National Forensic Doctor-Chapter 1192 - 1122: Songxiang Park

That night, Jiang Yuan arrived in Luo Jin City on a business flight.

After resting for a few hours, at five o’clock the next morning, Jiang Yuan’s Cold Case Squad was loaded into several cars and rushed to Songxiang Park.

This community park is not very large, and the access control is certainly not strict, with four gates open in the east, west, north, and south. The walls are just symbolic brick fences slightly taller than a person. The ground parking lot is not small, everything is prioritized to serve the surrounding residents. The parking lot guard is the only park management personnel visitors can contact; the rest are nestled in a small building hidden by trees, working or not, no one knows.

Liu Wenkai looked at this small office building and the nearly deserted environment and couldn’t help but sigh, "Working in landscaping is really sweet, isn’t it like getting paid for nothing?"

"Everyone sells their time and labor, naturally there’s no difference!" retorted the sharp-tongued guide, Qiu Li, unabashedly countering Liu Wenkai.

Liu Wenkai smiled at her words, not feeling hurt in front of his colleagues but apologizing instead, "It’s my mistake. Kids of leaders do know how to talk."

He certainly wouldn’t say the same in Shannan Province because there people could easily hold you to account. But in Luo Jin City, it wasn’t much of an issue. In such a laid-back department, the kids doing the work are likely only mid-level—Liu Wenkai understood some officialdom reasoning.

The nose of the guiding girl, Qiu Li, wrinkled in annoyance, "Who said I’m a leader’s kid?"

"Are you not?" Liu Wenkai asked, feeling assured, and just smiled.

Qiu Li, wearing jeans, with long hair draped over her shoulders, her brows curved, gave him a nice glare, didn’t speak, and after a while said, "I got in by passing the civil service exam."

This time, Liu Wenkai just smiled and didn’t respond.

Upon pushing open the office door, the director of the park management office and several deputy directors were waiting inside.

Liu Wenkai skillfully made demands, noted phone numbers, confirmed contacts, retrieved surveillance videos, etc., all the work done. Then he headed with Qiu Li to the park site.

Qiu Li didn’t speak all the way. When they were almost there, she suddenly slowed her steps and asked, "Did someone really die in our park?"

"It’s unclear for now." Liu Wenkai wouldn’t leak information to her.

Qiu Li didn’t believe it, "You’ve brought dozens of people. If it’s unclear, why are so many people here, and you’re from another province. Is it someone from Shannan Province who died?"

She had only seen Liu Wenkai’s ID and didn’t know the background of the others.

Liu Wenkai just smiled gently, saying, "This park is so remote, surely a lot of people have died here. Did you ever see ghosts when you left work in the morning or evening?"

The girl’s eyes were clear and straightforward, asking innocently, "Why do you ask that?"

Liu Wenkai: "Have you ever heard of the Dragon Team?"

...

Jiang Yuan, wearing shoe covers, a mask, a hood, and gloves, walked around a lawn filled with dog poop, feeling that the dogs around seemed to be hostile towards him.

The police cordon was drawn very large, enclosing the entire clover lawn within it, something not typical for ordinary murder scenes. But with Jiang Yuan involved in the case, the Luo Jin City Criminal Police Detachment dared not be negligent at all.

In contrast, the dogs waiting outside the lawn were puzzled and angry; those particular ones were trembling at the legs now.

An area meant for a good poop shouldn’t be off-limits.

"The scene is probably around here." Jiang Yuan came to a dense bush and drew a small circle in front of him. "A large area of clover, a small amount of anemophilous plants, and dense shrubs on the right side can significantly isolate the pollen from flowers like roses nearby. Going further forward, the amount of rose pollen increases..."

Qiao Shengli was also dressed up, watching in front. As she listened to Jiang Yuan, she checked both the park map and the scene, admiringly saying, "I didn’t consider this patch of shrubs..."

"Because the spore-pollen spectrum is definite, you just need to find a match." Jiang Yuan said as he explained several specific plans to Qiao Shengli.

Qiao Shengli’s dissertation was almost done, and she had published two papers in top journals. Listening to case details was futile, but hearing forensic botany’s specialized content filled her with enthusiasm.

At this moment, the young lady from the park management office also came over, seeing a man and a woman on the lawn from afar.

The intellectual beauty with long, straight black hair instantly caught young girl Qiu Li’s attention. She first looked at her own feet, then couldn’t help but look at the lawn, saying, "Who are those two? That woman’s eyes are practically dripping with admiration."

"The woman is a female Ph.D. student, the man is Doctor Jiang." Liu Wenkai said, gesturing with his lips, "Put on shoe covers first; we’ll go over to say hello to Captain Jiang and see if there are any park issues to ask you."

"Okay." Qiu Li nodded without hesitation, dressing properly, then bravely walked towards the two people on the lawn.

Liu Wenkai sensed something was wrong, gave Qiu Li a curious look, and said, "At times like this, shouldn’t you be backing out?"

```

The newly appointed civil servant Qiu Li glanced at Liu Wenkai with the corner of his eye and said, "I prefer tall ones."

The middle-aged official Liu Wenkai looked at Qiu Li in surprise, "But... shouldn’t you ask if Captain Jiang is seeing anyone?"

"I’ve already spotted a competitor. What’s one more?" said Qiu Li, swiftly dressing and stepping onto the lawn.

The approaching figure immediately caught Qiao Shengli’s attention.

Qiao Shengli and Qiu Li locked eyes, both becoming serious.

At this moment, Jiang Yuan’s voice came, "Everyone step off the lawn. We need to conduct a thorough investigation here to see if we can find any clues related to the victim."

"Aren’t there any bloodstains or anything?" asked Liu Wenkai, oblivious to Qiu Li, his expression becoming serious. Having worked on many cases, he was somewhat familiar with legal botany now and knew that pollen maps could prove the victim once lay on this lawn but did not necessarily mean they were killed here.

Of course, with the victim’s time of death considered, the likelihood of being killed in the park was high, but it was also possible that they fell here or were simply engaged in a wild battle, only to be murdered elsewhere shortly afterward.

Thinking of wild battles, Liu Wenkai couldn’t help but scan the surroundings, his brow furrowing in thought.

Jiang Yuan was similarly deep in thought and said, "The victim’s body is quite decomposed, but from the current analysis, when the victim was killed, there may not have been a lot of blood. Additionally, due to the passage of time, even if there were small amounts of blood stain, they might have decomposed."

The almost invincible Luminal and other reagents depicted in TV shows work best inside man-made structures. Because artificial buildings lack natural decomposers, bloodstains and such can persist for long periods—even decades—despite using high concentrations of cleaning agents, they might not be entirely cleaned.

The real nature hardly needs cleaning agents.

For thousands, tens of thousands, millions of years, countless bodies have perished in nature, many with larger body sizes and bone densities than humans, yet none of their flesh remains.

Even in agricultural fields, bones will gradually decompose if left unattended, and those burial mounds at the edge of fields will be largely vanished after three generations unless maintained.

While the park isn’t quite as strong, the grass rich with dog feces has nurtured many decomposers. If the victim’s bleeding wasn’t significant, a few days would suffice.

Moreover, the grassland with abundant organic matter has very chaotic DNA, and finding even a trace amid such large areas is incredibly challenging without solid evidence.

"Doesn’t that mean it was a futile trip?" Liu Wenkai thought about the private jet they took together, feeling somewhat uneasy.

Jiang Yuan operated Level 5 Crime Scene Investigation, calmly stating, "Let’s take samples first and then examine the surroundings."

A crime scene isn’t just a murder site; the suspect’s entry routes, and any changes in the surrounding environment, are part of the crime scene. Police daily investigations inevitably involve these aspects.

Liu Wenkai was somewhat worried due to emotional attachment, mainly because it’s not his specialty.

Jiang Yuan said nothing, and together with his younger trainee and another forensic technician from Luo Jin City began walking around the park.

Near the lawn, besides Luo Jin City’s Pang Jidong and Director Xu, Ningtai’s Huang Qiangmin and Lanyue’s Jian Louyuan were also present.

Everyone’s expression was particularly solemn.

This case has essentially become a collaborative effort among three provinces, and for a disciplined force like the police, honor is always paramount.

A force driven by money will never surpass one fueled by honor—because human needs are infinite while material resources are limited, only spiritual honor can perfectly match human spiritual needs.

No matter how much money is given, there will always be times when it’s insufficient; even with a lot of money, when lives are at stake, anyone would hesitate. Only honor can drive people to sacrifice fearlessly.

Thus, disciplined forces constantly prioritize honor.

This case, moreover, has tightened the strings for the three provinces’ teams.

Qiu Li sensed the atmosphere, and his body, accustomed to the leisurely department, suddenly became excited, instinctively following behind Jiang Yuan.

"There aren’t many cameras in the park, and their positioning is quite average. Yet, the perpetrator avoiding all cameras shows certain professionalism," said Jiang Yuan—Level 3 Technical Surveillance & Level 6 Image Investigation Trajectory Analysis.

"There’s no personnel guarding the park entrances, and the camera at the east gate is crooked, but they likely didn’t use the east gate. The surrounding walls are quite low, with fences built on brick structures—the bricks can be stepped on, and the fence is damaged... Considering the perpetrator could transport the body over 300 meters, climbing over this fence shouldn’t be difficult." Jiang Yuan—Level 4 Brick Laying & Level 4 Forensic Material Evidence & Level 5 Crime Scene Investigation.

"The routes within the park are rather concealed, and there aren’t many people around. If dealing with a body, there should be many places in the park to consider—transporting it out isn’t hard, but it also indicates a strong motive from the perpetrator." Jiang Yuan—Level 2 Pathfinding in the Woods.

As Jiang Yuan spoke, Wang Chuanxing took notes beside him.

Qiao Shengli and Qiu Li stood to the left and right, listening to Jiang Yuan’s assured tone, their eyes shining brightly as they followed him, while each also observed the other with suspicion.
