National Forensic Doctor-Chapter 897 - 835: Confirm One Person

As long as there are enough conditions, the scope will be sufficiently narrow.

It’s similar to the often-told story by the matchmakers in marriage agencies; if one requires certain attributes in men such as height, weight, profession, education, income, owning a house and a car, residence registration, parents’ professions, etc., even if each requirement is very ordinary, the resulting "octagon warrior" will be a rare existence.

Likewise, when Jiang Yuan lists the suspects as "A∩B∩C∩D∩E∩F∩G," the scope has indeed become quite narrow.

Ni Cha was so excited that his voice became hoarse.

"Close the door," Ni Cha whispered.

Zhong Renlong was stunned for a moment, feeling that this command sounded somewhat familiar.

The people under him had already closed the meeting room door, and hearing Ni Cha’s command, they turned around and locked it twice.

Upon hearing the sound, Ni Cha breathed a sigh of relief and then commanded, "No need to leave, just filter people here. Everyone hand over your cell phones, and don’t make any strange movements, otherwise don’t blame me for being impolite."

His gaze was sharp as he looked at his subordinates, and he also looked towards the Chinese members.

Everyone complied without objection and handed over their phones.

Subsequently, Ni Cha had people print out the list, and a group waited as a few people filtered through it.

The conditions were already laid out, and not too many people were needed to work on it, so Ni Cha simply had several copies of personnel files printed out and handed them to Jiang Yuan and others to review, so they wouldn’t get too bored.

However, these personnel files were terrifyingly detailed.

Huang Qiangmin, taking it in his hands, didn’t even need translation; just by looking at the bolded names and the long paragraphs following them, he couldn’t help but ask, "Why are there so many? Is this the style of local police... uh, has this case been studied so thoroughly?"

Zhong Renlong said, "The list of individuals involved in the death case of the Member of Parliament Lunen was sorted out two years ago, with a lot of content, some of it very detailed, including personal histories down to whether each ex-girlfriend was actually female to that extent."

"So detailed? Not sorted out by the police?"

Chu Guanliang, who had long been residing in Malaysia and was very familiar, said, "The media loves to exaggerate matters; it’s quite clear they took a cue from the Kennedy assassination, sourcing materials from various facets, investigating everyone once until multiple warnings stopped them."

"And yet, they still couldn’t find the murderer?"

"The focus of the media is entirely different from ours. Plus, they sometimes intentionally distort the events to craft dramatic stories, ignoring logic, using their data merely adds more suspects, making it seem as if everyone is suspect..." Zhong Renlong said, shaking his head.

Older detective novels or TV dramas always liked to create a pattern filled with mystery, wishing every character who appeared and spoke a line was suspected by the audience.

However, real-life police have resource constraints, even in domestic major cases, it’s not feasible to investigate everyone without limits. On the other hand, investigations always leave traces, and in the American judicial system, every investigated suspect becomes a boomerang for defense lawyers, making a case with all members suspected likely to collapse with a 99% probability.

The domestic environment isn’t as harsh; the police can continue to expand the investigation scope during the investigation period if they have the capacity, but investigating a suspect is not a matter of a few sentences. A complete investigation, even if the suspect is believed not to be the culprit, still requires forming a chain of evidence with witnesses and material evidence and relating them in chronological order to form documentation. If all are suspects, the workload could make a criminal police squad doubt their life purposes.

Therefore, media involvement in judicial cases is primarily about spectating and even intensifying the spectacle. After all, educated media personnel, who only studied communications, still fall short of competing with legal studies in service industries.

"Identify one person," a police officer came to Ni Cha’s ear and softly spoke.

Ni Cha’s eyes flashed, "Is the list finished? How many are left?"

"It’s finished, there’s only one person fitting the criteria," the reporting police officer took a deep breath, with only one person out of five hundred meeting the criteria, those who don’t understand probabilities might also recognize this as a low-probability event—indeed, as the high probability should be that no one meets the conditions.

Ni Cha couldn’t help but take a deep breath either, instantly understanding the pressure his subordinate was under.

Looking around, Ni Cha no longer hid his concern and asked in a low voice, "Who is it?"

"Badawi." The police officer reporting didn’t say it lightly.

Ni Cha’s spirit tightened, "Member of Parliament Renne’s son-in-law?"

As soon as he spoke, Ni Cha’s spirit relaxed again. Fortunately, it was just Member of Parliament Renne’s son-in-law!

"Badawi is a professional golfer. After marrying Renne’s daughter, he devoted himself to playing golf, often playing over 100 games a year, spending a lot, but perhaps due to talent and other reasons, Badawi’s performance has not been good. In this regard, Renne is probably very dissatisfied with his son-in-law, I heard that the two even had a couple of arguments..." His information towards the end came from media articles.

"Let’s not look for Badawi yet. Hmm...if the suspect is Badawi, this case will be much easier to handle." Ni Cha said, not sure if he felt relieved or regretful, then he shook his head and instructed, "First, we need to collect evidence, retrieve all the video materials, find all parts involving Badawi and mark them, draw the timeline of his activities, especially check the state when Badawi left, and see if he changed clothes..."

Ni Cha’s orders were all about establishing an evidence chain. In the words of the forensic doctor Li Changyu, it’s about the relationship between physical evidence, suspects, victims, and the crime scene. Among these four, if you can establish the relationship between any two, the case might be solved; if you can establish three or more, it’s virtually a closed case.

For example, the relationship between the suspect and the victim is one such relationship. Knowing just this, some cases can be solved. If not enough, if you could prove the suspect and the victim were both at the crime scene, the probability of solving the case is also very high. By another combination, if you can establish the relationship between physical evidence, the victim, and the crime scene, it similarly has a high possibility of proving the suspect’s guilt.

Of course, investigating a case is the lowest requirement within the judicial system at home. At the stage of submitting for inspection, it usually requires that all four aspects are covered, with additional evidence such as witness testimonies, suspect confessions, timelines, etc., forming a complete evidence chain. The same goes for court proceedings and death reviews.

Facing a case such as the "Member of Parliament Renne Drowning Case," Ni Cha couldn’t take it lightly and was eager to gather as much evidence as possible, but he also couldn’t afford to delay too long. First, to confirm some evidence, then proceed with the arrest, and continue investigating slowly afterward.

Thinking this way, Ni Cha gave further instructions to his two subordinates, then went to the corner to make a phone call.

Jiang Yuan and others sat at the other end of the conference table, exchanging glances.

It was still Chu Guanliang finding it hard to adjust, scratching his head, "Is our job...over just like this?"

"Ensuring Captain Jiang is unharmed, this job is perfectly done," Mu Zhiyang, with his shirt open, unashamedly showed the bulletproof vest underneath. He had been wearing it like this the past few days, occasionally adding a ceramic plate. Only someone who has been shot knows the best way to protect themselves.

Chu Guanliang laughed and shook his head, "I thought it would be like when I was in criminal investigation, investigating, gathering evidence, running to dozens of places on strong legs, and in between maybe even adjusting the investigation direction..."

"It’s still like that," Huang Qiangmin nodded to Chu Guanliang, saying, "That’s how we, regular detectives, work."

"Then..." Chu Guanliang gestured towards the front.

"Ni Cha’s team has also been backlogged for two years, do you think they enjoy backlog?" Huang Qiangmin scoffed, then softened his tone, "Just like DNA evidence, even if a single hair can solve the problem, it doesn’t mean the problem is just a single hair."

"Philosophical!" Chu Guanliang was catching on to Huang Qiangmin’s way of thinking, starting to proficiently flatter.

In the future, they were all going to be around Jiang Yuan; it wouldn’t hurt Chu Guanliang to ingratiate himself with Huang Qiangmin, the police liaison.

Wang Chuanxing, Cui Xiaohu, and other young officers were not sure how to express their feelings.

Unlike Huang Qiangmin and Chu Guanliang, who had gradually moved away from frontline police work, Cui Xiaohu and Wang Chuanxing were younger and still wanted to learn more.

But with Jiang Yuan solving cases like this, Cui Xiaohu, Wang Chuanxing, and others really didn’t know what they could learn.

"When Badawi returned to his room, he had taken off his shirt," one officer found Badawi in the video database half an hour after the incident.

Everyone crowded over to look.

On the screen, Badawi was seen bare-chested, displaying his muscular torso. He was clutching a crumpled shirt in his hand, and his pants and shoes were still wet.

"Go arrest him," Ni Cha was not willing to wait any longer. Even though this evidence was still far from proving Badawi was the murderer, as far as investigative requirements were concerned, Ni Cha felt it was sufficient.
