Based on the traces of the crime scene and the autopsy, Irina drew a sketch of the suspect. In fact, in terms of appearance, it can no longer be called a "human", at most it is just a half-human, half-beast humanoid creature. The overall shape of the monster is like a slender, oversized maggot that stands up for most of its body, of which the upright part accounts for two-thirds of the total length, and is marked about 2 meters 2 long according to the proportion, which is far beyond the height of a normal person, so that this monster has a condescending attack advantage. Its body color is gray, which is conducive to its stealth at night, although it is more than three meters long, it should weigh no more than 100-120 kilograms, and its slender body can easily pass through various pipes in the lower town; In addition, its upper limbs are well-developed and stout, with three fingers, two in front and one in the back, the fingers have only one joint, and the anterior segment is a sharp claw, which is a very effective tool for tearing; It also has a long face filled with sharp teeth that are equally good at tearing but not easy to chew, and its jaw bones may be able to dislocate themselves like snakes in order to swallow larger prey.

To heal eyesight, it may not be or very weak, perhaps relying on sound waves or heat energy to find prey.

After finishing the final stroke, Irina took two steps back and admired her masterpiece, "Such a big monster shouldn't suddenly appear, even if it grows quickly, there should be a growth process, and this form is ......"

Irina was pondering, the phone rang interrupted her thinking, Irina picked up the phone, and the voice of Ke Junxia, who had been missing for two or three days, came from the receiver.

"Hello, Your Excellency Medical Examiner Irina." Ke Junxia said in the tone of a top hat as usual: "I got some new news, I don't know if it's convenient to visit now, or do I need to make an appointment?" ”

As soon as Irina heard that it was Ke Junxia, she immediately scolded unceremoniously: "Make an appointment for your size, you'd better appear in front of me within two minutes, I'm in the office of the Special Investigation Bureau." ”

Ke Junxia said: "In less than two minutes, I will be at the door of your office." ”

There was a knock on the door, and the rhythm was moderate, neither fast nor slow.

Irina sat back in her office chair and shouted angrily, "Come in, the door is unlocked." ”

Ke Junxia opened the door and walked in, Irina deliberately didn't look at him, pretending to look at the documents in front of him, until Ke Junxia handed Armin's transcript to Irina and said, "This is Amin's transcript, and now the transcripts of all relevant witnesses in the case file are complete." ”

Irina found the strange fingerprint on the record, she was a senior forensic doctor, and with a faint smell and strange color, she concluded that the fingerprint was a blood fingerprint, although the extraction of blood fingerprints was a bit rude, but as a DNA deposit, the probative power of this forensic method is very high. However, Irina still looked a little dissatisfied, and said, "It's just a witness, as for it." ”

Ke Junxia smiled: "He volunteered to help me, who made him owe me?" ”

Irina didn't want to dwell too much on this issue, so she took out the first draft of the forensic report and the analysis of the county identification that she had compiled in the past few days, handed it to Ke Junxia, and said: "Theoretically, my work on this case has been completed, so don't bother me if you have nothing to do in the future, but you can still ask if you don't understand anything now." Sit back and watch. ”

Ke Junxia nodded gratefully, sat down in the guest chair, and began to look through the report, which made him admire Irina, the whole report was detailed, layered, and concise and easy to understand, and the photos and charts were accompanied by detailed explanations. However, when he entered the door, Ke Junxia saw the fake image of the suspect that Irina had just completed and had not yet been included in the report, so when he saw the part of DNA analysis, he couldn't help but look up and ask: "Human DNA?" Mutants? His gaze fell on the imaginary picture of the suspect on the side of the office, and according to the analysis of the picture, what point does this guy look like a human?

When it came to the professional part, Irina became professional and patient, and she did not get impatient because of Ke Junxia's childish question, but explained: "This is based on samples of saliva and other traces left at the scene, including DNA extracted from the extremely tiny residue of the bullet at the scene, although it looks like a beast, it is indeed human. ”

Ke Junxia put down the report, walked to the portrait and looked at it carefully, shook his head and said, "It's really incredible." ”

Irina said: "This is just my hypothetical picture, the real suspect may be different from this, but the main physiological characteristics are not too far apart, this is a dangerous beast." ”

Ke Junxia muttered: "I always thought that my mother didn't hit the target when she was defending herself, but just now you said that the residual material was also found on the bullet, but there was no blood or bodily fluids of other creatures left at the scene, I really can't figure it out." ”

Irina said, "When you solve this case, you will be able to solve all the answers." But it may remind you that this monster may be immune to physical damage such as gunshots. This kind of case has also happened in the history of anthropology, such as the ghost incident more than 170 years ago......"

Irina doesn't like guns and the like, so she will preach her theory of the uselessness of firearms whenever she gets the chance.

Of course, Ke Junxia disagrees with Irina's theory, and anyone who grew up in Xiacheng will not agree, but Ke Junxia did not refute, but diverted the topic and put forward his own opinion: "It is absolutely impossible for such a big monster to appear out of thin air, Your Excellency Irina, I asked you to go to the General Bureau last time to ......"

"Sure enough, it's up to now." Irina was secretly happy in her heart, and she opened the cabinet door under the desk quite proudly, took out the case file materials that were more than a foot high, and slammed them on the table, "Can't I think of what you want?" Of course I went to check, but the file management of the Xiacheng District Bureau is too chaotic, and many of the things that should be reported have not been reported, and only these nine cases can be found at present, but there are too many, I roughly flipped through them, and I haven't had time to make a record of the inner volume. ”

"Thank you so much!" Ke Junxia's eyes lit up, and he picked up the top case file as if he had found a treasure, and quickly flipped through it.

Irina sighed, although Ke Junxia saw it quickly, but the dossier that was more than a foot high, even if he didn't stop looking at it for a second, he had to see that it was going to be in the middle of the night. So Irina grabbed a whiteboard, took a pen from the drawer, and then knocked on the whiteboard and shouted to Ke Junxia: "Hey, hey, look here, I've said that I've browsed it before, so let me help you improve your efficiency." ”

Ke Junxia saw that Irina was willing to help, so he put down the case file and put it on his lap, while his hand did not leave.

Irina saw that Ke Junxia was willing to be taught with an open mind, and her heart was secretly happy, so she picked up a pen and wrote a "1" on the whiteboard, and then said: "The reason why I chose these nine cases is because the way these nine cases were committed and the victim's wounds are closest to your mother's case, so we assume that these wounds are all committed by this one suspect." Since we want to find the source, we still need to list and analyze these cases according to the time of occurrence and the relevant circumstances of the victims. ”

Ke Junxia nodded, Irina walked back to her desk slowly, picked up the water glass on the table and took a sip, then walked back to the whiteboard, wrote on the whiteboard, and said while writing: "Your mother was killed after midnight, and when she came home from work and entered the door, the suspect attacked from behind her and ripped her throat, which was a fatal injury, but your mother fought back with serious injuries." The suspect then tore and devoured the soft, fatty parts of your mother's body, as well as her internal organs. Another set of data is very important, your mother is 165mm tall and weighs 65kg, which is a slightly chubby body type. ”

After Irina finished saying this, she deliberately looked at Ke Junxia's reaction, and saw that Ke Junxia was very calm, and he was not rationally unstable because of the mention of his mother's tragic situation, so she continued to write a "2" on the whiteboard and then continued: "Three months ago, a night girl was attacked and killed, with a height of 157mm and a weight of 59 kg. ”

"Seven months ago, a drunk girl was attacked when she came home alone at night, 152mm tall and weighed 55kg."

"Another 11 months ago, a female high school student who was studying on her own at night was attacked, with a height of 155m and a weight of 53 kg."

"Fifteen months ago, a runaway girl was attacked, 148mm tall and weighing 49kg."

……

"The last case of the attack was four years ago, a 9-year-old boy, who was thought to be missing at first, but then his body was found in the drain, and the death was the same as in the above case. Nine cases, counting your mother, ten cases, ten victims. ”

Irina finished her long story, put down the pen, walked back to the desk, grabbed the water glass, drank it all, put it down, and looked at Ke Junxia.

Ke Junxia frowned, walked over and picked up Irina's water cup, went to the water dispenser and filled it with water, then put it back in front of her, sat down on the guest chair again, held his chin in his hand and said, "The pattern is obvious, this monster attacks and eats every three to five months, and grows a lot more when it carries out the next attack. From the point of view of the object of the attack,At the beginning, there was no limit to men and women,Later, it developed to only attack women who were slightly fat.,There are two possibilities.,Women and children have limited defense capabilities.,But from the point of view of the feeding part,This monster is more willing to devour and tear the part with a high fat content.,And it's easy to digest.,Anyway,This monster's capacity utilization rate is very high.,You can grow quickly by eating once.,And the proportion of intake growth may exceed 1:1.。 ”

Irina said: "Across the biological world, there is no wonder, there is a mammal called ** on the earth, in the cub period, sucking more than 100 kilograms of breast milk every day, but can grow 200 kilograms, the production capacity ratio is higher than this monster." ”

Ke Junxia was not interested in Irina's words, he didn't come to study, "Is there a map of the dungeon?" I want to mark the location of each crime. ”

Irina turned on the projection and mapped out a three-dimensional topographic map of the dungeon in the room, Ke Junxia found an electric pen from Irina's desk and began to mark it on the topographic map, when the last case occurred was marked, that is, the case of the nine-year-old boy, Ke Junxia's brows furrowed even tighter, and he said categorically: "This is by no means the last case, the monster also needs to eat before attacking this boy." ”

Irina said: "But there is no record of the wreckage before, and there is no report." ”

Ke Junxia said: "Your Excellency, you only investigated the murder case, have you forgotten the last case, where did the boy's body come from?" ”

Irina gasped, in fact, with her intelligence, she would not be unable to understand such a simple question, but she was guilty of pedantic, and she thought about the problem too much. Of course, the monster also needs to eat before attacking a nine-year-old boy, and it was smaller then, so it only attacked smaller targets, toddlers and babies, and these children were petite enough to be taken down the sewer by the monster after being attacked, and they were eaten there! Therefore, after the nine-year-old boy, the backlog of cases that should be investigated should not be a homicide case, but a case of the disappearance of infants and young children!
