Here, it was the stage where the suspect performed, and at this time, Lu Zhu was like a substitute, repeating those actions on the stage after his performance.

Then, Lu Zhu lay on the cold ground again, the soil still had Zhang Jimin's blood in it, Lu Zhu took a deep breath, and there was still a trace of fishy sweetness in the air.

"This murderer is very sophisticated, and his methods are very simple. He should be between 1.75 and 1.80 meters tall, weigh around 65 kilograms, and may have suffered a minor injury to his left leg. Lu Zhu pointed to another shoe print on the ground, and Fang Lubai also glanced closer.

These are similar to Fang Lubai's judgment, the deceased died due to mechanical suffocation and insufficient blood supply, and the arm of his left hand should have been separated before he died, and Zhang Jimin was very likely to watch the murderer disassemble his arm from the sidelines.

Even Fang Lubai, who has solved many major murder cases, has goosebumps all over his body at this time. How strong is the psychological quality of this criminal suspect, who can be so strong that he can unload people alive.

Then Lu Zhu leaned into a shoe print and sniffed it carefully, and then he excitedly motioned to Fang Lubai to smell it too.

Fang Lubai didn't make it so troublesome, he directly grabbed a handful of dirt from the depths of the footprints, put it on the tip of his nose and smelled it, but except for the faint smell of blood, he couldn't smell anything else.

Lu Zhu saw Fang Lubai's confused look, and he also shook his shoulder: "Didn't you smell the smell of pig dung in the lines of the shoe prints?" ”

Fang Lubai only reacted at this time, it turned out that the fishy smell did not come from Zhang Jimin's blood, but was stained on the sole of his shoe and stepped into the dirt there.

Zhang Jimin should have had his left arm cut open first, and about a few hours later, the suspect spoke to Wu Wenhui and said that he had changed the mystery.

"The most terrifying thing about this should be that Zhang Jimin was sawed off his other arm before he died." Lu Zhu pointed to the pool of blood on the ground that had almost dried up, and he shivered all over.

"There's a suspicion here, the blood here is obviously not dry yet, and according to the speed at which the blood touches the dry soil, the soil here shouldn't be so wet at this time." Fang Lubai grabbed a handful of dirt in the pit and easily kneaded it into a ball in his hand.

"The reason why the soil can still be so wet is mostly related to the weather, the temperature difference between day and night in Tianhai City is large, and dew is easy to appear in the middle of the night, but the most important thing is perhaps because of this."

Lu Zhu took the blood-stained mud ball in his hand, and picked out a small green leaf from the pile of mud.

Fang Lubai carefully put it in his hand, and found that it was a small piece of spinach, so he also suddenly realized.

"The suspect removed Zhang Jimin's left arm before, and there should be a loud noise, but no one reported the case, which means that there are two possibilities, one is that there are sounds around that can perfectly cover up Zhang Jimin's voice."

"And what could the second one be?" Seeing that the two were talking hotly, Gu Na also interjected a sentence in the middle.

"The second possibility is that Zhang Jimin himself can't shout!" Fang Lubai looked at Lu Zhu and praised his judgment ability.

At this moment, Wu Wenhui's mobile phone rang, and when he looked at the number, it turned out to be Saturday, Wu Wenhui hurriedly turned the mobile phone to the outside, and everyone listened carefully.

"Wu Bureau, the deceased is the youngest policeman, I won't say the name and gender, I'll say something useful next."

Fang Lubai and Lu Zhu hurriedly urged Saturday to continue, so Saturday also said without delay: "The cause of death of the deceased was mechanical suffocation, death caused by excessive accumulation of carbon dioxide due to lack of oxygen in the body. The corpse spots are just beginning to appear, and I can't predict the exact time in the car, but I can only roughly judge that the deceased died no more than three hours ago. The murder weapon should be a cable or a piece of hemp rope, but it is impossible to determine what it is, because the suspect should have wrapped the murder weapon with something before he did it, and the wrapped thing was likely to be a plastic bag, because there were obvious blue plastic particles around the neck of the deceased. ”

"I have checked the inside of Zhang Jimin's mouth, his tongue has been cut off by the roots, and there are several obvious knife marks on the outer wall of his lips. Moreover, the suspect was more sophisticated, and when cutting the arm of his right hand, he avoided the thickest tendon there and cut off that arm. ”

Fang Lubai also listened carefully, these clues are very important, at least for the clueless SCI team, every sentence may play a crucial role.

"For the rest, I can only go to Tianhai Medical University for dissection, and I will report to you in an hour." With a whistle, the other end of the phone also hung up.

Fang Lubai was very interested in that crime tool, although things like letter openers are very common in Tianhai City, but in the countryside here, every household uses ordinary kraft paper envelopes, and absolutely few people will use tools like letter-opening knives. In this way, there are big doubts about the origin of the suspect, and he chose to commit these two murders here. Obviously intentional!

Fang Lubai walked back to the car, also holding a notebook in his hand, sitting at the door alone, and began to speculate.

I saw him sketch a few strokes on the notebook, and then the shape of a human face appeared. Then he began to depict the details again, and after a while, a perfect sketch was sent to Lu Zhu's hands.

Lu Zhu held the sketchpad in his hand, thought carefully for a long time, and finally made a suggestion like Fang Lubai: "I think his shoulders should be offset to the right side, because all his footprints are biased towards the force of his right foot, and he also deliberately wears a pair of shoes two sizes larger, his height should not exceed one meter seventy-five, and he seems to have a mental cleanliness, so his hair will not be so long, it will only be short." After saying that, he gestured his hand on his head so that Fang Lubai could figure out how long his hair was. After listening, Fang Lubai felt that it made sense, and raised his pen to revise it.

Fang Lubai glanced at Chang Qingshan and took the portrait in his hand: "Do you remember the reasoning that the two of us did in the online field last time?" Both of us thought that the murderer was about 1.85 meters tall and strong, but this time Lu Zhu and I came to the conclusion that the murderer was about 1.75 meters tall, thin, and his left leg seemed to have been injured. ”
