After the police determined the scene of Dao Youcheng's first killing, the people of the forensic department finally came late, and under Wen Jianren's constant urging, the forensic department had to improve efficiency, and it only took two hours to determine the cause of Dao Youcheng's death, and Dao Youcheng was beaten to death by a group.

It's a group fight.

The forensic department found multiple wounds on Dao Youcheng's chest, eight broken ribs, these wounds were of different sizes and different forces, and the forensic doctor of the forensic department determined that this should be an injury caused by the strength of different people's fists.

According to the location of the fist wound on Dao Youcheng's body, and the height of Dao Youcheng, the people of the forensic department roughly judged the height range of the five murderers who beat Dao Youcheng, which greatly narrowed the scope of the police investigation.

Li Er witnessed the ability of the Forensic Section to restore the facts of the case, and couldn't help but feel a pang in his heart, he is going to become the King of the Pirates, ahem, he is a man who wants to become the King of Assassins, and the Forensic Department of a subdivision is already so bullish, so aren't all the Forensic Departments of the Region all forensic pioneers?

hit the street, and sooner or later he will be killed by the bastard system.

"Hey, man, what do you call it?" Li Er said with a smile to a little fat man in the forensic department.

"Gao Yanbo!" said the little fat man with a straight face.

"Oh, sir, can you find the murderer's fingerprints, DNA or something?" asked Li Er curiously.

The little fat man Gao Yanbo looked at Li Er in surprise: "This sir seems to know a lot about forensics?"

Li Er shook his hand and smiled: "Curious, purely curious, I've watched too many movies." ”

The little fat man nodded: "The body of the deceased was washed by sewage in the sewage canal, even if there are murderer's fingerprints on the body, it has long been destroyed, and the fingerprint database of our police department is too small, only criminals who have a criminal record have fingerprints, and it is not of much use to your detective department if they find out." ”

In fact, there is one thing that the little fat man didn't tell Li Er, whether it is fingerprint comparison or DNA testing, it costs money.

In this era, the police department did not attach importance to the forensic department, and the budget allocated to the forensic department every year was extremely low, and the bosses of the forensic department also restrained their subordinates, and they would not do things if they could not do things, and not every department had a sand sculpture like Li Yunying who paid out of his own pocket.

At this time, a police officer in the CID department bought a box lunch and water for everyone according to Wen Jianren's instructions, and it seemed that he planned to let the CID police officer start work immediately after eating.

Li Er opened the lunch box and took a look, it was a barbecued pork and roast duck lunch, he had just seen the corpse of Dao Youcheng, he had no appetite at all, and he had drilled through the sewage drain, and his whole body was stinky, Li Er handed the lunch box to the little fat man in the forensic department who was swallowing saliva.

"Don't you, I've just seen dead bodies and have no appetite!"

The little fat man hurriedly took it and smiled happily: "It's just right, I didn't eat breakfast in the morning, thank you!"

Although Wen Jianren is not as picky as Li Er, he will not spend the budget of the CID department to buy boxed lunches from other departments, and if it is not for continuous work, he would even prefer to let his subordinates disband and come back after lunch.

"Li sir!" The little fat man in the forensic department looked at the police officer card that Li Er was clipped to his chest.

"If you look at the shoe prints on the ground, these two pairs are the most common slipper soles, and these two pairs of shoe prints have been repeatedly stepped on many times, and it is difficult to extract the lines, but ——!" the little fat man said here, he deliberately paused: "I know the last pair of shoes." ”

Li Er: "......"

The little fat man said and lifted his overalls leather shoes: "This is the same style of shoes as me, and this is a size 12 shoe, there are not many people with such big feet, usually people who are more than 1.8 meters tall, and help you eliminate a large number of suspects." ”

The little fat man squeezed his eyebrows, with an expression that I didn't eat your lunch box in vain.

Li Er nodded, and secretly said in his heart that he must not buy unconventional shoes in the future.

The little fat man seemed to be rarely nagged so seriously, and he couldn't help but continue to whisper to Li Er: "Sir Li, if you really arrest this group of murderers, be careful, they just killed someone, it is when the anger is the heaviest, at this time they are fearless, break the jar and fall, dare to do anything, and will definitely fight to the death with you." ”

Li Er was stunned, glanced at the little fat man carefully, and asked, "How do you know this?"

"Reading books and observing, there are a lot of old cases in our police force, looking at all the homicide cases, criminals are very panicked when they have just killed someone, they usually find a righteous excuse to convince themselves that they are passive killings, and at this time they will fight to the death with the police to prove that they are right. The little fat man said seriously while picking up rice.

"Then what if we arrest them after a while?" Li Er asked in disbelief.

The little fat man smiled affirmatively: "If it drags on for a long time, those criminals will find that they have not received the punishment they deserve, and they will have a fluke mentality, which is the inferior nature of human nature, no one can escape, and then meet the police at this time, the first thing they think about is not to desperately, but to flee, and it is safe for you to arrest people at this time." ”

The little fat man in the forensic department said one thing at a time, and he bluffed Li Er into a daze.

"Why don't you write your discovery about the pattern of shoe prints in the appraisal report?" asked Li Er.

The little fat man laughed in a low voice: "I'm not stupid, these are speculations, all speculations, no matter how rigorous, there is a chance of mistakes, this kind of murder case, it is the credit of your CID to solve it, our forensic department can't get anything, in case the circumstances of the case change, you don't want to put the responsibility on us, the less you do, the fewer mistakes you make, our forensic department don't bear this pot for you, don't you find that the forensic reports issued by our forensic department are extremely concise? This is for you to be ridiculed in the future." ”

Sure enough, ten fat people, nine cheap ones.

Li Er couldn't help but give the little fat man a middle finger.

Li Er suddenly remembered that the work efficiency of the forensic department was extremely low, and now it seems that they may have deliberately delayed until that time, and the case was solved, and they issued an appraisal certificate, naturally there was no flaw, and sure enough, every department has an unspoken rule for the operation of each department, which is really a hit.

After speaking, the little fat man smiled and pointed to the mineral water in Li's second-hand, Li Er threw the mineral water he hadn't drunk speechlessly, this little fat man is not only cheap, but also likes to take advantage of small advantages.

"Thank you Sir Li!" The lunch box bought by CID was too salty, and the little fat man hurriedly poured a sip of mineral water.

On the other side, Wen Jianren has already begun to assign tasks.

Wen Jianren: "Li Er, is there any problem with you and Ah B being in charge of the first to five estates in the upper village?"

"YES, SIR! Li Er replied decisively.

On this occasion, even if Li Er really has a problem, he will not immediately refute Wen Jianren, at most he will put forward his opinion to Wen Jianren after the meeting, which is one of the reasons why Wen Jianren likes a guy like Li Er.

"Ah B, I just got some information, maybe it will be useful, the murderer may be a small group of five people, one of them is tall and wears size 12 shoes, do you have a clue?" Li Er knew that Li Xunying knew a wide range of things, and he had dealings with all three sects and nine streams, so he asked him in a low voice.

"A handful of five people, that's a group of gangsters who don't enter the stream. Li Yunying frowned and thought for a while, and suddenly his eyes sharpened: "Hei Zaiwen, they often beat Dao Youcheng, but he only has three subordinates, and there are no big ones." ”

"Hey, Brother B, what are you doing with so many bad guys around the head of the banyan tree?" was Hei Zaiwen's voice, which was really a coincidence.

Hei Zaiwen held an ice cream in his mouth, pulled his shirt under his armpit and clamped it, and walked towards Li Xunying with a ruffian face.

Wen Jianren saw that Li Xunying and Gu Chao Zai were intimate, and his face suddenly turned gloomy.

Li Xunying's eyes flashed, and he suddenly stretched out his hand and pointed at Hei Zaiwen and shouted: "Hei Zaiwen, someone saw that you killed Dao Youcheng yesterday, and you are dead." ”

Hei Zaiwen's face changed, then he turned around and began to run wildly.

All the CID officers present were stunned by Hei Zaiwen's sudden escape.

"Yan Jiashovel, it's really you!" Li Xunying had already chased after him angrily.

Li Er reacted quickly, Li Xunying was cheating on Hei Zaiwen just now, but he didn't expect that the murderer was really him, and he also chased after Li Xunying.

Wen Jianren was overjoyed, he saw Li Xunying and Li Er chasing Hei Zaiwen, even if it was a pig, he understood what was going on.

"Quick, chase me all, you must catch that bastard for me!" Wen Jianren shouted excitedly.

Hei Zaiwen is often chased by the police, and he practices very quickly, but fortunately, Li Xunying is not slow and bites Hei Zaiwen's back tightly.

Li Er started very fast, but after chasing three or four hundred meters, he ran out of breath, sweating profusely, and at the same time his ribs hurt in a panic.

"Wait, Li Xiuxian pursued the prisoner Hei Zaiwen in the estate. Li Er looked at the backs of Li Xunying and Hei Zaiwen, and suddenly a spirit, he suddenly remembered which movie was this, this is "Public Servant", wait a minute, Li Xiuxian is about to kill a little boy by mistake.

"Hei Zaiwen, you can't escape, stop me immediately. Li Xunying shouted angrily while chasing after him.

When Hei Zaiwen heard Li Xunying's words, he didn't dare to stop, and just ran wildly.

"Ah B, Ah B, you stop!" Li Er endured the sharp pain in his abdomen, and chased after Li Yunying with a breath.

Li Xunying heard Li Er's call, but it was important to arrest people, he didn't stop, but accelerated his pace, and Li Er was even more difficult to catch up with him.

"Ah B, fuck your mother, stop, I'm running out of breath. Li Er held down his stomach and chased wildly, while scolding: "Don't shoot, don't shoot, hit the street!"

As soon as Li Er's words fell, Li Xunying had already drawn his gun.

Because Hei Zaiwen pushed down several passers-by when he was escaping, one of the elderly people was pushed down the stairs by Hei Zaiwen, and his head was broken and bleeding in an instant.

Hei Zaiwen turned an alley, Li Yunying turned around without hesitation, and the two disappeared in front of Li Er's eyes.

"Bang ——!"

A gunshot rang out.

Li Er's heart was cold, he only hoped that his butterfly wings were big enough.
