"Xiao Ran, what did you find again?"

At the first scene, Zhang Lei looked at Xiao Ran, who was squatting on the ground and advancing inch by inch towards the periphery, and felt inexplicable.

The pavement here has been cleaned after the site survey, and it is even more difficult to find any useful traces at this time.

What's more, Zhang Lei didn't know what Xiao Ran was looking for, and he couldn't figure out what clues Xiao Ran had found.

Zhang Lei racked his brains, after all, he also knew the information about the case clearly, but was there anything wrong with it?

"Did you notice the Band-Aid on Zhang Cailiang's right index finger?"

Xiao Ran wore gloves, and after playing with a clump of weeds under his feet, he turned his head to look at Zhang Lei.

"Isn't it cut by peeling fruit?" Zhang Lei wondered.

Xiao Ran continued to squat on the ground and moved forward to search: "No, when he raised his hand, I saw the wound through the gap between his fingers and the band-aid. ”

"Huh?"

Zhang Lei reacted at this time and said in surprise: "Isn't it a neat cut wound?"

"Irregular triangular wounds. ”

Xiao Ran's tone was affirmative: "It should have been the plastic stab on his right small lamp shell." ”

"Are you sure?"

Zhang Lei stood up suddenly: "Then he is lying! There must be something wrong with the wound on his hand!"

"Otherwise?" Xiao Ran asked rhetorically.

"Then we should look for trace traces on the lamp shell of his motorcycle, why do you want to come here?" Zhang Lei was still a little confused.

"His motorcycle is clean, and you can't taste it even if you eat his lamp case. ”

Xiao Ran teased: "You didn't even see this detail as a technical detective?—— I think the wound on his hand should have been caused at the first scene." ”

Zhang Lei shrugged his shoulders and turned a blind eye to Xiao Ran's contempt: "Even if we were injured here, we really didn't find any suspicious bloodstains." ”

"It may be that the scope of the search is not large enough. ”

Xiao Ran's tone was weak, and he said again: "Maybe there is nothing left......

Time passed minute by minute, and before I knew it, most of the afternoon was almost gone.

With the location of the central blood pool as the center of the circle, Xiao Ran and Zhang Lei have touched every grain of earth, rock, and grass within a radius of 30 meters, but they still found nothing.

Zhang Lei was already lying on the ground and crawling forward at this time, squatting for an afternoon, Zhang Lei only felt that this was the longest afternoon in his life, and the posture he always maintained made him feel that his waist and legs were about to be broken.

Vehicles and pedestrians who came and went also noticed the two people who behaved strangely, and some curious people also took out their mobile phones to take a few small videos and sent them to a certain sound and a certain hand, and then note a UC title: Shocked, the performance art of the police in the new era!

There are even more people who don't know why they thought that there was something on the ground here, and they wanted to look for it with their heads bored, but they were chased away by Zhang Lei.

"Xiao Ran, I think it's better to go back, we've all found such a big place, and we haven't found a single hair!"

Zhang Lei stood up and rubbed his thighs, which were almost unconscious, and shouted at Xiao Ran: "Otherwise, let's let the Lei Brigade add a few people to come over and look for ...... together."

"Come here, camera!"

On the side of the road, nearly 50 meters south of the blood pool in the center, Xiao Ran finally made a discovery, only to see that on the back of a large-leaved grass, a drop of dried blood was so dazzling.

Xiao Ran observed the blade of grass and judged that this drop of blood should have dripped vertically, but because it was next to the edge of the leaf, it flowed along the edge of the leaf to the back, so that the traces left on the front were very small.

"What's going on? What's going on?"

Zhang Lei turned around and took out a SLR from his backpack, stiffened his legs and screamed, and ran to Xiao Ran's side with a jump.

"Did you see this drop of blood? Xiao Ran pointed to the blood spots on the leaves and said.

"There's a different drop of blood!"

Zhang Lei said in shock, he didn't dare to slack off, quickly adjusted the focus, and took a whole set of photos from various angles.

After Zhang Lei finished filming, Xiao Ran took out the small scissors and the physical evidence bag, and carefully cut off the blade of grass and put it into the bag.

"Immediately tell Team Lei and let him draw Zhang Cailiang's blood and compare it with this blood!"

Xiao Ran looked at the grass that was quietly curled up in the physical evidence belt, and was 80% sure that this drop of blood was Zhang Cailiang's.

As for Zhang Cailiang himself, Xiao Ran had already affirmed that he was extremely suspicious.

Quickly sent the blood sample to the forensic doctor to extract DNA, Xiao Ran told everyone his thoughts as they were: "Actually, I'm not sure if I can find blood droplets, I just want to give it a try." ”

"It's good, but if you have ideas in the future, you should say it in advance, don't hold it back. ”

Lei Kang praised Xiao Ran expressionlessly, although he and Xiao Ran are basically uncles and nephews, but work is work, only superiors and subordinates, and he is very clear.

"Your attempt may be a major breakthrough. ”

Pang Jinghui sat next to him, his mouth almost reaching the root of his ear.

He is an old cadre with a great sense of collective honor, and the captain of the first team didn't notice the wound in Zhang Cailiang's band-aid, but it was discovered by the little guy of their third team, so he became proud, and a few big words were clearly written on his face: Sorry, the third team has a long face again!

"Xiao Ran, do you want to come to our team? It's a pity that your talent can't come to our serious crime team, it's not challenging to deal with some sneaky cases every day. ”

Shao Yong looked at Xiao Ran, with a demagogic words and deeds, when Lei Kang just intercepted Xiao Ran from the hands of the Beijing Public Security Bureau, he wanted to ask Xiao Ran to his first team, but I don't know why, the Lei brigade just pressed Xiao Ran, a good seedling, into the third team.

At that time, he was still sighing, what a seedling, it's a pity......

"Hey, I said Lao Shao, where am I still sitting here, don't dig the foot of the wall with such a righteous light!"

Hearing Shao Yong say this, Pang Jinghui was immediately unhappy, our third team just had a calf, you guy wants to dig the foot of the wall, the first squadron is amazing!

As he was talking, the police from the local police station pushed the door in, "Report to Captain Lei, Zhang Cailiang's blood sample has been taken!"

Lei Kang stood up, his voice still low and powerful: "Send it to Forensic Doctor Xue immediately, extract DNA for comparison!"

At 9:30 p.m., news came from the bureau's forensic office that the DNA of the two blood samples had been compared, and the overlap between the two was 99.7%.

In other words, the blood droplets on the blades of grass near the scene were left by Zhang Cailiang!

And the wound on his hand was not cut by peeling fruit in the morning at all, but was punctured by a fragment of the headlight for some unknown reason on the night of the incident!

"Immediately detain Zhang Cailiang and bring him back to the bureau for surprise interrogation overnight!"

Lei Kang decisively ordered, and everyone who had been waiting for news in the conference room hurriedly took action and followed the police from the police station to Zhang Cailiang's home.

"Zhang Cailiang, because you are involved in a case, now go back with us for investigation. ”

Zhang Cailiang listened to the information of the comrades at the police station, and there was a hint of depression on his face, and he often sighed, and got into the police car with a calm expression......
