Watch your back! The key to solving the case is to rob cigarette butts with a knife in the shadow of the corridor

　　　　　　 CCTV News:Recently, in Qingshan District, Baotou City, Inner Mongolia, there have been several vicious cases in which strange men followed lone women late at night and robbed them with knives. The targets chosen by men are single women who walk alone, and the suspects in each robbery are armed with sharp knives. So what are the hidden secrets behind these cases?

　　　　　　 What’s the secret behind the two robberies?

　　　　　　 At eleven o’clock on the evening of March 30th, Ms. Wang returned to her residential area after work in the middle of the night. Just as she entered the corridor of the unit building, a cold sharp knife bypassed behind her and stopped at her neck. A strange man’s voice came from behind and asked her for property. Ms. Wang fiercely resisted, and her head and arms were scratched by the sharp knife held by the suspect. The suspect fled.

　　　　　　 A wave of unrest, another wave. Shortly after this case, another woman reported that she was robbed and almost raped.

　　　　　　 The police found that the two cases occurred less than one kilometer apart. According to the two victims, the perpetrators were carrying a shoulder bag and holding a black dagger in their hands. At the same time, there is a very important clue, that is, the police extracted the cigarette butts of the same brand of cigarettes at two crime scenes. All these signs indicate that these two cases of armed robbery are most likely committed by a suspect.

　　　　　　 Can the three groups of police officers attack separately and lock the target?

　　　　　　 After a comprehensive analysis of the two cases, considering the social impact and urgency of the case, the task force decided to divide into three groups, and at the same time, it collected and judged the route of the suspect before he arrived at the first crime scene, the trajectory of the suspect from the first crime scene to the second crime scene, and where the suspect went after leaving the second crime scene.

　　　　　　 Because the road monitoring conditions around the first community are not complete, and the time of the incident is late at night, the surrounding businesses have closed, and the first group of police can not get the social monitoring screen at the first time. Therefore, the clue of trying to trace the suspect’s route was interrupted.

　　　　　　 The second group of police analyzed and sorted out several feasible routes from the first crime plot to the second crime plot, and collected the monitoring of all feasible routes for judgment. After more than ten hours of video tracking, the police really found the picture of the suspect leaving the first community and walking to the vicinity of the second community.

The police found the suspect.

　　　　　　 After determining that the suspects in the two cases were the same suspicious man, the third group of police took the second crime scene as the center and collected a large number of surveillance videos to track the way of the suspects after leaving the second community. When the third group of policemen tracked all the way to the vicinity of a university in Qingshan District, four days had passed since the incident.

　　　　　　 Looking around for surveillance, I finally found the suspect.

　　　　　　 Because time was short, and the suspect finally disappeared on a main road, the police decided to change their minds and get the traffic probe on the main road, because the coverage of the traffic probe would be much larger than that of the social probe. Subsequently, the police seized a lot of surveillance around and found no suspects. The police concluded that the suspect probably found a foothold nearby that night.

The police conducted a visit to suspicious areas.

　　　　　　 Hard work pays off, and finally the police saw the suspicious man in the surveillance screen of an Internet cafe. Through the online records of Internet cafes, the police identified the suspect as Liu, a 25-year-old from Haibowan District, Wuhai City, who has no fixed job or residence in Baotou. After the police brought Liu back from Baotou Railway Station, after the trial, Liu confessed to his criminal facts.

　　　　　　 During the interrogation, the suspect Liu also confessed that he also committed another robbery about a week before the incident.
