The murderer was successfully brought to justice, but to be convicted, the murder weapon must be found.
In the next two days, the criminal team members turned Guo Fenglian's home upside down, but did not find anything suspected of being a murder weapon.
Following Guo Fenglian's arrest, it took nearly five days for several people to go from confidently searching for evidence to being frustrated when they couldn't find the evidence.
Without evidence, there is no way to finalize the case. Without any way to finalize the case, there is no way to prove that the murderer of the first two victims was Guo Fenglian.
In the past few days, the chat team has been as worried as a family funeral. The office is lifeless, and there is no personal atmosphere.
There is a large white table in the center of the office, which is filled with various analysis reports on Guo Fenglian.
Among them, there is no way to find a suitable reason for the reason for killing alone.
"From the surface, there is no grievance between Guo Fenglian and the two deceased people. Why did they want to kill people?" Li Dongliao's eyes turned black as he investigated.
He felt strange. In the past, it was difficult to solve the case and find the murderer. Now that the murderer has been arrested, it means that the answer has been announced. All he has to do is work backwards and verify. Why is it so difficult? ?
Based on the injuries of the two deceased persons, forensic doctor Lao Zhang speculated that they were machetes used for chopping meat. Judging from the length of the wounds, the blade must have been at least 30cm long.
There are also scratches on the deceased's mouth, which may have been caused by the murderer using some kind of metal fixator to fix the deceased's head.
A 30cm machete and a metal holder, these two items alone are not so easy to ignore.
Li Dongliao also looked at a month of surveillance near Guo Fenglian's house. During the murder, no large bags of garbage were thrown away, and the murder weapon was not taken out and discarded. This means that the murder weapon could not have been taken out of the house.
"It's really terrible, I'm going to hell!!" Li Dongliao became more and more irritable, "We finally caught the person, now if we can't find the murder weapon, we have to let him go!"
At this time, Tanwan received a call from the city's Traditional Chinese Medicine Hospital.
The call from the hospital was initially placed to the police station, and was later transferred to Tan Wan.
Tan Wan answered the phone with confusion: "Hello, this is Tan Wan."
The other end of the phone was the hospital's ICU emergency room. The doctor in the emergency room told Tan Wan that a patient who was on fire had just come to the hospital. After examination, he felt that the situation was a bit strange.
The doctor on the other side didn't make it clear. When Tan Wan asked what was strange, the doctor on the other side also gave a vague answer: "Officer, come here first. I'll explain it to you in detail when I get here."
Li Dongliao didn't know the truth. Watching Tan Wan pick up his bag and prepare to leave, he asked anxiously: "Where are you going?"
"Go to the hospital."
I drove to the city's Traditional Chinese Medicine Hospital and found the ICU emergency room with ease.
After explaining his purpose and identity, the security guard at the door of the emergency room led the person in: "Doctor Gu, the police you are looking for are here."
Dr. Gu is very young and looks like he has only been working in the hospital for a few years.
"You are Officer Tan, right?" Dr. Gu came forward and took Tan Wan to bed No. 3. "He is the patient I am talking about."
Looking in the direction of Dr. Gu, the person lying on the bed looked familiar. After a closer look, wasn't it the homeless man?
The homeless man who was originally wearing black rags now changed into clean blue and white striped clothes, his face was also cleaned, and Tan Wan almost didn't recognize him.
Tan Wan pointed to the unconscious homeless man on the hospital bed and asked, "What's wrong with him?"
"Two lower legs were severely burned, and the upper limbs and abdomen were also burned by the fire." Dr. Gu held up a case hanging at the foot of the homeless man's bed. "Fortunately, it was not far from the river when it happened. He fell into the river and was killed." People discovered it.”
When Dr. Gu lifted up a corner of the sheet to reveal the homeless man's ulcerated feet, a strong stench hit his face.
The surface of his calf was so ulcerated that it was hard to see clearly, and there were oyster shell-shaped blisters on it. There were seven or eight of these holes, about the size of a cherry, and they looked very scary.
"Don't be afraid, Miss Police Officer. This is called ecthyma, also called deep impetigo."
Dr. Gu introduced this disease in the evening. This disease is mostly caused by hemolytic streptococci. Poor sanitary conditions, malnutrition or physical weakness are the triggers for this disease.
However, this patient did not receive targeted treatment, which has led to the rapid development of skin lesions and the gradual emergence of necrotic ulcers. If left untreated, he will easily develop sepsis or die from pneumonia.
The reason why the hospital specifically called the police station is...
"When the patient was brought in, the burning substance on his legs stuck to his skin. We analyzed it and it looked like human bone powder, so..." Dr. Gu hinted with some taboo.
As we all know, bone mineral salts account for about 75% of human bones, of which 95% are calcium and phosphorus.
Some people have seen will-o'-the-wisps in the cemetery, and the so-called 'will-o'-the-wisp' is actually a kind of phosphorus fire, which is the result of a chemical reaction of gases produced by the decomposition of organisms.
Phosphorus has a very low ignition point and is extremely easy to burn, and the heat after combustion can reach 400-800 degrees.
Tan Wan looked at the homeless man lying on the hospital bed and fell into deep thought. The missing fragments in his mind were being pieced together bit by bit into a complete model.
When he realized that he might have found the wrong person, Tan Wan seemed to have fallen into a black hole of consciousness.
She frowned and opened and closed her lips slightly. She couldn't help being shocked by the thoughts in her head: "It's wrong, it's all wrong... It turns out that it's like this! Maybe it wasn't Guo Fenglian who killed... ..”
"What are you talking about, Miss Police Officer?"
Tan Wan seemed not to hear his question and asked directly: "Can he still live?"
"Okay, I'm still in a coma now. I'll wake up after the antibiotics enter my body."
After getting the accurate answer, Tan Wan felt a little calmer: "Thank you Doctor Gu, I have to go now."
Tanwan didn't wait for the doctor's response, picked up her bag, and left the emergency room with a solemn expression.
