National Forensic Doctor

Wu Junhao's squadron was sent to look for Xueyi, but no results were found in the short term.

The criminal police in the advance area took over all the surveillance videos of 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? Just bring back several months of surveillance videos without thinking?" The district bureau's picture detective policeman was cursing while scanning the videos.

District bureaus and county bureaus are at about the same level and do similar things. However, Qinghe City's Qianjin District is larger and has more people than Ningtai County because it is the main urban area.

After all, the larger the city, the more conflicts and fatalities there will be.

On the other hand, investment in the construction of central urban areas in prefecture-level cities is also high, 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 anyone else, 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.

It won't work if you are lucky, you have to look after it 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 theater projection hall broke down is recorded, so the surveillance that everyone looks at is mainly about the time before and after the camera broke down.

But when he came out at this time, he searched for nearby cameras and found Bai Yuequn easily.

He consciously avoided the camera, but he was not good enough. He avoided some, but still couldn't 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 for ordinary businesses to do monitoring as they please, so much so that even professionals may be able to get away with it.

Bai Yuequn's face kept appearing at the entrance of the shopping mall, the parking lot, and the entrance to 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 special team was in high spirits.

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 safety requirements are higher, 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 discovery, 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 everyone around Bai Yuequn over and ask them carefully.

Anyone who runs a bar, no matter whether they are their subordinates or the pony boys around them, are all show-stoppers. 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 on the corpse, 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, Bai Yuequn had another spare dagger on his leg.

The new boyfriend's position 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 the most distance-based competitive sport. At this time, Yuan Yutang woke up from his dream. His body was so weak that he might lose his fighting power as long as he was stabbed.

Bai Yuequn did not relax his vigilance and stabbed him repeatedly, intentionally 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 down on the edge of the bed. 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 death, 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 also 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 remain 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 thinking about the plan day and night. Some people 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 would be a little silly to simply give someone 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 didn't want to bring money into the group. He originally came here to commit burglaries, but now he's been killed. It would be a waste to invest resources.

"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 like this kind of eucalyptus will have to give an account sooner or later. At most, he is a man from a bar. Maybe he was promised something, just to stay up longer.

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

Jiang Yuandao said: "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 your hotel, and I’ll 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 dry and there was nothing abnormal.

So, Jiang Yuan took out the ready-made luminol reagent, put it in a watering bottle, and touched it to the bathroom wall.

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

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

The blood stains in the bathroom, as long as the DNA matches either Yuan Yutang or her boyfriend, it will be a surefire move.
