Chapter 221 Nirvana
Wu Junhao's first squadron was sent to find the bloody clothes, but no results were found in a short period of time.

The criminal police in the forward area took all the surveillance video from the theater, which provoked the police from the Graphic Investigation Squadron to complain for a while.

"Is it true that those who work in the field... can't just screen them? They just took months of surveillance video and returned it without thinking?" the police officer from the District Bureau scolded while scanning the video.

District bureaus and county bureaus are at about the same level, and they do similar things.However, for example, the forward area of ​​Qinghe City, because it is the main urban area, is larger than Ningtai County and has more people.

After all, the larger the city area, the more conflicts and conflicts, and the more murders.

On the other hand, the construction investment in the central urban areas of prefecture-level cities is also high, and the monitoring is relatively good, so map investigation can play a role.

Qinghe city police officers are quite busy every day.

For other cases, not to mention bringing back several months of surveillance video, even a few days of surveillance, no one may have time to watch it.

The murder case will not work, and you have to watch overtime if you work overtime.

The few scolded and scolded, but they quickly put together the surveillance video, roughly distributed the distribution, and watched it with their thick glasses.

Everyone basically looks backwards in time.

Moreover, the time when the camera in the auditorium of the theater broke down is recorded, so the monitoring that everyone sees is mainly before and after the time when the camera broke down.

The broken camera itself provides little information.It's like a conscientious star, just doing what ordinary stars would do, and then being smashed.

But when this time point came out, and then searched the nearby cameras, it was easy to find Bai Yuequn's figure.

He consciously avoided the camera, but his rank was not enough, so he avoided some of them, but he couldn't avoid more of them.

In fact, many places with dense cameras not only have no blind spots, but some areas will have repeated coverage.

The current monitoring cost is really too cheap, especially for ordinary businesses to do monitoring and do whatever they want, so that professionals may be caught.

Bai Yuequn's face kept appearing at the entrance of the 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 the No. Alibi".

The task force that was just established, everyone in the upper and lower ranks are all refreshed.

Although there is still not enough evidence to submit for inspection and prosecution, but at this point, it is almost certain that it is Bai Yuequn.

And these methods of his, although they seem to be useful, or even very useful, are actually of little significance to the police.

In the judicial system of the United States, at this point, it is actually possible to sue.

Homicide cases in China have higher requirements, and further evidence has to be found, but everyone's confidence has been greatly increased.

As Huang Qiangmin said, a single evidence does not stand. Conversely, if multiple pieces of evidence appear, the case will stand.

For a current case, there is actually a lot of evidence, it depends on how to find it.

Lei Xin's first thought was to pull everyone around Bai Yuequn over and question him carefully.

Those who run the bar, no matter whether they are subordinates or the pony boys around them, are all scumbags. As long as they sit in the interrogation room, they will soon become well-behaved and talkative.

Jiang Yuan turned around, and Wu Jun went to study the wounds of the corpse again, and turned the murder weapon out of a mold.

The mold is not very good, but there are actually not many sabers with double-edged blades, at least not many famous ones.

Soon, Ma Zai confessed that Bai Yuequn had bought two Spartan V14s.

At the same time, Bai Yuequn has also been proven to have many years of fencing experience - not fencing for fun, but fencing that is really powerful and can pierce the gut.

After seeing the picture of Sparta 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. .

By the way, Jiang Yuan reconstructed the crime scene and gave a simple demonstration to Huang Qiangmin and others.

When the murderer entered, he first pointed at Yuan Yutang's new boyfriend, holding a dagger in both hands, aiming at the direction of the heart, stabbed in with one knife, and pulled out the dagger smoothly.

If he hadn't pulled it out, Bai Yuequn still had another spare dagger on his lap.

The position of the new boyfriend did not change, 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, and when he saw Bai Yuequn, he got up and tried to block him with a pillow or quilt.

Bai Yuequn may or may not have said something, but he was holding a 40 cm long dagger, occupying a favorable terrain, adjusted his position a little, and stabbed Yuan Yutang's arm easily by swinging his sword.

Fencing is the most competitive sport that pays attention to distance. At this time, Yuan Yutang just woke up from a dream, and his body is weak and singing every day. As long as he is stabbed, he may lose his combat effectiveness.

Bai Yuequn did not let down his vigilance, and stabbed many times, deliberately not hitting the fatal part, causing Yuan Yutang to gradually lose blood.

After playing like this for a few minutes, Yuan Yutang's bleeding caused him to fall to the side of the bed, and Bai Yuequn stepped forward to completely end his life, and then stabbed him many times again in a venting manner.

After Yuan Yutang's upper body was stabbed, Bai Yuequn casually stabbed another corpse on the bed before entering the bathroom to take a shower, wash clothes, and rinse the floor.

For the alibi, his time must be very tight, but he should have made preparations in advance. The clothes are relatively special materials or shapes, so as to avoid too much bloody smell on his body, and at the same time, he will not smear his hair. Crumbs remain on site.

In the end, Bai Yuequn left the scene stepping on a pool of blood, a little hurried, but basically completed the pre-plan.

"Looking at it this way, his plan was not made in a day or two." After hearing Jiang Yuan's explanation, especially the preparation of weapons and clothes, Huang Qiangmin couldn't help but sigh with emotion.

Wu Jun took it for granted: "These premeditated murderers, none of them are planning day and night. It's just that some people are unlearned and incompetent, and some people are not professional..."

"In this case, he should have to step on the spot many times." Huang Qiangmin explained the purpose.

Wu Jun couldn't help but nodded: "But it's still indirect evidence."

"It's best to find evidence, videos or photos of him appearing outside the screening hall during the film's screening time." Huang Qiangmin actually had a similar idea long ago, 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's a little silly to simply give such a suggestion to others.

It is not impossible for people to think of it, and there are obviously objective reasons for not doing it after thinking about it.

Huang Qiangmin himself didn't want to bring money into the group. He originally came here to engage in burglary, but now that it's a murder case, it's a waste of resources.

"Bai Yuequn's witness, his boyfriend, is he still unwilling to confess?" Huang Qiangmin turned to ask Wu Junhao.

"Not yet, the time is too short." Wu Junhao didn't care.

As far as his experience is concerned, such witnesses in such cases will have to confess sooner or later.At most, it's a man from a bar, maybe he was promised something, just stay longer.

Mentioning this boyfriend, the scene that was being reconstructed in Jiang Yuan's mind suddenly extended.

Just listen to Jiang Yuan said: "I remember Bai Yuequn said that after watching the movie, he went to the hotel next door with his boyfriend to get a room. After that, they took a shower before going to bed, right?"

"Yes."

"This means that if there are bloodstains left on Bai Yuequn's body, he will take the opportunity to wash them in the hotel, and the bloody clothes can also be temporarily stored and processed..." Jiang Yuan paused, then got up and said, "They live here Send me the room number of your hotel, and I will scan it to see if I can get blood."

Most of the hotel rooms are opened randomly, and Bai Yuequn probably won't prepare cleaning agents in advance.

And if there is no professional cleaning agent, it is difficult to completely remove the blood stains.

At least not for a short time.

Jiang Yuan went straight to the Wanda Hotel with the survey box in hand.

Room 602, where Bai Yuequn slept before, has actually been sealed up. Jiang Yuan and Wu Jun went upstairs with the waiter, and when they checked the door, they saw that the bathroom was dry and there was no abnormality.

So, Jiang Yuan took out the ready-made luminol reagent, put it into a watering can, and brushed it against the wall of the bathroom.

"Turn off the lights." Wu Jun reminded and turned off the lights.

Yingying blue light immediately appeared, and there were quite a few of them.

The blood stains in the bathroom, as long as the DNA matches any of Yuan Yutang and her boyfriend, it is a nirvana.
