Ding Jiu took a deep breath, calmed down his mood first, and surveyed the entire room first anyway to see if there were any other clues.

He walked slowly around the pool of blood, and when he looked closely, he found a rather large footprint on the edge, which was a barefoot blood footprint.

Ding Jiu measured it with a tape measure, judging from the entire foot length, the foot that left traces was more than fifty yards, and the owner of the footprints should be a man, two meters tall, and even taller than Yao Ming.

And then observe the squeezing of the blood in the footprint and the ratio of foot width to foot length, the person should be extremely strong.

He calculated, if special circumstances are excluded, he is more than two meters tall and strong, and he can't weigh three hundred pounds.

Ding Jiu couldn't help but gasp, this person is taller and stronger than O'Neill, if he takes a punch, Ding Jiu can fly out more than ten meters.

Dan Ding Jiu continued to look closely, but found two things wrong.

For one, there are no papillae lines at the base of the footprint, only a few plantar folds.

The mastoid lines are actually the lines on the skin, and the mastoid lines on the hands are fingerprints.

And the other thing that Ding Jiu noticed was even more weird, making his hairs stand on end.

That is, this footprint is not visible at all, the footprint scars, the focus point and the pedal marks.

This explanation may be a bit too professional, in layman's terms, that is, when a person's foot steps on the ground and then lifts forward, there is always a place on the sole of the foot that is the most stressed, and generally the extrusion of this point is the most obvious, and the traces will be blurred.

As we get older, the focus of the footprint scars will also change, young people will be inside, and the elderly will be outside, but no matter how it changes, the posture of walking and the soft soles of the feet determine that the individual will definitely have the focus of the scars.

A person without mastoid patterns can be explained by walking barefoot, but there is no footprint focus...... That's there, and there's only one explanation—

Unless the owner of this footprint is not human!

All the traces of this footprint are on a flat surface, as if they were like iron plates falling straight to the ground, and jumping straight off the ground, which is by no means a human action.

Ding Jiu thought of this, and his mind replayed the zombie movies he had watched before, and he felt a chill on his spine, and he couldn't help praying in his heart, don't do what he thought.

With this footprint alone, Ding Jiu's trip was not in vain, but it was not enough, what Ding Jiu was looking for was a living evil cultivator, not a zombie.

Ding Jiu looked back and forth at other traces in the room, and there were traces of magnetic powder painting on various doorknobs, table corners, quilts, and other places that were easy to touch, but no useful fingerprints appeared.

The rest of the room doesn't seem to have many clues to be searched.

Ding Jiu walked around the house, and then returned to the door, Li Guang stood outside the door and said, "We have already surveyed everything we want to investigate, and there is no other trace except for that footprint." ”

Ding Jiu heard Li Guang say this, touched his chin, and suddenly said, "Brother Li, can I pull the curtains in the room?" ”

"Yes, yes. But there shouldn't be any marks on the curtains, right? Li Guang wondered.

Ding Jiu smiled and didn't speak, but just reflexively took a few steps to close the curtain, and then motioned to Li Guang to close the door as well.

Although Li Guang was puzzled, he also obediently did so, as long as Ding Jiu didn't destroy the scene, he didn't care what Ding Jiu did.

The room turned from bright to dark, the sunlight could only dimly shine through the thick curtains, the vision suddenly turned black, and there was a fishy smell under his nose, Li Guang couldn't help but rub his nose.

Suddenly, a beam of light lit up, shining on the blackened bloodstains, and the whole room seemed to be left with only this puddle of rotten blood on the floor, which made people feel a little nervous.

The beam moved, Ding Jiu almost put the flashlight on the ground, the beam was almost parallel to the ground, and he kept hunching over and walking around the room, as if he was looking for something.

Suddenly, Ding Jiu stood on the opposite side of the barefoot footprint in the pool of blood, and lay down to observe carefully, Li Guang took a few steps forward, wanting to see what Ding Jiu was looking at.

When he got closer, Li Guang found that under the illumination of the flashlight, a string of light dust and shoe footprints appeared, and several of them were clearly visible, which could be identified.

"Brother Li, do we have an electrostatic adsorption film in the on-site investigation box?"

Li Guangwei was puzzled: "This equipment for electrostatic adsorption and dust extraction is not cheap, and it cannot be equipped with every on-site investigation box. ”

Ding Jiu also frowned, usually in school, they didn't feel expensive when they had one hand, but now they had to take pictures to fix it and observe it on the spot.

Ding Jiu pouted his butt and carefully looked at the characteristics of the foot length and width of the dust footprints, as well as the characteristics of pedal marks and tread marks.

There is no doubt that the owner of this series of footprints is a person, Ding Jiu sighed helplessly, when he observed the footprints in the past, where would he tell if it was a person or not, and said to Hu Mengxiang that he was here for a long insight, but this time it was really a long insight.

The man should be in his thirties and forties, around 170 to 180 tall, and on the thin side, with a pattern on the soles that look like a pair of cloth shoes.

It is not necessarily 100% accurate to determine a person's height and posture by just relying on a footprint, but Ding Jiu is seventy percent sure.

Li Guang next to him said excitedly: "Ah Jiu, it's okay, you can find new traces at a glance, it is worthy of being professional!" Let's call Brother Hu quickly. ”

Ding Jiu smiled and nodded.

He let out a sigh of relief, and finally scratched a brow......

…………

It didn't take long for Hu Mengxiang to come to Chenguang Community with the people and equipment from the technical room.

Several people used Ding Jiu's method to successfully extract several more dust footprints.

Hu Mengxiang praised Ding Jiu's good professional skills, and at the same time expressed his admiration for the Criminal Police Academy.

"Master Hu, I want to tell you something."

"Say!" Hu Mengxiang said happily.

Ding Jiu scratched his head and said: "I want to follow this case, after all, this is the first time I have independently found a trace, and I want to see how useful this trace I found can be in the end." ”

Hu Mengxiang listened to the words and thought about it for a while, so he happily agreed, and it was not too much for Ding Jiu to ask for it.

The group surveyed the scene again, but there were no more valuable and overlooked clues, so they returned to the criminal police team.

When he arrived at the team, Hu Mengxiang asked Ding Jiu to take the trace evidence and go directly to find Thunderbolt, although Ding Jiu was stunned, he couldn't help it, so he still knocked on Qin Ming's office.

Qin Ming sat behind the table, took the physical evidence handed to him by Ding Jiu, looked down for a few minutes, and then looked up at Ding Jiu again.

Ding Jiu stood with his hands tied in front of the table.

He now had a feeling that he was possessed by Chen San.

Qin Ming nodded and said in a deep voice: "I didn't expect your ability to be good, I thought that the Criminal Police Academy was like Zhang Dahai." ”

Ding Jiu couldn't help twitching the corners of his mouth after hearing this, this fat man was black at school again.

"First the body was found, and now new traces have been investigated, which has made a breakthrough in the case, and the performance is good and worthy of praise.

To be honest, it was a bit surprising to me, and I didn't think anyone who could do things like that would be able to pay for couriers. ”

The corners of Ding Jiu's mouth twitched again, yes, he himself had blackened the school, he hurriedly apologized to Qin Ming, and said that he would repay the postage he had paid in advance.

At the same time, he said in his heart that when he came to Yuhang City in the future, he must go to the City God Temple to ask, are they so short of funds?

"Alright, let's not talk about that." Qin Ming waved his hand and didn't mention this matter again, he continued:

"You did a good job of on-site investigation, but now if you are a criminal policeman, even if you are a person in the technical room, you must have some understanding of other types of police, and you are now following this case to learn more things besides trace inspection.

Take the inspection report to find the map detective, ask them to call up the monitoring of the community and the surrounding streets, and check his activity trajectory according to the physical characteristics provided by the technical room. ”

When Ding Jiu heard this, he was secretly happy in his heart, although he didn't earn him 100 million, he finally achieved a small goal he set.
