It is reported that police officers from the Huancui Branch of Weihai Public Security Bureau in Shandong Province quickly investigated and solved a gold theft case, and recovered more than 4 million yuan worth of gold jewelry within 12 hours. On the early morning of July 21st this year, a jewelry store in Huancui District, Weihai City was robbed, and gold jewelry worth more than 4 million yuan was looted. That morning, the jewelry store staff reported the theft to the police before entering the store. After receiving the alarm, the police officers of Huancui Sub bureau quickly responded and conducted on-site investigation and case investigation. The stolen jewelry store covers an area of 30 square meters and is equipped with 12 cameras from the entrance to above the counter. These cameras record the crime process of the suspect. Through video playback, it can be seen that in the early morning of that day, a man wearing a hat and mask, a dark round neck short sleeved shirt on the upper body, dark pants on the lower body, and dark sports shoes on the feet opened the electric roller shutter door and smashed the glass of the store door with a hammer to enter the jewelry store. After entering the store, the man did not commit theft immediately, but confirmed that there was no one around and put down the rolling shutter door. He held his phone and looked at each one with the light of his flashlight, taking whichever was expensive. He took away the emerald ring and dozens of bracelets, "said Ms. Bai, the owner of the stolen jewelry store. According to Ms. Bai's estimation, the stolen gems, gold, pearls, watches, etc. are worth over 4 million yuan in total. "The scene was very chaotic, with glass fragments all over the floor and many jewelry boxes on the ground. The suspect made full camouflage when committing the crime, which increased the difficulty of investigating and extracting physical evidence." Pu Shengxu, Deputy Commander of the Criminal Investigation Brigade of Huancui Sub bureau, said. Subsequently, the police selected multiple locations such as the inside of the counter and the edge of the counter sliding door for investigation and collection. After laboratory testing, several valid physical evidence were detected. After excluding the clerks, it is judged that the remains of these effective inspection materials are the same person, who is likely to be the suspect of the case. How to obtain more effective information from the scene to promote case solving? When reviewing the video of the crime scene for many times, the police handling the case found that the suspect smashed the glass with a hammer before entering the shop. Since the time of the crime was in summer, the suspect's clothes were thin. When entering the broken glass door, he was likely to be scratched by glass fragments, leaving blood stains. Based on this analysis, we focused on searching for bloodstains and conducted a carpet like survey, ultimately discovering a red spot of only 1 millimeter on a jewelry box under the counter. In order to determine whether it was a bloodstain, the police immediately sent it to the laboratory for examination and found that the bloodstain was left by the same male as several previous biological evidence Pu Shengxu said. With the discovery and comparison of physical evidence at the scene, the suspect is locked. The police found in the video tracking of the suspect's escape route that the suspect had entered a parking lot and then drove away. His modus operandi was quite clear, and upon arriving at the scene, he went straight to the target. Based on this information, we conclude that he may have conducted reconnaissance on the scene Analysis by Tang Meng, Deputy Captain of the Criminal Investigation Brigade of Huancui Sub bureau. Subsequently, the police traced all the previous videos and found that a man wearing white clothes and the car owner's photo taken at the exit of the parking lot were the same person. Ten hours after the report, the police locked the identity of the suspect. Within 12 hours of reporting the case, the police launched an arrest and will apprehend Yu. After being arrested, Yu firmly refused to disclose the details of the crime. In the end, in the face of various evidence presented by the police, Yu confessed his illegal facts.
