Chapter 336: Motivation

After chatting a few words, Lao Wei threw himself into work again.

The main thing is to survey the little blood footprints on the ground.

Compared with the "general" guess of the suspect's height based on the marks on the cab, it is more reliable to extrapolate his figure based on the blood footprints.

However, it is also the same problem - a height of more than two meters is too rare after all, the amount of data is relatively insufficient, and the individual differentiation may be greater, or in other words, the possibility of a large error is a little greater.

The body is relatively short, but the jiojio and the stride distance are relatively large, and it is not unheard of in practice, especially for runners and fishermen who have lived on boats since childhood.

The former generally has a relatively large stride distance, and the latter generally has a relatively large ball of the foot.

However, statistically, due to the large sample size of the mainstream height range, the regression equation summarized by this law can control the error within an acceptable range.

The sample data of the "non-mainstream height range" is much smaller.

However, as Su Ping said, his height is different from ordinary people, and the markings are extremely indicative, so it doesn't hurt if the error is larger or smaller.

It's just that the smaller the error and the more accurate the conclusion, the more conducive it is for them to directly lock on to the target, so Lao Wei is still trying.

Dedicated.

After a while, he stood up and said firmly: "Look at the pattern, the suspect is wearing a pair of basketball shoes." ”

“AJ?” Qi Yuan raised his eyebrows and said.

Su Ping glanced at him: "Your basketball shoes only have AJ?" ”

"Ahem." Qi Yuan coughed dryly twice and changed the topic.

He thought of the first case he came into contact with, when he was at the scene, he tried his knife and knife, or rather, he also stared at the bloody footprints for a long time, and finally came to the conclusion that the murderer was wearing basketball shoes.

So, he said: "In these days, wearing basketball shoes doesn't mean anything, it doesn't mean that the suspect likes to play basketball." But...... Considering his height, he could really be a professional footballer. ”

"It's like farting." Su Ping rolled his eyes.

Lao Wei answered: "In the general direction, there should be these clues. I'll scrutinize the vehicle again to see if I can find subtle evidence like hair, but it will take time. ”

"Cheng, you ......"

Before Su Ping finished speaking, his mobile phone suddenly rang.

He immediately raised his hand, then took out his mobile phone, glanced at the caller ID, and saw that it was Xun Mu calling, so he directly connected and turned on the amplification: "Old Xun, what do you say?" ”

"There's an important clue from the police station below." Xun Mu's voice came out, accompanied by a series of clattering footsteps and intermittent wind sounds.

He seemed to be trotting somewhere.

Su Ping immediately came to his senses and asked, "What's the matter?" ”

"I'll cut it short." Xun Mu said: "In short, in February 01, a high school student went to the Fenghe Police Station to report the case, saying that his parents had been missing for more than a week, and the police station immediately filed a case and launched an investigation as soon as possible, but the whereabouts of his parents were never found.

Three months later, the high school student came to the police station again, saying that his parents were killed by his uncle, and the clue was taken seriously by the police station, and an investigation was immediately launched around his uncle, but in the end, due to insufficient evidence, it was impossible to determine that his uncle was suspected.

However, he has always been unrelenting, always investigating the case, and even had several physical conflicts with his uncle, and the police station mainly mediated, only once because he was more serious, and was detained for 15 days.

Since then, he has continued to investigate the case and from time to time to provide 'clues' at the police station. A few years later, his parents announced that they were dead and closed their accounts, and he was even more crazy, and until the middle of this year, he was still intermittently providing 'clues' to the police station. ”

Su Ping raised his eyebrows.

Xun Mu's narration, the logic began to gradually scatter, and it was obvious that his attention was attracted by other matters.

Listening carefully to the ambient sound, he guessed that Xun Mu should have gotten into the car, so he said, "Don't worry, you put on the headphones first." ”

"Done."

After a few seconds, Su Ping continued to ask: "Is there a problem with the clues he provided?" ”

"It's not that there's a problem, it's just that most of them don't have much value." Xun Mu's voice came out again, this time the ambient sound was much weaker, and he obviously put on headphones - the noise cancellation effect of his headphones was much better than the microphone that came with the mobile phone.

I heard him say: "Most of them are clues to catch the wind and shadows, and the brothers at the police station suspect that he has a magic barrier, although they still accept it patiently, but ...... To be honest, these clues are really useless and can't point to his uncle.

Or...... Let's put it this way, none of the clues he provided could prove that his parents were killed, let alone killed by his uncle.

And this case ...... The criminal police have changed batch after batch, and this case has been passed down in the same vein, and the brothers have reached a consensus that this case has been investigated from multiple angles and in all directions, and it should be a missing case, but he has always refused to give up and used it as a sustenance. ”

After another pause, he continued: "By the way, this young man later joined the basketball club and became a professional basketball player, based on Hua Yang's side, but he still often returns to our Yuqiao, as I just said, he is still paying attention to this case." In addition, he is two meters tall and one by one. ”

Su Ping took a deep breath and said, "You doubt ......"

"Listen to me," Xun Mu interrupted him, and continued: "We compared the victim's photos again, and found that it was very similar to his uncle, and it was basically confirmed that it should be the same person." ”

"Tsk." Su Ping pursed his lips.

Qi Yuan, who had been listening on the side, frowned slightly at this time.

Su Ping keenly caught his small movements and asked, "Xiao Qi, what do you want to say?" ”

"A digression suddenly came to mind." Qi Yuan said: "With the declaration of death of his parents, this disappearance case has actually been determined, right? ”

"Hmm." Xun Mu heard this, and the voice came from Su Ping's mobile phone.

Qi Yuan then asked: "At the same time, he suspected that his parents were 'killed', because there was no substantial support, so the police station did not file a homicide case, right?" ”

"Yes."

"And if a homicide case is not investigated, the prosecution period is up to 20 years." Qi Yuan continued: "His parents disappeared in February 01, and now it is December 20......"

Hearing this, Su Ping was thoughtful.

After a while, Su Ping asked, "What do you mean...... Could it be that he consulted the relevant people and found out that the case about his parents was about to pass the prosecution period, so he couldn't sit still and was determined to take revenge himself? ”

"That's what I thought." Qi Yuan said: "If the murderer is really him, and the victim is really his uncle, this may be his motive for committing the crime." ”
