Serious Crime Unit 1

Chapter 1118 Greed (11)
Lu Yingying came to the door of Jiang Yiming's office and knocked gently on the wooden door, but there was no reply from Jiang Yiming. She felt a little strange. She saw him walking into the office just now. Why didn't he speak?Lu Yingying held the round handle of the door lock and twisted it gently. When she found that the door was unlocked, she pushed the door open and saw Jiang Yiming asleep on the desk.

She wanted to exit and let Jiang Yiming sleep for an hour before going in, because when there was a case, everyone often worked overtime, sometimes staying up all night, and she often leaned on the executive chair and took a nap.As soon as she turned around, she heard Jiang Yiming say: "Yingying, have you found any new clues?"

"Captain Jiang, it turns out you are pretending to be asleep..." She turned around and said, "Why don't you squint a little longer and I'll come back later."

"No, I was not taking a nap, but I closed my eyes and was meditating. I was so absorbed that I didn't hear your knock on the door. This problem needs to be corrected. If you are a murderer, sneak into my office quietly and attack me. , wouldn’t it be too late for me to resist?”

"Our criminal police team is heavily guarded. You have to go through security checks when you come in. You can't bring in guns, knives, explosives, poisons... How can we let gangsters come in to commit murder? We found a suspect in the surveillance video of Lotus Lane. His height The weight and weight are similar to the shoe prints left at the scene. Take a look at the surveillance video." She walked to Jiang Yiming, opened her laptop, clicked on the player, and let him watch the surveillance video.

The video shows: At 2021:7:20 on July 00, 40, a tall, thin man wearing a mask walked into the surveillance video. He was wearing a T-shirt on his upper body and jeans on his lower body. He walked hurriedly past the screen and walked toward Walk towards No. 30, Lianhua Lane.He returned at 11:00:55 and walked towards the street. When he returned, he looked nervous and looked left and right, as if he was afraid of people chasing him.

"This person is very suspicious. Unfortunately, the surveillance video is in black and white. If it were in color, it would be possible to see if there was blood on his clothes. Where did he go after that?" Jiang Yiming asked excitedly.

"We haven't had time to check his whereabouts. If he is the murderer and hides in the blind spot of the surveillance, it will be difficult to find him if he disguises himself."

"Do you think he will hide in the surveillance blind spot?"

"If I were the murderer, I would definitely find a way to evade police video surveillance. For example, after hiding in the blind spot of the surveillance camera and then walking out in disguise, we would not be able to find him through the surveillance video."

"I think you need to continue to work hard to find him through surveillance video. We will also visit the residents living in Lotus Lane. Someone should have seen him at that time."

"Okay, I will lead the visual reconnaissance team to continue to search for his whereabouts, but this will take time. Unfortunately, he is wearing a large mask and a peaked cap, and the lights in Lotus Lane are dim and the picture is unclear. It is impossible to restore his face. Otherwise, you can post a reward notice online and find him through the power of citizens."

"If you continue to pursue the investigation, it is very likely that he was exposed to a brightly lit place. If so, it should be possible to use technical means to restore his appearance, right?"

"It should be possible. I think security monitors and traffic monitors are too high to install. It would be best if they were installed 3 meters above the ground."

"It is easy to be destroyed by people and vehicles at 3 meters above the ground. There are standard heights for installing monitors across the country... This suspect should be a friend of Jiang Nancong. Otherwise, Jiang Nancong would not have opened the door on the first floor and the living room on the scene. The door let him in, can you find him in his mobile phone address book?"

"Jiang Nancong is indeed an IT engineer. He uses the latest Samsung mobile phone, which is unlocked with the iris. The human eye structure is composed of sclera, iris, pupil, retina and other parts. The iris is located between the black pupil and the white sclera. The ring-shaped part. It contains many intertwined spots, filaments, crowns, stripes, crypts and other detailed features. There are no two irises in the world that are exactly the same. So it cannot be cracked." Lu Yingying said regretfully.

"Then it means there may be many secrets hidden in his mobile phone."

"That's what I thought too. Maybe he was killed because of the secrets in his cell phone."

"But the murderer didn't take away his cell phone."

"Because no one can unlock it except Jiang Nancong, the murderer doesn't have to take the phone away to prevent us from locating it."

"This further proves that the murderer is Jiang Nancong's friend. Otherwise, we wouldn't know that his phone was unlocked with iris."

"Yes." Lu Yingying nodded and left.

Jiang Yiming and Zhou Ting went to Jiangbei District Mobile Company to check Jiang Nancong's mobile phone call records. Manager Cao Wang of the sales department had dealt with Jiang Yiming many times and were already old friends. Therefore, Cao Wang quickly reported Jiang Nancong's call records in the past six months. All incoming call records are printed.

Jiang Yiming carefully checked the call records and found that Jiang Nancong only talked to 28 people on the phone in half a year. No one talked to him on the phone on the day of the crime, but he had a total of three phone calls on July 7, the day before the crime.

The first call was made by Fan Shuyang, and the call time was 19:18:12 on the 20th, lasting 58 seconds; the second call was made by a stranger, and the call lasted only 21 seconds. Jiang Yiming thought it might be a sales call or Of course, the scam call cannot be ruled out as being made by the murderer, because the murderer knows that the police will look for suspects through call records, so there is no need to call with a real name.This call came in at 18:30:20.

The last call was made by Jiang Nancong to Huang Taohe. They should be friends or colleagues and talk frequently. The call time was at 19:23:55 on the 30th, and the call duration was one and a half minutes. This call was a bit suspicious because it was already night It was very late, and they were still talking on the phone, so it was a bit strange.

A copy of Huang Taohe's ID card was left with the mobile company. He was born on October 1990, 10, and lived in Room 15, Building 13, Lanhai Community, No. 12 Back Street, Jiangdong District.Jiang Yiming thought he looked familiar, as if he had seen him somewhere, but he couldn't remember.

Jiang Yiming's memory is very good, especially in face recognition. For example, if he met a person 10 years ago, if he met him on the street 10 years later, Jiang Yiming would be able to recognize him at a glance, so he was born He was a criminal police officer, but for some reason, he couldn't remember where he had seen Huang Taohe. This made him a little frustrated. Could it be that he was getting old?

He felt that he should go to Huang Taohe and ask him why Jiang Nancong called him at that time.Will Jiang Nancong feel that his life is threatened and call Huang Taohe for help?Or tell Huang Taohe who wants to kill him?And Huang Taohe was worried that the murderer would retaliate against him, so he didn't dare to call the police?If these assumptions are true, Huang Taohe is very likely to know who the murderer is.

Jiang Yiming told Zhou Ting his thoughts, and Zhou Ting agreed with him.Although Jiang Yiming is a captain, he likes to discuss issues with his subordinates. No matter how big or small the issue is, he always seeks their opinions. Because everyone has different life experiences, family backgrounds, and knowledge, they have different perspectives and ideas when looking at problems.

Zhou Ting drove towards Huang Taohe's house.Jiang Yiming called Huang Taohe in the car, but couldn't get through. Jiang Yiming was stunned for a moment: Huang Taohe wouldn't be silenced, right?Thinking of this, Jiang Yiming called the property management company of Lanhai Community and found out that the names of Huang Taohe's parents were Huang Jun and Huang Jun's mobile phone number.

Jiang Yiming dialed Huang Jun's mobile phone and got through immediately. Jiang Yiming said: "Hello, Mr. Huang, I am Jiang Yiming from the Municipal Bureau's Criminal Police Team. Are you at home? We want to know the situation from you."

"Oh, it's Captain Jiang, hello! Hello! Today is Sunday. I didn't expect you guys to work on the weekend. I happen to be at home. Do you want me to go to your criminal police team, or do you want to come to my house?" he asked enthusiastically.

"We are on the way to your home. Please wait for us at home. Thank you for your cooperation!" After Jiang Yiming finished speaking, he hung up the phone.

A quarter of an hour later, they appeared at the door of Huang Jun's house. Huang Jun heard someone calling him outside the door and immediately came out to open the door. After seeing them, he invited them into the house for tea, sat down and talked slowly.Huang Jun once worked at the Jiangdong District Procuratorate when he was young. He was later dismissed from public office because he lost key evidence, allowing the suspect to escape legal sanctions.In fact, the key evidence was stolen by a thief. He should not be fired from his job. However, as the person in charge, he should lock the evidence in a safe instead of putting it in a desk drawer to allow thieves to take advantage of it.

After Huang Jun was fired from public office, he went to Shanghai to set up a garment factory. As a result, it grew bigger and bigger. Now the trade volume of exporting clothes reaches hundreds of millions yuan a year. In addition to paying taxes, he can earn more than 500 million yuan a year. Therefore, Huang Jun The Jun family can live in the Blue Ocean Community, which has a sea view. Each apartment above the 10th floor costs tens of millions of yuan.After the two parties sat down, Jiang Yiming said straight to the point: "Mr. Huang, actually we are not here to see you, but to see your son Huang Taohe. Do you know where he is now?"

"Oh, did my son make a mistake?" When he heard this, he felt bad, and his heart suddenly rose. The captain of the criminal police of the city bureau came to find his son. It was definitely not an ordinary mistake, at least it was a criminal case.

"No, because Huang Taohe had an interaction with a deceased person. No, he should be said to be a good friend, so we have to ask him to assist in the investigation." Jiang Yiming tried his best to calm his emotions, so he spoke softly.

"Because he likes tinkering with computers and often stays up late, so he is sleeping at home at this time and I can wake him up."

"Okay, please wake him up." Jiang Yiming felt that Huang Taohe and Jiang Nancong were from the same place. Not only did they have the same hobbies, but they also had the same schedule. No wonder Jiang Nancong would call him late at night.

After a while, Huang Taohe rubbed his eyes and walked up to Jiang Yiming. Jiang Yiming looked at it and was stunned for a moment. It turned out that he was the person he saw in the surveillance video of Lianhua Lane. His gait, body shape, and height were all very similar. He was very similar. May be the murderer of Jiang Nancong!
"Huang Taohe, we are from the criminal police team of the city bureau. Do you know Jiang Nancong?"

"I know... I know... he is my friend... no, he should be a colleague..." As soon as he heard that they were from the criminal police team, he immediately became nervous. He was originally sleepy, but suddenly he woke up, straightened his back, and stared at Jiang Yiming. , seemed to be seriously thinking about how to deal with them.

"Why did Jiang Nancong call you late at night on July 7th?"

"It's nothing. We originally made an appointment to go for supper together, but he said he was in an emergency and couldn't go with me to eat. That's all we talked about... and a few words about Internet knowledge." He was still watching. Looking at Jiang Yiming, hoping that Jiang Yiming would believe him.

"You don't need to draft a lie. Where were you from 7:20 to 0:1 on July [-]? What were you doing?" Jiang Yiming's expression became serious. He originally thought that Huang Taohe was just a clue, but he didn't expect to directly encounter the suspect. People, it’s true: “You can’t find anything even if you wear iron shoes, but it takes no effort to get there.”

"I was surfing the Internet at home...really, I didn't lie..." His face turned red, as if he was drunk.

"Your father said you were an IT technician. I didn't expect you to be so ignorant. Don't you know about the Skynet Project? The Skynet Project is a monitor installed by the Ministry of Public Security all over the country, covering almost every corner where people live. Similarly, Lotus Monitors are also installed in the lane, and you passed the monitor at No. 2021 Lianhua Lane at 7:20:00 on July 40, 30, and returned at 109:00:55."

"I didn't go... you must have misunderstood... maybe it's someone who looks very similar to me..."

"I'm sorry, we don't judge who is you by the face, but by the height, weight and gait. When you walk from the bedroom to the living room and come to me, I will use these three conditions to lock you. Suspect in surveillance video.”

"But China has a population of 14 billion, and there are at least 1 million people with the same height and weight as me. How can you tell that person is me?" He asked loudly, obviously covering up his inner fear.

"People's height and weight will be the same, but their gait, like fingerprints, is exclusive and unique. Your gait is similar to the suspect in the surveillance video. Please take a look." Jiang Yiming took out his mobile phone. Open the surveillance video from that time and show it to him.

He glared at Jiang Yiming, then looked at the surveillance video. He was not surprised. After watching it, he said, "Even if the person in the surveillance video is me, it doesn't mean anything."

"It can't explain anything. It can only prove that you went to Lotus Lane at that time. Therefore, in order to rule out your murder suspicion, we must take you back to the criminal police team to make it clear whether you were looking for Jiang Nancong at that time."

"Why go to the criminal police team? Can't you say no here?" he asked with a frown.

"If you are willing to cooperate with us, you can say it here. We will first collect your fingerprints, and secondly, check all the shoes you have worn. Do you agree?"

"It doesn't matter if I don't agree... I know you have many ways to make a civilian bear an unjust case. Hugjilt and Nie Shubin were unjustly killed by the police."

"I have been a police officer for 16 years and I have never handled an unjust case. Don't worry, we speak with evidence and will never use torture to extract confessions!" Jiang Yiming asked Zhou Ting to collect his fingerprints.Zhou Ting took out the fingerprint collector from his bag, pressed all 10 of his fingers on the collection area for collection, and quickly collected his fingerprints.

Then he sent the fingerprints to Wu Jiang and asked him to input them into the computer and compare them with the fingerprints collected from the dagger at the crime scene.Comparison results: Huang Taohe’s index and middle fingers are exactly the same as those at the scene, and it can be determined that he is the murderer.

"You must come with us this time. You are suspected of murder!" Jiang Yiming didn't allow him to tell the difference and grabbed his left arm. Zhou Ting grabbed his right arm and took him out.

He didn't resist, knowing that resistance was futile, so he shouted loudly into the house: "Dad, I didn't kill anyone, you must come to save me..." He cried while talking, and Huang Jun ran out of the house, Stop Jiang Yiming and ask Jiang Yiming why he took his son away?
Jiang Yiming briefly explained the situation. Upon hearing this, Huang Jun's face instantly turned white, his feet limp on the ground, and he murmured: "Son, you don't have to be afraid. As long as you don't kill anyone, even if your father goes bankrupt, he will not be afraid." Gotta rescue you."

Jiang Yiming escorted Huang Taohe to the interrogation room, and then went to Fang Lihua's office to apply for a search of Huang Taohe's home, because when Huang Taohe killed someone, Jiang Nancong's blood would definitely splash on his clothes or shoes.After hearing this, Fang Lihua agreed and wrote him a search warrant.

After Jiang Yiming obtained the search warrant, he took Wu Jiang, Xiao Ke and Zhou Ting to search Huang Taohe's house, and brought all his shoes and clothes back to the criminal police team, and also brought his dedicated laptop back to the team.Wu Jiang and Xiao Ke inspected Huang Taohe's 12 pairs of shoes and found that the pattern on the sole of one pair of Adidas shoes was exactly the same as the shoe prints extracted at the scene.

Lu Yingying checked Huang Taohe's computer and found no trace of illegality except that he fell in love with pornographic websites.

Luo Jin sprayed all Huang Taohe's clothes with occult blood blue light reagent, and found an occult blood reaction on a blue Paul brand T-shirt.Although the clothes have been washed, the occult blood blue light reagent can still detect blood stains.

Occult blood blue light reagents are mainly used to detect the presence of traces of occult blood in cleaned crime scenes and to locate blood traces.This new chemical product is based on the luminol formula, adding patented additives, and after special processing, it improves the sensitivity of occult blood display.It can detect blood stains diluted to 1/1000 without affecting subsequent DNA determination work at all.

Luo Jin extracted the blood stains and used them to make DNA. After the results came out, they compared them with Jiang Nancong's DNA. The results were exactly the same. The shoe prints, fingerprints, and blood stains on clothes were enough evidence to convict Huang Taohe, even if Even zero confession will not affect the conviction.

Unexpectedly, the murderer was caught so quickly and everyone was happy.
