Ye Qian heard my compliment, raised her eyebrows at me, and continued proudly: "After we retrieved Zhao Junxin's phone bill, we found that he had dialed an unfamiliar number during the time of the crime. He dialed this number. Four times, no one answered.¡±
"Then we found the information about this number. It was a home card without real-name registration, and the activation time was one week before the explosion. By checking the call records of this number, we found that only Zhao Junxin had dialed this number, and They are all missed calls, which means that every time Zhao Junxin calls this phone number, the owner of the phone does not answer."
"We were worried that he had accomplices, so we had to find out who purchased the home card. We checked the communication company's home card distribution release, because there is a serial number behind each home card. Later, with the cooperation of the communication company, Next, we finally discovered that this card was sold at the main store of our city¡¯s pedestrian street.¡±
"Fortunately, there are surveillance cameras everywhere in this store, and we found out through the surveillance equipment that Zhao Junxin purchased the phone card himself. Now the question arises, why did he call his own mobile phone on the day of the incident? And he was beaten four times at once?" Ye Qian tilted her head and looked at Brother Ming and asked.
Brother Ming was speechless and extinguished the cigarette in his hand. After a moment of silence, he suddenly raised his head and said to Lao Xian, "Guo Xian, go and get me the mobile phone you picked up from the scene."
Lao Xian nodded and walked towards the laboratory. Not long after, he walked up to Brother Ming carrying an evidence bag.
"Give!"
Brother Ming took it and then tore open the evidence bag.
¡°Perhaps it is because the quality of the phone itself is excellent, or the power of the explosives was not directly released on the phone during the explosion. The damage to this phone does not appear to be too serious.
Brother Ming took out his mobile phone, opened the main board of the mobile phone, and pulled out the intact mobile phone sim card. Then he removed the phone sim card from his mobile phone, replaced it with this one, raised his head and said to Ye Qian: " What¡¯s the home card number?¡±
Ye Qian glanced down at the notebook and quickly replied: "136xxxx6578."
¡°Xiaolong, use your mobile phone to call this number!¡± Brother Ming said to me.
Hearing this, I took out my mobile phone from my pocket and quickly pressed the phone number on Ye Qian¡¯s notebook.
"Tuberose, I sing for you. Tuberose, I think for you." At this time, a piece of Teresa Teng's "Tuberose" came out from Ming Ge's mobile phone.
"What? Is this Home Card inserted into the mobile phone picked up at the scene?" I widened my eyes and was a little surprised when I looked at Brother Ming's mobile phone on the table that was vibrating while playing music.
Brother Ming picked up his mobile phone, pressed the hang-up button, replaced his mobile phone card, and said to us: "Jiao Lei, go and retrieve the location photos of the scene from your computer."
The so-called azimuth photos are photos that reflect all the scenery around the crime scene. It can directly show the azimuth relationship between the central scene and the surrounding environment. Generally, to take such photos, Pang Lei needs to stand on a relatively tall building around the crime scene. on things.
A few minutes later, Pang Lei printed the photo of the direction Brother Ming needed on the projection screen in the conference room.
Brother Ming took a look at the photo and said, "Just now Ye Qian mentioned that she asked Zhao Junxin at the police station. I suddenly remembered something. When I first saw Zhao Junxin in the duty room, the cleaning lady said something. She It is said that there are a lot of pine leaves on his body. From this azimuth photo, we can easily see that there is a pine forest about 300 meters north of the explosion site. By the way, Ye Qian, when did Zhao Junxin call that person? Home card?" When Brother Ming said this, he changed the topic and asked Ye Qian.
After hearing this, Ye Qian quickly took another look at the notebook and replied: "The first call was made at 9:3:15 a.m., and the subsequent three calls were made without pause. They were continuous calls."
Brother Ming nodded after hearing this and said: "The explosion occurred around 9:05. In other words, Zhao Junxin was most likely hiding in the pine forest in the distance to observe the fireworks factory at this time. The specific process of committing the crime It is now very clear. According to my inference, this Zhao Junxin had a motive for committing the crime. He found someone to call the reporting hotline and lured Liu Feng into taking the bait. Then he hid in the woods far away and observed the movement, preparing to wait for an opportunity to commit the crime. When he saw him When Liu Feng walked into the yard, he called his cell phone and detonated the explosive. So the cell phone left at the scene should be the detonation device."
"Is a mobile phone an explosive device?" I asked incredulously.
"Director Leng, do you know that Zhao Junxin??How to ignite explosives with a mobile phone? Ye Qian asked with some surprise.
"I don't know!" Brother Ming said these three words "quickly".
I was still full of confidence, but when I heard this, I suddenly became weak.
¡°It took me a long time to do this, but I¡¯m just happy for nothing.¡± I said with a long sigh.
Brother Ming looked at me, then turned his attention to Fat Lei, and said: "Jiao Lei, Xiaolong, Ye Qian, the three of you go to the Flamingo Internet Cafe now and adjust the surveillance along the surrounding streets. Let¡¯s see what Zhao Junxin did after he came out of the Internet cafe.¡±
"Okay!" The three of us replied in unison.
Flamingo Internet Cafe is located on the north side of a spacious cement road. It is surrounded by shops and has high surveillance coverage. Based on the time points given by Ye Qian, we moved forward one by one.
When the surveillance was extended to the intersection, we found that Zhao Junxin got into a taxi at the intersection, and then we ran non-stop to the traffic police detachment monitoring room to look for the trajectory of the blue Santana taxi with the license plate "Wan dt2993".
Finally, we found that the taxi stopped at the entrance of a chemical reagent store. After Zhao Junxin got out of the car, he quickly walked into the store and then took the taxi back to Luwei Village.
"What did he go to the chemical reagent store to buy?" Ye Qian asked, frowning and staring at the computer screen.
¡°It¡¯s not easy to know what to buy, just go to the store and ask.¡± I recorded the exact time shown on the monitoring device on the display, got up and walked out the door.
Half an hour later, the three of us drove to the chemical reagent store that Zhao Junxin had patronized. The reagent store was not big, covering an area of ??more than 50 square meters at most, and was distributed in a rectangular shape. The shelves on three walls were filled with various products. chemical reagents.
¡°Officer, what¡¯s the matter?¡± As soon as we entered the door, a man in his 50s wearing a white coat said to us.
¡°I want to ask you about someone, do you know this person?¡± As I said that, I placed the screenshot of the video taken on my phone in front of the man.
The man picked up the phone and looked at it carefully, frowned and replied:
¡°I don¡¯t know this person!¡±
I looked up and stared at the boss in front of me for half a minute. I didn't find any sign of disguise on his face. He was a businessman who opened the door and there was no need to play tricks on us, so I basically could Rule out the possibility that Zhao Junxin is familiar with this boss. Then he can only go to the store to buy things. I calculated silently in my mind, and then asked again:
"This man bought something from you some time ago. I want to know what he bought."
¡°When did it happen specifically?¡± the man asked, tilting his head.
"Four days ago, 8:25 in the morning." I said the time accurately.
"Wait a moment." The man opened a thick notebook and searched carefully.
¡°Our chemical reagent store belongs to a special industry, so every time we sell a product, we will record it.¡± The man said while flipping through his notebook.
"Yes." The man pointed at a line of scrawled words and said.
"What did he buy?" I quickly stretched my head over.
"Sodium!" The man raised the notebook and placed it in front of my eyes, pointing at the information recorded in the notebook and saying to me.
¡°Did you only buy sodium?¡± I confirmed with the boss.
"Yes, that's right! Only sodium." The boss replied firmly.
I was overjoyed to get this result. After thanking my boss briefly, I ran out the door and took out my mobile phone.
Fat Lei shook his bucket waist and followed me panting. Ye Qian also ran up to me at this time, swinging her ponytail.
"What's going on? Why are you running so fast?" Ye Qian complained to me.
I made a "shh" gesture at her, then picked up the phone, dialed Lao Xian's number, and said to the other side of the phone: "Brother Xian, please check the items picked up at the crime scene now. Does it contain sodium hydroxide?"
As soon as I hung up the phone, I said to Ye Qian who was leaning next to me: "If it detects the presence of sodium hydroxide, your criminal police team will be able to arrest someone!"
After saying that, I took out a cigarette from my pocket, handed one to Fat Lei, and lit it comfortably.
"What's going on? Why don't I understand?" Ye Qian asked curiously.
I turned around and glanced at Fat Lei, who was smiling all over his face, and immediately understood that Fat Lei also knew the reason. It seemed that only Ye Qian, a novice, had not come around yet.
"Si Yuanlong, are you interested? You can tell me!" Ye Qian was so anxious that she stamped her feet on the spot.
"Ye Qian, you used to study liberal arts, right?" I teased without answering her question.
"What's wrong with studying liberal arts? Who do you look down on?" Ye Qian said loudly with her hands on her waist.
"It seems that all your junior high school science knowledge was mixed with porridge and drank up." I said with a grin.
"Si Yuanlong, I want to challenge you to a duel!" Ye Qian said as she rolled up her sleeves and stepped forward.
"Xiaolong, tell her quickly, otherwise I won't be able to stop you!" Fat Lei blocked Ye Qian and me on both sides, and said to me. (Remember the website address: www.hlnovel.com)??Ah! "Ye Qian was so anxious that she stamped her feet on the spot.
