In order to confirm that there was a third party at the scene, Xu Hanlin drove to the exterior of Building 201, Building 1, Kunza Tuen Uk District, Kowloon District.

Two military officers stood outside the cordon, leaning sideways against the wall and chatting.

"Ayi, I heard that the champion of this IPSC extreme shooting sport can get a million-Hong Kong dollar prize, have you signed up?" asked a uniformed police officer, turning his head.

"My shooting level is also at the bottom. Police Officer Ayi laughed at himself that IPSC extreme shooting sports require accuracy, firepower, and speed.

He can only achieve two at the moment, either precision and firepower, or precision and speed.

"It's about participation, isn't it, saying that if you make it to the finals, you can also ask for advice and learn from the shooting masters of the Xiangjiang Gun Club. "Police officer Ah Xing agitated this.

"Forget it, forget it, if you have that kung fu to ask the master of the gun club for advice, it is better to ask for advice from Xu Sir in a serious case. ”

"You're talking about Senior Inspector Xu Hanlin of the Serious Crime Unit, Xu sir?"

"Uh-huh!"

When the two uniformed police officers were talking about Xu Hanlin without a word, he was carrying two supper, stepping on the stairs, and his leather shoes rubbed against the stairs to make a "da-da-da" footsteps.

"Sir Xu!"

"The two senior brothers have worked hard!"

"Thank you, Sir Xu!"

Xu Hanlin handed the two supper to the two police officers, and just crossed the cordon when police officer Ayi said, "Xu sir, have you signed up for this year's IPSC Extreme Shooting Event? ”

"Look, if I don't have a case at hand by then, I'll sign up. ”

Xu Hanlin replied that although the IPSC event was held by the Xiangjiang Gun Club, it was also under the supervision of the Xiangjiang Police Force, and the fact that there were police officers who could win the IPSC championship would also help them to be promoted.

After all, the Xiangjiang Police Force not only depends on academic qualifications, but also attaches more importance to personal comprehensive ability, which is why in many TVB TV dramas, many police officers, inspectors, and superintendents use their spare time to study or obtain other professional certificates.

At the same time, in the office area of the Forensic Science Section of the annex building of the Police Headquarters Building, Fang Xianlin was conducting laboratory tests and comparisons on the collection of blood and other physical evidence.

"Maadam, the autopsy report is out. A colleague from the appraisal department came over and handed the appraisal report to Fang Xianlin.

Fang Xianlin opened the appraisal report, turned to the column of the cause of death of the deceased, and saw that when the deceased secreted a large amount of adrenaline, the calcium ion channel of the heart was opened.

As a result, calcium ions enter the heart muscle cells, causing the heart muscle to contract strongly. During the reaction, calcium ions continue to rush in, causing the heart muscle to be unable to relax.

When a large amount of adrenaline reaches the heart, it produces an arrhythmia called "ventricular fibrillation," a heartbeat that causes the heart to tremble and unable to maintain the rhythm it should have......

"So, is it true that the deceased died because of brain death caused by lack of oxygen to the brain, followed by cardiac arrest and loss of vital signs, not by a sharp weapon piercing the heart and dying?" Fang Xianlin frowned,

"Yes!"

"Ah Xin, how long does it take for a person to lose his vital signs, and piercing the blood vessels in the body with a sharp weapon will not form a blood splash?"

After pondering for a moment, Ah Xin said uncertainly, "Under normal circumstances, after cardiac arrest, the blood stops flowing at the same time, and in this case, there is a possibility of blood splattering in 1-3 minutes. ”

Getting this answer, Fang Xianlin secretly analyzed, that is, within 1 to 3 minutes of the death of the deceased, the murderer used a sharp weapon to pierce the heart through the second rib, falsified the scene of the robbery and murder, and deliberately misled the police.

Ah Xin continued, "By the way, madma fang, the colorless crystals you asked me to test are out. ”

"What chemical composition does it contain?" Fang Xianlin hurriedly asked.

"Wait!"

Ah Xin opened the folder, took out a firm report, looked at it, handed it over, and said, "Aluminum potassium sulfate dodecahydrate;Kalinite (potassium aluminum sulfate dodecahydrate)......"

Fang Xianlin's result appraisal report was opened and looked at.

Name: Potassium aluminum sulfate dodecahydrate;

Abbreviation: alum

Chemical Formula: KAl(SO??)??· 12H?? O

……

……

After reading the appraisal, she looked confused, alum is now a food additive prohibited by law, and what is the purpose of storing dozens of kilograms of alum in the deceased's home?

At this time, an intellectual woman wearing glasses and a white coat knocked on the door and walked in.

"Maadam Fang, the results of the rose red pills you asked me to test are out. As he spoke, he handed her the appraisal report over and continued, "Although the appearance of this pill is like Magu, after careful analysis and comparison, the composition of this pill is consistent with that of multi-enzyme tablets. ”

……

Xu Hanlin stood in Room 201, Building 1, Kunzai Tuen Estate, closed his eyes and tried to deduce the size and height of the third party through the reenactment of the case.

However, the case reenactment skill did not analyze any information about the third party.

Looking at this, he knew that the skill could not be analyzed because there were too few known clues.

"Jingle Bell ......"

At this time, the mobile phone rang, and he answered the phone and heard Fang Xianlin's voice coming out, "Sir Xu, the autopsy report is out......"

Xu Hanlin hurriedly asked, "Deceased, what is the cause of death?"

On the other end of the phone, Fang Xianlin concisely told Xu Hanlin the cause of death, and also briefly mentioned the alum and multi-enzyme tablet test reports.

"Madma, you wait for me for 1 hour, I'll come and get the autopsy report now. ”

"Sir Xu, it's almost early in the morning, can't you come back early tomorrow morning to get the autopsy report?" Fang Xianlin complained a little tiredly.

Belch!

Xu Hanlin raised his hand to look at the time, and at 11:50 in the evening, he smiled and said, "I'm sorry, I forget the time when I'm busy with work."

So, tomorrow morning, I'll have the guy come and get the autopsy report and other reports. ”

Hanging up the phone, Xu Hanlin drove back to Shiya Garden, stood at the door of Room 1505, Block C1, opened the door with the key, and the house was pitch black.

Eh, it seems that Huya Mei's case is also very tricky, otherwise she wouldn't have gotten off work at this point.

After Xu Hanlin sighed, he walked into the open kitchen, washed a small bowl of fragrant rice and put it in the rice cooker, opened the refrigerator to thaw some seafood and put it in the rice cooker and set a time to cook porridge.

Subsequently, he edited a text message to Murong Xia and instructed him to go to the identification department tomorrow to get the autopsy report before coming to the police station.

The next day, in a rush of alarms, Xu Hanlin squinted his eyes and reached out to pick up his watch and looked at the time: 7 o'clock in the morning.

He continued to squint for about ten minutes, got up to wash, drank a bowl of seafood and vegetable porridge, and drove to the large open office of Group D of the serious case.

"Sir Xu is early!"

Niu Ben, Li Tiantian and other police officers got up and said hello.

"Good morning, everyone!"

After Xu Hanlin nodded in response, he asked Niu Ben, "Ah Xia came back and asked him to come directly to my office......

Before the word 'room' could be spoken, Murong Xia was out of breath, walked in three steps and two steps, and handed the autopsy report and several other identification reports to Xu Hanlin.

"Xu sir, according to the autopsy report, ......"

Xu Hanlin waved his hand to interrupt Murong Xia's words and said, "I already know the cause of the deceased's death. ”

Then, he clapped his palms, and after everyone put down their work and turned their eyes to themselves, "Ah Xia, Ah Niu, you two will lead people to expand the scope of investigation, and focus on investigating people who are familiar with the deceased and whose financial situation has suddenly improved in the past half a year." ”

"Sir Xu!" Li Tiantian continued, "The key investigation object you mentioned was accidentally found when I was investigating the financial situation of the deceased. ”

"Who is it?"

Xu Hanlin asked.

"I don't know his name, but I know that he lives next door to the deceased, and his surname is Wang!"

Li Tiantian explained that she learned about this situation because when she was investigating the deceased's financial situation, she met Lao Wang next door at the bank and checked it easily......

"The old king next door?"
