Chapter 680 Clue Analysis

Director Qin was making notes on the whiteboard with a pen as he spoke.

"After we entered the scene, we first found a large number of messy footprints next to the overturned tractor."

"Preliminary assessment shows that these are the footprints of four men, who are between 170 and 180 cm tall and weigh about 65 to 70 kg."

"Then, four bullet casings were extracted at this location."

"Judging from the shell casing, it is a smuggled standard-issue pistol with a caliber of 9mm."

"We need to go back and do ballistic analysis to determine the specific model."

Everyone else present was looking at the whiteboard very seriously and listening to Director Qin's explanation.

While Director Qin was pausing, Qi Tongwei asked:

"A 9mm standard pistol? This kind of gun shouldn't be easy to deal with, right?"

Director Qin nodded and said, "Indeed, most gun-related cases involve privately modified hunting rifles."

"Even if there are pistols, they are smuggled goods from small workshops. This kind of large-caliber military pistol is rare."

Hearing the conversation between the two, Ren Yuanhua frowned and seemed to be thinking about something.

"Old Qi, don't interrupt Director Qin's train of thought." Qi Tongwei wanted to say something, but Sun Liancheng stopped him.

"Director Qin, please continue."

Director Qin returned to the case and continued:

"Here we found the first pool of blood."

"Also, next to the bloodstains, there were signs of dragging."

"Then we found a lot of broken glass and marks left by the wheels when the car was reversed."

"Then ten metres back is where the rear end of the vehicle hit the rock and stopped."

"On the rocks nearby, we found bullet holes and footprints."

"Then, bullet holes and footprints were found on a stone on the side of the road, as well as blood dripping."

Director Qin was making marks on the whiteboard as he spoke, trying to make it as clear as possible for others to see.

"After expanding the scope of the survey, we found cigarette butts and traces of trampling on the hillside above the mountain road."

"Preliminary judgment shows that there are at least two people."

“In addition, blood stains were found on the hillside.”

"Finally, we found footprints at the bottom of the mountain road, and there were traces of someone sliding down from above."

"Judging from the footprints, there should be three people entering the forest."

"One of the footprints was only size 38 and was relatively shallow, so it must have been left by a girl."

"Tan Xiaofang." Qi Tongwei couldn't help but blurt out what Director Qin said.

"The person who left this footprint must be Tan Xiaofang."

Qi Tongwei seemed a little excited at this time.

If Tan Xiaofang is still alive, it means that Da Liu and Zhang Han should also be alive.

And Director Qin said there were three people's footprints, so it is likely that they were from the three of them.

That's why Qi Tongwei couldn't suppress his excitement.

Realizing that he had interrupted Director Qin again, Qi Tongwei said apologetically:

"Excuse me, Director Qin. Please continue."

Director Qin exhaled and said, "Based on the situation at the scene, this is roughly the information we have."

"Footprints, bloodstains, cigarette butts and bullet shells collected at the scene need further testing."

Then he looked at Sun Liancheng.

"Team Leader Sun, I have said everything I want to say."

Director Qin is from the technical department, and his main job is to survey the site.

His words just now described what he saw at the scene one by one.

But no inference or judgment was made.

Because it is the job of detectives to make reasonable inferences and judgments based on the situation at the scene.

This is not the strong point of their technical staff.

"Thank you for your hard work, Director Qin. Please take a seat." Sun Liancheng nodded.

Then he looked at Qi Tongwei.

"Old Qi, I see you have a lot to say. Director Qin has finished speaking, now tell me what you think."

Qi Tongwei could no longer hold back and immediately stood up and walked to the whiteboard that Director Qin had just drawn.

Said: "Based on Director Qin's investigation of the scene, the situation at the time should be like this."

"There are four suspects here, blocking the mountain road with an overturned tractor."

"At the same time, there were two people on the side of the hillside of the mountain road. They were responsible for pushing the rocks down to block the retreat."

"After Liu and Zhang Han's car turned the corner, they must have seen the overturned tractor and stopped the car."

"Then the four suspects opened fire first. Liu Da and Zhang Han reacted quickly and backed up, firing back at the same time."

"So one of the other party was hit at this location, and the other party's bullet shattered the car window."

"When we were backing up here, the car was blocked by rocks that rolled down, and at the same time, two people on the mountain rushed down."

"That would explain why there were bullet holes on the roof and hood."

"Da Liu and Zhang Han should choose to get out of the car and fight back at this time."

"In the end, the three of them had no choice but to slide down the mountain road to retreat into the forest."

"The other side saw them entering the forest, and it was almost dawn, so they withdrew with their accomplices."

"The car must have caught fire during the gunfight when a bullet hit the fuel tank or something."

After saying this, Qi Tongwei put down the marker in his hand.

"I'm done. This is probably the general situation."

Sun Liancheng did not express his opinion directly, but looked at Ren Yuanhua.

Asked: "Old Ren, tell me what you think."

At this time, Ren Yuanhua already knew the details of the case.

As an experienced criminal policeman who has worked on the front line for decades, he naturally has rich experience.

He said, "I think Lao Qi's analysis makes sense and roughly reconstructs what happened at that time."

"From the situation at the scene, first of all, the other party was well prepared."

"Not only did we know the exact time when Liu and his team would pick us up, but we also knew how many people were there."

"I'm not flattering you, but the two people who went there are the best and brightest members of your investigation team."

"If it were someone else in this situation, it would be really dangerous."

Qi Tongwei fully agrees with this point.

It is indeed not easy to escape unscathed when six armed men are attacking from the front and back.

At this time, Zhao Jie on the side said: "Team Leader Sun, Director Qi, can I add something?"

Sun Liancheng gestured, "Captain Zhao, feel free to speak up if you have any ideas."

Zhao Jie stood up and said:

"From Xiapo Village to Wanlin County, there is a 30-kilometer mountain road."

“Although it’s not as easy as a road, it can accommodate two cars running side by side.”

"Only the section where the accident happened has two consecutive turns, so it is relatively narrow and can only accommodate one car."

"The fact that the suspects chose to come here shows that they are familiar with this section of the mountain road."

“We can’t say they were locals, but at least we can be sure that they didn’t randomly choose the crime location.”
