While waiting for the physical evidence to be extracted, Lang Heng accompanied Jiang Yuan and looked through the pictures of various evidence with the criminal police present.
There are a lot of physical evidence involved in this case. Because the investigation by the special case team was not going smoothly, a lot of physical evidence was also extracted. But after looking through the photos of all the physical evidence, Huang Qiangmin felt something and said, "The windows are all closed, and the door is the only way in and out. The door lock... can be said to be the key evidence."
Huang Qiangmin has been the captain of the criminal police for many years and is quite experienced in dealing with such murders. He looked at Jiang Yuan with some satisfaction.
Huang Qiangmin guessed that when Jiang Yuan asked him to collect evidence, he specifically mentioned the door lock, which was probably just an intuition. Because at that time, Jiang Yuan had not read the evidence materials completely, and did not know the evidence in the case. Not only did he lack evidence pointing directly to the murderer, but the evidence in the room was also not strong enough. If it was not intuition, but he could make an inference without reading the complete evidence materials, it would be even better.
Huang Qiangmin felt that he really should win a Bole Award or something like that!
"We checked the door lock before." Lang Heng knew what Jiang Yuan and the others meant, and said, "In fact, it was because we checked the door lock that we caught Mai Zuqing. The door lock in the victim's house did not have typical signs of being opened, so the murderer probably had a key, or he had to trick the door open."
"There is a key...it could also be a lover?" Huang Qiangmin was not trying to argue, he was just raising a possibility.
Lang Heng shook his head slightly. "We also inquired about this aspect indirectly. The victim, Sui Yingxue, is very busy taking care of two children. She is a full-time housewife. She has to buy groceries and cook every day, and pick up and drop off the children. We also talked to some of her girlfriends, read her WeChat, and checked the apps on her phone. Basically, there is no possibility of her having a lover."
The previous evidence is fine, but after checking the phone, it was found to be innocent, so there is a high probability that he is innocent.
However, criminal police are always skeptical, so Huang Qiangmin asked one more question: "Is there a second mobile phone?"
"We didn't find the second phone." Lang Heng paused and said, "Unless she didn't leave the second phone at home, the scene was turned upside down. She didn't have a workplace... Of course, this possibility cannot be ruled out."
Lang Heng didn't say he was dead. There are many cases that are beyond the thinking state of ordinary people. To put it in a more literary way, they are above the ordinary level, especially cases involving murders of passion. Think about it, the murderer would be willing to kill for it, and the emotion must be extremely strong. No matter what outsiders think, the emotions between the people involved are often extraordinary.
Lang Heng couldn't guarantee whether Sui Yingxue had any emotional debts outside the family.
Moreover, 10 years ago, social media was not as prosperous as it is today, and people still made offline appointments, hooked up offline, and committed adultery offline.
"The lock is here."
Lang Heng did not follow Huang Qiangmin's speculation and still placed his hopes on Jiang Yuan.
The police officers brought in several boxes of evidence one after another.
Jiang Yuan put on gloves and scanned the evidence bag. Finally, he asked everyone to make room and checked the locks first.
The guesthouse of the Criminal Police Detachment receives three special task forces on a daily basis. Even in the restaurant, the waiters are skilled in using screens to enclose an independent space.
Jiang Yuan couldn't open the lock immediately, so he used tools to check it out first.
First of all, the lock has not been subjected to violent treatment, that is, no one has used a door pick to pick the lock, or sprayed it with a 97-2 type explosion-proof gun. There are actually only two remaining ways to open the lock, one is to open the lock with a key, and the other is to open the lock with a technical method.
Most of the technical lock picking is the tricks used by lock pickers. The common ones are using hooks to pick locks and using tinfoil to pick locks.
As for the police's trace inspection, there are also professional countermeasures, such as "technical unlocking through typical trace identification."
Because technical unlocking is actually not a new invention. In other words, various inventions have been played out decades ago, and the lock kings and thieves of the new era are no longer geniuses in mechanical locks. It can be deduced that existing technical unlocking methods will have existing traces.
That is, the "typical" and "stable" unlocking traces.
The unlocking method is classic, so the unlocking marks left behind are naturally typical. The more you practice unlocking, the more fixed the unlocking movements become, and the more stable the marks left behind become.
In the early years, when burglary was more prevalent, some skilled police trace detection experts were not only able to recognize technical unlocking marks in locks, but could also identify the operation marks of some famous local thieves based on the differences in the marks.
It can be said that this is an excellent example of people being afraid of becoming famous and pigs being afraid of getting fat.
Today's technical means are naturally more advanced and complete, but the number of cases of home invasions has decreased, causing the development of such technology to lag behind.
Jiang Yuan checked it carefully and pondered.
"What do you mean?" Lang Heng became anxious when he saw his expression.
"At least the lock has not been opened by means of lock bumping." Jiang Yuan's answer was similar to the previous trace inspection judgment of the task force.
Lang Heng couldn't help but sigh and said, "From this perspective, this road is still not feasible."
Jiang Yuan did not comment, and repeatedly looked through the removed lock. To be honest, Jiang Yuan had a level 6 tool mark identification skill, but it was not very appropriate to use it here, because the first thing to do now was to find the mark, not to determine who the mark belonged to.
LV4 crime scene investigation and even LV3 vehicle trace identification can play a certain role at this time, but they can only provide a little help and cannot solve the problem.
The atmosphere in the room suddenly became dull. Huang Qiangmin looked anxious and said, "It's a pity that there was no blood at the scene. Otherwise, Jiang Yuan would have solved burglary murders through bloodstains more than once or twice."
"Bloodstains can indeed reveal a lot," Lang Heng agreed.
Huang Qiangmin curled his lips and thought to himself, the many things you said and the many things I said are not the same as the same many.
However, there was no blood in this case, so Jiang Yuan's blood analysis skills could not be used, which was a great pity for Huang Qiangmin. In his mind, among the various technical means Jiang Yuan mastered, this one was the most useful.
"Or should we ask Old Liu to come and take a look?" Huang Qiangmin still knew how to use people. Seeing Jiang Yuan fell into deep thought, the first person he thought of was Liu Jinghui.
Jiang Yuan did not object, nodded, and then said: "However, if you want to ask Director Liu, you have to collect more information and make it more accurate."
"We can bring back the task force from that year. For a case from 10 years ago, all the people from that time are still here." Lang Heng said.
Jiang Yuan poked his head into the evidence box and rummaged through it, then said, "This case may require Director Liu to expand his thinking. If possible, find a few more members of the special investigation team from that year. Some memories are clearer than what is in the files."
"I'll think of a way." Lang Heng nodded.
There is no need for hidden rules or anything like that. In any unit, what is written in the files is not completely consistent with everyone's daily experience and memories. At the very least, the content in the files must be able to withstand scrutiny, especially the files of the judicial department. Even if it is an investigation file, the content inside is very strict.
However, these files are all for the service of the court, or in other words, for the sake of fairness and justice. As far as solving cases is concerned, it is difficult to find answers if the information is too conventional.
"If possible, find a few more former members of the task force. It shouldn't be easy to solve this case purely from a technical perspective." Although Jiang Yuan had just started working on the case, given his technical level, he could tell at a glance that this case was definitely difficult.
Lang Heng understood a little bit and said to himself, "Liu's reasoning... is indeed quite good. How about this, I will reorganize the task force according to the personnel list of the 430 task force 10 years ago. Although the personnel will definitely change, I will try my best to transfer those who are still in the detachment and in Changle City!"
