After the police identified the first murder scene of Dao Youcheng, the forensic department finally arrived late. Under Wen Jianren's constant urging, the forensic department had to improve its efficiency, and it only took two hours to determine. Knowing the cause of Dao Youcheng's death, Dao Youcheng was beaten to death by a group.
It's a gang fight.
The forensic department found multiple wounds on Dao Youcheng's chest, eight broken ribs. These wounds were of different sizes and exerted different strengths. The forensic doctor of the forensic department determined that these injuries should be caused by different people's fist strength.
Based on the location of the fist wound on Dao Youcheng's body and the height of Dao Youcheng, the people of the forensic department roughly determined the height range of the five murderers who beat Dao Youcheng, which greatly narrowed the scope of the police's investigation.
Li Er saw with his own eyes the ability of the forensic department to restore the case, and he couldn't help but sigh in his heart. He is going to become the king of pirates, ahem, he is the man who wants to become the king of assassins. The forensic department of a division is already so arrogant. Aren't the district's forensic departments all forensic pioneers?
Throwing on the street, sooner or later, you will be killed by the bastard system.
"Hi! Dude, what's your name?" Li Er smiled and said to a little fat man in the forensic department.
"Gao Yanbo!" The little fat man said with a straight face.
"Oh! Sir Gao, can you find the fingerprints, DNA or something of the murderer?" Li Er asked curiously.
Fatty Gao Yanbo looked at Li Er in surprise: "This Asir seems to know a lot about forensics?"
Li Er waved his hand and smiled: "Curiosity, pure curiosity, I've watched too many movies."
The little fat man nodded: "The body of the deceased was washed by sewage in the sewage canal, and even if there were fingerprints of the murderer, it would have been destroyed long ago, and the fingerprint database of our police department is too small, only criminals who have a criminal record have it. The fingerprints left behind will not be of much use to your detective department."
In fact, there is one thing that Little Fatty didn't tell Li Er, whether it is fingerprint comparison or DNA testing, it costs money.
In this era, the police department does not pay much attention to the forensic department. The budget granted to the forensic department every year is extremely low. The boss of the forensic department also restrains his subordinates. The sand sculpture of the slender eagle that pays for itself.
At this time, a police officer from the CID department bought lunch boxes and water for everyone according to Wen Jianren's instructions. It seems that he planned to let the CID police officers start work immediately after eating.
Li Er opened the box and looked at it. It was a boxed lunch with barbecued pork and roasted duck. He had just seen Dao Youcheng's corpse, and he had no appetite at all. He also got through the sewage canal, and his whole body was stinking. Li Er handed the box lunch to Zheng Zheng. The forensic little fat man.
"Would you like it, I just saw a dead body and lost my appetite!"
The little fat man quickly took it and smiled happily: "Just right, I didn't eat breakfast in the morning, thank you!"
Although Wen Jianren is not as stubborn as Li Er, he will not spend the budget of the CID department to buy lunch boxes from other departments. If it is not for continuous work, he would even prefer to let his subordinates disband and have lunch and then come back to concentrate.
"Li sir!" The little fat man in the forensic department looked at the police ID card Li Er was holding in front of his chest.
"Look at this shoe print on the ground. These two pairs are the most common patterns on the soles of slippers, and these two pairs of shoe prints have been repeatedly stepped on, so it is difficult to extract the patterns; but—!" The little fat man said here When I stopped on purpose: "I know the last pair of shoes."
Li Er: "..."
The little fat man said and lifted his leather work shoes: "This is the same style of shoes as mine, and it is a shoe size of 12. There are not many people with such big feet, usually people who are over 1.8 meters tall. It helped you rule out a lot of suspects again.”
The little fat man winked with an expression like I didn't eat your lunch for free.
Li Er nodded, secretly thinking that he must never buy unconventional shoes in the future.
It seems that the little fat man rarely listened to him so seriously, he couldn't help but continued whispering to Li Er: "Li sir, if you really arrest this group of murderers, be careful, they just Killing people is the time when the anger is the heaviest, and at this time they are fearless, break the jar, and dare to do anything, and they will definitely fight to the death with you."
Li Er was stunned, looked at the little fat man carefully, and asked, "How did you know this?"
"Reading books and observations, we have a lot of old cases in the police force. Looking at all murder cases, criminals are very panicked when they just kill someone. They usually find a just excuse to convince themselves that they are passive murderers. At this time, they will fight with the police, and they will resist desperately to prove that they are right." The little fat man said earnestly as he cooked rice.
"Then what if the arrest is made after a period of time?" Li Er asked in disbelief.
The little fat man smiled affirmatively: "If it drags on for a long time, those criminals will take a chance when they find that they have not received the punishment they deserve. This is the bad nature of human nature, and no one can escape, and they will encounter the police again at this time. , their first thought was not to fight hard, but to run for their lives, but it is safe for you to arrest people at this time."
The little fat man in the forensics department said one thing, and Li Er was stunned for a while.
"Why don't you write your findings about the pattern of shoe prints in the appraisal report?" Li Er asked.
The little fat man smiled and said in a low voice: "I'm not stupid, these are all speculations, any speculation, no matter how rigorous, has a chance of error, this kind of murder case, it's your CID's credit, what about our forensics department? If the case changes, you don't want to put the blame on us. The less you do, the less mistakes you make. Our forensics department should not take the blame for you. You didn't find that our forensic department issued Are all of the forensic reports as concise as possible? This is for the sake of arguing with you in the future."
Sure enough, ten fat people and nine cheap ones.
Li Er couldn't help showing the little fat man a middle finger.
Li Er suddenly remembered that the work efficiency of the forensic department is extremely low. Now it seems that they may have deliberately delayed until that time, and the case has been broken. When they issue the identification certificate, they will naturally have no flaws. Sure enough, every department has There are unspoken rules for the operation of each department, which is really a hit.
The little fat man smiled and pointed to the mineral water in Li's second hand. Li Er silently threw the mineral water he hadn't drunk before. Not only was this little fat man cheap, he also liked to take advantage of it.
"Thank you, sir!" The lunch box CID bought was too salty, and the little fat man hurriedly took a sip of mineral water.
On the other hand, Wen Jianren has already begun to assign tasks.
Wen Jianren: "Li Er, you and Ah B are in charge of the one to five housing estates in the upper village. Is there any problem?"
"YES, SIR! No problem." Li Er replied decisively.
On such occasions, Li Er would not immediately refute Wen Jianren even if he had a problem, at most he would give Wen Jianren an opinion after the meeting. This is one of the reasons why Wen Jianren likes a guy like Li Er.
"A B, I just got some information, it may be useful. The murderer may be a small group of five people. One of them is tall and wears 12-size shoes. Do you have any clues?" They have been dealing with each other, and asked him in a low voice.
"A group of five people is a small group of gangsters." Li Xianying frowned and thought for a while, and suddenly his eyes turned sharp: "Hei Ziwen, they often beat Daoyoucheng, but he only has three subordinates, so he No big ones."
"Hey! Brother B, what are you doing around the head of the banyan tree?" It was Hei Ziwen's voice, which was a coincidence.
With an ice cream in his mouth, Hei Zaiwen pulled his jacket to his armpit and walked towards Li Xianying with a sullen face.
Wen Jianren's face suddenly darkened when he saw that Li Xianying was intimate with Young and Dangerous.
Li Xianying's eyes flashed, and suddenly he pointed at Hei Zaiwen and shouted loudly, "Hei Zaiwen, someone saw that you killed Dao Youcheng yesterday, you are dead."
Hei Ziwen's face changed, then he turned around and started running wildly.
All the CID police officers present were stunned by Hei Ziwen's sudden escape.
"Xian Jiasho, it's really you!" Li Xianying had already chased after him angrily.
Li Er quickly reacted, Li Xianying was cheating Hei Zaiwen just now, but he didn't think the murderer was really him, so he also chased after Li Xianying.
Wen Jianren was overjoyed. He saw Li Xianying and Li Er chasing Hei Zaiwen, and even the pigs understood what was going on.
"Quick, chase them all for me, be sure to catch that bastard for me!" Wen Jianren shouted excitedly.
Hei Zaiwen was often chased by the police, and he practiced very fast, but fortunately, Li Xianying was not slow, biting tightly behind Hei Zaiwen.
Li Er started very fast, but after chasing three or four hundred meters, he was out of breath, jogging sweating profusely, and at the same time the pain in his ribs was also panicking.
"Wait, Li Xiuxian is chasing the prisoner Hei Zaiwen in the housing estate." Li Er looked at the backs of Li Xianying and Hei Zaiwen, and suddenly agitated, he suddenly remembered which movie this happened, this is "Public Servant", Li Xiuxian was about to accidentally kill a little boy.
"Hei Ziwen, if you can't escape, stop for me immediately." Li Xianying shouted angrily while chasing him.
Hei Ziwen didn't dare to stop when he heard Li Xianying's words, and just ran wildly.
"A-B, A-B, hurry up and stop!" Li Er endured the severe pain in his abdomen and hurriedly chased after Li Xianying while holding his breath.
Li Xianying heard Li Er's call, but it was important to catch someone. He did not stop, but quickened his pace, making it even more difficult for Li Er to catch up with him.
"A-B, I'm fucking your mother, stop now, I'm running out of breath." Li Er scolded while holding his stomach and chasing: "Don't shoot, don't shoot and rush into the street!"
As soon as Li Er's voice fell, Li Xianying had already drawn his gun.
Because Hei Zaiwen pushed down several passersby when he was escaping, and one of the elderly was pushed down the stairs by Hei Zaiwen, and his head was broken in an instant.
Hei Zaiwen turned an alley, Li Xianying turned around without hesitation, and the two disappeared in front of Li Er's eyes.
"Bam—!"
A shot rang out.
Li Er felt a chill in his heart, he only hoped that the wings of his butterfly were big enough.
