You're supposed to be a security officer, what case are you solving?

Chapter 48 Usurping the Nest!

June 15th.

The day after the incident, at 2 PM.

Yang Jinwen parked his tricycle in Wutong Lane, got off, and spat out the mud and sand that had been blown into his mouth.

Zheng Kang didn't wait for him and went straight into the alley.

Compared to yesterday, the alley was much quieter, but passersby knew that a murder had occurred at number 11, so they frequently peered into the police cordon in front of the door.

After finishing his meeting, Ma Boming rushed to the scene. He had no choice but to come because he had to accompany the experts from the Municipal Bureau to conduct a re-examination and search for any missing physical evidence.

To Yang Jinwen's surprise, Liao Guohua from the Chengnan Branch was also at the scene. He was standing at the door with two other people, trying to reconstruct the entire crime scene.

Zheng Kang immediately flew into a rage.

He quickened his pace, came up behind Liao Guohua, and shouted at the top of his lungs, "Captain Liao, have you crossed the line?"

Liao Guohua quickly turned around, feigning surprise, and patted his chest: "Who do we have here? It's Lao Zheng! You scared me! Don't you walk quietly?"

Zheng Kang didn't give him any face and asked directly, "Captain Liao, this is a case from our North City Branch!"

"What's with all this distinction between the north and south of the city?" Liao Guohua laughed. "They've even set up a special task force. Besides, your North City Branch has such a low case-solving rate that the Municipal Bureau has to rely on our South City Branch and Jiaxing Branch to save face. This case, isn't it all thanks to our help?"

Zheng Kang's face turned ashen. He gritted his teeth and replied, "We don't need your help with this case. We can catch the person ourselves."

Liao Guohua chuckled and spread his hands: "Old Zheng, you're usually quite steady, unlike He Jinbo who talks big but doesn't. Don't talk big, this is a murder case."

What about the Municipal Bureau? Don't you need technical support from the Municipal Bureau either?

"Municipal Bureau..."

Zheng Kang was about to retort, but Yang Jinwen tugged at his arm from behind.

Zheng Kang turned to look at him and saw Yang Guochang and Wen Mo from the Municipal Bureau standing inside the door, squinting at him.

Without a doubt, Liao Guohua was trying to entice Zheng Kang to speak ill of the Municipal Bureau.

Zheng Kang nodded to the two municipal bureau leaders, swallowed his words, and glared at Liao Guohua, as if to say: We'll see.

Liao Guohua ignored him and instead spoke to the two leaders with a fawning expression: "Director Yang, Captain Wen, we have roughly figured out the situation."

Wen Mo glanced at Yang Jinwen's face, then turned his gaze to her and asked, "Captain Liao, what do you think?"

Liao Guohua took two steps back and pointed to the alley entrance: "It's only about 100 meters from that end. Based on the estimated time of death, the incident should have occurred around 2 a.m.

According to forensic expert Wen, there were at least two perpetrators, and these two individuals must have carried tools; in addition to the murder weapon, they must have also used at least a crowbar.

Liao Guohua walked to the door, reached out and pulled it closed. There were obvious signs of damage to the padlock. Because it was a wooden door, there were pry marks on the edges, and small splinters were sticking out from the edges.

"Look here, is this the case?" Liao Guohua pointed to the wooden splinter and pushed the door in. The latch on the back of the door against the wall was deformed.

Yang Guochang pondered for a moment and said, "A crowbar? What kind of crowbar?"

Liao Guohua chuckled: "I'll have the city bureau's technical team come over and take a look later, Director Yang. Anyway, I'm pretty sure the criminals came prepared..."

Before he could finish speaking, Zheng Kang squeezed past him, saying impatiently, "Make way."

After he finished speaking, he turned to Yang Jinwen and said, "What are you standing there for? Come here."

Yang Jinwen nodded, holding a pen and notebook in his hand, gave a slight nod to the two municipal bureau officials, and stepped into the dark main room.

"How rude!" Liao Guohua's sarcastic voice came from behind them. Zheng Kang ignored him and instead spoke to Yang Jinwen, "You spent the whole day at the scene yesterday. What did you find out? Tell me."

Yang Jinwen shook his head: "Master, I can only be sure of one thing, it wasn't an acquaintance who committed the crime."

"Isn't that obvious?" Zheng Kang was seething with anger, and his tone was anything but polite.

There are two things that I care about.

"What is it?"

Yang Jinwen opened the notebook and handed it to him.

Zheng Kang glanced at Liao Guohua, who was eloquently recounting the scene to the city bureau leaders, then quickly turned around and held his notebook to his abdomen, examining it closely.

Seeing his actions, Yang Jinwen whispered, "I looked at it carefully yesterday. The crowbar that Captain Liao mentioned is this kind of flat iron bar or steel bar."

The notebook contained a pencil drawing of this crowbar.

"Judging from the damage to the door and the degree of force applied, the crowbar used by the perpetrator should be about one meter long."

Zheng Kang squinted and pondered, "Are you sure it was this kind of crowbar that pried the door open?"

Yang Jinwen nodded: "I asked Sun Lu, and their door was tightly sealed. To insert a crowbar into the gap, and the murderer only needed two strokes to pry the door open, it's 90% likely to be one of these flat-ended crowbars."

Zheng Kang pondered, "I've seen this kind of thing before. It's usually used on construction sites or in the decoration industry. Stonemasons in rural areas also use this kind of crowbar when building houses."

After he finished speaking, he added, "But are you sure it's one meter? These crowbars are all over one meter long, close to two meters, so they're easier to use."

Yang Jinwen replied, "I tend to think it was no more than one meter long. The murderer must have sawed the crowbar in half before committing the crime, so that it would be easy to carry and not conspicuous."

Zheng Kang looked at him: "Didn't you tell Captain He about this?"

Yang Jinwen shook his head, then nodded: "Captain Ma knows. I discussed it with him yesterday. Captain He is too anxious; he only wants to use the bank as a lead to arrest people."

"anything else?"

Yang Jinwen pulled out two photos from his notebook: "Can you tell anything from the marks on Zhang Xiaoying's wrists?"

Zheng Kang held the corner of the photo and examined it carefully. It was obvious that when the murderer tied Zhang Xiaoying up, the rope had been wrapped around her wrists several times. Some marks were clear, while others were blurry.

Zheng Kang asked, "These are the photos you developed after spending the whole night in Old Ma's darkroom yesterday?"

Yang Jinwen raised an eyebrow, wondering how Zheng Kang knew about this.

Either it was Maozi who told the story, or it was Ma Boming; those two are the most gossipy.

Yang Jinwen nodded and asked, "Master, didn't you notice that the murderer's method of tying the rope was very professional?"

Zheng Kang's expression turned serious. He looked again at the marks on Zhang Xiaoying's wrists, then raised his face and asked, "Wasn't it just haphazardly tied up?"

Just as Yang Jinwen was about to answer, Zheng Kang made a shushing gesture.

At this moment, Liao Guohua, accompanied by two leaders from the Municipal Bureau, arrived at the door of Zhang Xiaoying's bedroom.

The municipal bureau experts, dressed in white coats, were meticulously searching for physical evidence, while someone held the municipal bureau's technical team's treasured multi-band investigation light in their hand.

Yang Jinwen's pupils were filled with green fluorescence!
