoke, and just pushed the door of the safe passage open, when he heard Gao Ren's voice from the corner of the meeting room on the fifth floor below: "I don't think you are annoying, let alone I don't like the songs you write, don't get me wrong, it's just that my situation is a bit special, that...you treat me so well, I...my partner is not happy."

Guo Haoxuan's voice sounded inexplicable: "Your partner still cares about your making friends? I'm not a woman."

"No, no, he doesn't care if I make friends or not, it's... yes..." Gao Ren murmured, "I, I'm dating him...he...he...just that...you just met The one on..."

There was silence at the bottom, Tang Zhexue pushed on the door with his hands, retreating or advancing, he could only poke there and listen to gossip.

After a while, Guo Haoxuan suddenly said, "Is Police Officer Lu your partner?"

Gao Ren didn't move, judging from Tang Zhexue's understanding of the other party, the current bun skin must be kneaded out of flour and red dragon fruit.

"That's it, then I really...uh, what I said was a little too much." Guo Haoxuan was full of apologies, "Well...how about I explain it to him, so that he doesn't misunderstand."

"No, no, I've already told him, that is...you don't write songs for me anymore, he will get into trouble if he finds out."

"I understand, my lover is someone else's muse, and this kind of thing will feel awkward to anyone."

"Huh? Myu...Muse...haha, it's not that...so exaggerated..."

Tang Zhexue felt happy after hearing this, and thought that the size of this muse must be a little bigger.

Then I heard Guo Haoxuan's seriousness: "No exaggeration, really, Brother Ren, I haven't written a new song for more than a year, but after seeing you today, I immediately got inspiration, I feel that I can release two new albums in a row. "

"Huh? Do I look like a stave? Hahahaha——"

It seemed that he was so praised that he didn't know how to respond, so Gao Ren could only laugh.However, in the relaxed atmosphere of the conversation, there was a "squeak" sound of the door, and then Lu Yuanqiao asked in an unhappy tone: "What are you talking about so happy, I heard your laughter in the conference room .”

——Yes, this time is good, let's catch the action.

After imagining Lu Yuanqiao's heartbroken expression, Tang Zhexue withdrew his hand on the door with a smile.Just as I was about to go up two floors to find a quiet place to smoke a cigarette, my phone rang suddenly, and Lin Dong called.He immediately returned to the office, and the other party told him that he had just received news from Zhuhai that Li Pengfa had been found, and Bureau Mao asked him to go there as soon as possible.

"Shall we go together?" Upon hearing that he was going on a business trip, Tang Zhexue's first reaction was that the two cubs at home were going to be sent to foster care again.

"No, you stay here to watch Su Sahai's case, I'll take Yingjie there."

"Does anyone want to bring it back?"

"I can't bring it back. He is suspected of smuggling cigarettes and has been arrested by Zhuhai."

Tang Zhexue couldn't help frowning: "Then you have to pay attention to his nonsense on the issue of black and yellow hair and tiger teeth in order to reduce his sentence for meritorious service."

"Yeah, you have to carefully judge his testimony." As he spoke, Lin Dong leaned forward and moved closer to Tang Zhexue, sniffling, "Did you go to smoke just now?"

"Hey, I'm just here to listen to people chatting."

"Gao Ren?"

"Ah? Ah... No, no... It's the leader, the leader."

Faintly feeling that small antennas were erected on the heads of the team members, Tang Zhexue decided it was better not to be that gossip spreader.
