"What's the most urgent case right now?" Shen Long took the information and asked, seeing these materials, he already knew the plans of Li Mingjian and others, but he didn't care, Li Mingjian and the others wanted to suppress themselves through the case, and he agreed that he needed to establish his prestige by solving the case.

If we can crack the big and important cases that have plagued the criminal police detachment of the Luzhou City Public Security Bureau for a long time in a short period of time, I believe that the criminal police team will definitely change its opinion of itself, and in this line of work, after all, we still have to talk about solving cases, as long as you can solve the problems that they can't solve, the prestige will soon be established.

On the contrary, no matter how fanciful you say, if the case can't be solved, then I'm afraid you won't be able to stay here for long, Li Mingjian and even Liang Qunfeng have good reasons to drive you away.

"7.23 burglary and homicide case, a mother and son were killed in a rental house, because the murderer's methods of committing the crime were very cruel, which caused a very bad social repercussions, but we did not find any useful clues at the scene, so the case could not be solved for a long time, and the superior leaders and the people of Luzhou City had great opinions about us." Said the policeman who delivered the information.

"Okay, I'll take a look at this information first, you go out and inform the comrades who were in charge of this case before, and I will go to the scene with them after reading the information in a while." Shen Long opened the information that read the 7.23 burglary and murder case and said.

"Well, okay, I'll go and inform them." Jiang Linhai wanted to speak and stopped, more than ten days have passed since the incident, and they have gone to investigate countless times at the scene, what can he see as a layman who graduated from the Department of Political Science and Law?

An hour later, a police car drove out of the Luzhou City Public Security Bureau, in addition to Shen Long, there were several criminal policemen in charge of the case, the team was led by the old criminal policeman Liu Hongsheng, and the remaining two young criminal policemen had just graduated from the police academy for less than two years, one was named Chen Wenqing and the other was named Li Qi.

"The scene of the crime is a rented house on the street near the Chengbei Wholesale Market, where the composition of people is complex, and there are not many traces of the murderer left at the scene, so the case is in a predicament." Liu Hongsheng told Shen Long about the difficulties of this case, during the day on July 23, the male owner of the family went to work in the wholesale market as usual, his wife and son stayed in the house, and when he came back from work, he found that his wife and son were lying in a pool of blood, the necks of the two deceased were cut to death by sharp knives, both were tied, and there were no traces of fierce fighting in the rental house.

"According to my years of experience in handling cases, the murderer easily tied up the mother and son, which shows that the strength of the two sides is very different, and it is very likely that an adult man committed the crime; There are traces of rummaging through the finances at the scene, and it can be inferred that it was murdered for money, and after rummaging through the property, they were afraid that the mother and son would report the case and expose themselves, so they killed them. These analysis materials are available, but Liu Hongsheng didn't dare to guarantee how much Shen Long had watched, so he said it again.

"After the case, we visited the surrounding residents and locked up a few suspects who passed by the scene at the time of the crime, but due to the lack of evidence, we have not been able to find out who is the murderer." Because the level of science and technology is not high, the current means of handling criminal cases are still relatively simple, and large-scale investigation is a common method, and Liu Hongsheng's handling method is decent from the current situation.

Shen Long rarely spoke all the way, just listened carefully to Liu Hongsheng's report; Now there are not many vehicles on the street, there is no traffic jam, it didn't take long for the police car to arrive at the scene, the scene is still out of blockade, seeing the police car coming, the surrounding residents let out cynicism.

This is not to blame them, anyone who has a criminal case around them will be worried, and now that the murderer has not been caught, the neighbors on the left and right will naturally worry about whether they will become the next victim.

"It's the room up ahead." Liu Hongsheng pointed to the sealed house and said, this is a hollow brick house built privately, there are many such buildings around, and there is a row of black locusts planted in front of the house, which is the most common street tree in Luzhou City.

"Because the wholesale market has been very prosperous in the past two years, people in the vicinity have built a lot of these houses for rent, and the neighbors have gone to work in the wholesale market during the day, and there were no witnesses at the time of the incident." Liu Hongsheng asked Chen Wenqing and Li Qi to take off the seal and prepare to take Shen Long in, but when he turned around, he saw Shen Long smoking on the street tree at the door of the house, looking thoughtful.

"Alright, let's go inside!" After smoking, Shen Long entered the rental house, only to see that the walls and floors in the room were covered with dried blood spots, which showed the tragedy at the time of the crime.

"I've seen it many times, and I've looked for all the places I can find, and I haven't found any clues, Captain Qi, you can look around, and you can ask me at any time if you have any questions." Liu Hongsheng has been here many times, but he really doesn't think that Shen Long can make any new discoveries.

"Well, I'll take a look!" Shen Long was careful not to spoil the scene with his movements, and slowly walked around the room a few times.

The house is not big, there is a bedroom inside, and there is a living room and kitchen outside, the economic conditions of the tenants are not very good, the living room has only a dining table and a few chairs, and there is an ashtray and rotten food on the table, even such a family will be robbed, it seems that the murderer is really poor.

Seeing Shen Long stop, Liu Hongsheng asked expressionlessly, "Captain Qi, what did you find?" In fact, he didn't think Shen Long could find anything, he had been a criminal police officer for more than ten years, and he had come to see it many times but didn't find it, what could a layman who graduated from a political science and law major on the other side see?

Shen Long pointed to the ashtray on the table and asked, "Has it been touched here?" ”

There are also a few cigarette butts in the ashtray, and judging from the filter, it is the most popular red plum cigarette in the local area.

"No, according to our investigation, the man of this house likes to smoke, and these cigarette butts should have been left by him." Liu Hongsheng replied.

"Just should? I don't think so. Shen Long took out the white gloves and put them on, took out a plastic bag specially designed to preserve the evidence, and carefully picked up a few cigarette butts with tweezers and put them into the plastic bag.

"Alright, let's go back!" Shen Long kept the cigarette butts and turned around and walked out of the scene of the crime, the purpose of this scene investigation has been achieved, and he can go back.

"This is going back?" Liu Hongsheng was stunned, how long has it been since he came? Grab a few cigarette butts and go back? This Captain Qi is too much, right?

"Well, I've found the clue." Shen Long replied, "The murderer is among the suspects you have locked. ”
