Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

Chapter 676 Lu Chuan’s identification and analysis results

Although there are very few clues in the case, the crime team has sorted out the clues after three days of investigation.

First of all, Wang Song's investigation has eliminated the suspicion of an expedition team that entered the mountains at the same time as the missing and murdered team.

Of course, these are just the current findings.

If new clues are discovered later, suspicion may be directed at these teams again.

In addition, Song Mingguang's investigation has basically figured out the basic personal circumstances of the five victims.

Strictly speaking, it is the personal circumstances of the three victims and two missing persons.

The four college students have relatively simple family backgrounds and school backgrounds.

There is basically no possibility of killing due to personal background reasons.

Moreover, even if this is possible, the possibility of the other party choosing to kill people in Beiliang Mountain is not high.

At this time, what was needed most was Lu Chuan's discovery.

People outside have no idea what's going on inside.

Evidence is always the most important basis for solving a case.

The environment inside Beiliang Mountain is complex and the terrain is dangerous.

Although the general scope has been locked, case investigation is not that simple.

Combined with various situations discovered so far.

There are many people who depend on the mountains and eat the mountains.

"Let's talk about the time of death first."

In the past three days, Lu Chuan was so busy that he only slept for four or five hours.

There are many natural villages around Beiliang Mountain.

"First of all, let's report on the identification of the skeleton."

Li Donglin turned his attention to Lu Chuan.

"The time of death of the victim, based on the degree of skeletonization, should be about half a year."

I did get a lot of clues.

"Analysis of the distance from where the bones were found to the time outside into the mountain shows that the expedition team should have arrived near the crime scene on July 7."

Lu Chuan has re-identified and analyzed the three skeletons that have been discovered in the past three days.

Lu Chuan conducted a very detailed analysis of these items one by one.

Missing and murdered persons leave numerous items at crime scenes.

It is impossible to further identify the criminal suspect only through the inferences of the investigators of the serious crime team.

The possibility of locals committing the crime is very high.

"Based on the reported information, the original plan of this expedition team was to enter the mountain on July 7 and leave on July 2."

"The timing of the two coincides."

The main purpose of Lu Chuan's analysis of this point was to confirm the direct evidence of the victim's time.

The expedition team entered the mountain on July 7 and planned to leave the mountain on July 2.

This time is only the time to report to Beiliangshan Police Station.

It is also the theoretical time frame within which the team’s victims disappeared.

But in fact, when the victim was killed cannot be confirmed through reasoning, but only through evidence.

The degree of skeletalization of the corpse is direct evidence.

The environment in Beiliang Mountain is relatively hot and humid, and even though it is winter, there is no snow inside.

It is a very suitable environment for corpses to be skeletal after death.

"The other is the determination of the cause of death."

"The three male corpses that have been discovered basically all have fracture injuries."

"It can be judged that the deceased must have gone through a violent struggle before being killed."

"One of the skeletons," Lu Chuan turned on the projector and numbered the three skeletons, "is the skeleton we saw three days ago. The arm was exposed, the hyoid bone was broken, and the ribs were broken."

"It can be judged as suffocation."

"Skeleton No. 2 has a broken leg bone." The photo on the projector showed the cracks in the broken bones.

"This fracture surface has traces of fine comminuted fractures, which is consistent with the characteristics of the tibia being broken due to blunt force beating."

"From the traces of leg bone fractures, the size and shape can basically be judged to be fractures caused by a blow from a cylindrical object such as a trekking pole or a steel bar."

"In addition, look at the lower end of the spine of Skeleton No. 2. There are scratches from a sharp weapon."

"It should be that the murderer stabbed the victim's lower back with a knife from behind, causing scratches."

"And here..."

Displayed on the projector is the skull of Skeleton No. 2.

"There are transverse cracks on the occipital bone and longitudinal cross cracks."

"The deceased suffered severe impacts to his head from the front and back of his head."

"And the mark of this scar, compared with the fracture mark caused by the leg bone just now, the blunt force impact area that caused this scar is larger."

"In other words, the object that caused the leg fracture and skull blow to corpse No. 2 were not the same."

"The object that caused the skull fracture was more like a hammer or something like that."

"The fatal injury of deceased No. 2 should be on the head."

Lu Chuan's introduction was very detailed and meticulous, and he carefully analyzed and identified every scar and fracture of the deceased.

And the results obtained can be understood by everyone present.

There were probably three people who attacked Skeleton No. 2.

One used something similar to a trekking pole, causing victim No. 2’s leg bone to fracture.

Another person held a sharp weapon and caused injuries to the deceased's lower back.

Another one is to use a hammer or something like that to hit the deceased on the brain.

And this blow was the fatal injury.

"So, based on preliminary findings, the murderer who caused the injuries on Skeleton No. 2 is likely to be three people."

"We are looking at the condition of Skeleton No. 3."

"Compared to Skeleton No. 1 and Skeleton No. 2, Skeleton No. 3 has more scars on its body."

On the projector, all the traces of injuries on Skeleton No. 3 appeared.

"Skeleton No. 3's legs and arms were fractured. After comparison of the fracture marks, it was determined that it was the weapon that caused the leg bones of deceased No. 2 to be fractured."

"This also verifies the judgment we just made. The murderer is definitely not the same person."

"There is also a fracture injury to the ribs on the chest of Skeleton No. 3. The fracture area is large and oval-shaped."

"Comparing the fracture marks on Skeleton No. 2, we can determine that it was caused by the murder weapon that caused the occipital fracture of Skeleton No. 2, that is, a hammer or something like a hammer."

"And here."

Lu Chuan pointed to an enlarged photo of the leg bone.

"The upper part of the left leg bone, which is the thigh part."

"Look at these tiny white splotchy marks."

Even if the photo is enlarged, these white spots are not particularly clear.

"What's happening here?"

"The tip of the knife!"

Lu Chuan picked up a fruit knife on the table and pointed to the tip of the knife to explain to everyone.

"Before victim No. 3 died, someone stabbed his thigh with a sharp instrument, and the tip of the knife was pressed against the bone."

"And more than once."

"And here."

Everyone observed carefully and saw a thin white trace, continuous, about ten centimeters long.

"A white mark about 10 centimeters long is the scratch left by the tip of the knife on the bone."

"That is to say, the murderer used a sharp knife to pierce Victim No. 3's thigh multiple times, and then cut another ten centimeters along the muscle!"
