Chapter 767 Chen Jianguo's Report: The Case Investigation Has Reached a Bottleneck
It could be said that Qin Chuan's words were quite harsh and showed a lot of disrespect to Chen Jianguo, but Chen Jianguo was also well aware that his handling of the case had indeed fallen short of expectations.
Nearly two days have passed since the incident, yet the police haven't even narrowed down the suspects. Without identifying any suspects and without obtaining any valuable clues or evidence at the crime scene, it's a miracle this case doesn't become a cold case, let alone be solved in three days.
If such a horrific family annihilation case remained unsolved, Chen Jianguo was well aware of the immense impact it would have on Qin Chuan. Qin Chuan was a bureau chief parachuted in from another province; how long could he possibly hold the position? Probably no more than two or three years. If this case remained unsolved, Qin Chuan would likely be unable to leave the bureau for some time.
Don't be fooled by Qin Chuan's recent achievements in Nanchuan City. The anti-drug work has been remarkably effective, and most smuggling networks have been dismantled. However, merits are one thing, demerits are another. Success doesn't excuse mistakes. If this case also fails to be solved, the impact on Qin Chuan will be unimaginable.
As the deputy director, Chen Jianguo was naturally aware of this, which was the main reason he reported to Qin Chuan so early this morning. Since no breakthrough had been achieved, it was crucial to report to the leadership as soon as possible, rather than waiting until the three-day period had passed before reporting to Qin Chuan and claiming there had been no progress. If even a single suspect hadn't been identified, then it wouldn't just be Qin Chuan's harsh words that awaited him; even the deputy director himself would question his competence.
"Director Qin, this case is indeed quite difficult. We have examined the crime scene four times, but we haven't found any particularly valuable clues. It's possible that the suspects meticulously planned and arranged these cases. Apart from those few sets of footprints, they really didn't leave anything else at the scene."
Chen Jianguo truly did his best. He went to the crime scene and stayed there for most of the night; he didn't sleep a wink last night. He mobilized the most skilled forensic investigators from the entire Nanchang Public Security Bureau, and they thoroughly investigated every detail of the crime scene.
Of the four victims, the elderly were all killed with a single stab wound. According to the forensic investigation, the perpetrator's attack was precise and ruthless, completely severing their carotid arteries. While the younger male victim showed signs of torture during interrogation, no valuable clues were found on his body; no skin flakes, hair, or fingerprints were discovered.
"The initial assessment is that there are two suspects, which can be determined from the unfamiliar footprints found at the scene. However, it is very likely that the two people covered their entire bodies when committing the crime and did not leave any biological traces at the scene."
With current case-handling capabilities and criminal investigation techniques, a thorough investigation of the crime scene can always uncover biological traces of the suspect's presence. Chen Jianguo's confidence in solving the case yesterday stemmed from the fact that collecting trace evidence at the scene and then analyzing it could potentially reveal the suspect's DNA.
To his surprise, the crime scene investigators searched the area several times but found no trace of a stranger. As for the young female victim, although there were signs of assault, her body had already been cleaned by Ji Xian, leaving no visible marks. This resulted in Chen Jianguo and his team making very little progress after a whole night.
How are your interpersonal relationships?
Qin Chuan asked.
"We have conducted a detailed investigation into the interpersonal relationships of the victim's family. We have found no one with whom the victim's family has any deep-seated hatred. Through interviews with neighbors, we found that the family is usually quite peaceful and honest. We have focused on investigating their personal interpersonal relationships."
This was something Qin Chuan had specifically instructed them to arrange yesterday. Therefore, Chen Jianguo deployed a considerable force, with four groups investigating the personal relationships of the four individuals. However, after an entire night of investigation, they discovered that the elderly members of the victim's family of four had virtually no social activities outside the home. The two elderly people didn't originally live in Nanchuan City; they were from Tianzhou City. They came to their son's place to help out at his wedding and had stayed for a while.
The two elderly people were not familiar with their neighbors or anyone else, and they rarely went out. Chen Jianguo even contacted the Tianzhou Public Security Bureau yesterday. The investigation results came back this morning: the two elderly people farmed more than 20 mu of land in their hometown, making a living by farming. They had good relationships with the villagers, and no one from their village had traveled far on the day of the incident.
In addition, the two elderly people did not have any overly complicated financial disputes.
"The young male victim worked for the sanitation department as a subcontractor."
The investigation into the young male victim has yielded some leads. He was somewhat withdrawn and quiet at work, and had recently had a physical altercation with a colleague. Last night, Chen Jianguo's team went to the sanitation bureau to investigate. The colleague with whom the victim had the altercation was their primary focus, but he was on duty at the time of the incident. The workplace has CCTV footage proving he did not leave, meaning he did not have the opportunity to commit the crime.
In addition, the young male victim also enjoyed playing mahjong.
“We investigated their usual mahjong games. At most, the winnings and losses in a game would be around one yuan, and the maximum amount involved would be a few dozen or a hundred yuan.”
"In addition, all those who frequently played mahjong with the young male victim have alibis."
"What about the female victim? How's the investigation into her interpersonal relationships going?"
Qin Chuan took the documents Chen Jianguo had brought. He found a few photos of the on-site investigation, picked up a ballpoint pen, and started writing something while listening to Chen Jianguo's report.
