After nightfall, Xiao Chen was weighing the organs of the deceased in the autopsy room, when a sound came from outside.

"Old Xiao, Old Xiao! Is the autopsy report out? Is this one on the table? I'll take it first! I've got you a supper, I'll put it here first......"

The assistants laughed for a while, and every time Captain Song came to see Forensic Doctor Xiao, the movement was as loud as beating gongs and drums.

Xiao Chen sighed, "I'm annoyed, this guy will come in a while!" ”

He instructed his assistant to take over the rest, took off his gloves and washed his hands, changed out of his sterile protective suit, and went to the laboratory outside.

Sure enough, five minutes later, Seinfeld came back while reading the report and asked, "The time of death is eight o'clock in the evening!?" ”

Xiao Chen calmly explained: "The liver temperature shows that the time of death is eight o'clock, but the body surface symptoms are all shown as nine o'clock, and the only explanation is that someone changed the temperature at the scene, continuing the process of changing the corpse." ”

Song Feipeng frowned, sat down, took a cigarette in his mouth, and Xiao Chen said, "Don't smoke in the laboratory!" ”

"But the liver temperature may not be accurate, if the deceased had fever symptoms before death...... Song Feipeng muttered.

"I'm checking her kidneys and liver." Xiao Chen replied briefly, "I will add new discoveries in the future." ”

Song Feipeng carefully reviewed the autopsy report again, and the two hammer wounds on the back of the deceased's head were the earliest and most fatal, causing a fracture of the occipital bone and an intracranial hemorrhage caused by meningeal artery injury, and two places on the spine should have been struck while the deceased was still struggling.

Xiao Chen continued: "Regarding the form of the murder weapon, I still need to do an experiment, and the results will be available tomorrow!" ”

"Okay...... You can test these two things too! Song Lang pointed to the magazines and phosphors on the table.

Xiao Chen picked up the magazine and flipped through it, and Song Feipeng explained: "There may be DNA of the deceased on it, phosphor was found at the scene, and it is also in the book, which may have been brought by the murderer." ”

Xiao Chen nodded, "You check, what time was the deceased's dinner, which is conducive to further determining the time of death." ”

"OK, I'll go first!"

Song Feipeng lit a cigarette and left in a hurry, Xiao Chen saw the fried dumplings on the table, and smiled helplessly.

The next day, the investigation continued.

The officers reported their findings to Seinfeld.

Wang Bing said: "Feng Shuai told me that on the day of the incident, he and Liu Jia had a quarrel, because Liu Jia's uncle promised to transfer them to No. 1 Middle School, but he never fulfilled his promise, and Feng Shuai was a little dissatisfied. ”

Song Feipeng said curiously: "Is their relationship good?" ”

Wang Bing replied seriously: "Three sentences are inseparable from Liu Jia's uncle, I think Feng Shuai loves her uncle more." ”

Seinfeld was amused, "And then? ”

Feng Shuai promised to take Liu Jia to eat sukiyaki pot in the evening, Feng Shuai has a Volkswagen, which is not usually driven, and lent it to his buddies, he went to ask for a car after work that day, because some things were delayed, and he didn't arrive until eight o'clock. He said that he couldn't contact Liu Jia, thinking that Liu Jia was still angry with him and turned off his phone, so he left. ”

"Was the car parked outside or inside?"

"Outside, he walked into the school, and the janitor saw him."

"Didn't he go to Liu Jia's office?"

"And when he said that he went, he saw that the light was dark inside, and the door was locked, and he left."

"The specific time is ......"

"Eighty-forty!"

Song Pengfei leaned back in his chair and integrated Feng Shuai's testimony in his heart, the temperature at the scene was controlled, so the time of death was possible from eight to nine o'clock.

Feng Shuai's suspicion in his heart was not high, but he must still be investigated, Song Pengfei confessed to Wang Bing: "Verify Feng Shuai's testimony!" ”

"Okay!" Wang Bing didn't leave immediately, "Captain, I have an immature suggestion. ”

"You say."

"Is it possible to find out the family of the student who was paralyzed by the deceased?"

"Why?"

"I looked at the autopsy report, and the two blows to the spine seemed to be revenge from the murderer, and the student was also injured in the spine."

"Well, I'll think about it!"

More than one police officer put forward this motive, thinking that it was revenge, and Song Pengfei called the hospital to ask, the child's condition has improved this year, and the speculation of retaliation seems a little untenable.

Liu Jia's popularity among teachers is not very good, and there are many people who secretly hate her, Song Pengfei feels that it is better to dig out the clues on the deceased first.

As soon as Wang Bing left, two policemen came in to report, one of them said that he had checked with a technician, and the air conditioner had indeed been used recently, and it was April now, and the spring flowers were blooming, and the air conditioner was not needed, so it should have been opened by the murderer on the night of the murder.

"Clever fellow!" Song Pengfei muttered.

Last Tuesday, Liu Jia had insulted a boy in class 5 who had not done his homework, and the boy had a few rebumps, which made Liu Ran angry and asked Feng Shuai to take the boy to the playground to punish him for running.

On Wednesday, she also saw a girl in class 4 wearing nail polish, sneering a few words, the girl was thin-skinned and did not come to class in the afternoon, Liu Jia called the girl's parents to explain the situation.

On Wednesday afternoon, a boy was half an hour late and was punished by Liu Jia, and Teacher Zhang, who was passing by, warned Liu that it was not good to punish students in the corridor, which belonged to corporal punishment of students, so that the leader seemed to be about to speak, Liu Jia choked Teacher Zhang a few words, which probably meant "My students want you to take care of it".

Teacher Zhang is a famous female teacher of English, Chinese New Year's Eve this year, the children are all teenagers, she kindly reminded Liu Jia but was choked by her, so that Teacher Zhang felt very humiliated, she complained about this with a few good colleagues, everyone said that Liu Jia has always been arrogant, it is best to stay away from her.

On Friday, at the faculty meeting, Liu Jia was absent without reason.

On Saturday morning, Liu Jia was late, and when the school worker Lao Wang saw her, he saw that her eyes were black, as if she was still a little hungover, but she didn't say it but thought in her heart, this female teacher was too imageless.

On Saturday morning, Liu Jia confiscated the diary of a female student in class 4, this female student is the representative of the Chinese class in the class, and her grades are also good.

These are Liu Jia's "deeds" in the past week, Song Pengfei listened to it and asked: "Diary?" I didn't see it in the deceased's personal belongings. ”

The police officer who reported the case said: "The students leave school at 11:30 p.m., or I will run again." ”

"No need, I'll go by myself!"
