"So, don't just interact outdoors."

Seeing Ken sitting on the ground with weak legs, but still hugging Cried Raven tightly, Luo An was speechless:

"Mosquito bites aside, there are so many horror movies released in the Federation every year, don't you remember the stories in them?"

Ken swallowed and said in a trembling voice:

"I ...... I thought it was all a story. ”

"The stories are inspired by life, young people."

Shaking his head, he let the two young people into the SUV to rest, and then took out his mobile phone and called the parents of the two young people, asking them to come and pick them up quickly.

"It's supposed to be the same person, Roan."

At the edge of the lake, in a deep pit washed out by the current, a woman's body was buried in the water, lying quietly inside.

Lacey stood at the edge of the pit and took a brief look, and found that the strangulation marks on the neck of the female corpse were clearly visible, there were traces of being tied on the wrists and ankles, some bruises could be faintly seen on the collarbone, and the pants of the corpse were also a little crooked.

The main thing is that the ring on the corpse's hand has disappeared.

"Okay."

Seeing Susan's body, Luo An was silent for a moment, called Augustus, and briefly described the situation here, and Augustus immediately notified the trace laboratory and asked them to hurry up and send agents here to inspect the scene.

Hanging up the phone, Luo An began to look around, and saw a row of deep footprints in the dead leaves on the ground.

"It seems that the murderer's original intention was to throw her into the lake behind the victim's back."

Lacey on the side walked to Luo An's side, looked down at the footprints, looked up at the path that was some distance away from here, and then looked at the lake that was still a short distance away, and shrugged:

"But he couldn't carry his back halfway through, so he threw the victim here."

"No, it shouldn't be."

Carefully looking at the footprints on the ground, Luo An frowned, and after bending down and squatting, he briefly measured the length of the footprints, and then said:

"The length of this footprint is definitely over 25 centimeters, and it is not clear whether it is 26 or 27.

Take the lowest number of 25 and push the formula for height according to the length of the footprint, 25 times 6.8, which is about 170, so the height of the murderer is definitely higher than 170. ”

Lacey, who came from the intelligence department, looked dazed, and before she could react, Luo An continued:

"Both Louise and the scavenger said that this white male was of medium stature.

I asked Susan about her weight before, and it was only about 45kg. ”

An adult white man with a height of more than 170 and a medium stature, under normal circumstances, it is impossible not to carry an adult white woman with a height of 1.6 meters and more than 90 pounds.

Louise and the scavengers had never said before that they saw the killer physically injured.

Clapping his hands and straightening up, Luo An turned his head to see the look on Lacey's face stunned, and then grinned: "I learned it when I was in the FBI training academy." ”

As a killer in the previous life, erasing your footprints, and how to fake your footprints to confuse trackers, is a must-learn course, such as some basics:

Young people have short steps, thin footprints, irregular distances between footprints, and crooked walking routes.

Young people have big steps, big footprints, regular distances between footprints, and walk in a straight line.

The elderly have short steps, steady walking, short footprint distances, heel pressure in the footprints is heavier than the soles of the feet, and so on.

After learning the basics, the old killer taught Luo An a lot of ways to hide his true age through steps, footprints, etc.

“OK。”

Lacey didn't ask in detail, she came from the intelligence department, and she knew a little about this knowledge, but she wasn't very proficient in it, and she didn't think about it for a while.

"So, what do you mean?"

"What I mean is very simple, the murderer's original intention was indeed to throw the body into the lake, and you are not wrong about that."

Luo An pointed to the lake not far away, and then pointed to some messy footprints beside the deep pit, frowning slightly:

"But when he got here, he must have encountered some kind of sudden incident, so he had to throw the body in a deep pit."

Hearing this, Lacey frowned: "What emergency?" ”

Luo An spread his hands: "I don't know, it's just a guess, maybe someone found the murderer's parked car." ”

"Okay."

Lacey nodded, didn't say much, and began to carefully search the perimeter of the scene with Roan.

In the ravine between the pit and the lake, on a tree growing diagonally, Luo An accidentally found a small transparent bag.

"What is this?"

Seeing that Luo An carefully picked it up from the leaves, Lacey also came over and tilted her head and asked:

"It's like a bag of flour."

"Possibly."

Luo An nodded, carefully put it away, and continued to search the perimeter of the scene.

Soon after, several agents from the Traces Division arrived at the scene in a car.

After Luo An handed over the transparent packaging bag to the other party, several two detectives from the trace laboratory department jumped into the pit and began to carefully examine the area around the corpse.

After a while, the two frightened young couples were also picked up by their respective parents.

Seeing the fierce reactions of the parents on both sides, Luo An felt that these two men and women who were looking for excitement should not be able to sleep tonight.

After the on-site inspection was completed, the body was packed up and loaded into the car, and in the previous disappearance case, because of the appearance of the female corpse in the refrigerator, he had a relationship with Luo An, and Detective Neil from the trace examination department came over.

"Hello, Nell, thank you for your hard work."

Luo An stretched out his hand, greeted Nell with a smile, and asked with a smile:

"How's it going, did you find anything?"

"It's all work."

A smile appeared on Agent Nair's round face, and when he heard Luo An's question, he briefly explained the situation at the scene, and then said:

"The victim is suspected of being assaulted by the murderer before his death, but the autopsy cannot be determined before the autopsy, and the cause of death is most likely a strangulation mark on the neck."

Luo An nodded: "OK, please notify me as soon as the autopsy report comes out." ”

"No problem."

Nair smiled and agreed to Roan, and the two sides returned to their respective cars and returned to the FBI headquarters building in New York.

——

Investigation Team 5 office area.

"Still can't find any trace of that gray sedan, Roan."

Lacey goes to inform and comfort the family of the victim Susan, while Roan unloads his gear and sits back in his chair.

Just as she was about to stretch, Mona on the side stopped typing on the keyboard and came to Luo An's side to vomit bitterness.

"There is too little networked monitoring in that area, and I can check it with one hand, and there are too many traffic arteries on the periphery, and the traffic flow is huge, so it is impossible to check for suspicious gray cars."

The gray sedan drove sideways in the house surveillance outside the forest area, because of the angle problem, the license plate of the gray sedan could not be seen in the video, and there was no difference in the windshield, so naturally it was impossible to check the other party through the traffic arteries.

The only thing that is certain is that the gray sedan has four tires and the doors are intact.

"Don't be discouraged, Mona, as long as you keep working hard, you will definitely pay off."

A bowl of hot chicken soup was poured over Mona's head, and her hair was so hot that Roan pushed her back to the computer.

"You ......"

Mona was just about to continue saying something, when Ryder suddenly pushed open the door of Investigation Team 5 and excitedly shouted to Roan:

"Roan! The portrait simulation you asked me to do, the results are out, and you will never guess who the man who appeared in the church is! ”
