Wu Junhao's squadron was sent to look for the bloody clothes, but no results were found in the short term.
The criminal police in the advance area took over all the surveillance videos from the theater, which made the policemen of the Picture Detective Squadron complain for a while.
"Is it true that those who work in the field...can't screen them? They just brought back several months of surveillance videos without thinking?" The district bureau's picture detective policeman cursed while scanning the videos.
District bureaus and county bureaus are at about the same level and do similar things. However, Qianjin District in Qinghe City is larger than Ningtai County and has more manpower because it is the main urban area.
After all, the larger the city, the more conflicts and murders there will be.
On the other hand, the central urban areas of prefecture-level cities also have high investment in construction, and surveillance is relatively better, so picture reconnaissance can play a role.
The picture detective police in Qinghe City are quite busy every day.
If it were another case, let alone a few months of surveillance video, even if it was a few days of surveillance, no one would have time to look at it.
That's not the case with murder cases. You have to watch overtime even if you work overtime.
Several detectives scolded each other, but they quickly gathered the surveillance videos together, roughly distributed them, and each of them looked at them through thick glasses.
Everyone basically watched it backwards in time.
Moreover, the time when the camera in the cinema projection hall broke down is recorded, so the surveillance you see is mainly about the time before and after the camera broke down.
The broken camera itself provided no information. It was like a conscientious star, just doing what ordinary stars would do, and then was ruined.
But when I came out at this time, I searched for nearby cameras and found Bai Yuequn easily.
He consciously avoided the camera, but his level was not high enough. He managed to avoid some, but still could not avoid more.
In fact, in many places where cameras are densely packed, not only do there no blind spots, but some areas also have repeated coverage.
The cost of monitoring nowadays is really too cheap, especially when ordinary merchants can do monitoring as they please, so much so that even professionals may get caught up in it.
Bai Yuequn's face kept appearing at the entrance of the shopping mall, the parking lot, and the entrance of the parking lot.
Although there is still no direct evidence to prove that Bai Yuequn damaged the monitoring equipment in Screening Room 2 that day, Bai Yuequn was at the scene during the time when the monitoring equipment was damaged. This "evidence of presence" weakened his "
alibi”.
The newly formed task force and everyone in the team were very energetic.
Although there is still not enough evidence to submit for prosecution and prosecution, at this point, it is almost certain that it is Bai Yuequn.
Although these methods of his seem useful and can even be said to be very useful, they are actually of little significance to the police.
In the American judicial system, at this point, you can actually prosecute.
Domestic murder cases are more demanding, and further evidence needs to be found, but everyone's confidence has greatly increased.
As Huang Qiangmin said, evidence alone does not stand up. On the contrary, if multiple pieces of evidence appear, the case will stand up.
For a current case, there is actually a lot of evidence, it just depends on how you look for it.
The first thing Lei Xin thought of was to pull over everyone around Bai Yuequn and ask them carefully.
Anyone who runs a bar, no matter whether they are their subordinates or the pony boys around them, are all fools. As long as they sit in the interrogation room, they will soon become well-behaved and talkative.
Jiang Yuan turned around and went to study the wounds on the corpse with Wu Jun and made a mold of the murder weapon.
The mold is not very good, but there are actually not many double-edged sabers, at least not many that are famous.
Soon, Ma Zai revealed that Bai Yuequn had bought two Spartan V14s.
At the same time, Bai Yuequn was also proven to have many years of experience in fencing - not fencing for fun, but real fencing with powerful thrusts that can penetrate the intestines and stomach.
After seeing the pictures of the Spartan V14, both Jiang Yuan and Wu Jun felt that this thing could be used as a short-handled Western sword. Based on the comparison between the height of the deceased and the height of the murderer, the direction of the wound was also very reasonable.
.
Jiang Yuan also reconstructed the crime scene and gave a simple demonstration to Huang Qiangmin and others.
When the murderer entered, he first faced Yuan Yutang's new boyfriend, held a dagger in both hands, aimed at the heart, stabbed him in, and successfully pulled out the dagger.
If it was not pulled out, there was another spare dagger on Bai Yuequn's leg.
The new boyfriend's posture remained unchanged and a large amount of blood flowed out, forming a pool of blood under the bed.
Yuan Yutang was awakened by the movement around him. When he saw Bai Yuequn, he stood up and tried to block him with a pillow or quilt.
Bai Yuequn may or may not have said something, but he held a 40-centimeter-long dagger, occupied a favorable terrain, adjusted his position slightly, and stabbed Yuan Yutang's arm easily by swinging the sword.
Fencing is a competitive sport that emphasizes distance. At this time, Yuan Yutang woke up from his dream. His body was so weak that he might lose his fighting power if he was stabbed once.
Bai Yuequn did not relax his vigilance and stabbed Yuan Yutang many times, intentionally not hitting the fatal part, causing Yuan Yutang to gradually lose blood.
After playing like this for a few minutes, Yuan Yutang was bleeding and fell to the bedside. Bai Yuequn then stepped forward and completely ended his life, and then stabbed him several times in a venting manner.
After Yuan Yutang's upper body was stabbed to pieces, Bai Yuequn casually stabbed another corpse on the bed before entering the bathroom to take a shower, wash clothes, and rinse the floor.
In order to prove his alibi, he must be very pressed for time, but he should have made preparations in advance. The clothes are made of relatively special materials or shapes to avoid being stained with too much blood smell, and at the same time, he will not expose his hair to the skin.
The crumbs were left on site.
In the end, Bai Yuequn left the scene in a pool of blood, a little hastily, but basically completed the pre-plan.
"Looking at it this way, his plan was not completed in a day or two." Huang Qiangmin couldn't help but sigh after listening to Jiang Yuan's explanation, especially the preparation of weapons and clothes.
Wu Jun said in a accustomed manner: "None of these people who commit premeditated murders are planning and planning day and night. Some of them are uneducated and have poor professional skills..."
"In this case, he should have to visit the spot many times." Huang Qiangmin explained his purpose.
Wu Jun couldn't help but nod: "But it's still indirect evidence."
"Then it would be best to find evidence, videos or photos of him appearing outside the screening room during the movie's screening time." Huang Qiangmin actually had a similar idea, but he has always been hesitant.
Because this plan requires a lot of manpower, and the jurisdiction of the case is actually in the hands of the criminal police brigade in the forward area, that is, Captain Lei Xinlei. It is a little silly to just give people such a suggestion.
It’s not like people wouldn’t think of it. If they think of it but don’t do it, there are obviously objective reasons.
Huang Qiangmin himself did not want to bring money into the group. He was originally here to commit burglary, but now it has become a murder case. The investment of resources will be a huge loss.
"Bai Yuequn's witness, his boyfriend, still unwilling to give an explanation?" Huang Qiangmin turned to ask Wu Junhao.
"Not yet, the time is too short." Wu Junhao didn't take it seriously.
From his experience, witnesses in this kind of case will have to give an account sooner or later. At most, they are men from bars. Maybe they were promised something and stayed up longer.
Mentioning this boyfriend, the scene being reconstructed in Jiang Yuan's mind suddenly expanded.
Just listen to Jiang Yuandao: "I remember Bai Yuequn said that after watching the movie, he and his boyfriend went to the hotel next door to book a room. Then, they took a shower first and then went to bed, right?"
"That's right."
"This means that if there are any residual blood stains on Bai Yuequn's body, he will take the opportunity to wash them in the hotel, and the blood clothes can be temporarily stored and processed..." Jiang Yuan paused, stood up directly and said: "They live there
Send me the room number of the hotel, I will go over and scan it to see if I can detect blood."
Most of the hotel rooms are randomly opened, and Bai Yuequn probably won't prepare cleaning chemicals in advance.
And without professional cleaning agents, blood stains are difficult to completely remove.
At least not in the short term.
Jiang Yuan took the survey box and went straight to Wanda Hotel.
Room 602, where Bai Yuequn had slept before, had actually been sealed. Jiang Yuan and Wu Jun followed the waiter upstairs. When they looked at the door, they saw that the bathroom was completely dry and there was nothing unusual.
So, Jiang Yuan took out the ready-made luminol reagent, put it into a spray bottle, and touched it to the bathroom wall.
"Turn off the lights." Wu Jun reminded and turned off the lights.
Glittering blue light appeared immediately, and there were quite a few of them.
If the blood stains in the bathroom match the DNA of either Yuan Yutang or her boyfriend, it will be a surefire success.
