Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

The forensic doctor has been busy for a day, but there are not many clues.

Wang Changjiang, who was sitting on the inside of the chair, moved his body and said: "The cause and time of death of the four victims are basically consistent with the judgments of the current investigation. We have already conducted autopsies on two of the corpses. No other special circumstances have been discovered so far.”

Qin Yong nodded. The biggest role of forensic medicine is to further determine the cause and time of death through autopsy when the frontline criminal police and investigators are unable to judge the cause and time of death.

Or identify the deceased through his or her DNA information.

Of course, this part of the work overlaps with the on-site survey work. Whoever comes in first will do it first.

In most criminal investigation detachments or criminal police brigades, forensic investigation and forensic medicine are complementary police types.

In some places, the forensic doctors are stronger and have a higher say. In some places, the criminal investigation police are stronger and have a higher say.

In the Haizhou City Criminal Investigation Detachment, the original forensic and investigative powers had almost the same say. Wang Changjiang and Liu Guodong were on par with each other in terms of strength, and in their respective fields, the province's rankings were basically at a relatively equal level.

However, since Lu Chuan joined the current exploration office more than a year ago, the strength of the current exploration office has experienced an explosive growth process.

Coupled with the [-] million donated by Qiangsheng Group, the strength of the Haizhou Criminal Investigation Detachment's current investigation office is one of the best in the province, both in terms of hardware and software.

Especially in terms of hardware, Qin Yong also dares to make gestures across the country.

After all, not everyone has [-] million.

It's great to have money.

"Others, please express your opinion."

"Let me talk about surveillance first."

Sun Jun took the PPT reading pen on the conference table and turned on the projection equipment.

"First let's talk about the surveillance video of the building in the rental house. We checked the video surveillance equipment and it is indeed not in working condition."

"but……"

Sun Jun switched the PPT, which was a partial photo of the surveillance computer: "The surveillance equipment in the building was not damaged, but someone deliberately unplugged the surveillance cable."

Unplugged on purpose?
The police officers who participated in the case analysis meeting were alerted when they heard this. This was a major clue, because during the investigation, some tenants reported that the monitoring equipment was damaged and the landlord failed to repair it.

"Can you find out when it was pulled out?"

It doesn't matter whether the monitoring line is pulled out or not, the key is the time to pull out the monitoring line.

If it had been pulled out long ago, that would be fine, but if it had been pulled out before the incident, then the landlord would be highly suspected of committing the crime.

"We checked the monitoring in the computer, and the last recorded time was March this year."

March?
Everyone around the conference table straightened their backs and sat back in their chairs.

Since the earliest video recording time in the computer was in March this year, it means that it should have been more than half a year since the video cable was unplugged.

Viewed this way, the landlord’s suspicion of committing the crime is basically gone.

"The landlord should not be the murderer, otherwise, it would be too obvious."

"That's not necessarily true. What if the other party does the opposite?"

"In our previous cases, the thief was called "catch the thief", and the person who reported the crime was the murderer. There were many cases."

"I don't agree with the view that the landlord is the murderer, because it is unlikely that the other party planned the murder six months ago. If the other party really started planning the murder six months ago, he would not have left so many traces and clues at the scene."

"Okay, even if the other party didn't plan the murder six months in advance, why did he unplug the monitoring line? The equipment was not damaged, so why did he lie and say that the equipment was broken?" "Isn't this simple? The reason why the other party did this is nothing more than It’s just to save electricity. After all, monitoring equipment consumes a lot of electricity, and it adds up to a lot of money over time.”

The surveillance equipment in the building is the focus of the criminal police investigation, so everyone discusses this point more.

Qin Yong thought for a while and then asked:

"How is the surveillance investigation on the road outside the building going?"

Sun Jun shook his head: "There are no big clues."

"There are two streets outside the house. There are surveillance cameras at the intersections of these two streets, but there is no surveillance near the rental house."

"We checked the time period when the crime occurred last night, and there were no special findings in the surveillance of the two intersections nearby."

"According to the clues provided by the current investigation, the footprints left by the other party were high-heeled shoes. We focused on the information of women in nearby surveillance cameras."

"But a woman with a height of 178cm and a weight of 70kg was not found."

"Personally, I prefer that the other person is a man, and he wears high heels to deliberately hide his gender."

Qin Yong looked at Lu Chuan. Lu Chuan had the most say in this matter.

Lu Chuan used to sit behind Liu Guodong when attending case analysis meetings. In recent times, he followed Liu Guodong and sat in the inner circle of the conference table.

This is the rise in status brought about by strength.

In every case analysis meeting, the people sitting in the inner circle of the conference table are the middle-level people of the criminal investigation detachment.

This conference room is also the conference room for morning meetings. The middle-level people sitting in the inner circle have name tags on the tables.

They were not in the middle level, only Zhang Hui and Lu Chuan. Zhang Hui was in the inner circle because Ren Qiang was recuperating in the hospital and was acting as an agent for the second operation team.

Lu Chuan was different from him. In this situation, he relied on his strength to sit in the inner circle, making it easier for Qin Yong to ask questions.

"male!"

Lu Chuan's answer was relatively certain, unambiguous and decisive.

"Xiao Lu, can footprint analysis determine gender?"

The people sitting here are all experts in criminal investigation. Although they may not necessarily know that much about spot investigation technology, they still have some grasp of some basic situations.

Footprint identification and analysis is inherently difficult, and gender identification through footprints is definitely very difficult, because some people are born with smaller feet, but they can be male, and some people are born with big feet, and she can also be female.

"Basically sure."

Lu Chuan replied affirmatively and then explained: "From the identification and analysis of the footprints, the other party's shoe size is 43, his height is about 1 meters, the error is not more than two centimeters, and his weight is about 78 kilograms."

"Judging from the ratio of height to weight and shoe size, this is a typical male characteristic."

"Generally speaking, even if women are 1 meters tall, the proportion of shoe sizes is usually 78, and very few can reach size 40."

"This is determined by the different physiological structures and body proportions of men and women."

"In addition, I reconstructed the crime scene based on the blood spray at the scene."

"I won't talk about the specific process for now, just talk about the puncture wounds on the arteries of the two male victims." (End of Chapter)
