After a careful search of the area around the crater, nothing was found except for the bloodstained stone.

After Yu Yu in the pit put the maggots and meat pieces in the bag, he called Xiao Ran and Zhang Lei over, pointed to a trace on the pit wall, and said: "These scratch marks I just found must have been left by the deceased when he grabbed the pit wall with his hands and struggled." This also confirms your claims!"

Half an hour later, the three of them were basically sure that there was nothing to see at the scene, and they returned to the team.

At this time, more than ten hours have passed since the body was found, and the identity of the deceased has not been confirmed, Zhang Lei and Yu Yu returned to the technology center with the stone, and they still have a lot of work to do.

In addition, due to the gradual and detailed clues in hand, it can be basically determined that this matter is likely to be an intentional homicide case of a heinous nature, so the bureau decided to file a case for investigation, and the '5.22' task force was formally established.

Once the nature of the case is determined, the intensity of the investigation will naturally be raised to a higher level.

At noon, Liu Qing and the three of them, who went to the cross-country event organizing committee to investigate, returned to the team with what they learned.

"Team Xiao, this is the list of all the participants during the game on the 12th, as well as relevant information. ”

Liu Qing handed Xiao Ran a thick stack of information sheets and took out a mobile hard drive, "This is what we copied, the recorded video of all the participants arriving at the finish line at the end of the race on the 14th." ”

"As far as we know, there were a total of 344 people who participated in the cross-country race, and four of them withdrew due to physical reasons, and these people did not match the age and physical appearance of the deceased. ”

He Liang, who went with him, added: "The organizers also told us that there were no accidents during the competition. In addition, on the way back, I went through the information of these participants and found that there were a total of 25 people who matched the age group of the deceased, but these people had completed the journey.

The end of the game was on the 14th, and the 14th was 8 days before we found the deceased, but Forensic Doctor Yu said that the time of death of the deceased was about 10 days, or even more than 10 days, and if the deceased was a participant, the time did not match at all. ”

"You're right, just on the face of the data, it's clear that the deceased wasn't a participant. Xiao Ran flipped through the information book and read the names of the contestants marked by He Liang with a pen.

He looked up and smiled and said, "But sometimes, suspects just like to create this illusion and disrupt the direction of our case." So, don't be fooled by the superficial data!"

Xiao Ran handed the information book to He Liang, "You contact these 25 people, and also contact the 4 people who withdrew halfway, and also contact the emergency contacts left by these people, determine the current situation of these 29 people one by one, and pay attention to the people who can't be contacted." ”

"Yes. ”

He Liang responded excitedly, and repeatedly warned himself in his heart that this was the first time he had received a task, or in such a major criminal case, and there must not be a single mistake!

Holding the mobile hard drive, he returned to his desk to watch the video at the end of the event, and before he sat down, Yu Yu called again.

Xiao Ran answered: "Is there any progress?"

"Yes, good news, bad news. ”

Yu Yu said: "The good news is that after our analysis and comparison, the stone is the tool that struck the deceased's phalanges, and the scattered blood stains on the stone belong to the deceased.

And in addition to the DNA of the deceased, we also extracted unfamiliar DNA from the stone. It was the bloody palm print, and it is almost certain that the bloody palm print was left by the suspect, and the suspect still suffered some injuries on his hand when he committed the murder. ”

"What about the bad news?" Xiao Ran then asked.

"The bad news is that although their DNA was made, we don't have the data to match it in our database, and it is not possible to use DNA to directly identify the deceased and the suspect. ”

Yu Yu said a little frustratedly: "There is another one, the ice axe of the off-road rod has not extracted the DNA of the deceased, and it can basically be considered that this off-road rod is not a crime tool that caused a special fracture of the deceased's skull." ”

"Yes, at least make the suspect's DNA, let's see what we do. ”

Xiao Ran hung up the phone, told He Xiaoli the latest situation, turned on the computer, and watched intently the end video of the cross-country race that Liu Qing and they copied.

This video has a clear picture, and it seems that it is not only used for recording, but also for rechecking the results of the participants.

It took a long time to end the recording, starting at 6 a.m. on the 14th and continuing until 4 p.m.

During these ten hours, the participants arrived one after another, with the first place arriving at 6:50 a.m. and the last crossing the finish line at 4 p.m.

And the atmosphere of the scene is also a little utilitarian, when the first place crossed the finish line, the onlookers and support groups on the scene cheered and cheered, and it was very lively.

As for the bad results and the late arrival, the only people I saw at the finish line were two or three staff members of the race team.

There was no cheering, no applause, no one to confirm their identity, just a casual signature on the notebook and a hasty departure.

Xiao Ran watched the video at the end of the race as fast as possible, counting the participants who crossed the finish line one by one, except for the 4 who retired halfway, the remaining 340 people were a lot, and they all reached the finish line.

Moreover, none of these 340 people, as well as the people who appeared around, touched Xiao Ran's Eye of Justice, which basically means that there is nothing wrong with these 340 participants.

Could it be that the deceased was one of the four people who quit halfway through?

Xiao Ran denied this idea, and Liu Qing said that the four people who withdrew from the race halfway were due to physical reasons, and they were sent to the hospital all the way by the event party, and there was no objection.

As a result, there were quite a few people participating in the race on the 14th. But when the deceased was on the 14th, it was likely that they had already given birth to maggots.

This is very strange, could it be that the deceased is really not a participant in the cross-country race?

After watching the video of the end of the game, Xiao Ran tapped his fingertips on the desk and thought for a while.

"Team Xiao, Team Xiao, I'm done. ”

At this moment, He Liang walked over quickly with the information book, sat down and said, "I contacted these 29 people, as well as the emergency contacts of these 29 people. 27 of them confirmed that they were all right, and I also added a friend to open the video, and compared it with the photos in the data book, and confirmed that it was correct. ”

Xiao Ran took a bag of milk from the drawer and handed it to He Liang, and the little brother's voice was a little hoarse when he called.

He Liang opened the milk and drank it in one go, and then said: "However, two of these 29 people I haven't contacted. ”

He Liang opened the information book of the contestants, pointed to a 47 or 8-year-old man and said: "The first one is this, named Yan Sanshu, 49 years old, from this city, and his mobile phone is not in the service area. I contacted his emergency contact, who was his wife.

Yan Sanshu's wife said that Yan Sanshu has been out of competition for the past month and has not been home for more than a month, and she said that it is common for her husband not to go home for one or two months, and Yan Sanshu now seems to be playing cross-country somewhere in Qin Province. ”

After talking about Yan Sanshu's situation, He Liang turned a few more pages, pointed to a data column named Liu Mingcheng and said: "The second person who can't be contacted is called Liu Mingcheng, 51 years old, from Yancheng, and his mobile phone is also not in the service area......"

Looking at the one-inch photo of Liu Mingcheng on the information column, Xiao Ran's eyes tightened, and he suddenly interrupted He Liang's words: "Are you sure this Liu Mingcheng is a participant?"

He Liang was stunned for a few seconds, and said blankly: "It should be right for the event party, right?"

That's right, Xiao Ran doesn't know.

But Xiao Ran can be sure that in the video of the 340 runners walking through the finish line that he just watched, he didn't see this face crossing the finish line!
