Chapter 856: Hancheng Strategy (Ten)
"What is this?" Aubrey, whose face still couldn't help but turn pale, asked when he saw Jack using tweezers to pick out a thin black thread from the corner of the deceased's eye and put it under a desktop magnifying glass for closer inspection.
The third victim's death time was no more than 4 hours. Although the wounds on his face were equally horrific, the psychological impact on people was much better than that of the previous one.
Clay's performance this time was very different from before. Even a weakling like Aubrey didn't show much discomfort and was very attentive to observing and learning.
"It's an absorbable suture, model 7/0." The female forensic doctor sent by South Korea to assist looked at it in front of the magnifying glass and said with certainty.
"Is it the kind of cosmetic thread commonly used in cosmetic surgeries?" Jack took the glass dish from Clay and put the suture in it.
The female forensic doctor nodded. Although her expression could not be seen due to the mask, her confusion could be seen in her eyes, "Yes, it seems like she has undergone an extreme plastic surgery.
The two previous corpses were severely decomposed, which may have led to some misjudgments on my part. "
"What do you mean?" Although the female forensic doctor's accent was a bit strange, everyone could finally communicate directly, so Clay quickly asked.
"For example, her jaw." Jack suddenly realized after being reminded by the female forensic doctor, "The wound on the mandible of this corpse was not caused by brute force using tools such as pliers. The incision on the bone was more like imitating a T-shaped osteotomy." "
"Please speak human language." Aubrey said that he had not heard of some professional words.
“T-shaped osteotomy is a surgical method for chin plastic surgery. By cutting off a section of bone in the middle of the chin, and then inserting titanium nails to push the mandible bone toward the middle, it can make the chin more pointed, forming a so-called V-shaped face. "
Jack gestured with his fingers as he spoke. This surgery is much more complicated than a simple chin circumcision, but it can effectively shorten the length of the chin and make a person's entire face look more childish.
Then he pointed to the deceased's nose and asked, "Is this a sign of imitating rhinoplasty surgery? Both sides of the nostrils were cut, and the cartilage of the nasal septum also showed signs of being cut."
The female forensic doctor stood opposite him and hummed after hearing this. She was examining the canthus of the deceased's eye. Jack had just discovered the suture line at this location. "In addition, the canthus of the eye was cut open and then sutured. This is the canthus opening." Surgery, in addition to having part of the eyelid removed.
However, I am not sure whether it was a simple eyelid plastic surgery or a double eyelid surgery. The deceased had double eyelids, just like her nose, and did not need rhinoplasty. "
"But there were no surgical sutures found on the faces of the first two victims, right? Did they degrade as the corpses decomposed?" Clay roughly understood what extreme plastic surgery was, and the murderer thought the victim was a Experimental subjects practicing plastic surgery.
Jack shook his head, "Even the absorbable sutures are artificially synthesized with protein. Absorbable means that the human body will absorb this protein, but it is not so easy to degrade on the corpse. This is a new method, indicating that the murderer The methods are improving.”

After bidding farewell to the professional female forensic doctor and leaving the morgue, the three of them met Ma Xidao waiting at the door. He was grabbing a fried dough stick and eating it with gusto. He also had a bag in his hand, which seemed to be breakfast for everyone.
"Eat it while it's hot. It's hard to find it in Korean breakfast restaurants. Coffee shops don't open until 9 or 10 o'clock."
Although his behavior was somewhat rude, he gained the unanimous gratitude of the three FBIs. They were woken up in the middle of the night and were already ravenous by now.
The previous autopsy was only a preliminary examination and had not yet progressed to the disembowelment stage. Even Aubrey didn't take much time to recover and grabbed the fried dough sticks and ate them while walking.
Koreans, especially young people, basically do not have the habit of eating breakfast. Coupled with their bad eating habits of eating kimchi, their incidence of gastrointestinal diseases and gastric cancer has always remained the highest in the world.
The four of them had breakfast on the roadside. Perhaps because the hot pot meal last night brought the two parties closer together, Ma Xidao did not wear formal clothes today, but put on a blue and white striped sweatshirt, which matched his figure. , looking more like a fitness instructor than a police officer.
He casually wiped his oily hands with paper, took out an ordinary tourist map from his pocket and spread it out in front of everyone.
Itaewon is a section composed of a main street and many alleys, which is about a 1.4-kilometer long section from Itaewon 1-dong to Hannam 2-dong.
The original meaning of "dong" in Korean is village, and later it gradually evolved into the meaning of neighborhood, which is somewhat similar to the term "new village" or "street" in Chinese cities.
Ma Xidao drew a cross in an alley on the west side of Itaewon's main street, "This is the result of my team's investigation just now. The place where the first deceased, Barbara Walker, should have been dumped is here."
Jack took the map and clicked on the cross in the northeast of Itaewon, "Is this the location of the abandoned body of Jessica, the second deceased?"
"That's right, there are only two alleys between the two sides." Then Ma Xidao drew a cross on the southeast corner, forming a triangle with the previous two crosses. "This is the place where the third victim's body was abandoned yesterday. The two locations are two and three streets apart.”
Clay grinned, feeling a little unbelievable, "Does this mean that the total of the three corpse dumping locations does not exceed 4 streets?"
This murderer is very brave. Jack's expression is also very interesting. He thought that if Red was here, he would be happy because it would be a simple geographical profile he had done. If he used three dots to draw a circle, the total area would be less than 1 square kilometer.
"The murderer may be someone who works or lives in this area."
But as a local, Ma Xidao wants to know more about the situation in Itaewon. Looking at the three crosses on the map, he put his hands on his waist in embarrassment.
"This investigation is not easy to do. This is the most central and prosperous area in Itaewon. Did you get anything in it before?" He said, nodding towards the morgue.
Jack recounted their latest findings, "Given that South Korea is the world's plastic surgery capital, plastic surgery can even be considered a part of your culture.
At the same time, considering the experience required to perform these operations, we suspect that the murderer may be Korean, and his profession is related to plastic surgery."
Ma Xidao scratched the back of his head in distress, "Almost one-third of the beautiful girls in Seoul are around here, and there are black clinics that can perform plastic surgery all around. But finally we have a direction, can we narrow down the target a little bit, that is, use your geographic profiling?"
"OK, I'll try." Jack smiled and took out his mobile phone to call Hannah.
——
"Yes, Alice and I checked the victim's credit card spending records. Barbara Walker went to the Red Petals flower shop to buy flowers almost twice a week, and Jessica went to the Shining Nails salon once a week for a manicure. The two places are less than 20 meters apart."
Hannah yawned after she finished speaking, but there was still excitement in her voice that could not be concealed. "The store where Elsa Byquist worked is also on the same street. If she went home directly after get off work, she would pass the same place every day."
According to the address she gave, Jack drew a circle at a location between the three forks on the map.
