Attending ex-girlfriend's wedding, arresting the groom's officer on the spot

In the employee locker room, Wang Shuai put on latex gloves and used tweezers to pick up a half-smoked cigarette butt in the corner of the locker. The tobacco was mixed with light pink lipstick marks, the same color as Wang Yaoyao's lipstick. The escort Xiaomei suddenly rushed in and grabbed his wrist, leaving red marks on the skin with her nails: "Don't check! You can't beat them!" As she hurriedly stepped back, the fresh scratches on her collarbone were faintly visible, overlapping in Wang Shuai's mind with the skin tissue sample between the fingernails of the deceased in the forensic report. Even more suspicious was that the four-leaf clover necklace Xiaomei wore around her neck was exactly the same style as the birthday gift in the photo on Wang Yaoyao's social account.

Although the surveillance footage of the club's back door was deleted, the technical department restored some footage overnight. In the footage, at 10:14 p.m. on October 11, a black Maybach stopped at the fire escape. A man wearing a baseball cap opened the trunk, revealing a corner of off-white fabric - the same material as the dress Wang Yaoyao was wearing when she disappeared. The license plate number was covered in mud, but in the blurred reflection captured by the dashcam, the person in the passenger seat was wearing the same Patek Philippe watch as the manager. When Wang Shuai zoomed in on the footage, he found that the person in the reflection of the car window had a dark red mole behind his ear, which was exactly the same as the feature on the ID card photo of a mysterious VIP guest in the club's consumption record.

The rain was getting heavier. When Wang Shuai and Zhang Hui walked out of the club with their evidence bags, the neon lights of the tattoo shop across the street flickered. In the glass window, Chen Hao suddenly paused while wiping the tattoo machine. He stared at the two people with eyes like a poisoned knife. At this time, under the microscope of the physical evidence department of the Criminal Investigation Brigade, the saliva on the cigarette butt and the skin tissue between the fingernails of the deceased were undergoing a decisive DNA comparison.

The comparison work has reached a deadlock.

Judging from some of the clues found so far, no relevant information about the real suspect has been matched in the system, so we still need to investigate and analyze some of the circumstances around the deceased and some of the circumstances currently discovered in the Paradise Entertainment Club to determine whether it is possible to find the suspect.

In the meeting room of the Criminal Investigation Brigade, the whiteboard was densely covered with photos and information of suspects related to the Paradise Entertainment Club. Lu Chuan pointed a laser pen at the photos and said, "All the suspects we have locked in seem suspicious, but before the truth comes out, we can't miss any details, and we can't wrongly accuse anyone. Now let's start an in-depth analysis and investigation of each suspect."

The first person to be investigated was Zhao Qiang, a man with silver-gray hair and a big gold chain. When Wang Shuai and Zhang Hui arrived at the used car dealership run by Zhao Qiang, it was the busiest time of the afternoon. There were more than a dozen cars of varying conditions parked in the dealership. Zhao Qiang was standing next to a black sedan, bargaining with a customer. When he saw the police coming in, a trace of panic flashed across his face, but he soon smiled again: "Two officers, how come you have time to come here?"

Wang Shuai didn't exchange pleasantries and went straight to the point: "Zhao Qiang, where were you on the night of October 10?" Zhao Qiang scratched his head and said, "I was in the car dealership that night. The guys in the store can testify to this." In order to verify his statement, Zhang Shuai began to question the employees of the car dealership one by one. A young apprentice recalled, "The boss was indeed in the store that night. We were busy sorting out the newly collected cars until the early morning." In addition, Wang Shuai also retrieved the surveillance video near the car dealership, which showed that Zhao Qiang did not leave the car dealership that night. At the same time, the test results of the reddish-brown soil on Zhao Qiang's soles were also released, and they did not match the soil composition of the sculpture base. Based on these evidences, Zhao Qiang's suspicion was temporarily lifted.

Next was the club manager Liu Deming. Lu Chuan personally led the team to his office and asked again about the damage to the surveillance hard drive. Liu Deming still had that smiling face, but he could not hide the tension in his eyes: "Officer Lu, I really didn't lie to you. The hard drive suddenly broke down, and I was very anxious." However, after an in-depth inspection of the hard drive, the technicians found that the hard drive was not damaged naturally, but someone deliberately physically damaged it. This discovery made Liu Deming's suspicion rise sharply. But with further investigation, the police found that Liu Deming destroyed the hard drive because there were some illegal operations in the club, and he was afraid of being found out by the police, and it was not related to Wang Yaoyao's death. By investigating his call records, bank statements, etc., no clues related to the case were found. Moreover, during the time of the incident, he had a clear alibi - he was handling emergency matters at another branch at the time, and several employees could testify. Liu Deming's suspicion was also ruled out.

Although Xiaomei, the escort, behaved very abnormally, after a detailed investigation, it turned out that she had a close relationship with Wang Yaoyao. After Wang Yaoyao disappeared, she was always worried that the murderer would harm her, so she acted so panicked. The police gave her psychological counseling, and Xiaomei let down her guard and told her everything she knew. She confirmed that Wang Yaoyao did plan to leave the club and had discussed future plans with her. The scratches on Xiaomei's collarbone were left during a dispute with another escort and had nothing to do with the case.

The police investigated the social relations and financial status of the security captain Chen Gang and found that he had no sudden large-scale capital changes recently, nor had he interacted with suspicious persons. By questioning his family and friends, they learned that he had always been an honest person. On the night of the incident, he patrolled the club according to the patrol route. The surveillance video (except for the deleted part) and the testimony of other security guards can prove his whereabouts. In addition, he had no intersection with Wang Yaoyao on weekdays and had no motive for committing the crime. Chen Gang's suspicion was also dispelled.

Tattoo shop owner Chen Hao, although he had a grudge against Wang Yaoyao, the police investigated the surveillance of his tattoo shop and the surveillance of surrounding shops and found that he was indeed in the shop on the night of the crime. This was also confirmed by several customers who had tattoos in the shop until the early morning. In addition, the police also tested his tattoo tools and found no blood or traces related to the case. Although Chen Hao was tough, he actually did not have time to commit the crime.

There was also Sun Hao, the man who behaved abnormally in the VIP box and had a ring mark on his ring finger. The police found out that his ring mark was caused by the ring size not being suitable and he had to take it off repeatedly. He was a frequent visitor to the club and was a little flustered when facing the police's questioning because he was just drunk that night. By investigating his mobile phone communication records and social software, no clues related to Wang Yaoyao's death were found. He had been partying with friends in another bar during the time of the incident, which can be proved by the bar's surveillance and the testimony of his friends. (End of this chapter)
